Historiographer culture, which produced in the state of developed substance civilization and the understanding level to be improved, had a distinct reason.

Under the domination by reasonism spirit, the historiographer always described the origin and development, cause and effect of the historical events in great detial, in order to give warnings to the contemporary era.

士人文化与士人散文产生于王纲解纽的自由时代，其思维模式往往是以时空结构为思维的参照系，注重事物之间的相似联系，可称之为时空—相似思维。

In fact, the construction of the geometry structure would be ill-use of a series of qualified formula in tensor analysis and where there is perplexity about coordinate system, reference system and geometry space.

事实上，相关几何结构的构建不仅混淆了坐标系、参照系、几何空间等彼此不同的基本概念，而且，只是对张量分析中若干"条件成立"公式的滥用。

This is the nature of the universe of Einstein's first assumption: all inertial reference frame in the physical laws are the same.

这是爱因斯坦对宇宙本性的第一个假设：所有惯性参照系中的物理规律是相同的。

Of Einstein's special theory of relativity, a good solution to the speed of light for all inertial reference frame of the observer are constant speed c.

The significance of this issue is not yet a large majority of the people, after all, we absolutely are in the inertial frame of reference, if requested Yang Liwei a feeling this might be helpful.

这个问题的意义目前还不是很大，毕竟我们绝对大多数人都处在惯性参照系中，如果能请杨利伟对此发表感受或许有所帮助。

An aircraft in steady flight over the earth is just as suitable an inertial frame of reference as the earth itself.

在地球上空稳定飞行的飞机，正如地球本身那样，也可作为惯性参照系。

Observed from an inertial reference frame, the net force on a particle is proportional to the time rate of change of its linear momentum: F = d / dt.
