北京作为首都，也是特大型城市，郊区有方圆近 16000玩，的面积，承担着首都食品生产基地、生态环境绿地、城市环境发展疏导地的作用，同时发挥着自身农村经济生长地等多重功能。京郊农业自改革开放以来，依靠北京在

Based on genetic algorithm,a new hybrid coding method using the integer and floating number was presented. The enumerable method guarantees each individual in the population to satisfy the constrains, thus the punishment function was avoided. The two adjustable parameters made the evolution process jump out of the local best solution perfectly.The application of the fitness assignment based on Pareto ranking attained inferior solution set of the multi-objective and multiple options were provided to the decision-maker.

设计了一种新的整数和浮点数结合的编码方式；通过列举法使得每代个体满足约束条件，避免了罚函数的使用；可调整的双参数变异算子使进化过程能够较好地跳出局部最优解；应用基于Pareto排序的适应值分配方式得到目标函数的非劣解集，为决策者提供了多种选择方式。

当指标函数没有明确的解析表达式，或者对变量有整数要求时，用表格法。

Because the characteristic equation of fractional order system is a pseudo-polynomial function with exponential-type fractional orders of complex variable, the control of integer orders cannot be directly applied to it.

分数阶系统的特征方程是一个具有复变量的分数阶指数的伪多项式，因此不能直接应用整数阶系统的控制方法。

The net result of this function is no change to the integer at the end of the pcounter pointer: whenever control leaves the guarded body for any reason, including a return statement or a goto , the termination handler executes.

这个函数的纯结果是：在 pcounter指示器的最后不改变这个整数：无论控制在何时以什么原因离开防护体，包括一个返回声明活着一个goto语句，最终处理器执行。

In order to improve the computational efficiency, a branch algorithm for general integer linear programming problems on the objective function hyperplane shifts was presented.

为了提高求解一般整数线性规划问题的效率，提出了一种基于目标函数超平面移动的分支算法。

The 'is' operator compares the identity of two objects; the id function returns an integer representing its identity (currently implemented as its address).

一旦对象建立了，它的标识就不能改变了；你可以认为它是内存中的地址。

The ' is ' operator compares the identity of two objects; the id function returns an integer representing its identity (currently implemented as its address).

is ' 操作符可以比较两个对象的标识； id 函数会返回对象标识的一个整数表示。
