An approximate formula of the deflection of a local damaged plate is given and can be realized to identify the damaged amount and locality. As an example, the damaged quadrangular plate with quadrilateral simple hinged restrain is analyzed and is given an analogous formula of its deflection.

另外，用有限元结构分析软件对含损伤的四边简支板进行计算的基础上，提出了一种带损伤板的位移等效模型，可以将对损伤位置及损伤程度的物性识别问题转变成对载荷大小及作用位置的构造识别问题进行处理，从而降低识别问题的非线性程度，提高识别能力，简化识别计算。

The calculation of degree-day is usually based on the definiation of basic temperature and average temperature in the day. The basic temperature is often calculated according to energy supply, physiological demand of human body, the level of economic development and the character of temperature changes. There are mainly four methods for the calculation of average day temperature. The most popular way is to get the average of the highest temperature and the lowest one.

度日计算的前提是基础温度和日平均温度的确定，其中基础温度往往是根据能源供应、人体生理需求、经济水平以及温度变化特点而人为规定的，也有一些学者尝试用数学方法求得；日平均温度的计算方法主要有4种，国外学者经常采用的是取日最高气温和最低气温算术平均值的方法。

We fit the anisotropic interaction potential based on the Murrell-Sorbie potential function for He-HCl system by applying the interaction energy data, which are calculated at the theoretical level of the single and double excitation coupled-cluster method with noniteractive perturbation treatment of triple excitation CCSD. The new potential model is compared with other potential models. The differential scattering cross sections for collisions between He atoms and HCl molecules are calculated by using CC (Close-Coupling) method. Furthermore, the changing regularity of the inelastic differential scattering cross sections is summed up.

Based on the data collected from 8 plots and using Shannon and Simpson index, this paper calculated and analyzed diversity of Eupatorium catarium community in Hainan. And, niche breadth and niche overlap of E. catarium community were analyzed by using Levins and Pianka formulae. The results were as follows:(1)The diversity of E.

So while, within a certain range, computational processes are independent of the hardware they run on (one machine can emulate anything another can), there are real limits to the fungibility of processes.

那么当处于某一特定的范围内，计算的过程独立于它们赖以进行计算的硬件（一台机器可以仿效另一台机器能做的一切），而过程的可替代性有真实的限制。

First of all, the report introduced evolution, achievments and problems in the study of anisotropy in the inner of earth. The first-order hyperbolic system of equations is work out, which is used to describe the wave motion in 2D transversely isotropic media. Utilizing the characteristics of free-divergence, We have imposed MacCormack theme that is used to simulate multicomponent records in anisotropic media and have developed a fast high order vectorized finite-difference algorithm adapted for the vector supercomputer.

Consider for example a program that is specified as only having to work with values in the range 0 to 25000; a programmer might reasonably choose to use two-byte integers to represent such values. However, a calculation like "work out 85% of 24760" could cause problems, even though the result (21046) is in range. If the calculation is done by multiplying 85 and 24760, the intermediate result 2104600 is out of range.

考虑一个例子：一个程序被详说明其所处理的数值的范围是0—25000，一个编程者可能选择2-字节整数来表现这个值，然而，一个如，"算出24760的85%是多少"的计算可能产生问题，即使结果（21046）在范围之内，因为如果计算的过程中需要用85乘以24760，那么这个中间值——2104600超出了2-字节整数的范围。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
