As applications, the 2nd elastic moduli are used to explain the effect of chiral angle on asymmetry behavior of torsion, and finite deformation problems of single-walled carbon nanotubes are successfully simulated by the thin shell model.

作为应用：利用面内的2阶模量解释了纳米管螺旋角相关的力学行为：扭转不对称现象。利用薄壳模型成功模拟了单壁纳米管的大变形弹性失稳行为。

Theoretical calculations show that the angular distribution of the forward and backward products is roughly symmetric for the title reaction.

理论计算的结果发现，这个反应体系的前向和后向的角分布基本是对称的。

This thesis introduces the research history of sonoluminescence, the properties and equipments of single-bubble sonoluminescence and the factors affecting the amount of light emission. Based on the experimental realization of SBSL, the experiment in this thesis is to confirm the coherence between the emitting frequency and the driving cycle of SL. Under this feature ,we established the programme of the experiment that measure the angular correlations in SBSL , built the experimental devices and conducted initial measurements .Then we got the conclusion that there is a presence of non-spherical symmetry in the process of SBSL .

本文介绍了声致发光的发展历史，对单泡发光的特性和实现声致发光的设备进行了描述，对影响发光强度的要素做了概述；并在实现单泡声致发光的基础上通过实验验证了单泡声致发光的发光频率与驱动超声频率具有一致性的特点，根据这一特点确立了声致发光角分布测量的实验方案，建立了实验装置，并进行了初步测量，得到在声致发光的过程中存在着非球形对称状态的结论。

The angular velocity of the line of sight and the lead speed of the missile.

找出了引起不对称现象的两个主要原因——视线旋转角速度和导弹的前置速度。

The early introduction of many new furniture or a large number of manufacturing, the use of color and soft furniture, decorative fabrics, patterns, including asymmetric disconnected curves, flowers, twisted vortex ornaments, shells, the Chinese-style decorative arts, musical instruments (violin, horn angle system, drum), a symbol of love, wreaths, shepherd scenes booty ornaments (Battle of the decorative layout of the symbol), flower and animal.

许多新的家具或制造大量早日推出，色彩和软家具，装饰面料，图案，包括非对称曲线断开，花卉，扭曲涡饰品，贝壳，中国式的装饰艺术，乐器使用(小提琴，喇叭角系统，鼓)是爱情的象征，花圈，战利品饰品，花卉和动物牧羊人的场面。

It is true that he used the old patterns all his life with dogged conservatism (another Sansculotte characteristic, by the way); but the imposed on them such an overwhelming charge of human energy and passion, including that highest passion which accompanies thought, and reduces the passion of the physical appetites to mere animalism, that he not only played Old Harry with their symmetry but often made it impossible to notice that there was any pattern at all beneath the storm of emotion.

不错，他一生非常保守地（顺便说一句，这也是激进共和主义者的特点）使用着旧的乐式；但是他加给它们以惊人的活力和激情，包括产生于思想高度的那种最高的激情，使得产生于感觉的激情显得仅仅是感官上的享受，于是他不仅打乱了旧乐式的对称，而且常常使人听不出在感情的风暴之下竟还有什么样式存在着了。

Results showed that expansion coefficient exhibited anomalous behaviours, which at the -80℃ transition phase point temperature that are caused by Jahn Teller of "Ti—Ba—Ti—"on Barium Titanate, at same time, we also discussed that dielectric constant affected by the rate of vacancy on barium titanate.

结果表明在钛酸钡的三个相变温度点（120℃、8℃、－80℃）处，热膨胀系数反常变化，我们认为相变温度为－80℃处的热膨胀反常是因钛酸钡BaTiO3中对称元"Ti—Ba—Ti"的静态畸变造成。同时本文讨论了BaTiO3中空隙对其介电常数的影响。

The reason for credit rating becoming the core of credit system and culture of trust of securities market is that information asymmetric goes along with information fault, which keeps credit rating operating in the construction of credit system and culture of trust as a risk measurement, examiner, anticipator, and integration.

资信评估之所以成为证券市场信用制度和诚信文化的核心，是因为在信息不对称的同时，存在信息的缺陷，使得资信评估可以在证券市场的信用制度和诚信文化建设中发挥风险度量、检测、预警和整合的作用。
