Task revenue function is related to fire density, burning time and number of fire put out by robots, which is consistent with the realistic fire-fighting task model. 收益函数与火势、燃烧时间和机器人扑灭火灾数有关，这切合实际救火模型。 - 2
The tax system in our country should be reformed as he followings: according to the requirement of sufficiently developing tax revenue function, establishing the tax system reasonably; 我国的税制应做如下方面的变革：按照充分发挥税收职能作用的要求，合理地设置税制体系； - 3
In this paper I get the profit be maximum, as the revenue function, cost function are continuous differential and the margin revenue equals margin cost, that marginal profit equals zero. 当收入函数、成本函数为连续可微函数，边际收入等于边际成本，即边际利润等于零时，利润最大；但在离散情况下，上述结论不一定成立，并给出反例。
