物理的守恆定律？

仲有好多，如
conservation of baryon number
conservation of lepton number
conservation of strangeness ((not conserved for weak interaction)
conservation of isospin (not conserved for electromagnetic/weak interaction)
conservation of parity ((not conserved for weak interaction)
conservation of hypercharge ((not conserved for weak interaction)
其他在全部interaction (strong,weak,electromagnetic)都conserve的。

Also conservation of parity.
