Since 1988, air temperature, humidity, air quality, noise level and intensity of illumination in lots of dancing halls in China have been investigated and tested. This paper introduces the present situation of indoor environment and air conditioning systems in dancing halls of China. The design indexes of cooling load for room and ontside air are recommended. The reasons for indoor environment deterioration have been found out. From the actual situation of China, the ways for imoroving indoor environment and approach of energy conservation in air conditioning systems are explored. 相似文献

In this paper, the problems to be studied and solved after China entered the "Aging Society" are presented. Then, based on analysis of the living mode of aged, the complex mode of providing for the aged by combining the family supporting with social supporting is presented. Finally, to study, design and construct the housing suitable for the complex mode of providing for the aged, the welfare building and recreation center for aged is suggested. This paper will play an important role in investigation of mode of providing for the aged with China's character and promoting the construction industry to meet the needs of aging society. 相似文献

Masonry buildings with R/C frame- shear wall in the bottom storey have been widely used in city construction, which include two kinds of lateral force resistant system. However, the seismic behavior of the building is poor. Based on the characteristics that the rigidity of the upper masonry structure is much bigger than the rigidity of laminated rubber bearings and frame structure. It can be referred to as system having a two degree of freedom. The dynamic behavior of this building is analyzed, the isolated vibration mode controls the response of system. The authors give apractical method for dynamical analysis to masonry building with frame structure in the first storey with laminated rubber bearings between the first and second storey , which submits efficient path to found applicable design means and to generalize interlayer seismic isolation structure. 相似文献

With the increasingly economic competition in the World, the audit industry, numerous investors and the enterprises pay more and more attention on the audit of company's sustainable operation. In view of existing situation that the audit on the capacity of sustainable operation attach main importance to the finance of the audited company, in the result, it is difficult to recognize it completely. The model of the balanced scorecard is used, an indicator system that combine company's finance condition and non-finance condition is built in the sustainable operation audit. Basing on the way to process non-dimensional quantities of indicators, the audit use the analytic hierarchy process to determine the weights of the evaluating indicators and take the degree of gray incidence as the evaluation criteria. 相似文献

This article summarizes the theory achievements,arguments,the investment and ownership concentration model which studied in investment-cash flow and the stockholder's rights structure questions.The financing restraint is explained.The special social stratum shareholder is elaborated which influences relation between investment and internal cash flow by the financing restraint existing in the enterprise,the management opportunism hypothesis and the information assymetrical theory separately.Finally the authors induce and study the real diagnosis model of the supposition(above).The model is important for the empirical study of ownership structure influencing to corporate investment. 相似文献

Summary Soybean DNA fingerprints were analyzed by digoxigenin-labeled oligonucleotide probes complementary to simple repetitive sequences. The clearest and most polymorphic patterns were obtained with (AAT)6 as a probe, with which all 47 soybean cultivars tested could be distinguished. However, DNA fingerprints of individuals within cultivars showed the same pattern. Using (CT)8, (GAA)5 or (AAGG)4 as probes, clear polymorphic patterns among cultivars and accessions in the subgenus Soja (Glycine max and Glycine soja) were not observed, while quite different patterns were found in accessions in the subgenus Glycine. The results suggest that G. max and G. soja are closer in their genome structure. DNA fingerprints of reciprocal crosses between cultivars and accessions in the subgenus Soja were similar, and contained bands of both parents. In an F2 population from these crosses, such bands segregated in a Mendelian fashion. 相似文献

Summary The effect of genotype, growing conditions for donor plants and type and concentration of carbohydrate in the culture medium was investigated for anther culture of head cabbage (white cabbage, savoy cabbage, pointed-headed cabbage). Strong genotypic effects on embryo formation from the cultured anthers were shown as well as superior embryo formation from anthers of field grown donor plants compared to plants grown in the greenhouse. When comparing 7, 10 and 13% sucrose in the medium, embryo response increased with increasing sucrose concentration. With maltose, which was generally inferior to sucrose as carbohydrate source for anther culture, the embryo response did not increase with maltose concentration above 10 per cent. 相似文献
