Meaning that it consists of a proteinaceous core particle that has the viral genome inside of it in the form of double stranded DNA.

这意味着它由一种蛋白质核心颗粒病毒基因组内有它的形式双链脱氧核糖核酸。

7Kb of these isolates were amplified by using RT-PCR The amplified DNA were then cloned and sequenced The analysis of the sequence data further confirmed that IBV was the pathogenic agent of the infectious disease associated with proventricular lesion

利用扩增片段两端的EcoRⅠ和BamHⅠ位点将扩增片段克隆进pBluescripⅡKS载体，转化大肠杆菌JM109，挑选白色菌落并用PCR方法对插入片段进行鉴定。用双脱氧终止法对扩增的片段进行测序并与GenBank公开的序列进行比较分析。结果进一步证实IBV是导致此种野外发生的腺胃相关疾病的病原。

In this investigation, we have studied the structures of the impurities generated along with methamphetamine using this route from pseudoephedrine.

在实验中我们还研究了通过伪麻黄素这条路径合成脱氧麻黄碱的同时所产生的杂质的结构。

Methods:Cardiac muscle of twoday neonate rattus was digested repeatedly by 0.0625% trypsin.The cardiocytes were collected in DMEM medium,which contains 10% fetal bovine serum.Myocardial cells were isolated with the technique of differential anchoring velocity with 90 min and were pured by Brdu.The cardiocytes were placed into CO2 incubator to incubate seven days after their purification.

应用0.0625%的胰蛋白酶重复消化出生第2 d乳鼠的心肌组织多次，收集的细胞用含10%胎牛血清的DMEM培养基中和，用差速贴壁分离法分离，在以溴脱氧尿嘧啶纯化心肌细胞后置CO2培养箱孵育7 d。

The reoxidation mechanisms of IF steel containing Al and Ti by reducible oxides in the slag were analyzed. A model of predicting total oxygen in the molten steel was established based on the reoxidation mechanisms. It was found that two different reaction mechanisms existed when and in the slag reoxidated the molten steel.

分析了IF钢冶炼过程中渣对钢液中、的氧化机理，在此基础上提出了IF钢加铝脱氧后全氧的预测模型结果表明，熔渣中、对钢液的二次氧化存在两种方式。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
