查询词典 barrier

The I-V characteristics of the diodes with 100μm diameter indicated that as the densities of V-defects on GaN films increased from 4.1×105cm-2 to 1.03×107cm-2, the Schottky barrier height decreased from 1.44eV to 1.19eV and the reverse bias leakage current at -1V is increased sharply from 10-10A to 10-7A . Further studies on a single V-defect using conductive atomic force microscope demonstrated that the value of forward current biased at 8V at V-defect side-walls appears to be one order higher than that of plain region, indicating that the conductivity mainly occurred at the side-walls of V-defect.

实验结果发现，随著V型缺陷密度由4.1×105cm-2增加至1.03×107cm-2，在氮化镓表面蒸镀镍金属所制成直径为100μm的萧基元件之所属能障从1.44eV下降至1.19eV，而且在-1V的操作下反向偏压漏电流从10-10A急遽的攀升至10-7A；为了了解V型缺陷对厘米尺寸n-GaN萧基元件电流传导机制之影响，我们进一步的利用导电原子力显微镜(Conductive Atomic Force Microscopy， C-AFM)，特别针对单一个V型缺陷进行微观电性之量测。

The rapport with Francesco is excellent, even if we have trouble communicating because of the language barrier.

我和托蒂的关系很好，即使我们因为语言障碍在交流上有些困难。

These phenomena occurred due to the increased free volume and chain mobility of polymers, and the decreased energy barrier for crystal form transition by the plasticization effect of scCO2 and other supercritical fluids.

这些现象的发生，是由于超临界二氧化碳及其它超临界流体增大了聚合物的自由体积和链活动性，降低了相转变的能垒。

Objective: In order to investigate whether the recombinant adeno-associated virus -mediated foreign genes, LacZ/hVEGF, could pass the blood brain barrier by intra-carotid artery delivery or not and to investigate whether the foreign genes could be expressed in vivo in ischemic brain of the focal embolic stroke rats or not, a high titer and completely adenovirus free recombinant adeno-associated virus vector was constructed and studied.

目的：为了检测腺相关病毒载体携带的人类血管内皮因子基因能否通过血脑屏障及能否在脑组织中表达其基因产物，我们构建了一种新型、高滴度、无腺病毒污染的rAAV携带的报告基因和hVEGF基因分别经颈动脉对自体血栓局部脑卒中大鼠进行了研究。

Part of me even misses the frisson of cold stares from the border guards, brusque orders to open the car boot and the delicious relief when the ink-stamp came down on passport paper and the red-striped barrier was finally lifted (although it was rather less fun for citizens of communist countries).

我还无法忘记边境卫兵那使人战栗的冰冷目光，无法忘记他们命令我行驶汽车，无法忘记护照上敲章、红色条纹的障碍打开时如释重负（尽管这对于共产主义国家的人民来说并不是一件有趣的事）。
