This paper implements the symbol analysis of circuit and obtains analytical expression with the powerful symbol operation of the Matlab,provides an efficient assistant method for circuit analysis.

由于用符号表示的解析式比数值解具有更好的

Finally it analyzes the feasibility that using hydromechanics to analyze traffic flow by contrasting various characters between traffic flow and fluid flow. It analyzes influence of road alignment to basic expressway segment capacity by hydromechanics, and obtains viscous resistance and viscous movement differential equation when the vehicle drives on circular curve segment of expressway. And it infers that viscous resistance is correlated with sideway force coefficient, slope of crown and radius of circular curve. Radius of circular curve, sideway force coefficient and slope of crown are bigger, viscous resistance is smaller, the influence to capacity is smaller when the vehicle is running on nearside lane of circular curve; but radius of circular curve and sideway force coefficient are bigger, slope of crown is smaller, viscous resistance is smaller, the influence to capacity is smaller when the vehicle is running on fast lane of circular curve.

最后通过对比交通流与流体流的相似性，运用流体力学分析了道路线形对快速路基本路段通行能力的影响，求出了车辆在曲线路段的粘性阻力，建立了车辆在曲线路段的粘性运动微分方程，并由此推知，粘性阻力与横向力系数、路拱横坡度和圆曲线半径都有关系，当车辆在圆曲线外侧车道上行驶时，圆曲线半径、横向力系数和路拱横坡度越大，粘性阻力就越小，对道路的通行能力影响就越小；而当车辆在圆曲线内侧车道上行驶时，圆曲线半径和横向力系数越大，路拱横坡度越小，粘性阻力就越小，对道路的通行能力影响就越小。

The characteristic is repeatedly, how much does defer, haemoptysis measure differ. Sign of model of ball of bacterium of music of X line clew person occupy 40.7%, not typical person 59.3%; and CT not only can ask for from X line model basis of first visit to a doctor gets in resembling, and can from its not typical ask for what " lunar halo obtains to ask for "" float lotus to ask for the ball of concerned Qu Jun such as " in resembling to diagnose clew. 44 routine fine raises 28 positive in lens scrutator, 39 routine biopsy person in 16 paradigmatic fact are Qu Jun ball.

特征为反复、迁延、咯血量多少不一。X线提示曲菌球典型征象者占40.7%，不典型者59.3%；而CT不但可自X线典型征像中得到初诊依据，而且能从其不典型征像中获得"月晕征""浮莲征"等有关曲菌球的诊断线索。44例行纤支镜检查者中28例阳性，39例行活组织检查者中16例证实为曲菌球。

This paper researches linear maps preserving orthogonality,obtains the linear maps preserving othrogonality,it is either a rank -declining or rank -keeping map or a map with nilpotent element in its codomain.

利用分块成向量的方法证明了MnMn(F为域F上所有n×n矩阵构成的乘法半群上的n×n拟正交矩阵组至多含有n个矩阵，利用方程组的解的理论证明了Mn中与给定矩阵A构成两两拟正交矩阵组的矩阵个数不超过n-Rank+1，从而得到Mn上保持拟正交性的线性映射φ要么是降秩的或者保秩的映射，要么φ的值域中含有幂零元。

Then it obtains a handle to the signal's slot list and combiner.

然后，它会获得一个句柄，指向信号的插槽链表与合并器。

And now, this system has come into operation in Xinjiang plant protection station for about one year, which obtains good effect.

With the development ofscience and technology,the author believed it could be measured for labor valuethrough the patterns of time commensuration,input commensuration and outputcommensuration;and it could be confirmed for immaterial value absorbed by materialcapital through comparing the production rate of different enterprises,therefore,it mustlead to the fact that equal capital obtains equal profit,which can explain thetransformation problems of economics.

本文认为，物化资本吸收的无形价值可以通过比较不同企业的劳动生产率来确定，因而必然表现为等量资本获得等量利润，由此可以解释经济学中的转形问题。

As a particular of Rado's theorem and the compactness theorem one obtains the following result.

It has been observed that the presence of weldlines significantly reduces the mechanical property of injection molded parts . Therefore, in recent years, the analysis on injection molded parts with weldline obtains global concerns, this is. on the one hand , due to large-scale complex parts gradually manifold , on the other hand, the people desires on the appearance and internal performance of parts are increasing high , how to enhance the performance on the weldlind area becomes investigative emphasis .

因为熔接线的存在显著地减少注射制件的力学性能，因此，近些年来，对注塑制品熔接线的分析得到了普遍的关注，这一方面是由于大型复杂制件的逐渐增多，另一方面是人们对制品的外观和内在性能要求越来越高，如何提高制品熔接线区域的性能成为研究的重点。
