This article elaborates ( a ) the variations of linguistic structure and stylistic nuance in the process and ( b ) the linguistic factors and those of cultural background of the emerging of the variations 本文详细讨论了其间所发生的语言结构变异和语体色彩变异，并探讨了发生变异的语言因素和文化背景因素。
Research has determined that undetectable iral leels - - although not a cure - - slows iral replication to the point where the irus has less chance of mutating and deeloping resistance to the drugs 研究证实体内病毒保持在检测不出的水平尽管并不意味着痊愈，但可以将病毒的复制降低到使其不易变异和产生抗药性的程度。
There are many variations and different levels of the temporal planets as seen by different puranas and often describe the nature of the phenomenal universe in various ways which may look conflicting 不同的往世书里描写的各种暂时性的行星会有变异和不同，经常以不同的方式去描述显著的宇宙本性，看起上来是不一致的。
The results from research on the spatial - temporal variability of soil water content , spatial variability of soil water content of different layers and soil water - storage in sloping field can be showed . 1 本文对丘陵区坡地土壤水分含量的时空变异、坡面各层土壤水分特性及容重的空间变异和坡面土壤水库贮量的空间分布进行研究，得出了以下结果： 1
Part one mainly generalizes the technology of construction and style of original dwelling architecture , as well as the evolution of configuration of traditional architecture which embodies the semiotic language and art expression 第一部分归纳了早期居住建筑的构筑技术与风格，以及传统建筑形象的变异和进化，即对“符号”造型语言及艺术表现的追求。
The breakthrough has started a race against time to develop a protease inhibitor - - a treatment that could block enzymes from the severe acute respiratory syndrome coronavirus and keep it from strengthening and infecting other cells in the human body 尽快开发出一种蛋白酶成了科学家们的时间赛，这种蛋白酶能够阻止非典病毒的在人体内的变异和其他细胞的感染。
Using insights from geographical theories of cultural diffusion , mutation and adaptation , we critically interpret the circulation of knowledges of the creative economy , claims to its significance , areas of emphases and notable silences 运用地理学理论中对文化扩散、变异和适应性等问题阐述，我们批判性地解释创意经济中知识的传播和流通过程，指出其重要性、重点领域以及目前的沉寂。
Generally speaking , the real effective standard in the course of economic system evolution is , whether separate personal knowledge can be effectively used , whether social distribution of knowledge can be effectively promoted 能否有效地利用分散性的个人知识,或者说能否有效地促进知识的社会分工的发展,是不同经济制度之间竞争、变异和适应的依据,是经济制度演化进程中真正的效率标准。
On our conjecture , gene 3a , a highly conserved sequence , may be the determinant of the virulence of fmdv . changes in 3a have been associated with altered host range . a deletion in 3a has been associated with bovine attenuation of fmdv 我们根据已有资料推测， 3a基因可能是口蹄疫病毒的毒力决定簇，它具有高度保守性，其变异和部分缺失对病毒在牛体内的致弱和宿主嗜性发生改变起重要作用。
That is because only large firms have been able to afford the supercomputers needed to mutate and crossbreed large virtual genomes ? and then simulate the behaviour of their offspring ? for perhaps 20m generations before the perfect design emerges 因为只有那些大公司才能负担得起费用来使用必须由超级计算机来进行的对大型虚拟染色体进行变异和杂交- -以及随后对这些染色体后代行为模拟- -在完美的设计浮现之前，可能需要经历2000万代。
