- 摘要：In the past, the temperature was used as the sole quota to control the indoor thermal environment in hot summer and cold winter areas of China, but a major quota, the relative air moisture, was often ignored. In this paper, the effect of relative air moisture on indoor thermal environment is analyzed. The results show that the energy consumption can be reduced and comfortable thermal environment can be provided under natural condition by regulating the indoor moisture.507|1062|0更新时间：2023-11-28
- 摘要：On the basis of analyzing and summarizing the recent theoretical researches on constitutive models and failure criteria for brick masonry, a combination of a useful constitutive model with a reasonable failure criterion is used for describing the behavior of brick masonry under the loading in plane. A finite element program of nonlinear analysis is compiled. The predicted results are found to be in good agreement with Andreau's results.315|1163|0更新时间：2023-11-28

- 摘要：The composition and heavy metals content of sludge, solid wastes and coke breeze is detected in the test. Sludge, solid wastes and coke breeze compost the organic composite fertilizer. The experiments on it for rice fertilization were conducted. The results show that the contents of organic matter and N, P, K in wastewater sludge and solid wastes of Guilin are very abundant and heavy metals remain under the criteria. There is a significant efficiency for the organic composite fertilizer applied in raising rice yield, providing an extensive applicability.776|613|0更新时间：2023-11-28
