很难想象没有微积分，牛顿能够发现经典力学。微积分的发现要追溯到阿基米德。
It is difficult to imagine that Newton can develop classical mechanics without the great language of calculus whose development can be traced back to Archimedes.
试验研究表明，该模型处于热量自模拟区，热量阿基米德数的改变对其工作区温度分布没有显著影响。
It is implied that this model is located in the model area of self, and the change of number have no direct effect on the temperature's distribution in the working units.
