To tackle this problem within the continuum mechanics approach, one should establish new mechanics models, and further, use molecular dynamics simulation or other experimental to give reasonable verifications and supplements to the theory.

运用连续介质力学方法研究此类问题，首先需要建立新的力学模型；此外，还应当运用分子动力学（molecular dynamics，简称MD）模拟技术或者其他实验手段来对理论进行合理的检验及补充。

The density matrix formalism in quantum mechanics, and quantum statistical mechanics.

量子力学的密度矩阵形式，以及量子统计力学。

We get the vary rules of mechanics character, study the dilatability and fractal characters of shear surface, analyzed the distortion manner of different kinds mixture, we build the forecast model though test results, while the results are generally same by different test ,so we can use the model to preestimate the mechanics index of mixture quickly.

本文通过试验研究了土石混合料力学特性随岩性、含石量、密实度及颗粒最大粒径等影响因素的变化规律，分析了土石混合料的剪胀性能、剪切面的起伏特征和分形特征、土石混合料的剪切变形破坏方式，经比较现场试验、室内试验及数值模拟的结果基本一致，并依据试验结果建立了不同类别土石混合料力学特性指标的预测模型，可通过模型快速预测不同类型土石混合料的力学特性指标。

In this paper,author's research starts from the thermal expansivity and thermal transmission theory in physics,then utilizes the thermo elastic theory in mechanics of elastic bodies and the solution of statically indeterminate system in mechanics of materials as well as the interaction principle between soil and elastic body,finally gets the correct thermal stress analysis formulae of shaft-wall.

长期以来，在基岩段井壁结构的设计中，一直将地压作为结构设计的影响因素，实际上是不完善的；对于煤矿的进风井，井壁的温度随季节而变，因此，温度因素同样的应该考虑到井壁结构的设计中去；因此，将遗漏的因素补充入传统的设计理论中，是目前十分紧要的一项研究工作。

Comparisons between market performance under auction mechanisms and that under market maker mechanisms are made in terms of liquidity, stability, efficiency and transparency. The comparative results show that certain price formation mechanics integrated with specific market environment can affect market performance. The results of the test that is used to verify the liquidity of security market in China indicate that current price formation mechanics can provide the securities market with better liquidity. But the fixation of the minimum changing price lowers the liquidity of the market factitiously and close call auction mechanisms result in increased price fluctuation and price manipulation. Through the analysis on the competitive strategy of securities market, the objects and principles of the design of price formation mechanisms are established.

本文推导出了竞价机制和市商机制下证券市场的均衡价格，结果表明不同的价格形成机制对资产的真实价格有着不同的反映；从证券市场的流动性、稳定性、有效性和透明度等四个方面分别对竞价机制和做市商机制下的市场绩效进行了比较分析，结果表明一定的价格形成机制和特定的市场环境相结合就会对市场绩效产生不同的影响；通过对我国证券市场的流动性进行实证检验，发现当前我国证券市场价格形成机制能够为市场提供较好的流动性，但固定的最小变动价位人为地降低了市场流动性，并且封闭式的开盘集合竞价导致价格波动加大和市场操纵。

An alternative formulation of quantum mechanics is Feynman's path integral formulation, in which a quantum-mechanical amplitude is considered as a sum over histories between initial and final states; this is the quantum-mechanical counterpart of action principles in classical mechanics.

一个量子力学的代用公式是费曼路径积分公式，在其中量子力学振幅被认为是超过最初与最后态历史的总和；这就是在经典力学里量子力学作用原理的相似物。

Computational fluid mechanics is an important course in the field of fluid mechanics at the contemporary era.

计算流体力学是当代流体力学领域的一门重要课程。

The method of analytical mechanics is mainly to establish a degree of freedom for the mechanical system,to choose generalized coordinates,to work out the energy or concerned quantities of the system,to introduce the equation or principle formulain analytical mechanics, and to then find the solution.

分析力学方法主要是确定体系的自由度，选取广义坐标，求出体系能量或有关物理量，代入分析力学中的方程式或原理式，计算求解。
