查询词典 analytic function of several variables

Engineering design problems have two characteristics: the design variables are often monotonic in the objective function and constraints. Moreover, the objective function and constraints are often implicit functions which cannot be expressed explicitly in terms of design variables.

工程最佳化设计问题通常有两个特性：设计变数在目标函数与限制条件常具有单调性，且其目标函数与限制条件常为内隐式函数，也就是不能以设计变数来表示其外显形式。

Also, if a complex analytic function is defined in an open ball around a point x 0, its power series expansion at x 0 is convergent in the whole ball. This is not true in general for real analytic functions.

复解析函数则不同：凡复解析函数必为全纯函数（即复可导，以实变量表示则是满足柯西-黎曼方程），反之亦然，因此全纯函数与解析函数在复分析中是同一类对象。

Textbook is not only the primary basis for students to grasp knowledge and method but also resort and carrier to train capability. New textbook has been tested in some provinces and cities since 1997, some educational and teaching concepts in new textbook inosculates with new mathematics course which is being tested now, it has taken great role for the transition of teachers' teaching idea and students' learning way. This paper will analyze Plane Analytic Geometry high school textbook of 2004 edition which is published by People's Education Publishing House in some aspects such as content structure, educational function, psychological characteristic according with student cognizance and teaching through the method of content analysis, investigation, comparison and statistical analysis . The paper's purpose is to excavate the potential value of the textbook and understand educational idea and concept of new textbook so that students can grasp more basic thought of analytic geometry in teaching and can learn studying and discovering and solving problem ,at the same time it builds a kind of independent, disquisitive, cooperative and lifelong learning pattern.
