STUDY OF THE HEAT AND HUMIDITY TRANSFER PROCESSES BETWEEN AIR AND WATER IN THE AIR WASHER

The processes of heat and humidity transfer between air and water are what to be studied mainly in the paper, we put forward some main factors which influence the processes of heat and humidity transfer in the air washer. We come to the conclusion that we can change these main factors to achieve different heat and humidity transfer processes and decide processes of heat and humidity transfer of air and water with the initial temperature of spraying water in the air washer. All these results can make things convenient for the air conditioning management.     

LAND SUPPLY AND HOUSING PRICE:THE CASE IN HONG KONG

In this study we examine the relationship between land supply and housing price, percentage of land premium in the total government revenue and housing price, with reference to Hong Kong from 1981 to 1994. To do this we employ the Granger causality method to test the underlying hypothesis whether Hong Kong Government adopt high land-price policy. We use the first difference of data to ensure the stationarity in time series with the help of augmented Dick-Fuller unit root test. The results of the paper suggest no strong evidence to support the view that the land control of the government has caused soaringly rising housing prices. The findings also apparently implicate that the government has the revenue-maximizing behavior which is consistent with efficient allocation of resources.     

高校档案信息资源开发利用的思考

档案的收集和开发利用二者的辩证关系是档案工作的内在规律，收集工作是开发利用工作的条件和前提，开发利用工作是整个档案工作的最终目的，高校档案收集工作和开发利用工作的实践中，应当使二者紧密地统一。

复杂目标散射近区RCS特性预估的研究

本文运用物理光学法（PO）和等效电磁流法（EMC）分析和计算了平板、多面体及某船体等复杂目标的近区单站RCS。作为例子，文中给出了一些目标的“近区”和“远区”单站RCS的比较。数值结果表明：目标“近区”和“远区”的单站RCS特性存在差异，而且这种差异随着目标形体复杂程度的增加而增加，其近区单站RCS特性亦变得复杂起来。该结果可为军用目标近区RCS的预估、雷达截面的减缩、隐身与反隐身、对抗与反对抗、目标别识、目标散射特性的缩比研究和远近场变换等相关的电磁工程技术实验和理论研究提供一定的理论依据。
