In order to further predict the durability of the TS-1 catalyst in the severe condition of calcination regeneration, a catalytic deactivation method was employed to facilitate the obtaining of deactivated catalyst from the regenerated sample, and thus the conduct of repetitious regenerations.

研究了负载成&蛋壳型&的TS-1催化剂在丙烯环氧化的单管放大试验装置上连续运转1 200 h失活后的焙烧法再生条件，并结合催速失活，对该催化剂进行了多次焙烧再生研究。

Additionally, some shortages and problems about sea-level researches are listed, and preliminary improving measures concluded include:(1)using more precise dating technology to minimize errors;(2)carrying Out researches on tectonically stable locations;(3)adopting more precise sea-level indicators such as microatolls and tubeworm encrustations.

最后还指出了研究过程中存在的主要问题与不足，并初步总结出一些改进措施：①使用高精度的定年技术，减少年龄误差；②在构造相对稳定的海岸段研究古海平面变化；③尽量采用高精度的标志物，如微环礁、管形虫壳等。

By dividing the coil and drift tube into single rings current,the computa- tion model for the magnetic field produced by the coil and the eddy current of the drift tube is developed.

在对外加电流线包产生的磁场的计算和漂移管的涡流效应进行深入分析的基础上，提出了基于单个圆环电流剖分的线包磁场计算方案，并用C++面向对象编程技术编写了用于计算线包磁场的类模块添加到XOOPIC软件包中。

The basic thoughts of applying genetic algorithms in pipe network design is: concerning the objectives of pipe diameter, defining the costs of pipe network as objective function, and considering hydraulic situation(continuous equation and cycle equation of the crossover of pipe network), velocity of flow of pipes as restraining elements, this thesis carries out the optimal calculation on the design of pipe network.

运用遗传算法进行管网优化设计的基本思路是：将管网管径作为求解对象，以管网造价为目标函数，以水力条件（管网节点连续方程和环方程）、管段流速作为约束条件进行优化计算。

However, trachea cannula exodus of terylene tandem ring alloy composite artificial esophagus in middle and late phases cannot be fully solved.

但带涤纶连接环记忆合金组合式人工食管还存在中晚期脱管的问题未能完全解决。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
