Ultrasonic measurement method is a new one. It has many advantages, such as, not changing the profile of the flow and characters of the fluid, non-invasion, no pressure losing and can work under the severe conditions. Collecting the flow noise signals at the upstream and downstream of the pipe, adopting the cross correlation method to analysis signals, calculating the cross correlation function and finding the peak of it, then we can get the transit time.

超声波流量测量具有不改变流动状态与性质、非接触、耐恶劣环境等优点，通过对所采集的上、下游流动噪声信号进行相关分析，其互相关函数的峰值位置所对应的时间，为流体流过上、下游传感器之间的距离所用时间，进而计算出流速和流量。

COV gathers can also be constructed through selecting traces from different cross spreads of a 3D survey. A simple and practical way of constructing COV gathers can he described as that 1 when a dominant receiver line direction is determined, the inline offset and crossline offset of every trace can be calculated; 2 the inline offset and crossline offset ranges fruit; negative to positive for the whole dataset can be well represented by the range of the receiver spread of a typical source; 3 the full range of inline offsets can be divided into several sob ranges using twice the source line spacing and the full range of crossline offsets can be divided using twice the receiver line spacing; and 4 one sod; sob-range inline offset and one such sob-range crossline offsets form a COV gather.

一个简便实用的构造COV道集的方法是：在给定检波线的走向后，计算出每一地震道的inline炮检距和crossline炮检距；用观测系统中一个具有代表性的炮点的检波器排列范围来确定整个数据的inline炮检距范围和crossline炮检距范围，用两倍的炮线间距把inline炮检距的范围分成若干份，用两倍的检波线间距将crossline炮检距的范围也分成若干份，一份inline炮检距和一份crossline炮检距就构成一个炮检距向量道集。

A theoretical model for calculating the cutting angle with different crystal planes, orientations and tool orthogonal rakes are described in this paper. It is built with the ultra-precision cutting model by the principle of the maximum specific energy of shear deformation and the mechanism of change of the shear modulus with...

本文利用剪切变形比能最大及单晶材料不同晶面晶向剪切弹性模量不同的原理，结合超精密切削模型，从理论上计算出不同晶面、不同晶向及不同刀具前角超精密切削条件下的剪切角，得到其在不同切削条件下的变化规律，并由此解释了切削加工中由KDP晶体各向异性所导致的工件表面粗糙度的各向异性。

In practice the diffraction pattern is iteratively solved at ever-increasing "shells" of resolution; the crystallographer alternates between building a model structure （working in "real" space） and comparing the model's calculated diffraction pattern with the observed diffraction pattern （working in "reciprocal" space）.

The observational and calculated results are well matched. The calculated mean diameter, mean square-root diameter, mean cube -root diameter and liquid water content are all well matched with the observational results; In the paper two examples have been analyzed by using the seeding region data and the possible affecting region data in leeward region. It is found that F-100, 2dc, and 2dp's particle concentrations increase in leeward region, but rising extent is different, which is likely to be due to difference of seeding effect time.

拟合值和观测值吻合的较好，计算出的平均直径、均方根直径、均立方根直径和粒子浓度与观测值也比较吻合；本文对两组个例的催化影响区域及可能采集到相应值的下风方区域进行了分析，催化下风向影响区的F-100、2DC、2DP的粒子浓度比背景值都有所增加，但是增加的幅度不同，应该是催化响应时间的原因。

This paper studies a class of cubic system with planar polynomial.We use the qualitative theory of ordinary differential equations method of analysis, reached the following conclusions of four parts: First, we analyze the quality of all critical points of the system,and draw the conditions of existence of singular integrals for the system , in front based on the analysis, using Pioncare form series method to calculate the focal value of o(0,0). Finally, we also study the behavior of critical points at infinity.
