零点

In this project,we primarily investigated the growth of solutions of some types of differential equations,and the hyper order,the exponents of convergence of zeros and fixed points of solutions with infinite order, especially, expononts of convergence of fixed points of first, second order derivatives and differential polynomials of solutions.

Besides, I was one of the early fans of Caribbean baseball----or el juego de pelota, as we called it in the vernacular.

还是在Cataca时我被Luis Carmelo Correa传染上的足球狂热已经几乎降到零点了，另外，我仅仅是加勒比棒球（或者el juego de pelota，如我们在本地的叫法）的一个早期的球迷。

From our results we know that the average error of the Lagrange interpolation sequence and the Hermite interpolation sequence based on the Chebyshev nodes in the 1-fold integrated Wiener space equal weakly to the average error of their corresponding optimal approximation polynomial in the 1-fold integrated Wiener space,and as a kind of information-based operation,they have simple form and their recover functions are polynomials,in the 1-fold integrated wiener space,their average error equal weakly to the corresponding minimal information radius whose permissible information operators class is function values.

通过我们的结果可以知道，基于第一类Chebyshev多项式零点的Lagrange插值算子列和Hermite插值算子列在1-重积分Wiener空间下的平均误差弱等价于相应的最佳逼近多项式在1-重积分Wiener空间下的平均误差，并且作为形式简单且恢复函数为多项式的一种信息基算法，其在1-重积分Wiener空间下的平均误差弱等价于相应的以函数值计算为可允许信息算子的最小平均信息半径。

Phase angle refers to the relation between two sine waves which do not pass through zero at the same time.

相角 ：相角指的是两个不同时经过零点的正弦波之间的关系。

In this paper a method for design of constant phase shift network, which can be used to improve the dynamical characteristics of feedback systems with variable open-loop gain, has been proposed.

本文讨论用于改善开环增益可能会有较大变化的反馈系统的动态特性的"等相移网络"的设计方法，并采用了优化的计算程序来求出极、零点的最佳位置，从而得到了一个在计算机上实现的最优设计法。

In terms of hardware bring forward the zero-crossing detection to compensate for the phase lag caused by filter.

硬件上通过提前过零检测来补偿加重滤波器带来的相位滞后；软件上加入判定过零点真伪的功能。。。

The instrument simultaneously sample for three phase voltage and current. Rotary photoelectric coding switch and LCD are used for human-computer interaction. it makes the interface compact and efficient. Utilizing the function of positive and negative edge trigger of the programmable counter array unit in MPU, signal zero-cross is captured for the phase detected based on double way. The software synchronism sampling method based on real-time parameter self-optimizing minishes period truncation error, and the measurement accuracy is improved. The digitization power measure imports traditional two-unit and three-unit methods and expands application range of the instrument. The capacity is discriminated by soft ware table-look-up on the load loss. The value of a quantity is converted to the value when reference temperature (75 ℃) from test temperature.
