On global optimal algorithms, a heuristic 0-1 Integer Liner Programming algorithm is achieved, which combines heuristic enumeration method and revised simplex method. Simulation experiments show that the degree and optimization efficiency in our algorithm is obviously improved compared with the MATLAB 7 bintprog function that is a 0-1 integer programming algorithm. Moreover our algorithm isn\'t relevant to the scale changes of Web services composition and candidate service sets, thus it is applicable for the scenes that the scales of Web services composition changed dynamically. But for Web services composition with service alliance, the algorithm is unable because the non-linear global optimal model of the fitness function and QoS constraints can\'t be expressed in linear mode.

在全局优化算法研究上，基于启发式0-1整线性规划算法结合了修正单纯形法和启发式枚举法，仿真实验表明该算法与MATLAB 7的0-1整数规划方法比较，在优化程度及优化效率上得到了显著改进，并且对服务组合和候选服务集合的规模变化没有明显的相关性，因而该算法可用于服务组合规模动态变化的场景，但该算法不能应用于存在服务联盟的非线性全局优化模型。

In order to meet the demand of precise measurement and applications, the principle of phase retardation with oblique incident angle is expounded, based on the total-reflection phase transformation theory of the phase retardation. By means of Fresnel rhomb, the variation law of the phase retardation for rhomb-type retarder with the incident angle is analyzed. The result indicates that incident angle has obvious influence over the phase retardation.The phase retardation is sensitive to the incident angle, and also has close correlation to incident position of the incident ray, which is asymmetrical to the incident position of the incident ray.

为满足精确应用和测量的需求，从相位延迟的全反射相变理论出发，阐述了斜入射相位延迟原理，以菲涅耳菱体为例，分析了菱体型相位延迟器相位延迟随其入射角变化的规律性，结果表明：当光线非严格准直时，光的入射角对相位延迟量有明显的影响，延迟量不但对入射角变化敏感，而且还与入射光线的入射方位密切相关，呈不对称形式。

Under the same situation as tube-diameter and so on, yield load and limited load increase with the increasing of steel tube ratio. But the steel tube ratios variety has ruleless to maximum displacement of the upper column.

2在钢管外径等其他属性相同的情况下，屈服荷载与极限荷载随含钢率的增大而增大，但含钢率的变化给柱顶最大位移带来的变化不具有规律性。

To love is like to sail, there will be no perfect weather,no safest route, but if you are a good sailer, you can always fight the uncertainties with your ecperiences,and the most significant, your intuition.

就像航海，一个航海家不会喜欢没有变化的航程、完美的天气预报，他喜欢的是在海上感觉流向的变化，按照心意去协调，才能达到目的地。

Additionally, the type of methyaltion changes in plants after seed and seedling irradiation were different.

另外，甲基化和去甲基化变化类型的分析也表明种子和幼苗辐射后发生甲基化变化的趋势也不相同。

Starting from the real individual, Marx enters into the dimension of practice, and then he answers correctly to these two questions. For the real individual, the nature is not the abstract and isolated self-dependent nature, but the practical and humanized nature, namely the man and the nature are united. The production in which the real individual engaged is the material foundation on which the social consciousness relies, and with the change of social existence, the social consciousness changes as well; in other words, the social consciousness and the social existence are united.

马克思从"现实的个人"出发，进入生活世界的实践维度，对之作出了正确的回答：对于现实的个人而言，自然界不是抽象的、与人割裂的自在自然，而是现实的、与人结合的人化自然，也就是说，人与自然界是统一的；现实的个人所从事的生产劳动，是社会意识得以产生和存在的物质基础，社会意识随着社会存在的变化而变化，也就是说，社会意识与社会存在是统一的。

但是半导体激光器作为一种高功率密度并且具有极高量子效率的器件，微小的输入电流和温度的变化都将导致输出光功率的极大变化，即使在小功率下也不能在室温下连续工作。

This paper studies the change pattern of soil strength in the different water content as an example of silty clay soil in Beijing area. The results have shown that the changes of water content in the scope of 10-20% have greatly influences on soil strength.

结果表明：随着含水量的增大，土的强度降低，但降低的幅度不一样，当土的含水量在10～20％之间变化时，含水量的变化对土的强度影响极为明显。
