Abstract : the rechargeble batteries are used for backup power internal electrically equipments and instruments . but batteries lifetime usually is shorten by overwork and then malfunctions of equipment are induced . to avoid the complexion described above , the protection circuit against overwork is designed . it is based upon the voltage comparator and regulator . it will light up a red led when the volume of the batteries discharged close upon 50 % ; it will switch off the load automatically when it discharged closing to 80 % of their energy capacity , thus overwork of batteries can be avoided and lifetime may be extended 文摘:用蓄電池做后備電源的系統(或設備) ,常因過放電導致電池提前報廢而造成設備故障.根據電池電壓隨容量變化的規律,利用電壓比較器和電壓基準源設計制作了電池放電保護電路,當電池放電量接近容量的50 %時,啟動預警信號;當電池放電量達到容量的80 %時,電路自動切斷負載,防止電池過度放電,延長電池壽命,保證系統(或設備)在供電恢復正常后能正常運行

During the formation , the positive plates with red lead and bapbo3 additives are easier formed than that without additive , so the current and potential distributions on the plates with additives are more uniform than that without additives in the early stage of the formation . these distributions on the plate with red lead are the most uniform , and the polarization is the smallest 在正極板化成過程中,含紅丹和鉛酸鋇鉛膏的正極板比不含添加劑的正極板更容易化成,所以在化成初期含添加劑正極板的電流密度和電位分布比不含添加劑正極板上的電流密度和電位分布更均勻。

Remember the following words and expressions : e . g . multimeter ; circuit , current ; voltage ; resistance ; digital multimeter ; analogue multimeter ; analogue multimeter scales ; zero adjustment control ; zero adjustment control for resistance ranges ; measurement ranges switch ; transistor test socket ; meter probe ; positive terminal ; negative terminal ; anode ; cathode ; red lead ; black lead ; power supply ; connect in parallel ; connect in series 記住萬用表、電路、電流、電壓、電阻、數字萬用表、模擬萬用表、表頭、機械零位調整器、歐姆零位調整器、量程選擇開關、晶體管插孔、表棒、正接線端、負接線端、陽極、陰極、紅導線、黑導線、電源、并聯、串聯等常用英文單詞,并逐步掌握。

Thus , such phenomena as vermilion turning black , aging of red lead and the fading of arsenic can now be more essentially represented by the chemical reactions of cinnabar having its crystal lattice transformed , lead tetroxide turned into lead dioxide , and arsenic sulfide turned into arsenic oxide 于是,朱砂變黑,鉛丹老化,石黃退色等現象,便可以用硫化汞轉變了晶格,四氧化三鉛變成了二氧化鉛,硫化砷變成了氧化砷來更本質地加以表述了。

When it is discharged at high - rate , the distributions are also the most uniform at the end of the discharge . this indicates that the positive plate with the red lead has the better discharge performance than the other two kinds of positive plates 含紅丹的正極板在化成初期電流密度和電位的分布最均勻,極化最小,在高倍率放電結束時,其電流密度和電位分布也最均勻,表明含紅丹的正極板的放電性能比其它兩種正極板好。

Seryozhka in himself is a nonentity , a sluggard , a drunkard , and a wastrel , but when he has his red lead or compasses in his hand he is at once something higher , a servant of god 謝遼日卡本人是個微不足道的人,懶漢,酒鬼,手里一有錢就花光,然而一旦他手里拿著鉛丹或者兩腳規,他就成了個高尚的人物,上帝的仆人了。

And questions have been raised about other products , including children ' s toys covered in red lead paint 對于其它產品,包括刷有含鉛涂料的兒童玩具,人們也不禁產生信任危機。

Calibration marker : simple installation , minimizing direct reflection infrared or visible red led types 校準標記:安裝簡易,可最小化直接反射紅外線或可見紅色led類型

Red led flash to indicate the load exceed the current limit and the protecting function start 紅燈閃爍,表示過負載,使用電流超過額定設定,主機保護機制開啟。

Do not mix up the yellow and red leads , as this will cause the memory contents to be lost 不要混淆黃色和紅色導線,這將引起內存內容丟失。
