This paper presents the portfolio selection problem of two-attribute money and creates a model of portfolio selection based on two-attribute money, which can both contain the existing portfolio models and overcome the above-mentioned deficiencies. A series of new concepts is put forward, such as, holding wealth, obtainable wealth, short-term utility function, short-term expectation-variance utility function, state-expectation-variance utility function, short-term expectation-variance utility curve, long-term expectation-variance utility curve, margin utility contribution force, additional contribution force, profit-risk exchange rate and optimal portfolio expansion curve; The state-expectation-variance analytical method is developed from the expectation-variance analytical method; A set of systematic theories concerning two-attribute portfolio selection is thus established.

You can play with two central mid fielders, two wingers and two strikers and still create a third attacking line with movement of other people so if a winger comes inside he can work in between lines and the full back goes forward.

你可以让两名中场、两名边锋和两名前锋一起上场，而且你还可以通过其他队员的跑动创造出第三条的进攻线。所以如果一名边锋内切的话，他可以在两条线之间进攻，同时后卫线也可以前移。

You can play with two central mid fielders, two wingers and two strikers and still create a third attacking line with movement of other people so if a winger comes inside he can work in between lines and the full back goes forward.

当你使用两个中前卫，两个边路和两名射手时，通过其他球员的运动一样可以创造出第三条攻击线。如果一个边锋内切，那么他将会在两条线之间活动并吸引后卫向前移动。

The nucleotides sequence and deduced amino acid sequence of these cDNA figments mentioned above were divided into two fractions. One is carbon part of L gene , the other is 5 terminal,and they were compared with other rabies-related virus strains published in NCBI previously.The result show that the homology of nucleotide sequence and amino acid sequence of carbon part in L gene among these two rabies virus strains is 91.3% and 95.8%, and these two strains belong to type of gene I.

本实验以吉林鹿源DRV8202株及河南鼠源野毒株MRV的L基因的C端为主要研究内容，用RT-PCR和3'-RACE方法对其进行了克隆和测序，将所测得的核苷酸序列和推导的氨基酸序列分成两个部分，一是L基因C端序列，另一个是L基因5'端的非编码区，并与NCBI上公开发表的狂犬病毒其它毒株的相应片段进行分析比较。

Chen Pei: The search in these two years passes first-rately, the tide that I think to leave generation is the service of personalized technology and personification, discuss future when you, state you can provide corresponding service, our product still has a lot of inadequacy, two this years so we make shut close two years, basically express main point of view no longer, because I had been told, and what I think I look is right, the in letting namely search that I should do has his product and technology, this is opposite especially a lot of technology companies, he must turn his technology into the product that an user can feel, this needs time and training.

陈沛：这两年中搜过得非常好，我认为下一代的浪潮是个性化的技术和个人化的服务，当你探讨未来，表示你能提供相应的服务，我们的产品还有很多的不足，所以这两年我们叫闭关两年，基本上不再发表主要观点，因为我已经讲过了，而且我认为我看的是对的，我要做的就是让中搜有自己的产品和技术，这个特别是对很多的技术公司，他必须把自己的技术变成一个用户可以感知的产品，这个是需要时间和磨炼的。

The polymer features with two kinds of zinc centers: one is hexa-coordinated by four water ligands, two oxygen atoms of two formates and the other is coordinated by six oxygen atoms of six formates.

This allows two-line printing at the speed of a single line, or four-line printing at the speed of two lines, thanks to an innovative dual nozzle printing system using two streams of independently deflected ink, rather than a single ink jet.

这允许在一个单一的线路，或四速线在两线高速打印两行打印，以创新的双喷嘴的打印系统使用两种独立偏转的流墨，而不是一个单一的喷墨感谢。

Additionally, you should adjust the spacing between the "two", when the book block through fixed plate and activities-boards, rooms, with a slight resistance, milling cutter head back to work, it will not be due to the "two" spacing adjustment is too large to make the book block milling back friction cause occurs fibrillation an edge on the corresponding wear and tear of the medial two Launchpad, which is to ensure that quality milling back to prevent back milling deformation to make the package this consistent instructions.

此外，还应调整好&两板&间距，当书芯通过固定板与活动护板间时，略感有轻微阻力为度，铣背刀盘工作时，就不致于因&两板&间距调得太大，使书芯铣背发生颤动摩擦导致刀口对应的&两板&内侧磨损，这也是保证铣背质量，防止书背铣削变形，促使包本质量稳定的操作要领。

The simulation results shows that when the hydroforming for real axle housing needs two bulge processes and the specific value of the two bulge ratio is about 1, the result is the best one; To obtain an appropriate route of loading force need adjust internal pressure and axial compression force for many times and according to the failure, the size of the two forces which has been mentioned can be rapidly and rationally adjusted; Because of good greasing conditions influencing largely, reducing the friction between tube blank and die inside surface as well as possibly not only makes more materials flow into the bulge area but effectively diminishes the axial compression force; The good or bad characteristics of tube blank material is also one of the decisive factors and when material is selected, we first consider its' formability.

模拟结果表明，当后桥壳需要两次进行胀形，两次胀形比比值约等于1时，胀形结果最好；合适的加载路径要经过多次调试，能根据胀形缺陷对内压力和轴向力的大小进行迅速地合理调整；良好的润滑环境对后桥壳液压胀形的影响巨大，要尽量减小管坯与模腔内壁的摩擦力，不但使更多的材料流入胀形区，而且能有效的降低轴向力的大小；管坯材料性能的好坏也是影响胀形的决定性因素，选材时首先要考虑材料的成形性。

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