On the basis of the changed value of oxidized elements and atoms in the oxido-reducing reaction, relative coefficient is adopted to make it easy to equalize square equation.

配平氧化还原反应方程式的原则是：还原剂氧化数升高的数值等于氧化剂氧化数降低的数值。

Write in the third person (" the aquifer covers 1000 square kilometers ") or the first person plural (" We see from this equation that acceleration is proportional to force ").

用第三人称写(“含水层涵盖1000平方公里”)，或第一人称复数(“从这个等式我们看到，加速度与力成正比”)。

Einstein's famous equation, E=mc2, outlines how energy is equivalent to mass times the square of the speed of light.

这个道理可以参考著名的爱因斯坦质能方程式，E=mc2, 能量E是质量m乘以光速c的平方项。

If you want to write it as a vector equation, you want to write it as v square over r minus-- I want to say that it's pointing in the direction toward the center.

如果要写出矢量方程,就应该写成 -v^2 / r,也就是说,方向就向圆心
