查询词典 problem of contact

The real borehole axis is not an ideal straight line, but a helical line with arbitrary curvature, so the contact problem between the down-hole string and the borehole face is a kind of arbitrary contact nonlinear mechanics problem, which can not be solved by the common methods from material mechanics and structural mechanics.

At last a numerical iteration scheme is used to solve for the load of asperities, the real area of contact for each asperity, the size of the contact spots and the average contact pressure with given conditions.

通过数值模拟，得到了给定条件下各个微凸体上的载荷、真实接触面积、接触斑点尺寸和平均接触压力的分布情况。

The simulation of contact properties (contact stress and contact deformation ) of the asperities is realized using ANSYS. Further, the wear simulation model is validated by the results of pin-on-disc testing.

表面微凸体的接触特性仿真采用ANSYS实现，磨损仿真模型通过销盘试验结果给予了验证。

By using Transmission Line Model to investigate the ohmic contact of electrode metal and InP semiconductor. We got a low specific contact resistively of 2.24×10-5 Ω-cm2 of the AuBe/Cr/Au contact to p-InP.

我们用Transmission Line Model方式得到低的特徵接触电阻约2.24×10-5 Ω-cm2之AuBe/Cr/Au属和p-InP形成的欧姆接触。

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。

The contact curved surface equations and the contact plane surface equations have been worked out. The boundary curve eqations of the contact surface have been founded.
