method of orbital symmetry conservation 分子轨道对称守恒方法
On the other hand, were time symmetry to break down, conservation of energy would fail.
另一方面，如果时间对称性被破坏/不再成立，能量守恒就也随之不再成立。
The conservation of charge corresponds to time symmetry, while conservation of current corresponds to space symmetry.
电荷守恒对应于时间对称性，而电流守恒则对应于空间的对称性。
From the principle of symmetry, law of conservation of energy is proved. And have a simple geometric express for time translation symmetry and conservation of energy.
从对称性原理出发，证明了能量守恒定律，并对时间平移对称性与能量守恒作了简单的几何表述。
