3 . by using the techniques of an explicit criterion to determine the number of real roots of a univariate polynomial in ( [ 13 ] , [ 73 ] ) ; b - net form of bivariate splines function ; discriminant sequence of polynomial ( cf . [ 13 ] , [ 73 ] ) and the number of sign changes in the sequence of coefficients of the highest degree terms of sturm sequence , this paper determines the number of real intersection points two piecewise algebraic curves whose common points are finite . a lower bound of the number of real intersection points is obtained in terms of method of rotation degree of vector field 大连理工大学博士论义:分片代数价线i片代数簇的若十m穴3 :利用杨路,张景中,侯晓荣在文献v13 , 73 )中关于一元多项式实根的显式判准,以及二元样条函数的b网形式,多项式的判别序列和sturm序列的最高次数项系数序列的变号数,本文给出了两个分片代数曲线的丈交点数(假设公共点是有限的)的计算公式。
The off - line data for network topology determination are always achieved by hand , and the coding of the equipments and their common points is tedious . so the paper proposed the intelligent search method of width - first searching to coding the network connection automatically and studied it 结线分析所需要的离线数据通常是手工完成的,设备的编号以及公共连接点、端点的编号是其中麻烦而容易出错的部分,本文提出用宽度优先的智能搜索方法进行网络连接关系的自动编号,并对该方法进行了研究。
This paper aims at the big development in the world along with the modern city , its common point of chaperonage of continuously enhance , and the city of the different region is characteristic gradually disappear , namely the area is cultural after this inherit and development face the big crisis of an important problem , bring upped our some standpoints and concrete solutions 本文针对随着现代城市在全球化进程中的大发展,伴随其共性(高技化)的不断加强,不同地区的城市特色正在逐步消失,即地域文化的继承与发展正面临着莫大的危机的这一重要问题,提出了我们的一些观点与具体解决办法。
Thirdly considering that the crux of the integration of the two management systems is to solve the problems of the overlap and intersection of some system aspects , so comparative study and the principle of seeking common points while reserving difference are employed . fourthly die same running mode as that of iso14001 or ohsms is adopted to be that of the integral management system of esh ( called in this dissertation ) because the two management systems take like running modes 为此,作者在基于对iso14001和gb t28001分析、对比和提炼的基础上,运用前述的思路和方法,研究出了环境管理体系和职业安全健康管理体系一体化后的标准模式(本文将一体化后的体系称为环境、安全与健康管理体系,即esh俗或esh一体化管理体系) 。
Consider three mutually perpendicular coordinate lines ( the - , - , and - axes ) with their zero point at a common point , called the origin . the three axes form the right - handed system , that is , if the fingers of the right hand are curled so that they curve form the positive - axes toward the positive - axes , the thumb points in the direction of the positive - axes 空间中三条相互垂直的坐标线,它们的零点相互重合,称为原点,记为.坐标轴遵循右手法则,即以右手握住-轴,当右手的四个手指从正向-轴以角度转向-轴时,大拇指的指向就是-轴的正向
