查询词典 junction transistor

The histopathologic observations of corneas after penetrating keratoplasty in dogs: Thestructure of wholly transparent graft was the same as that of host cornea apart from the upperdonor-host junction where there was minimal irregularity of the corneal lamellae. However, thecorneal lamellae at the lower donor-host junction were neat. The graft with its central part beingtransparent only showed poor coaptation with recipient, in which the graft shifted inward and had marked wrinkles and folds in Descemet"s membrane. On the back of Descemet"s membranethere was hyperplastic stromal fibers that thickened the graft and partially adhered to iris.

5犬穿透性角膜移植术后角膜病理组织学观察完全透明的植片与植床结构一致，仅两者对合处上部纤维紊乱，而下方纤维排列整齐；中央透明的植片与植床对合不良，植片向植床方向嵌入，后弹力层皱缩、折叠，植片下方因有来自植床的基质纤维而增厚，部分对合处与虹膜粘连；浑浊的植片有比较完整的上皮层，植片约2／3深度的基质丧失原来纤维整齐排列结构，代以大量成纤维细胞增生。

A term applied to (1) the junction of skull and ear lobe and (2) the junction of tail butt and rump.

头颅和耳朵突出地方的连接处，2）尾根和屁股的连接处

Through calculating it is discovered that there is elastic strain energy concentration near triple junction when loading direction is parallel with triple junction, but the concentration degree is not so high.

因为应变能中包含了所有的应力分量和应变分量，能全面地反映各应力分量对三晶交点应力集中程度的影响。

Normal working hours, B2-B1 between the need to add a positive voltage, E-B1 between the PN junction forward biased if the Canadian single-junction transistors that turn, after turn-on, E-B1 between the resistance will soon be reduced, to B2-B1 between the current rapid increase in current increase, so that the resistance between the E-B1 further reduced, so the formation of a strong positive feedback.

正常工作时，B2—B1间需加正电压，E—B1间的 PN结若加正向偏置，单结晶体管即导通，导通后，E—B1间的电阻会很快降低，使B2—B1间的电流迅速增加，电流的增加，又使E—B1间的电阻更进一步的减小，如此形成了强烈的正反馈。

B-e and b-c junctions will measure like a diode with the b-c junction reading slightly lower than the b-e junction when forward biased.

发射结和集电结跟二极管差不多，集电结正向偏置时的读数要稍小于发射结。

In addition, in comparing of the junction temperature and the light-emitting diode spectrum, we see the junction temperature has certain effect to the decay of the light output power of light-emitting diodes.

另外，在接面温度与发光二极体光谱的比较方面，我们也从实验上知道接面温度在发光二极体的光输出衰减方面有一定的影响。

Measurements of BE and BC junction diode properties at different temperatures have indicated that the rapid growth of BC junction leakage current with temperature is the cause of HBT degradation.

通过测量BE结和BC结在各温度的二极管特性，发现高温下BC结漏电流急剧上升，导致HBT性能退化。

The n-type gate modulation could be explained by the bending effect of valence band in the Schottky-barrier junction. The photoconductive diode and optical switch behavior was demonstrated for the first time from a C/CNX multi-walled nanotube junction with a Schottky barrier. Theconductivity of nanotube can be reversibly changed by 3 to 4 orders of magnitude when the 5 mW cm2 white lights was turned on and off.

器件原理是栅极静电场调节碳纳米管和CNx纳米管间的Schottky势垒的高度和宽度，从而影响载流子的传输。8首次利用单根CN万／C纳米管作为半导体材料制备了Schottky光导二极管和光开关。

Using the mechanism, we also fabricated large-area silicon nanowire p-n junction diode arrays by chemical etching of planar silicon p-n junction wafers in aqueous HF solution containing appropriate silver nitrate near room temperature.

进一步研究了硅衬底在HF-MoxMox=KAuCl4、K2PtCl6、Cu(NO32、Ni(NO3)2、Mg(NO3)2等氧化剂混合水溶液里的腐蚀行为，并提出了一种新的硅纳米线形成机制－金属枝晶辅助纳米电化学机制。

Methods 30 adult cadavers were dissected by regional anatomy through manubrium sterni and medial 1/3 clavicle resection,simulating anterior approach to the cervicothoracic junction of the spinal column,some important structures anterior to the body of the cervicothoracic junction of the spinal column were analysed and measured.

方法供局解教学操作使用的成人尸体30具(男25、女5)，模拟经胸骨柄和部分锁骨切除的颈胸段脊柱前路术式，采用连续层次解剖方法，重点观测手术途径中暴露C5~T3椎体时必须牵开并加以保护的几个重要结构。

Warden: That's a beautiful dog, but don't bring her again.

那是条漂亮的狗，但是不要再把她带来了。

You get up in the morning – no hangover!

你第二天早上起来的时候—不会宿醉！
