实例计算表明，提供的模型和方法及研制的软件既可用于预测油田压裂前后的生产动态和压裂后的增产效果，又可用于压裂井水力压裂方案的优化设计。

After analyzing and processing the grating reticle image collected by CCD, the mapping coefficient can be accurately calculated from grid size to pixels. Comparing the fore-and-aft two grating reticle images after the worktable moved. Adopting phase difference ratio arithmetic based on Lissajous figures,the phase difference of two images will be figured out. The displacement of the worktable can be further calculated by the mapping coefficient.

调整光路使CCD获取清晰的光栅图像，对图像进行分析处理，计算出栅距与像素之间的映射关系，再对工作台移动前后的光栅图像进行对比，采用基于李萨如图的相位差比率算法获取它们的像素位置差，从而计算出工作台的实际运行位移。

ABSTRACT Based on theoretical analysis of axial compression of ring-shape specimen between two flat dies by an upper-bound technique,it is possible to carry out the measurement of both the friction coefficient of lubricant and the basic flow stress of the ring material under particular temperature and strain rate.

摘 要 根据圆环压缩的连续速度场上限定理的理论分析，通过圆环试样压缩前后的几何尺寸的变化，能测量润滑剂的摩擦因数和圆环材料的流变应力。

That last little bit of "depth" was missing.

打个比方的话，这是一幅聚焦很清晰的图画，可以看到前后的层次，每件东西的位置，但所有的东西都象是纸板剪出来的，缺少了一点点深度感。

In this paper, the principle, the basic structure and the workflow of this system are analyzed. Aiming at the Snort system working in a single thread, a reform scheme based on the multithreading technique for developing its performance is put forward, including a queue between two function modules and a busy sign flag in every decoder and chain node. The workflow of the reformed system is described then.

为提高Snort系统的性能，针对其工作流程是单线程的特征，用处理模块间设置缓冲队列、各个协议解码器和链表节点设置忙闲标识等方法实现了对其的多线程改造，并详细描述了改造后系统的工作流程，最后结合简化模型模拟实验结果，分析了改造前后的系统各性能的变化。

Cooling-curves of different composition after ultrasonic blend were measured with the guide of theory forecast results of the binary system of capric acid and myristic acid. The experiment phase diagram was protracted, eutectic temperature and composition range were discovered of the binary system. Phase change properties of eutectic composition were tested with DSC, the change of the wave shape of eutectic composition after 300 thermocycling was tested with IR.

以癸酸-十四烷酸二元体系的理论预测相图为指导，测量了该体系不同组成超声波混合后的步冷曲线，绘制了该体系的实验相图，判断出最低共熔温度与组成范围；采用DSC测试最低共熔组成的相变性能，采用IR检测最低共熔组成300次热循环前后的波形变化。

At last, on the base of previous summing up, we need to centralize to study changes about essence of man and cognitive fashion of man before and behind post-modernism.

最后，在前文总结的基础上，需要集中考察后现代前后的"人的本质"、人的认知方式观念的流变。

An optimum threshold level is found that minimizes distortion of the power spectrum for speckle data of the circular and ring apertures.

针对具体的圆形和环形散射屏引入的散斑图样，采取使处理前后的功率谱偏差最小的方法，找出了最佳的阈值。

If, however, to figure out the financial crisis in the U.S. and around the clock to run down the track, in fact, relations with China, because in the U.S. financial tree of tree root system, there is no correlation with the Chinese a few, China against the United States investment in the financial sector, up to a "rattan wrapped around the tree" instead of "root root bound."

但是，如果搞清楚美国这次金融危机的脉落和前后的运行轨迹，其实和中国的关系并不大，因为在美国这棵金融大树的根系里，没有几根与中国相关，中国对美国金融领域的投资，至多是"藤缠树"而不是"根缠根"。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
