on this basis, the mathematic models for correlation of related circulation factor, efficiency of separators with particle characteristics of furnace burden, which are suitable to wide-meshed poor grade fuel with high ash content and low heating value,are proposed for the purpose of making design of fluidized circulation bed boiler more perfect.

At present there exist two different definitions for the circulation factor of CFB boilers, which is a major parameter for the design and operation of such boilers.

The chilling damage forecast model of Maize consider many kinds of influence of factor, such as atmospheric circulation factor, high field factor, sea warm factor and mean value cycle factor. Adopt the prediction model which predict factor integration more.

In this paper, the authors present a series of facts which can be used to explain the relationships between climate, included its circulation factor, and variation of earth ratation, and make interpretation about their relationships in physical respect.

Based on the analysis of autumn waterlogged process, the paper found out the circulation factor and the influence system of autumn waterlogging in Yuncheng, and carried on the examination of numerical forecast product to enhance the forecast accurate rate of waterlogged weather process in autumn.

Then, we analyzed the background causes of the disasters from the respects of geographical location, circulation factor, landform, geological structure and human factors.

Basing on climate sectoring, inter-decadal variability of precipitation is discussed for the first time series and every representative station, and the coefficient between the first time series and the prophase circulation factor is calculated on the 500 hPa geopotential height in northern hemisphere.

the outbreak date of South China Sea Summer Monsoon in 2003 was later than normal and the tropical monsoon was weaker than normal, its monthly change was like 1991, and this is the circulation factor for the rainfall to sustain in the Huaihe River basin.

A Basic heat balance equation treating the relationship between the different relevant variables and a formula for calculating the circulation factor of a waste incineration circulating fluidized bed boiler is being derived by making use of its thermal calculation.

and the Somali jet is the principle and stable cross-equatorial flow,and also an important circulation factor which affects the summer precipitation in the east of northwest China.

The circulation factor is around 46% and the furniture factor around 29%.

The time coefficients of the first 5 EOF's terms are obtained from the analysis of the 5-day mean circulation at the 500-mb level over Asia for the period of 1964-1973. By using the cross-spectral analysis method, the features of the relation in the frequency region between the 5-day mean circulation at the 500-mb level and the 5-day mean surface air temperature in our country are studied. And the main freguency bands in which the coherence function is significant in statistic meaning, are found....

The time coefficients of the first 5 EOF's terms are obtained from the analysis of the 5-day mean circulation at the 500-mb level over Asia for the period of 1964-1973. By using the cross-spectral analysis method, the features of the relation in the frequency region between the 5-day mean circulation at the 500-mb level and the 5-day mean surface air temperature in our country are studied. And the main freguency bands in which the coherence function is significant in statistic meaning, are found. On this basis the paper goes further into the time-space structure showing these relations. The results may provide a new fundamental and a new way for researching long-range weather proccesses and forecasting the 5-day mean surface air temperature with the circulation factors.

In this paper, the authors present a series of facts which can be used to explain the relationships between climate, included its circulation factor, and variation of earth ratation, and make interpretation about their relationships in physical respect. The space characters and time scales of weather-climate influenced by the variation of earth rotation's velocity have been discussed.

ABSTRACT Based on the average yield of early season rice in the period of 1962-1981 in Guangxi and using the integrating method of the Bayes′discriminatory and the regression analysis, from qualitative to quantitative, established a grade by grade yield forecast model in large scales.

ABSTRACT Based on the average yield of early season rice in the period of 1962-1981 in Guangxi and using the integrating method of the Bayes′discriminatory and the regression analysis, from qualitative to quantitative, established a grade by grade yield forecast model in large scales. The yield forecast model was established by two steps. The first is to select the atmospheric circulation factors which are closely related to the meteorology yield and to establish the Bayes′qualitative discriminatory equation to discriminate the future meteorological yield that belongs to positive value or negative value, i.e. yw≥o or y_w<0. The next is, on the basis of primary qualitative forecast methods; according to historical years such as the meteor-logy yield of y_w≥0 or y_wfactor and to establish secondary quantitative forecast methods A and B by using the statistical model. Two grades forecast methods of early season rice yield are agelong and of better extensionality. The underwent goodness f fit test of historical years reached to a hundred per cent. good results were achieved in try report and forecast.
