Objective Our objective is to study the pathogenicity of the single HGV infection.

目的 探讨单由庚型肝炎病毒感染对肝脏的致病性。

Discussed the mechanism of macromolecule permeation pellicle. Researched the characteristics and its important effect on gas monitoring of SnO2-majored N type semiconductor gas sensitivity elements.

着重探讨了高分子透气膜的透气机理，研究了以SnO2为主的N型半导体气敏元件的特点及其对气体检测所起的重要作用，给出了单片微机系统的软硬件设计。

Location-inventory system integrated design problem under stochastic demand The location-inventory distribution system design problem involving one supplier, candidate distribution centers and multiple retailers under normal distribution demand is studied in the background of building materials industry. Retailers adopt periodic reviewinventory policy, while distribution centers adopt continuous reviewinventory policy. Considering the trade-off between inventory cost, shipping cost and facility location cost, the integrated 2-echelon inventory control policies with incapacitated facility location model is presented.

随机客户需求下的选址-库存集成问题研究：以满足正态分布客户需求的型材配送物流为研究背景，研究了由单供应商、候选分拨中心和分销点构成的配送物流系统集成规划问题，分销点、分拨中心分别采用周期检查和连续检查库存控制策略，综合考虑库存成本、运输成本和设施成本之间的均衡关系，建立了二级库存控制策略与无能力约束选址集成规划模型。

In the second section, some analyses for large time behavior of the solutions of the models of scalar equation for reactors with periodic flow reversal are given by the maximum norm estimation of parabolic equations.

利用抛物型方程的最大模估计证明了单方程模型当关于单调递减时其对应的循环定态解的存在性，并且当时，模型解会趋于其对应的循环定态解。

Objective:To analyse the treatment of chronic B type hepatitis with traditional Chinese medicine pharmaceutic Yigansan combined Arabinosydenosine monophosohate.

目的 ：对中药制剂乙肝散联合单磷酸阿糖腺苷治疗慢性乙型肝炎进行临床分析。

The Mn is coordinated by four carbonyl O atoms from the DMF molecules and two phenolate O atoms of the picrate anions, forming a distorted octahedral structure.

在不对称单胞中存在着两种配位环境相同的Mn离子，四个DMF中的羰基氧原子和两个苦味酸根离子中的酚氧原子直接和Mn离子配位，形成了一个扭曲的八面体几何构型。

The lifetime of M intermediate of BRE194Q was less than 1.0 s by photomicrography. The lifetime of M intermediates of BRI119T/T121S/A126T and BRI119T/T121S/A126T/E194Q were 3.0 s and 2.0 s, respectively.

显微视频录像技术记录的PVA膜中样品的M态寿命表明，野生型BR的M态寿命最短，单突变体的M态寿命小于1.0 s，三突变体的寿命为3.0 s，四突变体的寿命为2.0 s。

The lifetime of M intermediate of the three mutants in PVA films were recorded by employing photomicrography. In distilled water, the visible absorption maximum of BRI119T/T121S/A126T and BRI119T/T121S/A126T/E194Q mutants were blue shifted notably by 11 and 12 nm respectively and the BRE194Q's was weakly red shifted in comparison with WT-BR.

与野生型BR相比较，在水溶液中，单突变体的可见吸收光谱的最大吸收峰发生了轻微红移，三突变体和四突变体的最大吸收峰则分别发生了11.0和12.0 nm的明显蓝移。

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。
