So, in this paper, a circular cavity witha large radius is used to replace the straight boundary of thehalf space, then the half space problem can be changed tothe scattering problem of two circular cavities to the steadyincident P-wave . Having the aid of the mature cylinderfunction theory, the general solutions of the wave functionscan be given, and an infinite linear algebraic equations ofthe unknown coefficients in the wave functions can be gottenwith the boundary conditions and the Fourier complex seriesexpansion technology, the infinite linear algebraic equationscan be approximately solved by the finite trunction withsatisfying some definite precision, at the basis of thissolution of the equation, the variations and the lay-outs ofthe DSCF at the circular cavity boundary vs. the differentincident angles, the different embedded depths of thecircular cavity as well as the different dimensionless wavenumber of the incident P-wave.

为此，本文采用一个半径很大的圆孔来代替半空间的直边界，将该半空间问题转化为一无限大空间中两个圆孔对稳态P波的共同散射问题，借助于成熟的柱函数理论，通过写出问题波函数的一般形式解，利用问题的边界条件，并采用复数傅立叶级数展开技术将其化为一个仅包含问题波函数中未知系数的一无穷线性代数方程组，在满足一定计算精度的前提下，通过有限项截断进行近似求解，进而讨论了圆孔边界处的动应力集中系数随不同入射角、不同的圆孔掩埋深度、入射波的不同无量纲波数以及介质的泊松比变化和分布情况。

Cardano did not use the mathematical signals in Ars Magna, and the mathematical tradition then was synthetic instead of analytic, therefore, most rules in Ars Magna were arithmetical but not algebraical.

由于卡尔达诺没有使用数学符号，并且当时的数学传统是综合而不是分析，所以《大术》中的绝大多数法则都是算术法则，而不是代数推理过程。

But the rate of mammitis will increase at the speed of 2％, at the same time, the number of daughters and sons of test bulls is not large enough for good accuracy for estimating test bull breeding value, so the breeding scheme in effect need to be improve.

C、现行的育种方案的育种成效不甚理想，世代间隔为5.42年，投入产出比为1∶11.50，但乳房炎发病率提高，公牛后裔测定的后代数低；现行方案还有较大的改进余地。

But in reality, they are just as ordinary as anyone else, in large scale; they are more pathetic than those blondes in high school who get lost in doing algebras.

但在现实中，他们只是作为普通的人一样，在大尺度；他们更可怜，比那些金发高中的人，迷失在做代数。

In this paper a further study of the algebraic properties of the language will be presented and the digital system will be optimized by program transformation. In this way, we can get a correct and optimized logic structure which has no redundancy and reuses each common component to the great extent.

本文将在此基础上，进一步研究函数或硬件描述语言的代数性质并通过程序变换对所描述的电路进行综合和优化，从而设计出正确的优化逻辑结构，在这种逻辑结构中去除了冗余，最大限度地重复使用各个子部件。

As same as the above-mentioned reason, because theconditions at the inside straight boundary of the binarycomposite material can not be easily satisfied, here, anelastic circular inclusion with large radius is used to replacethe upper half space of the binary composite material, so the〓mary binary composite mater ial problem can be changed〓the scattering problem of a circular elastic inclusion andto the scattering problem of a circular eastic inclusion and〓circular cavity in an infinite space to the steady incident〓wave.

与前面两个问题的理由一样，同样，由于问题中双质复合材料的内部直边界上的边界条件不易解析满足，为此，本文采用了一个半径很大的弹性实夹杂来代替问题中双质复合材料的上半空间部分，而将原来的双质复合材料问题转化成了无限大空间中一圆形弹性夹杂和一圆孔对稳态P波的共同散射问题，根据该问题的特点写出了弹性夹杂内外波场中波函数的一般形式解，利用该问题中夹杂和圆孔处的位移和应力的连续条件，并采用复数傅立叶级数展开技术将其化为一个仅包含问题波函数中未知系数的无穷线性代数方程组，在满足一定计算精度的前提下，通过有限项截断进行近似求解，进而讨论了双质复合材料中圆孔边界处的动应力集中系数随不同入射角、圆孔的不同位置、以及入射波的不同无量纲波数的变化和分布情况。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
