使变异

A second bug experienced a mutation that allowed it to make use of the acetate excreted from the first.

第二个细菌经历的变异使它能够利用第一个细菌分泌出来的醋酸盐。

Hilleman was also the first to identify how the influenza virus mutates, and he virtually single-handedly spearheaded creation of the vaccine that prevented the Asian flu outbreak of 1957 from becoming a repeat of the 1918 Spanish flu pandemic, which killed 20 million people worldwide.

希勒曼也是确认流感病毒是如何变异的第一人。事实上，他独自一人率先研制出流感疫苗，从而避免了1957年爆发的亚洲流感重蹈1918年西班牙流感疫情的覆辙，而1918年的疫情使全世界2000万人死亡。

Darwin's barnacle studies convinced him that variation arose constantly and not just in response to changed circumstances. In 1854, he completed the last part of his Beagle-related writing and began working full-time on evolution.

达尔文的藤壶研究使他确信变异不断地出现，而且不仅仅是针对变化的环境。1854年，他完成了小猎犬号考察相关写作的最后一部分，开始用全部时间研究进化。

The investigation shows that the local authorities only implement, but rarely make policies in the policy system; county being the main body only means the loan economy with the transfer payment lacking the amount; the system of separation between fiscal right and affairs right makes it difficult for people to find out who should be responsible for the educational funds which is contradictable to what is stated on the document.

调查发现，在政策规制中地方政府只有执行而很少决策，"以县为主"只是借贷经济而已，转移支付并没有定数，而"财权事权分离"的制度使公众寻找不到教育经费的责任人，这与纸面上说得通的文件是不一样的；然而地方真实的行政系统却充满了积极的精神，正是"政策变异"的作法维持了穷国办大教育的奇迹，但其中也埋伏着失却法理程序的潜在危险。

By probing into the different phenomena caused by schema difference and schema...

通过分析译者在翻译过程中由于图式的差异及变异造成的各种问题，作者指出译者在翻译过程中要充分激活相关图式，同时不断充实自身不同文化的背景知识，了解不同文化中的图式差异，并采用有效的方法激活译文读者的图式，使译文达到与原文相似的效果。

The results showed that there existed variation among eucalypt families in wood physical-mechanical properties and wood chemistry. There were significant differences among E.pellita families、E.grandis families and E.urophylla譋.grandis clones in wood colors as well as between Strains and within trees.The variation of the surface wetability of wood between E.grandis families and E.urophylla譋.grandis clones were significant.Even in the same families level or clones level,there still existed the same regulation. The degree of collapse of eucalypt had a large relation in the amount of tylosis in vessel and vestured pits on the cell wall of vessel. The more rich tylosis and vestured pits in vessels,the more probability to occur collapse for eucalypt.The biggest moment collapse was probably the critical point of the drying degrade.During the fomulation of drying technology,it is necessary to adopt moderate condition to make the vessels which had formed the biggest moment collapse at the biggest moment collapse resume,especially to prevent the permanent set.At the normal temperature level,the main factors which influenced residual collapse were the contents of ray parenchyma and axial parenchyma .Nearly all the cells joined the course of forming the moment collapse and biggest moment collapse.Interval drying was fit for eucalypt plantation which was easier to make collapse.

研究表明：桉树不同家系间木材物理力学性质和化学组成存在差异；粗皮桉家系间、巨桉家系间、尾巨桉无性系间材色存在显著差异，株间、株内木材材色存在变异；桉树木材表面润湿性在巨桉家系间、尾巨桉无性系间存在着显著差异，在同一家系或同一无性系中，株间和株内也存在着相同的变化规律；桉材皱缩程度与其导管中侵填体的多少和导管壁上纹孔具有的附物多少密切相关，侵填体含物越丰富，纹孔附物越多，桉材越容易皱缩；最大瞬间皱缩是能产生更大干燥降等的临界点，在制定干燥工艺时，必须在最大瞬间皱缩发生时，采用温和条件，使已产生最大瞬间皱缩的细胞尽可能多的恢复，尤其不能使其产生永久变定；在常温条件下，影响残余皱缩的主要因子是射线薄壁细胞和轴向薄壁细胞含量；而对于瞬间皱缩和最大瞬间皱缩，几乎所有细胞都参与它们的形成过程；对于易皱缩的桉树木材，间歇干燥是最有前途的干燥方法。

Then by mutating that one gene, the sum of genes in the string would increase or decrease.

因此，使那一个基因产生变异就可以使一连串基因的总数增加或减少。

Then by mutating that one gene, the sum of genes in the string would increase or decrease.

因此，只要使那一个基因产生变异，就可以使链中基因的总数增加或减少。

Individuals with gene variants or haplotypes associated with low levels of dopamine beta-hydroxylase were more likely to attain cocaine-free urine with disulfiram in a study of heavy users of cocaine.

试验中投予disulfiram的严重古柯碱成瘾患者，如因个体基因变异或基因序列单体变异使体内产生较低的多巴胺贝他水解酵素，较容易得到没有古柯碱的尿液。

Due to the restriction from social environment and psychology of public language and the inter-restriction between pursuing dialect brink and seeking dialect protection, Hankou dialect variation is on the state of relatively steady sitzkrieg. Without tremendous force from society, it is difficult to expand social distribution of Hankou dialect words variation.

由于社会环境及公众语言心理等因素制约，追求方言边缘化和寻求方言保护的两种语言心态相互牵制，使汉口话变异处在相对稳定的胶着状态之中，如果没有来自社会的强大力量推动，扩展汉口话词语变异的社会分布便不容易。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
