飞机成员开发中编队调整问题的处理

在基于HLA的仿真成员开发中,成员中对象间的跨成员通信是通过RTI进行的,成员内部的对象间通信是通过对象间发送消息来实现的。但是,在某些情况下,对象间的通信方式可能会动态改变,高分辨率的飞机成员开发中的编队调整问题就属于这种情况。针对这一问题,该文提出了四种解决方案,包括:统一用跨成员交互进行通信,利用所有权转移来实现,重新划分成员和基于成员框架的实现,并对每种方案的可行性进行了分析,然后详细讨论了基于框架的解决方案。

《毛公鼎》构词法研究

本文以《毛公鼎》中的复音词为研究对象,通过定量、定性的研究,发现复音词的语义、词性构成比较甲骨文有进步,与同时期的《诗经》也有不同。偏正式是最能产的构词方式,述宾式、主谓式、动补式还没有产生。

Gamete formation reflects the sexual pheromone hierarchy ofDictyostelium giganteum

Summary Sexual development inDictyostelium giganteum begins with the appearance of small, amoeboid gametes that fuse to produce mainly binucleate cells which differentiate into zygote giant cells. The data presented here show that the number of gametes produced by each strain (WS589>WS606>WS607>WS588) is directly related to its position in this hierarchy.This work was supported by a grant (A6807) from the Natural Sciences and Engineering Research Council of Canada.     

Biological effects of trilostane in vitro on oocyte maturation and fertilization in the hamster

Summary The effects of the inhibition of steroidogenesis by trilostane on oocyte maturation were examined by studying spontaneous maturation and fertilization in vitro. 10^–6 M trilostane had no influence on the meiotic process, whether the oocytes were naked or not. At a concentration of 10^–6 M and 10^–7 M trilostane, low normal pronuclear formation and high polyspermy were found during in vitro fertilization. However, no retarded male pronuclear development could be detected in the trilostane-treated group. Thus, steroid producing activity within ova is apparently necessary to prevent multiple sperm penetration, but it has no effect on meiosis or the action of the so-called male pronucleus growth factor (MPGF).
