It analyzes in detail the applied technology and keytechniques, including geometric modeling, assembly, joint design, database linking and management. The application of WFCAD in furniture manufacturing enterprises and its further improvement are outlined.展开更多

The results indicate that the indoor air quality (IAQ) of the dormitory is very poor and it is far beyond the acceptable standard of the IAQ. The discontentment rate of the IEQ in the dorm is rather high, and the factors affecting the IEQ concentrates on the air pollution, awful smell, thermal comfort, narrow individual space, etc. Also the spot tests were done in a university in Chongqing, and the results indicate that the 6 indexes, such as indoor temperature, humidity, the density of CO2, SO2 and dust,the total bacterium, etc, are far beyond the correlative standard.展开更多
