查询词典 parallel

Multiple trials is the basic concept of many parallel simulated annealing. It is to perform multiple trials at the same time to search acceptable solutions. The division simulated annealing with no communication and The clustering simulated annealing are two common types of parallel simulated annealing methods. The division simulated annealing with no communication makes each processor generate its own adjacent solution from its own current solution and compute the acceptance probability for a adjacent solution. Each of the processors searches solutions without communicating each other. Clustering simulated annealing makes each processor generate its own adjacent solution from a common current solution and compute the acceptance probability for each adjacent solution. Then, it decides which adjacent solution should be used to replace current solution according to a pre-specified rule.

许多平行模拟退火法之理论依据为多向试验，利用同一时间探索更多方向的试验来拓展搜寻的广度或深度，不进行沟通的分工模拟退火法(the division simulated annealing with no communication)以及丛集模拟退火法(the clustering simulated annealing)皆为平行化的模拟退火法，前者定义为各个处理器针对各自的起始解进行搜寻，产生各自的搜寻序列，在搜寻过程中处理器不进行任何沟通，各处理器仅针对自身之目前解进行搜寻；而后者定义为让所有处理器针对同一目前解进行运算搜寻各自的可能解，并各自决定其产出解之接受机率，最后根据事先决定之规则进行沟通比较，挑选其中一个可接受解取代目前解。

It is concluded that when a small solid angles range adjacent to the main direction in the far field is considered, the parallel beams combining of compact antenna arrays has its priority if the phases can be controlled, and the parallel beams combining of sparse antenna arrays has its priority if the phases can not be controlled.

分析表明：当关注的是远区主方向邻近的小立体角区域时，若能做到控相激励，宜采用紧凑阵的平行波束合成；若不能控相，宜采用稀疏阵的平行波束合成。

Chapter one mainly summarizes the basic theories with respect to parallel importing. Parallel importing which is also called "gray markets", are not generally considered illegal, in contrast to the "black" markets of stolen or counterfeit goods. Rather,"gray goods" are genuine in terms of their manufacturer, but their distribution is "unauthorized" by the holder of intellectual property right after their lawful first sale (note:"parallel importing" and "gray market" used in this article shall be deemed fungible).

因此本文在结构安排上不对三者划分截然的界限，本文采取总分结构，第一章为总论部分，着重概述三个领域的平行进口涉及到的共同问题，第二章至第四章是分论部分，将以国别为主线，着重介绍和讨论美国、欧盟以及其他国家和地区的立法和判例，对每一个国家而言，三者共同的地方进行综合论述，有差异的地方则分别进行论述。

ParaBase system also shows that the technical plan for"YH-3"parallel database system is feasible and successful and provides important supports both in techniques and in prototype for the final implementation. Owing to the prototyped system the roundabout course in the final implementation of"YH-3"parallel database system may be avoided or lessened. In addition, this prototype system provides an ideal platform for further parallel database researches too.
