It is indicated that this loss will not change with the increase of the Reynolds number but the intensity of the passage vortex increases with the decrease of the Reynolds number. The tip leakage flow will weaken with the increase of the passage vortex because of the interaction between the passage vortex and the tip leakage vortex, and the position of the tip leakage vortex is more close to the middle of the passage. In addition, the distributions of the total pressure loss and the flow angle at the exit of the cascade are influenced by the intensity and the position of the tip leakage vortex.

结果表明：对于间隙存在造成的流动损失，数值模拟结果与实验结果及 Denton的预测值都十分接近，基本上不随着雷诺数的变化而变化；但是，随着雷诺数的减小，通道涡增强；间隙泄漏涡在和通道涡的相互作用中，强度减弱，在叶栅出口处的位置更加靠近中叶展；出口处的总压损失和气流角的分布也由于间隙泄漏涡强度和位置的变化而发生改变。

Passage width influences stress of the middle part of passage significantly, displaying linear relationship.

利用三维有限差分程序对过江双线盾构隧道横向疏散通道进行力学特性分析，考虑围岩、水压及隧道衬砌相互作用，选取覆土最浅且水压最大时工况建立了计算模型，利用该计算模型分析了不同横通道宽度和两主隧道差异沉降对结构的受力影响规律。

From dead-end to open-end, surface velocity increases gradually if the filter passage is shorter and surface velocity of both ends is large than that of middle section if the filter passage is longer. Compared with cylindrical filter, the distribution of surface velocity of conical filter is more uniform.

当过滤通道较短时，过滤元件表面速度沿过滤元件轴向逐渐增大；当过滤通道较长时，过滤元件两端的过滤速度比过滤元件中部的大；同圆柱形过滤元件相比，锥形过滤元件过滤速度的分布更为均匀。

In order to shorten the acquisition time of multichannel combined acquisition, a new parallel acquisition algorithm is proposed.

为了缩短多通道直接序列扩频信号的捕获时间，提出了一种新的多通道并行捕获算法。

It allows users to change or lock the channel topic through the use of public commands in the channel, with fine-grain permission controls available.

它允许用户使用通道中的公共命令来改变或锁定通道主题，同时可以对权限进行一些控制。

So that the channel immediately exit valve seat to prevent the rapid expansion of body wall and the wall suffered cavitation damage, and for Water in the needle valve, the expansion chamber diameter of 1.5 times the diameter of including pull back the export channel, including length of 8 times the diameter when subjected to cavitation can be avoided.

使紧接阀座出口端的通道急剧扩大可防止阀体壁和管壁遭受气蚀损坏，对用于水厂中的针形阀，其扩大腔室的直径为管径的1.5倍，包括出口退拔在内的通道长度为管径的8倍时，可避免遭受气蚀。

Microchannel Plate is a type of electron multiplier.

微通道板(Micro-channel plates MCP)是一种微通道电子倍增器。

By comparing the electron gain of the prepared silicon microchannel plate with conventional one,we found the electron gain of Si MCP was larger than glass MCP.Though there were some problems to be solved in the manufacture of electron multiplier of Si MCP,it was expected that Si MCP would be a new approach to enhance the performances of MCP and the quality of image devices.
