Critical angle of refraction - semi-circular cylindrical mobile light source, the incident angle change the size of refraction angle to change at this time, when the refraction angle = 90 degrees, which is critical at this time angle of incidence angle, the critical angle of water at 40 degrees large about anything mobile source of water in the water screen that is a reflection of light, a phenomenon that total reflection.

光折射的临界角定义：光折射角=90度时，入射角即为临界角，按二方法，将半导体激光光源去掉铁夹，吸附在右下角的铁板上入射光对准中心，即产生折射光线，沿半圆形柱面移动光源，改变入射角的大小，这时折射角也改变，当折射角=90度时，这时入射角即为临界角，水的临界角大的在40度左右，再做移动光源在水中的水屏即出现反射光线，这种现象称全反射。

T2 Q2 P2 (V4 V3 ) P2 (V4 V3 ) P2 (2 points 2 分) Therefore, one may define the absolute temperature by T = AP1/4 , where A is an arbitrary constant.

因此我们可以定义温度为 T = AP1/4 ，中 A 为任意常数。

On the base of Frege's study, Russell put forward the theory of types to settle Russell's paradox. On the base of non-set, Russell brought forward axiom of infinity and axiom of option as the premises and built a system. He tried to defined the non-negative integer in logic terms and derive the theorems of arithmetic from the laws of logic by deductive method.

罗素在弗雷格研究的基础上，提出逻辑类型论来解决罗素悖论，以非集合论理论为基础，以无穷公理和选择公理为前提，利用逻辑概念定义数学概念，并构造系统，通过逻辑演绎法从逻辑公理推导数学定理。

Then for the drive shaft back to the prop I had to customize the dogbone fittings to fit onto a 3/16 shaft that they were not designed for.

然后为传动轴返回到版权，我不得不自定义dogbone设备，以适应上3 / 16轴，他们没有被设计为。

First, the formal representation of the search environment is established, the multi-UAV is modeled as a controlled system and the predictive model of the system is presented. Considering the uncertainty of the sensor measurement and the environment, a Search Probability Map is defined and the updating method based on Bayes formula is presented. Based on SPM, information gain is defined to measure the search effects and used to be the optimization object in the predictive horizon. By using of GA, the solution of the optimization problem is got and it is taken as the input of the controlled system.

首先，建立搜索环境的规则描述，然后将多个UAV建模为一个控制系统，建立系统的预测模型，考虑到UAV传感器测量的不确定性和环境自身的不确定性，建立搜索概率图描述搜索环境的不确定性，给出了基于Bayes准则的搜索概率图更新方法，继而基于搜索概率图定义信息增益来衡量搜索效果，并将预测周期内的优化目标定为最大化信息增益，采用遗传算法进行求解，得到最优解作为被控系统的输入。

It is proved that when all the ratios of the generic term of a subaddtive sequence to its ordinal number form a lower bounded sequence,the ratio sequence must have limitation .

从这一结果出发证明了，当定义在(0，+∞)上的次可加函数与其自变量之比为有界函数时，次可加函数必存在上下确界函数，并证明了其上下确界函数均为齐次线性函数。

Luminous intensity is indicated with the symbol I and its unit of measurement is the candela.

其定义符号为 I 以及其测量单位表示为烛光。

The second part is the computational methods of the determinant: This part is core part in the full text, and mainly studied 14 kinds computational methods which nearly covered each kind of the characteristic of the determinant computation, including the definition method, the triangle method, Canada method and so on.

第二部分为行列式的计算方法：这一部分是全文的核心部分，主要研究了几乎覆盖各种特征的行列式计算的十四种重要方法，包括定义法、三角形法、加边法等，它们为我们计算行列式提供了方便快捷的途径。

At the same time , we discuss the determinism and nondeterminism of formula-clock automata and the closure propertied under Boolean operation of the language which is accepted by formula-clock automata. We also prove the expressive equivalence between the deterministic formula-clock automata and the nondeterministic formula-clock automata. This means that every nondeterministic formula-clock automata can be transformed to a deterministic formula-clock automata which exactly accept the timed language identified by the fomer.We also extend timed words to infiniteness and define the formula-clock Buchi automata and the formula-clock Muller automata. At last, we show its application in formal verification and modeling of real-time system.

然后讨论了公式时钟自动机的确定性和非确定性，公式时钟自动机识别的语言类在并、交、补运算下的封闭性；并证明了确定的公式时钟自动机和非确定的公式时钟自动机表达能力的等价性，这意味这每一个非确定的公式时钟自动机都能转换为一个与之识别相同时间语言的确定的公式时钟自动机；我们将时间字扩展为无穷的，从而定义了公式时钟Buchi自动机与公式时钟Muller自动机；最后给出了用它进行实时系统的形式化验证方面及对实时系统建模的应用。

For example, if you have quarters represented as "First Quarter 2004","Second Quarter 2004", etc., you can define a member property with abbreviated names like "Q1 04","Q2 04" etc. and set a flag to show the properties when the field is placed in the column area, making the report more readable.

例如，如果你有一些季度，表现为"First Quarter 2004"，"Second Quarter 2004"，等等，那么你可以定义成员属性为一些缩写的名称如"Q1 04"，"Q2 04"等，并且当放置该字段到列区域时设置一个标志以显示该属性，这样可以使报表更易读。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
