Let Un the Chebyshev polynomials of the second kind and the associated functions In this paper we discuss the approximations of the partial sums for the biorthogonal series based on and the corresponding conjugate series.

记Un是第二类Chebyshev多项式，伴随函数，这里讨论基于的双正交级数和其共轭级数的部分和逼近问题。

A series of studies suggested that metacognition plays a important role in concept formation, deductive reasoning and resolving insight problem, and a series of contradistinctive experiments about training of strategies and metacognition in process of learning, confirmed the feasibility and essentiality of training of metacognition.

它既体现了人在认知活动中的意识性、反省性、自主性，同时通过元认知知识、元认知体验、元认知监控等一系列元认知机制，将零碎分散的关于人类认知的研究发现综合成一个完整的人类认知的图画。

In series II, the artist extracted elements from the first series, reconstructed them based on their color, shape and size. The elements are placed on a contrasty background consisting solely back and white, forming pictures that are harmonious and chromatic.

移山之二，作者将移山之一里几乎所有元素分离后，按色彩，形状，大小，重新协调组合起来，用剪贴的手法放在黑与白的鲜明对比之中，形成一个整体上均衡安定且色彩夺目的画面。

This design separately uses series linear constant voltage circuit, series regulate constant current circuit and the feedback type contravariant circuit to design direct current constant voltage power supply, direct current constant current power supply and DC-DC converter.

本设计分别用串联型线性稳压电路，串联调整式稳流电路和反馈式逆变电路设计直流稳压电源，直流稳流电源和DC-DC变换器。

And the radius of convergence of the differentiated series is the same as for the orginal series.

逐项求导后所得到的幂级数和原级数有相同的收敛半径。

And the radius of the convergence set of the differentiated series is the same as for the orginal series.

定理5 如果幂级数的收敛半径为则其调和函数在内可导，且有逐项求导公式

Power series, radius of convergence; function that can be expanded in a power series on an interval.

幂级数；收敛半径；可展开为幂级数的函数。

The positive number is called the convergent radius of power series, and is said to be the convergent interval of power series.

正数通常叫做幂级数的收敛半径，开区间叫做幂级数的收敛区间。

Theorem 8 If the series converges absolutely, the series must be convergent.

定理8 如果级数绝对收敛，则级数必定收敛。

If each term of the series u1+u2+…un+…is continuous on the interval［a,b］, and this series is uniformly convergent on［a,b］, then its sum function is also continuous on ［a,b］.

若级数u1+u2+…un+…的每一项在［a，b］上连续，而且这级数在［a，b］上一致收敛，则它的和函数也在［a，b］上连续

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。

On one hand, there are discussions with the works council and union about extension of short time working up to the end of September.

一方面，有讨论，工程理事会和联盟关于延长工作时间短至9月底。
