无限小地

Through an infinitesimal contact transformation, the system was deduced to a torque-free rigid body with moments of inertia varying periodically with time. It can be taken as a Euler-Poinsot motion perturbated by small periodic excitation.

通过无限小接触变换，将系统等价为无力矩作用下自由刚体运动，但其转动惯量仍随时间周期地变化，从而化作周期摄动的Euler-Poinsot运动。

But when dealing with large masses or time periods that are infinitesimally small, like the core of a black hole or the first moments after the Big Bang, neither quite works.

2但是在研究大质量物质或无限小的时间段时，比如，对黑洞的核或者是宇宙大爆炸后的最初时刻，二者都不能完美地加以解释。

Only limiting this element of free will to infinity, that is, regarding it as an infinitesimal minimum, we are convinced of the complete unattainability of causes, and then, instead of seeking causes, history sees before itself the task of seeking laws.

只有无限地约制这种自由意志力，就是说，把它看作无限小的数量，我们才会相信原因是完全不可理解的，于是历史把寻求法则作为它的任务，以取代对原因的探寻。

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。
