着重介绍了剖分T型钢这种新型材料的研究现状，并对比关于T型钢腹板宽厚比限值的三种不同的理论观点，对三种观点进行了分析，使单轴对称截面压杆设计中比较复杂的弯扭屈曲问题得到有效的处理，从而使设计工作得以简化。

Irwin Barr of AAI Corporation introduced a series of flechette weapons, starting with a shotgun shell containing 32 darts and ending with single-round flechette "rifles".

AAI公司的Irwin Barr提出了一系列的飞镖武器。第一种是装配32支镖的霰弹枪而最后一种是单发飞镖的步枪。斯普林菲尔德兵工厂和温彻斯特连发武器公司生产了多枪管的武器。

The multiple alignment and phylogenetic analysis demonstrated that each genewas a member of a multigene family. 3. The function of 3GT gene was confirmed by Agrobacterium-mediatedtransformation of arabidopsis thaliana. Arabidopsis thaliana was transformed by floral dip method with AgrobacteriumGV3101 carrying expression vector pG3GT. Four transformants were selected for theirgrowth ability on 1/2MS medium containing 50mg/L kanamycin.

马铃薯野生种3GT基因的功能验证为了验证马铃薯野生种3GT基因的功能，构建带CaMV 35S启动子的表达载体pG3GT，转化农杆菌GV3101，用茵液浸泡花序法对拟南芥进行遗传转化，在含50mg／LKan的1／2MS培养基上筛选，得到4个抗性幼苗，转化率为0.13％，对移栽成活的3株进行PCR检测为阳性，Southern blot分析2株表现为阳性并为单拷贝整合。

Mutation rate at exon of GH in five bovine species was very low with the percentage of 3.48%. The majority of nucleotide substitution was nonsense mutation and only one missense mutation was observed. Molecule tree based on haplotypes of bGH at exon 5 showed that differentiation was apparent relatively between Bubalus bubalis and Bos taurus, Bos indicus, Bos grunniens, Bos frontalis. There was no apparent differentiation among other four bovine species and they shared mutual ancestral sequence.

序列分析表明，5个牛种GH基因外显子5的遗传变异水平较低，平均核苷酸变异率约为3.48%，而且绝大多数位点的核苷酸替换是同义突变，仅发现1个错义突变位点；从GH基因外显子5序列单倍型构建的分子进化树来看，水牛与普通牛、瘤牛、牦牛及大额牛的分化相对比较明显，其他4个牛种之间并无明显分化，还享有共同的祖先序列。

By means of interconnecting some such units, a fully interconnected network that has complex chaotic feature is proposed.

在上面两种方法的基础上，我们又提出一种以具有单映射特征的神经网络作为混沌单元，由多个这样的单元构成的具有复杂混沌特征的全互连网络。

In order to select monomer of Chinese herbal polysaccharide with better immunity, four CHPs, APS, ABPS, IRPS and DOPS at six doses were added in the splenic lymphocyte of chick in vitro, and cultured 48 h. The splenic lymphocyte proliferation was determined with the MTT method.

为了筛选免疫增强作用较好的单味中药成分，将6种浓度的黄芪多糖、牛膝多糖、板蓝根多糖、山药多糖等4种中药多糖分别加入到体外培养的鸡脾脏淋巴细胞中，培养48h后，用MTT法测定淋巴细胞增殖的变化。

Unlike any other wine carton currently available, Amcor's new VinPorter corrugated carton uses a patented one-piece design and perforation system to rapidly and safely transform into a branded six-bottle consumer carry pack.

与目前使用的任何其它的葡萄酒纸板箱不同，Amcor 公司新的瓦楞纸板箱采用一种专利单片设计和穿孔系统，可快速和安全地形成一种打有烙印的用户便携式 6 连瓶包装。

The specificity of hydrogen ion catalysts, for example, is very broad, whereas many enzymes perform only a single function, such as hydrolysis of a single bond or bond type.

例如，氢离子催化剂的催化范围特性很宽，反之，许多酶执行的只是单一的功能，譬如一种单键或一种键型的水解。

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。
