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.
