Therefore, with some engineering and biological measures, after some pioneer trees are planted in extremely degraded tropical areas,the pioneer forest should be reformed by multilayer and multispecies broad leaved mixed forest in time, wihich could accelerate the development of artificial forest into local climax community.

因此，对于极度退化的热带丘陵台地区，在一定工程和生物措施基础上，用先锋绿化树种造林成功后，及时用多层多种的阔叶混交林改造原有先锋林，可以加速人工林向地带性植被类型演替。

In the past, the mainframe computers were used widely in hospitals. This kind of closed architecture provided centralize-control safety technology and multiple secure protections.

在以往医疗机构的资讯网路架构大多为较封闭性的大型主机中央控管系统，这类型的中央控制安全技术，经过多年精鍊后，变得非常成熟，所以系统多半拥有多层的安全保护，但封闭性大型主机因为建置及维护成本非常高，常需高额的预算与人力的投资。

In the paper, the via minimization problem in multi layer routing with adjacent constraints is translated to a k colorable problem which has more general meanings, and a mean field annealing algorithm for the k colorable problem is proposed.

该文把具有相邻约束的多层通孔最小化问题转换为更具广泛意义的 k-着色问题，并提出了 k-着色问题的均场退火求解算法。

The results indicate that the Y5V dielectric powder prepared by MSS not only are homogeneous, excellent and intensive, but also is active, can be sintered 900~920℃and the dielectric properties are better than the columbite precursor method , can be applied with pure silver paste, the production cost of MLCC is able to reduced.

结果表明：熔盐法制备的Y5V电子瓷料粉体不仅颗粒均匀、形貌好、易分散，而且活性高，使得多层陶瓷电容器的烧结温度可以降低到900~920℃，其介电性能要优于传统的二步合成法制备的粉体，十分有利于采用全银内浆，大大降低MLCC的生产成本。

Condusion: There is direct correlation befweon the widening of Virchaw-Robin space around anterior commissure and age of patient.

前联合单纯性血管周围间隙扩大的程度与病人的年龄没有直接的关系，多层螺旋CT及MPd均能很好地显示病灶，对本病的诊断MPd优越于CT。

According to the results of comparison between these methods of spectrum evaluation, a new method of power spectrum evaluation of welding arc sound is advanced by means of association of wavelet packet analysis with the Welch average method .

对试验系统采集到的焊接电弧声进行了小波包多层分解，并利用周期图法、Welch 平均法及AR模型法，对各频段信号进行功率谱估计。根据不同谱估计方法的对比结果，提出小波包分解结合Welch 平均法对焊接电弧声进行功率谱估计的新方法。通过对几种规范与飞溅率下的电弧声功率谱的初步分析，发现其功率谱分布具有一定的规律性，并且不同频段谱峰值及其对应频率与焊接飞溅具有相关
