火力

To arrive at practical and effective solution to the current management of the relative shortage of coal thermal power plant.

得出能够切实有效的解决当前火力发电厂煤炭管理相对不足的方案。

The primary work of this paper includes: 1 The general process and the fundamental theory of genetic algorithm is introduced systematically, which is also be applied to an example; 2 The penalty function method and the constraint tournament method are introduced in the paper, which are used to process the constraint limit. Via analyzing the basic principle of NSGA-II ,which is elaborated in the paper, the fast non- dominated sorting method, congestion distance and its comparison operator, the elite strategy and the main process of NSGA-II is researched particularly. 3 Via modeling the fire distribution problem, the model is computed by the algorithm of NSGA-II, which is combined with both the penalty function method and the restraint league tournament method The optimization of two goals are also realized in the paper. The results derived from the VC++6.0 indicate that, two algorithms both have the high convergence, simultaneously the Pareto optimal solution also maintain the variety of distribution.

本文所作的主要工作如下：系统地介绍了遗传算法的一般流程和基本理论，并应用于一个函数优化的实例；研究了用于处理约束限制的罚函数法和约束联赛法，论述了NSGA-II的基本原理，并对其提出的快速非支配排序法、拥挤度及其比较算子、精英策略及NSGA-II的主要流程作了详细的研究；建立了火力分配问题的模型，并将NSGA-II算法分别与罚函数法和约束联赛法相结合对该模型进行了计算，实现了对两个目标的最优化；用VC++6.0编程计算后所得的结果表明，两种算法均具有很好的收敛性，同时Pareto最优解也保持了好的多样性分布。

I remember sloshing back to where he went go down with the company corpsman and uh, we started returning fire and providing a covering base of fire, calling artillery in and scheduled an emergency medivac helicopter to come in and get Lt.

我记得我泅渡返回到他和连队走过的路，我们开始还击并且提供了一套火力装备，我们请求炮火支援，并且安排了紧急救生直升机把Lt。

It depended on the situation. There could be such counteraction -- Lord help us!

答：这要看情况，如果有很强的防御火力--上帝保佑！

I've got the entire battalion on covering fire.

我会要整个营作为你的掩护火力

Provided covering fire for the platoon that was moving up.

为行进中的部队提供火力掩护。

It's just covering fire! Save your ammo!

Whether it's hauling a stuck car out of a ditch or providing covering fire for a flanking action,as long as he's providing assistance to others.

无论是把队友从沟里拖出来，还是为侧翼行动而提供火力掩护，只要是能够给别人提供帮助的，他都十分乐意。

Covering fire. Two civilians, twelve o'clock.

2-2 火力掩护有两个人十二点方向

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
