Microsoft chairman bill gates announced to employees today a major strategy shift across all its products , including its flagship windows software , to emphasize security and privacy over new capabilities 微软主席比尔?盖茨今日向雇员宣布，微软所有的产品将发生战略性转移，包括它的主打产品视窗软件，他强调安全性和私密性比新开发功能更重要。
In addition , homologous alignments and analyses of identical percentage were made between corresponding cdna sequences to cal homologs of 8 plants in the same family , brassicaceae . according to the information of above phylogenetic tree was drawn 另外，对8种十字花科植物cal同源基因中相应cdna序列进行了同源性比对和一致性分析，并据此绘制了它们之间的进化树。
The study , however , ran just 28 days and had conservative goals : to measure whether a resveratol formulation called srt501 , which is five times easier for the body to use than naturally occurring resveratol , was safe and had some activity in humans 虽然该研究仅进行了28天，而且研究目标保守：为了检测白藜芦醇制剂- srt501 （人体利用性比天然白藜芦醇高5倍）对人体是否安全有效。
The new algorithm bases on bisection and secant iteration , which is different cuppen ' s method and newton iteration . the results of theoretical analysis and numerical testing show that convergent rant of our algorithm is obviously faster that of the classical algorithm 该算法以割线法迭代为基础，明显不同与传统的newton迭代法，理论和数值实验表明改进的算法的收敛性比经典算法好
The topological description of ( - sheet has the advantage of simplicity , which makes it possible to implement very fast search and comparison algorithms . here , we present a general approach for aligning a pair of protein ( - topologies represented by two - dimensional matrices 我们提出一个用二维矩阵表示蛋白质( -拓扑的普适性比对方法，并对一些蛋白质结构重新进行分类，从而观察到不同的拓扑具有执行其特定功能的倾向。
Quality polymer sealants are noted for their ability to offer longer lasting protection than traditional carnauba - based waxes , but in recent years , there have been many inferior formulations marketed at extremely high prices giving consumers the impression they are superior , thus justifying the exorbitant price 它的长效持久性比传统的棕榈蜡效果要好，但是在近年来，有很多质量很差的配方也打着很高的价格在欺骗消费者。
Other experiments revealed slight variations in the size , number , arrangement , and interconnection of the nerve cells , but as far as psychoneuaral correlations were concerned , the obvious similarities of these sensory fields to each other seemed much more remarkable than any of the minute differences 其他的实验揭示神经细胞的大小、数量、排列和连接的细微变化，但就神经关联而言，这些感觉区域的相似性比那些细微的区别更有意义可言。

The mechanism of ki 11 ing the schistosomulae in vitro depending on the specific ige antibody were observed . the distribution of the protein encoded by the cloned gene was determined by immuno - electromicroscopy with protein a - colloidal gold . in order to further analyse the epitope features of the protein relevant to the specific ige antibody , the phage display library of random peptides was screened by pooled sera with the specific ige antibody 借助现行生物信息学分析手段，通过互联网进入genbank数据库，对sj43b与已知序列进行同源性比对，应用dnatoois软件对其编码蛋白序列的氨基酸纽成、亲水性、抗原性和可及性进行分析，并在blastp程序下在genbank蛋白数据库中对sj43b编码3人卞医科大学博士学杠论文蛋白进行同源性检索。
Slurry erosion tests were carried out with the manufactured test apparatus in order to study the erosion properties of the polyurethane composites . the results show that the wear resistance of silicon dioxide reinforced polyurethane composites decreased with the increased amount of particles , and the wear resistance of the alunima reinforced polyurethane composites first increased but then decreased . the wear resistance of the alunima reinforced polyurethane composites processed with kh550 coupling agent were maximum at the volume content of 15 % 试验结果表明，聚氨酯复合材料的冲蚀磨损性能随白碳黑体积分数的增大而降低，随al _ 2o _ 3颗粒体积分数的增大先升高而后降低；经过偶联剂kh550处理的al _ 2o _ 3颗粒增强复合材料耐磨性比经过kh560处理的复合材料高；经过偶联剂kh550处理的al _ 2o _ 3颗粒增强复合材料在体积分数为15时具有最佳的冲蚀磨损性能。
