Based on field survey and microstructure analysis the author considered that Yiwulvshan is a Cretaceous metamorphic core complex, and pointed out the time of Yiwulvshan granite is not early Yanshanian by the comprehensive analysis of the regional structures and isotopic dating, but a late Yanshanian granite.

在此基础上，作者经过野外宏观观测和室内显微分析，基本厘定医巫闾山是一个白垩纪形成的变质核杂岩。根据区域构造演化综合分析及同位素年龄测定，认为医巫闾山花岗岩体时代并非前人所定的早燕山期，而是晚燕山期岩体。

The research results are as follows:1. EpNPV is a kind of nuclear polyhedrosis virus.

A general trend in the research of symbiosis in ciliates is further exploration of the influence of the symbiont on the gene structure and gene expression of the host. The expected results will contribute to a better understanding of the regulatory mechanisms controlling the interaction,the exchange of substances between the host and symbiont at a molecular level, and the pattern of life processes sur rounding the relationship between cellular structures and functions in eukaryocytes.

作者推测，探索共生体对宿主基因结构及其表达产物的影响可能是对纤毛虫中共生作用研究的主要趋势，这对于深入了解真核细胞中宿主-共生体双方的相互作用、物质交流在分子水平上的调控机理、细胞结构与功能的关系等细胞生命活动规律是有意义的。
