This thesis systematically studies the comparativeness of Chinese trade in services in four aspects of indices basing upon existing achievements by using quantitative analysis method and qualitative analysis method. Moreover, the indices have been compared with those of the five transitional countries in the same timing period. Three points can be drawn from that study. First, the comparativeness of Chinese trade in services are too weak to compete internationally. Secondly, tourism is the only industry that holds its comparative advantage. Finally, we can learn from what the Poland and Hungary have been doing with their trade in services.

本文采用了定量分析与定性分析相结合等研究方法，在前人研究的基础上，对1995-2000年我国服务贸易的国际市场占有率、比较优势指数、显示性比较优势指数和显示性竞争比较优势指数四个指标进行了计算，较全面、系统地分析了我国服务贸易的国际竞争力，并首次将该四项指标结果同一些转轨经济国家的相同指标进行跨国比较，从中得到三点启示：1、我国服务贸易整体不具备竞争优势；2、旅游业是我国服务贸易中具有较强比较优势的行业；3、波兰和匈牙利两国的成功经验对我国发展服务贸易有一定借鉴作用。

Spatial distribution pattern of larvae of Aleurocanthus spiniferus in citus garden was studied by means of some distribution parameters such as mean crowding, David and Moor's clustering index, index of patchiness, proliferation index, the distribution of negative binomial, Iwao's patchiness, the and Taylor's law. The results showed that the spatial distribution pattern of larvae under all densities appeared to be aggregation distribution, which is characterized by individual attraction and predominant individual group such as cored distribution pattern.

We present our Monte Carlo results of the random-bond Potts ferromagnet with the Olson-Young self-dual distribution of quenched disorders in two dimensions.By exploring the short-time scaling dynamics,we find the universal power-law critical behavior of the magnetization and Binder cumulant at the critical point,and thus obtain estimates of the dynamic expontent z and magnetic exponent η,as well as the exponent θ.Our special attention is paid to the dynamic process for the q=8 Potts model.
