From an investigation and collection of specimens of terrestial isopoda in 20 sampling areas throughout 5 typical zones (i.e.,tropical,subtropical,warm temperate,temperate and high frigid) in China,a total of 11 families,29 genera and 72 species of terrestial isopoda were found.Due to the great zonal differences in the environmental surroundings,there are diversities in species distribution.Tropical and subtropical zones are mostly rich in number of species with a total of 38 and 47 species respectively,making up more than 80% in total.Only 9 species were found in temperate and warm temperate zones.In high frigrid region,due to the average temperature which is below zero degree celsius and which is unfavourable for the existance of terrestial isopoda,only 2 species were found.

The fig-pollinator mutualism system is maintained by the reproductive relationships.In the way of dissecting syconia,and using statistics and comparative observation,diversity of pollination system of six species of figs in the northeast of Fujian and their mutual insects are studied.The result shows that flowers of the six figs can be divided into female flower,gall flower,male flower,and bisexual flower.The sex expression of the individuals of each fig species including dioecism and gynodioecy.The female and gall flowers have or have not pedicel (pistil stem) single-layer or double-layer range.The male flowers have distributive forms of dispersively-living,semi-collectively-living and collectively-living.There is difference in size of syconia,the number of flowers,the number of scales and distributing area of their function,and the form of forming outlet holes,which has homologous behavior of fig wasps.Each fig species usually has one kind of pollination insect,and the six fig species and their pollination insects respectively form their own independent pollination systems.It is obvious that such pollination systems have rich diversity.Each mutualism system has different choices of evolution to pollinating biology's character.This reflects the suit of both side of the mutualism evolution and reproductive strategy.Then it safeguards the stability of mutualism system.

With the popularization of computer networks,there has been a shift proposed in distributed system programming from the remote procedure call to the remote programming paradigm,to decrease network traffic and improve performance.Software agents could be used to accomplish this task.The use of agents has several advantages and a few disadvantages,including added security issues.In order to implement autonomous security of Java agent,the author presents a new module system for Java that improves upon many of the deficiencies of the Java package system and gives the programmer more control over dynamic linking.Next,the author develops a general agent model and discusses general security issues in that model.Finally,the author proposes a practical solution that addresses some of those security issues.

As an important variable,expectation price affects the behaviors of consumer and producer in micro-market.Expectation price of producer contains not only the past expectation price and real price but also the past supply and demand.Price changes with the relation of supply and demand.Under certain scopes,the intrinsic adjustment mechanism(invisible hand) may demand price.But price has no longer the stability if it goes beyond the scope and the market ineffectiveness may take place.
