您要查找的是不是：
- The average dark current is often eliminated by means of a zeroing circuit. 平均暗電流常利用調零電路消除。
- The thermally generated dark current intrinsic to the photodiodes is always working to charge the diode. 光電二極管固有的熱產(chǎn)生的暗電流不斷為二極管充電。
- Hence, due to the low noise gain and low dark current, the maximum detectivity (D*) can occur at low negative bias. 因此，由于暗電流與雜訊增益都降低，最大值的偵測度可以在負低偏壓時(shí)出現。
- Why is it that all the fast-moving fish of the dark current have purple backs and usually purple stripes or spots? 怎么搞的，凡是在深暗的水流中游得很快的魚(yú)都有紫色的背脊，一般還有紫色條紋或斑點(diǎn)？
- We find that the photocurrent of this device is not reduced by the additional MQWs but the dark current is. 我們發(fā)現超晶格所產(chǎn)生的光電流并沒(méi)有因為量子井結構而降低，但暗電流卻有減少。
- If the photodiodes have large amounts of dark current, much of the diode's signal capacity will be filled up by charge with no signal information. 如果光電二極管有大量的暗電流，大部分二極管信號電容會(huì )在沒(méi)有信號情況下被充滿(mǎn)。
- Etching the surface of germanium layer could decrease the dark current and increase the responsivity under the visible light exposure. 當蝕刻鍺層的表面時(shí)，我們可以得到較低的暗電流并且提升可見(jiàn)光下的光響應。
- This type of amorphous-silicon photodiode has the advantages of low dark current and a capacitance that is independent of the accumulated signal. 這種非晶硅光電二極管有很多優(yōu)勢，如低暗電流和能獨立積累信號的電容。
- At the same time we studied the difference for use LED low intensity light source and dark current method, mea sured photoelectron spectrum. 同時(shí)也介紹了用LED光源測得的單光電子幅度譜及用熱發(fā)射法測得的暗電流譜的差異,并分析了兩種方法測得的幅度譜的差異的主要根源。
- Finally, we advanced an assumption to explain that thick active region had lower dark current and used the program to simulate the experiment result. 最后我們提出一套理論解釋較厚的主動(dòng)層具有較低的暗電流，并利用程式來(lái)模擬實(shí)驗結果。
- Abstract： In all optical asynchronous CDMA communication system，multi-user interference and PIN dark current noise can be reduced by introducing double optical harder-limiters. 摘 要： 在全光異步CDMA通信系統中，引入兩個(gè)光硬件限幅器是有效減小多用戶(hù)干擾及PIN光電檢測過(guò)程暗電流噪聲的一種方案。

- I groped for the light switch in the dark room. 我在黑暗的房間里摸索著(zhù)找電燈開(kāi)關(guān)。
- We started early in order to arrive before dark. 為了在天黑前到達，我們很早就動(dòng)身了。
- The thick blocking barrier will not only reduce the dark current but also the responsivity and photocurrent.Therefore, the detectivity for the thick barrier SLIP is at the same order for the thin one. 除此之外，厚的電流能障，不僅會(huì )使得暗電流降低，同時(shí)也會(huì )降低光電流與光響應的大小，因此厚能障與薄能障偵測器的偵檢率皆在同一個(gè)倍率。
- On the other hand, the effect of finger spacing on the photocurrent is more significant.When the finger spacing increases, the photocurrent decreases and the dark current is almost changeless. 指間距增大時(shí)光電流減小而暗電流幾乎不變，而且指間距對光電流的影響比對暗電流的影響大。
- The simulation results indicate that the dark current and the photocurrent both increase when the finger width increases.But the effect of finger width on the dark current is more significant. 模擬結果表明，指寬增大時(shí)探測器的暗電流和光電流都增大，但指寬對暗電流的影響比對光電流的影響大；
- In practice，other noise in the system can be reduced by introducing double optical harder-limiters also，such as：APD shot noise，APD dark current noise，background light and thermal noise. 實(shí)際上，引入兩個(gè)光硬件限幅器同樣可以減小系統中的其他噪聲：APD光電檢測過(guò)程中的散粒噪聲、暗電流噪聲、背景光影響、消光比影響及熱噪聲。
- An absence of improvement in the dark current was observed.However we did observe an improvement in the material quality (low ideality factor 1.75 and series resistance 0.3k ) for forward bias. 逆偏壓下暗電流沒(méi)有改善，但在順偏壓下，觀(guān)察到材料品質(zhì)的改善（低的理想因子值約1.;75與串聯(lián)電阻300歐姆）。
- Her sublimate future husband will be tall, dark, and handsome. 她理想化的未來(lái)丈夫將是身材高大，皮膚淺黑，相貌英俊。
