可变量

This function can be used to get the address of a variable or an array element. It takes the variable name or the array element as the parameter and returns the address.

这个函数可用于获取变量或数组元素的地址，它以变量名或数组元素为参数，返回相应地址。

Due to historical reasons, note that the alternate variable assignment syntax listed above does not exactly match the syntax for variable assignment within an expression.

由于历史原因，注意上面列出的变量赋值的可代替语法不全同于用表达式赋值变量的语法。

Due to historical reasons, note that the alternate VarAdd syntax listed above matches neither the syntax for variable assignment within an expression, nor the syntax for variable addition within an expression.

由于历史原因，注意上面列出的VarAdd可代替语法既不能将变量赋值用于表达式内，也不能将变量加用于表达式内。

The coefficient of determination, r^2 measures the proportion of the total variation in the value of one variable that can be explained by variations in the value of the other variable.

可决系数 r^2，表示一个变量的变化可以用 r^2%的另一变量变化来解释。

The control variable is just a normal variable and is accessible to the program just like any other.

控制变量是一个常规的变量其值是可控的就像任何其他程序。

The maximum principle of the optimal control for the stochastic systems described by Zakaj stochastic partial sifferential equationis proved by approximately minimum point theorem of E. Ekeland. The convexity and compactness of the set of control values is not assumed, and it is not necessary for the maximum principle about differentiability in control variables included in drift term of the stoch astic system and the integrand in index functional, and costate process satisfies the stochastic partial ...

在不假便定控制变量取值的集合是凸的和紧的，不要求随机系统的漂移项和指标泛函的被积函数关于控制变量具有可微性的情况下，用E，Ekeland的近似极小点定理证明了Zakai随机偏微分方程描述的随机系统的最优控制的最大值原理，和用很简洁的方法证明了协态过程满足一个随机偏微分方程。

Comparing with Daikon,the method has two excellent features.Firstly,it is better expansible based on the RDBMS technology;Secondly,discovering of program invariants can be accomplished by the function of SQL query based on the technology of relational database which can detect the program invariants in a nimble way.

该方法和Daikon等现有的程序不变量检测工具检测方法比较具有明显的特色和优势：第一，基于关系数据库技术，具有良好的可扩展性；第二，使用SQL条件查询功能实现非函数依赖程序不变量检测，检测方法具有很好的灵活性。

Chapter two proposes the unified form of Hojman"s conservation law and Lutzky"s conservation law. Firstly, the author introduces the general Lie group of transformations that the variations of both the time and the generalized coordinates are considered, derives the determining equation of Lie symmetry for the system, presents a new conservation law, which contains the Hojman"s and the Lutzky"s conservation law as two special cases, and obtains a condition to exclude trivial Hojmans conserved quantities.

第二章，Hojman定理和Lutzky定理的统一形式：首先，引入一般意义下的Lie变换群(即位型变量q_s和时间变量t同时变换)，给出系统的Lie对称性确定方程，提出一个新的守恒律，Hojman定理与Lutzky定理则分别是这个新守恒律在两个特殊情况下的推论，导出一个可排除平凡Hojman守恒量的定理，并分别讨论了Birkhoff系统和非完整系统的Lie对称性和Hojman守恒量，最后，讨论了Hamilton系统的梅对称性与Lie对称性的关系，给出了由梅对称性求Hojman守恒量的方法。

If the value of two-dimension random variable is finite or countable, then is called two-dimension discrete random variable.

Definition 3.3 如果二维随机变量可能取的值只有有限个或可列个，则称为二维离散型随机变量。

In order to find out some more elementary recessive variables, which hide among a set of fathomable variables and cannot be measured directly.

找出用来描述隐藏在一组可测量到的变量中的一些更基本的但又无法直接测量到的隐性变量。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
