Based on division of regions of a typhoon and characteristic scales of physical quantities done by Anthes,sets of equations governing different parts of the typhoon are derived with scale analysis and wave energy equations for each part are obtained with the WKB method. Discussions indicated that physical factors contributing to typhoon development are unconstant in all parts of the typhoon,respectively shown as vertical changes in vorticity and tangential wind for the core and outer mid-tropospheric area,...
利用Anthes关于台风的区域划分以及物理量特征尺度的结果,采用尺度分析方法导出了台风不同区域的控制方程组,又用WKB方法得到各区的波能量方程并进行了讨论,指出影响台风发展的物理因子在各区的异同点:各区都有非定常因子;同时,台风内核及外围中层对流层的因子有涡度和切向风的垂直变化,外围边界层有热成风及其偏差,外围流出层有水平位温梯度,这些因子与重力波适当的移向相配合,可使台风能量发展,强度增大。

The results indicate that the deviation of viscosity concentration is still not acceptable for most of the pigments, although the solid content of pigment slurry is well linear with the reciprocal of the square root of viscosity. Furthermore, the slight fluctuation of solid content which is close to the viscosity concentration can cause significant variation of the low shear viscosity according to the calculation, and result in the uncredible test value of viscosity concentration.
结果表明,尽管颜料悬浮液固含量与黏度平方根倒数的线性关系相当好,但对于相当一部分颜料,由此得到的黏浓度数据偏差仍然不可接受;而且根据测算,在黏浓度点附近,固含量的微小波动会造成低剪切黏度很大的变化,导致黏浓度的测定结果不可靠。

The characteristics of image moments can be applied in manyfields. We apply Tebechbief moment characteristic to match replace of using graycharacteristic as primitives. An area moment has the property of unsensitive to transition,rotation and sealed change of area, the property of area moment is applied in the areamatching approach in our thesis, combined with a new constraint, and a novel area-basedmatching approach is proposed.

Especially, the difference of the nearest-neighbor hopping integral is due to the effect of the curvature of the carbon nanotubes. So, in fact there is a very narrow energy gap near the Fermi energy of unsquashed metallic zigzag carbon nanotubes, and, a slighter deformation is required to open a considerable energy gap in metallic zigzag carbon nanotubes than that in armchair nanotubes.

In this paper, the effects of the rigid body motions and low frequency surface errors on the image quality were analyzed. Quadratic equations were used to build the mathematical model of the Wolter type I and II X-ray telescopes and reduce the computational complexity of ray tracing. With the help of a self-developed optical surface analysis code, the effects of the perturbations of the mirrors on the image quality was analyzed and the growth of the image spot formed by deformed telescopes was calculated, this is important for giving the reasonable fabrication tolerance.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
