反向压力

Under the same pressure gradient, the seepage velocity of leaching solution well increases with the intensity of positive electric field, and decreases with the negative electric field. The seepage diffusibility of leaching solution and its wetting ability to fractured rock mass can be enhanced or weakened by the electric field.

在同等压力梯度下，受地电场作用的裂隙岩块中溶浸液渗流速度随正向电场强度增加明显增大，随反向电场强度增加明显减小；地电场能够强化或者减弱裂隙岩块中溶浸液的渗流扩散能力和溶浸液对岩块的润湿作用。

Therefore, it is of great significance for building up a harmonic society to present housing reverse mortgage loan to public.

Nevertheless Kees van den Ende, the reverse-electrodialysis project manager at KEMA, thinks his process has some advantages over the Norwegian way (which is known, technically, as pressure-retarded osmosis).

但是KEMA公司反向电渗析项目的负责人基斯·范登·恩德认为他们的方法相对于挪威的方法（用科学术语来说，叫作&压力延迟渗透&）来说有几个优点。

This paper introduces pressure pipe TIG welding(Argon tungsten -arc welding),and resolves successfully the problem that the faults easily occur on the back of the head in the weldi ng by using the method of reversed wir e feeding.

介绍了压力管道 TIG焊，用反向送丝的方法成功地解决了焊接中焊道背部易出现缺陷的问题。

Several different types of valves are in use.

有几种不同的阀在使用中，有些是反向压力阀。

For wire bonding,we got methods to avoid low-k material layer crack and IMC crack by gold wire selection,capillary design optimization,and wire bonding process window study;Wire sweep issue was declined,after use reverse wire bonding technology to get low wire loop,define high wire loop and low wire loop between neighbour wires to reduce wire cross and split transfer course into several segments by different transfer speed to control mold flow;For molding and to different packages,as a physical method,add suitable presser during different cure process,it can reduce warpage value;As chemical methods,optimized component of molding compound or added flexiblier,it can decline thermal stress and warpage.

在引线键合方面，通过对不同纯度金线的选择、劈刀设计的优化、以及对引线压焊工艺窗口的研究，找到了可降低焊盘碎裂，金铝间化合物分层等问题的方法；通过使用反向压焊来控制线线弧高度和在邻近线间使用高(来源：A7aB4848C论文网www.abclunwen.com)低线弧来控制线弧以及模塑注塑速度细分化的方法，有效降低了冲线值；在模塑方面，针对不同封装形式，通过封装模块在烘烤过程中优化外加压力的时机，利用物理方法有效减低了翘曲；此外从化学角度出发，通过对模塑材料配方的优化以及添加应力释放剂，有效降低了封装内的热应力，减小了封装模块的翘曲。

The question of ruined earth pressure cell in test is solved,and the contact pressure between soil and pile is found out by the numerical simulation and distributing law of earth pressure.

通过数值模拟，解决试验中土压力盒损坏的问题，得到地震动激励下桩–土接触压力峰值的数据，并由此分析桩–土接触压力的大小及其分布规律，提出桩基上的支盘是基础减振的主要构件，并承受动荷载，减轻地震波对上部结构的冲击力，同时消耗上部结构反馈给基础的振动能量。承台和桩基两侧的土压力时程曲线呈反向关系，说明基础在同一时间一侧受压，另一侧受拉。

With the valve blocked, the buildup of pressure causes the thrust reversers to deploy.

随着阀门阻塞，积聚的压力导致推力反向器部署。
