变异性主要表现在仪节名称、仪节的具体操作方式和某些纯地方性仪式不同，同一性表现在具有基本相同的来自道教正统的仪式结构和基本相似的地方仪式结构，显示出民间既重视在太平醮中加入地方的表达方式也重视整体仪式符号的规范性。

With some examples, the correlat ions between the thermal expansion coefficients of minerals and the types of cr ystal structures, the nature of chemical bonds, the valencies of ions , the interionic distances, the percentage ionic characters, the electronic conf igurations of ions and the chemical compositions are discussed and summarised . The crystal chemistry approach has been used in the calculation of the th ermal expansion coefficients for minerals with simple structures and composition s.

晶体化学方法是研究矿物热膨胀系数的有效方法，但由于矿物的热膨胀系数和晶体化学参数之间的定量关系尚未完全弄清，目前仅仅能对简单结构矿物的热膨胀系数进行计算，结构、成分较复杂的矿物的热膨胀系数计算尚缺乏好的晶体化学模型。

The corrugated lateral surface superlattice is one important kind of structures in such low-dimension systems and it has been possible to fabricate ultrafine periodical lateral structures and provide more adjustable structural parameters.

In fact, the total energies for the possible metastable alloy phases of A〓B and AB〓 types of six possible structures were calculated as a function of their lattice constant to find out if the respective metastable phases of A〓B or AB〓 types could be relatively stable in the selected systems. The calculation not only predicted the possible metastable states but also the lattice constant of the corresponding metastable alloy phases of either FCC or HCP structures.

The dynamic characteristics of stochastic truss structures and stochastic frame structures are analyzed by using Random Factor Method. Then, from the expressions of structural random response of the frequency domain, the computational expressions of the mean value, variance and variation coefficient of the mean square value of the structural displacement and stress response under the stationary random excitation or non-stationary random excitation are developed by means of the random variable's functional moment method and the algebra synthesis method.

考虑压电智能桁架结构物理参数、几何参数、结构阻尼和外荷载、闭环系统控制电压分别或同时为随机变量，构建了结构在随机力作用下的动力响应分析模型，提出了求解方法，推导出结构动力响应随机变量的数字特征计算表达式，通过算例验证了所建模型和所提求解方法的正确性和有效性。
