SCR-521. The most significant improvement in the ASE was the use of an antenna duplexer, which permitted the use of just one send-receive antenna, rather than two separate units.

ASE上最重大的改进的使用了天线双工机，使得可以只使用一个收发天线而不是两个，这使飞行时的风阻明显减少，飞行性能得到显著的提高。

SCR-521. The most significant improvement in the ASE was the useof an antenna duplexer, which permitted the use of just one send-receive antenna, rather than two separate units.This yielded appreciable improvement in aircraft performance because of drastically reduced wind drag.

All of these results prove the analysises and hypothesises described above, but it is also indicated that if the householder has a private working experience, for instance, an experience in a private enterprise, he prefers selling at the "three sale fastigiums", which differs from the analysis.

户主经历对农户选择销售时机有显著影响，与本文分析相反的是，户主拥有私人性质的工作经历使其更倾向于选择&三大销售高峰期&售粮，本文认为这是粮食主产区的特性造成的。

The achievement was notable because it used fermions, a class of atoms with a nuclear structure that makes it difficult to create a condensate.

该成果是显著的，因为它使用的fermions ，一类原子的核结构使它难以形成凝结水。

In this dissertation the"Penalty"finite element method was employed to compute the velocity of the three-dimensional flow of power-law fluid in a profile die. In order to decrease the needed computer memory and raise the stability of numerical simulation, a set of decoupled methods such as PFEM, pseudo-body force method and transformation of momentum equation to the elliptic equation was developed to establish the general finite element equations to compute the distributions of velocity and viscoelastic stress of the three-dimensional viscoelastic flow of the Phan ThienTanner fluid in a profile die. During numerical simulation of the extrudate swell of the PTT fluid, the flow in the die and out of the die was analyzed separately, which demands less computer memory.

The key techniques used in numerical simulation of the three-dimensional extrusion from dies such as decision of boundary conditions, creation of initial velocity field, selection of penalty factor, high Weissenberg number problem , regeneration of the free surface were studied in detail.

Limited slip differential is improved according to common differential. Not having the common differentials disadvantage of dividing the torque into two equal parts, limited slip differential can give most torque or even all torque to another driving wheel which is not revolving in order to make use of the friction of this driving wheel to produce enough traction. This will greatly increase the dynamical capability, the passing capability, the stability and the safety of automobiles on different friction roads. So limited slip differential is substitute for common differential.

防滑差速器是对普通差速器的革新与改进，它克服了普通差速器只能平均分配扭矩的缺点，可以使大部分甚至全部扭矩传给另外一个不滑转的驱动轮，以充分利用这一驱动轮的附着力而产生足够的牵引力，大大提高了汽车在双附着系数路面上的动力性和通过性，显著改善了汽车操纵稳定性，有效地提高了汽车行驶安全性，是普通差速器的理想替代产品。
