The influences of melt pre-injection shot  gas pressure  delay time and melt temperature were observed by using multi-factor orthogonal experimental method. According to the analysis of the factors' impact on evaluation index  the optimized parameter combination is obtained. Therefore the optimization design of technological parameters is done. The results show that during the gas-assisted injection molding  optimum pre-injection shot is 94%  gas pressure is 15MPa  delay time is 0.5s  melt temperature is 240 C. This study provided a more practical approach for the gas-assisted injection molding process optimization.   A comparison study on Gabor,Chirplet, FM(m)let atom databases for ECG signal processing 会议论文 3rd International Conference on Bioinformatics and Biomedical Engineering, JUN 11-16, 2009 作者:  Meng, QingJie;  Sun, Nongliang 收藏  |  浏览/下载：1/0  |  提交时间：2019/12/31 matching pursuit  sparse decomposition  FM(m)let  time-frequency atom  database  index parameter   parallelization of fm-index 会议论文 10th IEEE International Conference on High Performance Computing and Communications, Dalian, PEOPLES R CHINA, SEP 25-27, Zhang Di; Zhang Yunquan; Liu Shengfei; Huang Xiaodi 收藏  |  浏览/下载：11/0  |  提交时间：2011/06/13 FM-index  Self-index  Block processing  Parallel computing  Multi-core   efficient construction of fm-index using overlapping block processing for large scale texts 会议论文 29th European Conference in Information Retrieval Research (ECIR 2007), Rome, ITALY, APR 02-05, Zhang Di; Zhang Yunquan; Chen Jing 收藏  |  浏览/下载：12/0  |  提交时间：2011/06/29 FM-index  self-index  block processing
