A simulation-based model is applied to describing the phased-mission system with multi-repairer. Algorithms for calculation of the optimization quantity of spare parts are provided. To examine the applicability of the method, some examples are presented in this paper. Finally, the optimization quantity of spare parts following exponential distribution are calculated with both this method and analysable method.

Methods: 1. Male Sprague-Dawley rats were established renal calcium oxalate calculi model. 2. The different dose of LBP, medlar soak and apozem was given. The calcium oxalate crystallization, the renal cell apoptosis and the renal free radical level were detected. 3. The relationship of the renal cell apoptosis index, the renal free radical level and the calcium oxalate crystallization grade in the kidney tubule was determined.

The result showed that the content of soil carbon indices on slope cropland were lower and increased dramatically in linear pattern after the cropland were abandoned for some time. 50 years after abandonment, OC, AOC and NAOC would increase by 169%, 144% and 210% respectively, compared to the slope cropland and would be 35 %, 39 % and 33 % respectively, of t he natural Chinese arborvitae stand. The carbon pool index and carbon pool management index would sharply increased by 169% and 117%, comapared to the slope cropland would increase by 35% and 42% respectively, compared to natural Chinese arborvitae stand.

Using RAPD markers techonolgy analysed the genetic structure of populations and built up the reaction system of SSR markers of Aristida pennata, at the same time, analysed the genetic structure based on SSR markers techonolgy. The research results are as follow:(1) 11 amplifiction random primers were used to detecte 125 loci in 76 samples. The total proportion of polymorphic loci of. Aristida pennata is 96.8%, the average proportion of polymorphic loci of Aristida pennata is 45.3%. The analyses of Shannon diversity index (1,0.5151) and Nei gene diversity index(h, 0.3471) indicate that the gene variation is rich in subpopulations.

Pennata.tirn为研究对象，在阜康，147团及121团周边等7个亚种群采集76个样品，通过RAPD分子标记技术进行亚种群内和种群间的遗传变异分析，并采用SSR技术建立羽毛三芒草的检测技术平台同时进行遗传结构分析，结果表明：(1) 11条RAPD引物检测到76个样品有125个位点，总多态位点百分比为96.8％；亚种群内平均多态位点比为45.3％，香农表型多样性指数(1，0.5151)，Nei's基因多样度指数(h，0.3471)都说明羽毛三芒草种群有较为丰富的遗传变异。
