在四极性交配系统中，A和B因子分别对应位于不同染色体上的两个交配型位点，两个单核菌丝相遇，只有当它们形成A1A2B1B2或者AαAβBαBβ型时，才能产生具有锁状联合的双核体，完成整个有性生活史。

Its basic idea is to realize all kinds of radio communication functions, such as work band, kinds of modulation or demodulation, data format, encrypt mode and communication protocol by upgradable and displaceable software on a hardware platform which is opening, expanded and simple structure. And it makes wideband A/D and D/A converters close to the antenna, in order to develop more flexible and opening wireless communication system.

它的基本思想是以开放的、可扩展的、结构最简的硬件为通用平台，把尽可能多的通信功能，如工作频段、调制解调类型、数据格式、加密模式、通信协议等用可升级、可替换的软件来完成，并使宽带A/D和D/A转换器尽可能地靠近天线，以研制出具有高度灵活性、开放性的新一代无线通信系统。

On average, these dually listed companies are still traded at a 30% premium in HongKong, or the H share market, over the price of the same stock in the A share market.

如果我们比较同时在国内外上市的公司的股价就能发现，这些双重上市公司在H股市场的股价比在A股市场平均要高出百分之三十，而在五年前这个数字却是百分之三百八十，显然这些上市公司的股票价格区间被压缩了，但其在A股市场的价值并不低，（这句话应该翻译为：A股市场的总体价格水平并不偏低），这些股票的价值被高估了（和海外市场比，A股市场依然被高估了）。

Homology modeling of 3-D structure of two AChE from L.entomophila were constructed using H.sapiens(1p0i:A) native BuChE structure and Drosophila melanogaster(1d×4:A) native AChE structure as templates,respectively,by SWISS-MODEL.The catalytic triad were found and denoted in the 3-D structure of AChE from L. entomophila referring to T.californica.2.2 Gene cloning ofβ-actin and mRNA expression levels of two AChE genes from L. entomophilaBecause no reference gene has ever been used in Real Time PCR for L.entomophila in GeneBank,a fragment ofβ-actin gene was cloned from L.entomophila(GenBank Accession No.: FJ041117).It consists of 822 bp encoding a protein of 273 amino acids residues.

利用蛋白质结构同源建模工具，分别以人丁酰胆碱酯酶(1p0i：A)和果蝇乙酰胆碱酯酶(1d×4：A)的蛋白晶体结构为模板，对嗜虫书虱2个AChE的三维结构进行同源建模，并在三维结构中发现了AChE的酶解活性位点，证明嗜虫书虱体内也存在2个AChE基因。2.2嗜虫书虱β-actin基因克隆及乙酰胆碱酯酶基因mRNA表达水平研究目前关于嗜虫书虱的分子生物学研究较少，在GenBank中没有可用作内参基因的序列，因此本研究从嗜虫书虱体内克隆获得β—actin基因片段(GenBank登录号：FJ041117)，该片段长度为822 bp，编码273个氨基酸残基，同源性比对分析表明该片段与其它昆虫的β—actin基因具有很高的同源性。

Results:Wound healing rate in group A was higher than that in group B and the wound healing time was 1～3 days earlier in group A.More active proliferation of epidermic cells around wounds showed in group A.The function of fibroblasts in wounds,collagen synthesis and secretion,were more vigorous in group A than those in group B.

结果：A组创面愈合率高于B组，其创面愈合时间较B组提前1～3 d；创周表皮细胞增殖也较B组活跃，创面成纤维细胞较B组呈现出更旺盛的合成与分泌胶原纤维的功能。

Within sampling depth,accumulation rate ranges from 0.02mm/a to 2.58mm/a for these sections,and a significant erosional/depositionalhiatus is identified for two natural sections.

在取样的深度范围内，所测剖面的堆积速率从0.02mm/a到2.58mm/a，并显示一般风成黄土的堆积速率要比水成堆积物的堆积速率要慢。

However, the 3 groups from medium A exhibited the highest microbial diversity and best decolorization results with 99.53% and 97.42% color removal rate of Reactive Red M-3BE and Acid Red. From them, 16 strains of fungi were isolated and primarily identified as Saprolegniaceae, Eurotiaceae, Erysiphaceae and Physodermataceae . Fungi groups from medium B and D exhibited a bit lower color removal rate of various dyes and only 3 and 2 isolates primarily classified as Saccharomycetaceae and Eurotiaceae were obtained from them. Fungi cultures in medium A and B could produce lignin peroxidase, and those in medium D could be detected higher activity of laccase. All the fungal cultures exhibited very weak activity of manganese dependant peroxidase.

来自A培养基的3组菌群显示出最好的脱色效果和最大的菌群丰富度，对50mg/L的活性红M-3BE和酸性红A溶液的脱色率最高达到99.53%和97.42%，从中分离到了16株真菌，初步鉴定分属于水霉科、曲霉科、节壶菌科和白粉菌科；而B和D培养基中所获得的菌群脱色效果稍差，从中仅得到3株和2株真菌，初步鉴定属于酵母和青霉。A、B两种培养基在各种染料存在下更易产生木质素过氧化物酶，产漆酶能力较弱，而D培养基产漆酶活性较高。

METHODS: After stimulated with Con A, T cells were treated with different concentrations of TMB-8 alone and its combination with cyclosporine A. The expression of CD69, the early marker of CD3(superscript +) T cell activation, was measured by FACS. The proliferation-related index was determined by carboxyl fluorescin diacetate succinmidyl ester flow cytometry. The cell-cycle distribution was analyzed by propidium iodide staining.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
