一、繼電器控制電路

能帶動繼電器工作的CMOS集成塊

在人們的習慣中，總認為CMOS集成塊不能直接帶動繼電器工作，但實驗證明，部分CMOS集成塊不僅能直接帶動繼電器工作，而且工作穩定可靠。實驗中所用繼電器的型號為JRC5M－DC12V微型密封繼電器（其線圈電阻為750Ω）。現將CD4066 CMOS集成塊帶動繼電器的工(gong)作(zuo)原理分析(xi)如(ru)下：

CD4066是四雙(shuang)向模擬開關，集(ji)(ji)成塊(kuai)SCR1～SCR4為控制端，用于控制四雙(shuang)向模擬開關的通斷。當SCR1接(jie)高電(dian)平(ping)時(shi)(shi)，集(ji)(ji)成塊(kuai)①、②腳導通，＋12V→K1→集(ji)(ji)成塊(kuai)①、②腳→電(dian)源負極使K1吸合(he)；反之當SCR1輸(shu)入低電(dian)平(ping)時(shi)(shi)，集(ji)(ji)成塊(kuai)①、②腳開路，K1失電(dian)釋放，SCR2～SCR4輸(shu)入高電(dian)平(ping)或(huo)低電(dian)平(ping)時(shi)(shi)狀態與SCR1相同(tong)。

電(dian)路(lu)中，繼(ji)電(dian)器(qi)線(xian)圈(quan)兩端(duan)均(jun)反相并聯(lian)了(le)一只二(er)極管(guan)，它(ta)是用于保護集成(cheng)塊(kuai)的(de)(de)(de)，切不可省(sheng)去，否(fou)則在繼(ji)電(dian)器(qi)由(you)吸合狀態轉為釋(shi)放時，由(you)于電(dian)感(gan)的(de)(de)(de)作用線(xian)圈(quan)上(shang)將產生較高的(de)(de)(de)反電(dian)動勢，極容(rong)易導(dao)致(zhi)集成(cheng)塊(kuai)擊穿。并聯(lian)了(le)二(er)極管(guan)后，在繼(ji)電(dian)器(qi)由(you)吸合變為釋(shi)放的(de)(de)(de)瞬間，線(xian)圈(quan)將通過二(er)極管(guan)形成(cheng)短時間的(de)(de)(de)續流回路(lu)，使線(xian)圈(quan)中的(de)(de)(de)電(dian)流不致(zhi)突變，從而(er)避免(mian)了(le)線(xian)圈(quan)中反電(dian)動勢的(de)(de)(de)產生，確保了(le)集成(cheng)塊(kuai)的(de)(de)(de)安全。

低電壓下繼電器的吸合措施

常常因為(wei)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)低(di)于繼電(dian)(dian)(dian)(dian)器的吸(xi)合電(dian)(dian)(dian)(dian)壓(ya)而使(shi)其(qi)不能正常工作(zuo)，事實上，繼電(dian)(dian)(dian)(dian)器一(yi)旦吸(xi)合，便可(ke)在(zai)額(e)定電(dian)(dian)(dian)(dian)壓(ya)的一(yi)半(ban)左(zuo)右可(ke)靠地(di)工作(zuo)。因此(ci)，可(ke)以在(zai)開始時給(gei)繼電(dian)(dian)(dian)(dian)器一(yi)個啟動電(dian)(dian)(dian)(dian)壓(ya)使(shi)其(qi)吸(xi)合，然后(hou)再(zai)讓(rang)其(qi)在(zai)較低(di)的電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)下工作(zuo)，如圖所示的電(dian)(dian)(dian)(dian)路便可(ke)實現(xian)此(ci)目(mu)的。

工作原理：如圖(tu)所(suo)示。V1為(wei)單結晶體管BT33C，它(ta)與R1、R2、R3和(he)(he)C1組(zu)成一(yi)個張(zhang)弛式振蕩器，SCR為(wei)單向可控硅(gui)，按下啟動按鈕AN1后，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，因為(wei)SCR無觸(chu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，所(suo)以(yi)不(bu)導通，繼電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器J不(bu)動作，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)通過R4和(he)(he)VD1給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)C2迅速(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)至接(jie)近電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)（Vcc-VD1壓(ya)降）。同時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)經(jing)R1給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)C1充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。數秒后，C1上(shang)(shang)(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)充(chong)(chong)到V1的觸(chu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，C1立(li)即(ji)通過V1放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，在R3上(shang)(shang)(shang)形成一(yi)個正(zheng)脈沖(chong)，該脈沖(chong)一(yi)路加到V2基極(ji)(ji)(ji)(ji)，使V2迅速(su)飽(bao)和(he)(he)導通，V2集電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)也即(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)C2正(zheng)極(ji)(ji)(ji)(ji)近于接(jie)地(di)。由于此時C2上(shang)(shang)(shang)充(chong)(chong)有上(shang)(shang)(shang)正(zheng)下負(fu)(fu)的正(zheng)極(ji)(ji)(ji)(ji)性電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，所(suo)以(yi)C2負(fu)(fu)極(ji)(ji)(ji)(ji)也即(ji)J線圈(quan)一(yi)端呈負(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)位。R3上(shang)(shang)(shang)的正(zheng)脈沖(chong)另(ling)(ling)一(yi)路經(jing)VD2、C3去觸(chu)發可控硅(gui)導通，SCR陰極(ji)(ji)(ji)(ji)也即(ji)J線圈(quan)另(ling)(ling)一(yi)端接(jie)近電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)。這時，J線圈(quan)實(shi)際上(shang)(shang)(shang)承受約兩倍的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，所(suo)以(yi)J1－1閉合，松開AN1后，J1－1自保(bao)。J1－2將V1、V2供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)切斷(duan)，繼電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器在接(jie)近電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)下工作。圖(tu)中，AN2為(wei)停止按鈕，按下AN2，J失(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)釋放(fang)，J1－1斷(duan)開，整(zheng)個控制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路失(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

制(zhi)作本電(dian)(dian)(dian)路時，一般可(ke)取(qu)繼電(dian)(dian)(dian)器的(de)(de)額定電(dian)(dian)(dian)壓(ya)為(wei)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)的(de)(de)1.5倍左右，一般情況(kuang)下，任何型號的(de)(de)單向(xiang)可(ke)控硅（或雙(shuang)向(xiang)可(ke)控硅）皆可(ke)滿足(zu)本電(dian)(dian)(dian)路需要(yao)。V2、C1、C3的(de)(de)耐(nai)壓(ya)視電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)的(de)(de)高低(di)選取(qu)。C2耐(nai)壓(ya)最(zui)好不低(di)于電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)的(de)(de)兩倍。

繼電器的三種附加電路

繼(ji)電(dian)(dian)器(qi)(qi)(qi)是電(dian)(dian)子電(dian)(dian)路(lu)中(zhong)常用的一種(zhong)元(yuan)件，一般由晶(jing)體管、繼(ji)電(dian)(dian)器(qi)(qi)(qi)等元(yuan)器(qi)(qi)(qi)件組成的電(dian)(dian)子開關(guan)驅(qu)動電(dian)(dian)路(lu)中(zhong)，往(wang)往(wang)還要(yao)加(jia)上一些(xie)附加(jia)電(dian)(dian)路(lu)以改變繼(ji)電(dian)(dian)器(qi)(qi)(qi)的工作特性或(huo)起(qi)保護作用。繼(ji)電(dian)(dian)器(qi)(qi)(qi)的附加(jia)電(dian)(dian)路(lu)主要(yao)有(you)如下三種(zhong)形式：

1.繼電(dian)(dian)(dian)(dian)器(qi)串(chuan)聯RC電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)：電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)形(xing)式(shi)如圖1，這種形(xing)式(shi)主要應用于(yu)繼電(dian)(dian)(dian)(dian)器(qi)的額(e)定工(gong)作電(dian)(dian)(dian)(dian)壓(ya)(ya)低于(yu)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)的電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)中(zhong)。當電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)閉(bi)合(he)時，繼電(dian)(dian)(dian)(dian)器(qi)線圈(quan)由于(yu)自感(gan)現象會產(chan)生(sheng)電(dian)(dian)(dian)(dian)動勢阻礙線圈(quan)中(zhong)電(dian)(dian)(dian)(dian)流(liu)的增大，從(cong)而(er)延長了(le)吸合(he)時間(jian)(jian)，串(chuan)聯上RC電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)后則可以縮短吸合(he)時間(jian)(jian)。原理是(shi)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)閉(bi)合(he)的瞬間(jian)(jian)，電(dian)(dian)(dian)(dian)容C兩端電(dian)(dian)(dian)(dian)壓(ya)(ya)不(bu)能突變可視(shi)為短路(lu)(lu)(lu)，這樣(yang)就將比(bi)繼電(dian)(dian)(dian)(dian)器(qi)線圈(quan)額(e)定工(gong)作電(dian)(dian)(dian)(dian)壓(ya)(ya)高的電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)加(jia)(jia)到線圈(quan)上，從(cong)而(er)加(jia)(jia)快了(le)線圈(quan)中(zhong)電(dian)(dian)(dian)(dian)流(liu)增大的速度，使繼電(dian)(dian)(dian)(dian)器(qi)迅速吸合(he)。電(dian)(dian)(dian)(dian)源穩定之后電(dian)(dian)(dian)(dian)容C不(bu)起(qi)作用，電(dian)(dian)(dian)(dian)阻R起(qi)限流(liu)作用。

2.繼(ji)電(dian)(dian)(dian)(dian)器(qi)并聯RC電(dian)(dian)(dian)(dian)路：電(dian)(dian)(dian)(dian)路形式(shi)見圖2，電(dian)(dian)(dian)(dian)路閉合后，當(dang)電(dian)(dian)(dian)(dian)流穩定時(shi)(shi)RC電(dian)(dian)(dian)(dian)路不起(qi)(qi)作(zuo)用(yong)，斷開電(dian)(dian)(dian)(dian)路時(shi)(shi)，繼(ji)電(dian)(dian)(dian)(dian)器(qi)線圈由于(yu)自感(gan)(gan)而產生感(gan)(gan)應電(dian)(dian)(dian)(dian)動勢，經RC電(dian)(dian)(dian)(dian)路放(fang)電(dian)(dian)(dian)(dian)，使線圈中電(dian)(dian)(dian)(dian)流衰減放(fang)慢，從而延長(chang)了繼(ji)電(dian)(dian)(dian)(dian)器(qi)銜鐵釋(shi)放(fang)時(shi)(shi)間，起(qi)(qi)到延時(shi)(shi)作(zuo)用(yong)。

3.繼(ji)電(dian)(dian)器(qi)(qi)并(bing)(bing)聯(lian)二(er)極(ji)(ji)管(guan)(guan)電(dian)(dian)路：電(dian)(dian)路形式見圖(tu)3，主要(yao)是為(wei)了保護(hu)晶(jing)(jing)體管(guan)(guan)等(deng)驅動(dong)元(yuan)器(qi)(qi)件(jian)。當圖(tu)中晶(jing)(jing)體管(guan)(guan)VT由導通(tong)變為(wei)截(jie)止時(shi)(shi)，流(liu)經繼(ji)電(dian)(dian)器(qi)(qi)線圈(quan)的(de)電(dian)(dian)流(liu)將(jiang)(jiang)迅(xun)速減小，這時(shi)(shi)線圈(quan)會產生很高(gao)的(de)自感電(dian)(dian)動(dong)勢與電(dian)(dian)源電(dian)(dian)壓疊(die)加(jia)后加(jia)在VT的(de)c、e兩極(ji)(ji)間，會使晶(jing)(jing)體管(guan)(guan)擊(ji)(ji)穿，并(bing)(bing)聯(lian)上二(er)極(ji)(ji)管(guan)(guan)后，即可(ke)將(jiang)(jiang)線圈(quan)的(de)自感電(dian)(dian)動(dong)勢鉗位于二(er)極(ji)(ji)管(guan)(guan)的(de)正向(xiang)導通(tong)電(dian)(dian)壓，此值硅管(guan)(guan)約(yue)0.7V，鍺管(guan)(guan)約(yue)0.2V，從而(er)避(bi)免(mian)擊(ji)(ji)穿晶(jing)(jing)體管(guan)(guan)等(deng)驅動(dong)元(yuan)器(qi)(qi)件(jian)。并(bing)(bing)聯(lian)二(er)極(ji)(ji)管(guan)(guan)時(shi)(shi)一定要(yao)注意二(er)極(ji)(ji)管(guan)(guan)的(de)極(ji)(ji)性不可(ke)接反，否則容易損壞晶(jing)(jing)體管(guan)(guan)等(deng)驅動(dong)元(yuan)器(qi)(qi)件(jian)。

無電感式模擬繼電器

圖中，220V電(dian)(dian)源經負載(zai)RL、R1、D1～D4、ZD1，為(wei)(wei)Q4、Q3在(zai)正負半周(zhou)輪流(liu)提供(gong)偏置；同時經R3、D5～D8為(wei)(wei)光(guang)電(dian)(dian)耦(ou)合(he)器(qi)Q1提供(gong)電(dian)(dian)源。當前級TTL電(dian)(dian)路輸出高電(dian)(dian)平信號時，光(guang)電(dian)(dian)耦(ou)合(he)器(qi)在(zai)市電(dian)(dian)正半周(zhou)內導(dao)(dao)通，于是在(zai)R5兩端產生(sheng)壓降(jiang)，觸發SCR導(dao)(dao)通，負載(zai)RL得(de)電(dian)(dian)工作。整個電(dian)(dian)路的功能(neng)如同一只(zhi)繼電(dian)(dian)器(qi)，但不(bu)會產生(sheng)反(fan)向感應電(dian)(dian)壓，也就避免了負載(zai)被高反(fan)壓擊穿(chuan)損壞的可能(neng)。C1、R6為(wei)(wei)脈(mo)沖吸收(shou)元(yuan)件，R3起限流(liu)作用。

為(wei)避(bi)免(mian)RL為(wei)感性負載時，可控硅(gui)的(de)電壓與光電耦合器(qi)電源(yuan)產生的(de)90°相(xiang)位，該(gai)電路中光電耦合器(qi)的(de)電源(yuan)取自SCR的(de)陽極而不直接取自市(shi)電電源(yuan)。

繼電器電路小改進

繼電(dian)(dian)器(qi)常(chang)安裝在電(dian)(dian)器(qi)設備的內部(bu)，其(qi)工作狀(zhuang)態不直觀，筆者將其(qi)作如(ru)下圖改進。在線(xian)圈(quan)(quan)兩(liang)端接發(fa)(fa)光二(er)極(ji)管(guan)VD1，當控制電(dian)(dian)壓為(wei)正時(shi)(shi)，三極(ji)管(guan)導通，繼電(dian)(dian)器(qi)J吸合(he)，同(tong)時(shi)(shi)發(fa)(fa)光二(er)極(ji)管(guan)被點亮(liang)，表明繼電(dian)(dian)器(qi)線(xian)圈(quan)(quan)已加上電(dian)(dian)源。發(fa)(fa)光二(er)極(ji)管(guan)可裝在外殼(ke)顯眼之處。

二、繼電器的正確使用方法

1、繼電器額定工作電壓的選擇

繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)額(e)(e)定(ding)工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)最主要的(de)(de)一項技(ji)術參數。在(zai)(zai)使用繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)時(shi)，應(ying)該首先考慮所(suo)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(即繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)線(xian)圈所(suo)在(zai)(zai)的(de)(de)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu))的(de)(de)工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)額(e)(e)定(ding)工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)應(ying)等于(yu)所(suo)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)。一般(ban)所(suo)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)額(e)(e)定(ding)工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)0.86。注意(yi)所(suo)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)工(gong)件電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)千萬不能(neng)超過繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)額(e)(e)定(ding)工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，否則繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)線(xian)圈容易燒毀(hui)。另外(wai)，有(you)些(xie)集成電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，例如(ru)NE555電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)是可(ke)以(yi)直接驅動繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)工(gong)作(zuo)的(de)(de)，而有(you)些(xie)集成電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，例如(ru)COMS電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)輸(shu)出電(dian)(dian)(dian)(dian)(dian)流(liu)小，需要加(jia)一級晶(jing)體管放大電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)方(fang)可(ke)驅動繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，這就應(ying)考慮晶(jing)體管輸(shu)出電(dian)(dian)(dian)(dian)(dian)流(liu)應(ying)大于(yu)繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)額(e)(e)定(ding)工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)流(liu)。

2、觸點負載的選擇

觸點負載是指觸點的承受能力。繼電器的(de)(de)觸(chu)(chu)點(dian)在轉換時(shi)可(ke)承受一(yi)定的(de)(de)電(dian)(dian)壓(ya)和電(dian)(dian)流。所以在使用(yong)繼(ji)電(dian)(dian)器(qi)時(shi)，應考慮(lv)加在觸(chu)(chu)點(dian)上(shang)的(de)(de)電(dian)(dian)壓(ya)和通(tong)過觸(chu)(chu)點(dian)的(de)(de)電(dian)(dian)流不(bu)能超(chao)過該繼(ji)電(dian)(dian)器(qi)的(de)(de)觸(chu)(chu)點(dian)負(fu)載(zai)能力(li)。例如，有一(yi)繼(ji)電(dian)(dian)器(qi)的(de)(de)觸(chu)(chu)點(dian)負(fu)載(zai)為(wei)28V(DC)×10A，表明該繼(ji)電(dian)(dian)器(qi)觸(chu)(chu)點(dian)只能工作(zuo)在直流電(dian)(dian)壓(ya)為(wei)28V的(de)(de)電(dian)(dian)路上(shang)，觸(chu)(chu)點(dian)電(dian)(dian)流為(wei)10A，超(chao)過28V或10A，會影響繼(ji)電(dian)(dian)器(qi)正常(chang)使用(yong)，甚至燒毀觸(chu)(chu)點(dian)。

3、繼電器線圈電源的選擇

這是(shi)指繼(ji)電(dian)(dian)(dian)器線圈(quan)(quan)使用的是(shi)直流(liu)電(dian)(dian)(dian)(DC)還是(shi)交流(liu)電(dian)(dian)(dian)(AC)。通常，初學(xue)者在進行(xing)電(dian)(dian)(dian)子(zi)制作活動中，都是(shi)采用電(dian)(dian)(dian)子(zi)線路，而電(dian)(dian)(dian)子(zi)線路往往采用直流(liu)電(dian)(dian)(dian)源供電(dian)(dian)(dian)，所以必(bi)須是(shi)采用線圈(quan)(quan)是(shi)直流(liu)電(dian)(dian)(dian)壓的繼(ji)電(dian)(dian)(dian)器。樂灌胃和(he)腹腔(qiang)注射實驗，結果(guo)(guo)發現(xian)可(ke)樂對(dui)小鼠(shu)精子(zi)活性和(he)形態(tai)有一定影響。但是(shi)截至(zhi)目前，仍(reng)無(wu)法(fa)證明飲(yin)用碳酸飲(yin)料對(dui)人體有“殺精”效果(guo)(guo)。
