Allen and co - worker did ab initio calculation to test the adequacy of scf mo calculations for predicting molecular equilibrium geometries 爱伦及其同事应用从头计算法来考查scf mo计算对于预示分子平衡几何形的适宜性。
Currently scf sponsors more than 20 , 000 students annually and every university student receives rmb2 , 500 per year 目前上海市慈善基金会每年资助学生20 , 000人，资助本市家境贫困、品学兼优的大学生每人每年人民币2 , 500元。
Results applications including enzyme catalysis in scf fermentation in scf , scf sterilization and cell disruption were reviewed 结果已在生物工程领域应用的超临界流体技术有超临界流体酶催化、超临界流体发酵、超临界流体灭菌和细胞破碎技术等。
In the last chapter , it explains the significance of scf : 1 ) it is a useful implement to the investor . 2 ) it indicates the ability of payment of the enterprises 该章强调的是:这一章所使用的“经营活动产生的现金流量”是指该指标2一4年的平均值。
In the signal transduction system , c - kit is in the upstream as the stem cell factor ( scf ) receptor , while c - myc in the downstream as a target protein 在信号转导系统中， kit是干细胞因子( steelcellfactor , scf )的膜上受体，位于信号级联的上游，而myc处于下游。
Two pgcs were cloned to forth passage supplied with lif and scf . pgcs were cloned to third passage supplied with lif and scf on feeder cell . pgcs has the characterization of es - like 采用饲养层培养法，在培养基中添加lif和scf ，分离到了原生生殖细胞，并有2个pgcs集落传至第3代。
It is benefit for blastocysts attached and icm proliferation to supplied with lif and insuine . the es - like cell can be cloned with insulin , and cloned to passage one , nor es - like cell with lif Lif和scf联合使用与对照组相比可提高类es细胞的增殖率( 52 . 9 : 7 . 7 ) ，并且有两个类es集落传至第4代。
Some initial cryptanalysis and detailed statistical tests of scf are given , the results show that scf can resist some known cryptanalytic attacks and has excellent statistical properties 并且对scf作了一些初步的密码分析和详细的统计测试，结果表明： scf密码足够抵抗一些已知的密码分析、具有很好的统计性能。
In this study , the putative eg cell culture media was supplemented with lif , bfgf , scf and igf - 1 . as a result , the ideal dose of lif , bfgf , scf and igf - 1 was : 100iu / ml , 10ng / ml , 10ng / ml , 10ng / ml 而随着培养时间的延长，添加lif 、 bfgf 、 scf 、及igf - 1组表现的优势越来越明显，对促进类eg集落的持续增多效果最佳。
Atlas of stress distribution and graphs of stress concentration factor ( scf ) were obtained . the atlas and the graphs showed that the scf at the joint crease nonlinearly with the accretion of r / r and the minuet of t / t 结果表明连接点处有明显的应力集中，并且这种应力集中是随着开孔率增大和厚度比减小呈现非线性增长的。
