查询词典 barrier

Based on this analysis, we then made a teaching assumption to get rid of such kind of thinking barrier, ie."Symbolizing the propositions in everyday life and finding dual proposition according to symbolic rule will enhance students' understanding of the argument principle of proof by contradiction."

进一步提出克服此种思维限制以发展逻辑思维的教学假设─「将生活情境中命题的真伪关系符号化，利用符号规则推理再转译回生活命题，可增进学生对反证法论证原理的了解」，并据以发展教案进行探究性教学。

The use of distance emphasises the artificiality of artistic creation, the insurmountable barrier that separates art from life.

距离感的运用恰到好处的突出了人工设计和创作的心思，这也是现实生活和艺术之间不可逾越的屏障分隔。

"Countrol area" should be surrounded by a barrier and sentry boxes at regular intervals, manned by armed police guards. Persons engaged in the management and maintenance of the nuclear material and facility must carry an identity card containing a photograph. Visitors accompanied by assigner must present a visitor's pass and register in order to be admitted.

一管制区：外围以不易攀越之密集铁剌网或顶端加装密集铁剌网之围墙围绕，置岗哨，并设置专业警察看守，仅许管制及工作人员配带附有照片之识别证，或访客经批准由专人陪同，凭参观证并经登记后始得进出之区域。

The blood-brain barrier consists of capillary endothelial cells,basement membranes and astrocyte foot processes.

血脑屏障是由血管内皮细胞、基膜和星形胶质细胞血管终足构成的。

During early pregnancy, the endometrial cells can form atemporal permeability barrier around the embryo to protect it from the maternal harmfulenvironment.

在妊娠早期过程中，为了保护胚胎免受母体不利环境的侵害，子宫内膜细胞在胚胎的周围形成了一个短暂的渗透屏障。

The third approach is about the concept of an ITO direct Ohmic contact structure on GaP window layer. The direct Ohmic contact structure is performed by the deposition of an AuBe diffused thin layer and the following activation process on the surface of a Mg-doped GaP window layer. The presence of this thin AuBe diffused layer yields the Be dominant metallic surface layer and significantly reduces the barrier height between the ITO and p-GaP layer. Via the modification of contact structure, not only the brightness was significantly increased but the reliability was comparable to the conventional LED without this structure.

第三个研究为一种具有直接欧姆接触在p型磷化镓窗层与氧化铟锡界面的制程方法，於本研究中并无习知砷化镓欧姆接触层的存在，我们利用金/金铍金属藉由热退火程序，使其金铍原子在磷化镓窗层表面形成具金属特性之薄膜层，降低磷化镓与氧化铟锡接触产生之接面能障；另外，该元件在氧化铟锡直接欧姆接触於磷化镓窗层下，除亮度具明显提升外，在稍大电流(20毫安培)元件可靠度测试下，亦未有明显衰减情形发生。
