当入射光束与出射光束平行时，单色同心光学系统空间任一点成几何理想像。

If a monocentric system existed for which an incident collimated beam emerged as exactly collimated, then the system would give geometrically perfect imaging of any point in space.

该计算方法包含了三个计算过程：第一，规定了每个像素理想像高的坐标表示法；

This way includes three processes: the first process provides a coordinate for ideal image height per pixel in the picture;

系统采用基于点阵样板的校正方法，拟合理想像与实际像的关系，完成像素点的几何位置校正和灰度校正；

The hardware system is based on the dot-array plate arithmetic, fitting the correlation between ideal image and real image, and achieving the correction for location and gray-level of image pixels.

Let's try it with a different equation of state, that isn't quite as simple as the ideal gas case.

考虑一个不同的状态方程，这状态方程不像理想气体状态方程那么简单。

This needs to be stressed that this is the ideal gas case. Now regular gases, real gases fortunately as I said, don't obey this.

需要强调的是这是对理想气体而言的,普通气体，真实气体，就像我说过的,不遵循这个规律，这是非常重要的。

Ideally like we started today, it will be a bit more like a conversation to the extent that's possible in a theater like this.

理想情况下就是，像我们今天这样，这可能会更像一种,在剧院里面的对话一样。
