Results show that the field amplitude and S parameter decrease with the oblique misalignment angle increase.

结果表明：随着倾斜偏心度的逐渐增大，倾斜偏心同轴波导的S21参数和电场的幅值减小，但减小的幅度不是很明显，不会影响同轴波导的正常工作。

This thesis focus on GPS application in magnetic suspension engineering:① the formulation of oblique cylindrical projection is worked out according to characteristics of long distance precise engineering and map projection theory. The author has developed an application to accomplish coordinate conversion from generally used coordinate systems to oblique Maglev Coordinates System.② considering not only project peculiarities but also position of control points, selection of initial points, connection type, selection of repeat baseline and ground observed quantities, GPS network is designed on electronic map and we may extract GPS network information by program developed using Visual Basic 6.0 while the results are stored in control point file and baseline vector file.③estimate accuracy of various GPS networks designed on electronic map by method of 2D restriction adjustment. GPS network simulation design and accuracy estimate come true.④Predominate the rules how connection type , repeat baseline and precise baseline of range finder influence GPS network precision through comparing accuracy of various GPS network. Thereby, the solution how to establish GPS network in long distance precise engineering is figured out.

It was found greater expression of NRP2-1 and NRP2-2 in pituitary, ovary, uterus and oviduct of ruttish Erhualian than corresponding tissues of ruttish Duroc, which suggested enhancing expression of NRP2 was favorable to increasing litter size. But the difference of NRP2 expression was not significant between two breeds, which suggested the key phase that NRP2 affected litter size was not oestrum probably, or NRP2 could enlarge cell signals and finally affect litter size ascribe that it was the receptor of nerve axon guidance factors.

NRP2-1和NRP2-2在发情期二花脸卵巢、子宫、输卵管中的表达量均大于杜洛克相应组织的表达量，推测NRP2表达水平高可能有利于提高产仔数，但两品种间表达差异不明显，推测NRP2影响产仔数的关键阶段可能不是猪的发情期；另外，NRP2 是神经轴突介导因子的受体，这些神经轴突转导的信号往往有级联放大的功能，虽然NRP2-1和NRP2-2在二花脸和杜洛克卵巢、子宫、输卵管中的表达差异不大，但二花脸有可能通过神经系统转导信号的级联放大最终引起一些效应激素或蛋白的急剧增加，从而提高排卵率或产仔数。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
