The approximate solution shows that there is a rectilinearity in the pressure and time semilogarithmic coordinates.

注水井压降试井的近似解表明在压力与时间的半对数坐标下呈直线关系，直线的斜率与截距取决于注采比、注采井距、注采厚度比、注采产能系数比等参数。

The results showed that the determined components are homogenous on different position of sample surface and in different depth of the sample, and the repeatablity of determination resuts was also good under same preparation conditions. So this way could surmount the error from the sample preparation of powder press.

试验结果表明，块状样品表面不同部位及不同深度的化学成分分布均匀，相同熔融条件下的样品重复性良好，解决了用粉末压片制样对测定结果带来的误差。

Under the condition of pure thermal load, enlargement of particle size and lengthdiameter ratio and particle cluster will increase the serious plastic thermal residual strain concentration in the matrix near the pointed particle corner and the serious compressive thermal residual stress concentration in the pointed particle corner.

发现在纯热载荷作用下，颗粒尺寸加大、长径比加大及颗粒的团聚会使颗粒尖角附近基体的塑性热残余应变集中和颗粒尖角上严重的残余压应力集中加剧。

The ΔG about the reacting process has been calculated according to the reversible process .

设计了理想混合气体在等温等压条件下的可逆化学反应过程。

High-strength rock wool board: used for various high/low temperature conditions, with good weight-bearing ability and compression-resistance, specially suitable for heat preservation and heat insulation for large ships, tanks, ovens, pipelines and other industrial facilities.

高强度岩棉板：适用于高、低温的各种条件下，有着很好的承载、抗压特性，尤其适用于大型船舶、容器、烘箱和管道及工业设备的保温、绝热。

Researched results indicated that contact force's modification was very little inner joints of synchronize Mechanism under the state of no-load and heavy load of sizing press, the rolling force that slab deformed created was supported mostly by side Mechanism.

研究结果表明，调宽机在空载和工作两种状态下，同步机构各构件间的运动副内接触力变化不大，侧压机构主要承受了板坯变形产生的轧制力。

Thus, the spherical-crown and saddle-shaped surfaces were demonstrated. Consequently, the basic rules and key technology of bending forming using plasma arc in practical work were obtained and the application level of the flexible forming using plasma arc had been further improved. The effects of the main parameters including power, scanning speed, scanning distance and scanning sequence had been investigated.

对成形中出现的棱角效应进行了机理分析和数值计算，结果表明棱角效应是板材沿扫描线方向受几何约束产生了较小的压应变及在扫描线上、下表面的收缩量不同所造成；提出了通过分段扫描解决棱角效应的方法，明显提高了成形质量。

Safety valve is designed for emergency safety relief and shall not be used as an operating control.

安全阀用于危机状态下的安全泄压，不应该作为操作控制的工具。

His weight sagged heavily against her, and all at once it was a corpse that she embraced, there in the black rain.

他的重量压在她身上，死沉死沉，下一秒钟，她环抱着一具尸体，站在黑色的雨中。

A sahib has got to act like a sahib; he has got to appear resolute, to know his own mind and do definite things.

事已至此，既有步枪在握，又有两千多人给我压住阵脚，我却当众下个软蛋，什么也不干吗？

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
