In the simulation, the flow rule of melt metal in mold of horizontal continuous casting with electromagnetic stirring is measured using ultrasonic Doppler velometer, and the result is inter confirmed with the solidification characteristics is tics of zinc cupronickel thin slab in industrial product, some advantageous results are obtained that, when the current is 400 A the inner micro-pores disappear, when the current is 500 A the center equiaxed crystal layers occur and when the current is to 800 A the inner-segregation decreases to zero.

在模拟实验中，用超声波多普勒测速仪测量该电磁搅拌下水平连铸结晶器内金属液的流动规律，并与生产实验中锌白铜板带的凝固特征相互印证，发现搅拌电流达到400 A时，板带内部气孔消失，电流达到500 A时板带出现等轴晶带，电流达到800 A时板带坯偏析率趋于零。

If this is your first time trying to work at home you will need someone to help you out so you can get over the whats next syndrome, and move on to the next level.

如果这是您第一次尝试在家里工作，你需要有人帮你做出来你可以在下次whats症候群，并进入下水平。

These experimental results are useful for the practical engineering and analysis of PCC piles in the same areas.

试验结果可为今后类似土层下水平受荷PCC桩的设计与研究提供参考。

The RAPD results illustrate that the phylogenetic relationship betweenBothriocephalid tapeworm parasitic in Grass carpCtenopharyngodon idellus(C.et V.and Common carp(Cyprinus carpio L.)from different regions ofChina is infraspecific with noticeable variance bwtween them.Thephylogenetic trees based on the 3 sequences analyses above are constructed,which show the following relationships:Bothriocephalid tapeworms fromGrass carp,Common carp and Luciobrama are found to be monophyletic,and are very close to Bothriocephalus opsariichthydis,but are divergent toanother monophyletic group comprising Bothriocephalid tapeworms fromZacco,Hemiculter and Leuciscus.On the basis of phylogenetic reconstruction,autapomorphic species conceptis used in species delimitation suitablefor determining four species in the present study:B.acheilognathi,B.opsariichthydis,and two other bothriocephalids parasitic respectively inHemiculter and Leuciscus.It is also deduced that the differentiation time ofBothriocephalid tapeworms parasitic in cyprinids is earlier than that of theirhosts,and the most recent specification happened about one million yearsago.Key words Bothriocephalid tapeworm Molecular Systematics

具体成果有：通过RAPD分析探明了我国不同地理分布的草、鲤鱼头槽绦虫的亲缘关系属于种下水平，并存在较高变异；通过基因合并分析重建头槽绦虫的系统发育关系，表明草鱼、鲤鱼及鯮鱼头槽绦虫是单系群，它们与马口鱼头槽绦虫亲缘关系较近，而与〓条、宽鳍鱲及雅罗鱼头槽绦虫构成的另一单系群亲缘关系较远；在此基础上，提出符合头槽绦虫种的界定的独征物种概念，据此确定鲤科鱼类寄生头槽绦虫的四个种：鱊头槽绦虫，马口鱼头槽绦虫，以及另两种分别寄生于〓条和雅罗鱼的头槽绦虫：根据上述研究推断鲤科鱼类寄生头槽绦虫的分化年代早于其宿主，最近的一次物种形成距今约一百万年左右。

It has been found recently that the toxin gene ctxAB is carried by the lysogenic bacteriophage CTXΦ. The possibility in theory exists that the vaccine strain could reacquire ctxAB from a wild-type strain in the intestine or in the environment by horizontal transfer of CTXΦ.

但是，毒素基因ctxAB由溶原性噬菌体CTXΦ携带，可能在偶尔的情况下水平转移给减毒活菌苗，给其在现场应用的安全性带来了重大隐患。
