conservation of mass

基本解釋

We invoke Dalton's Law of molar proportions, we write it subject to conservation of mass.
我們援引了摩爾分?jǐn)?shù)的道爾頓定律，要服從質(zhì)量守恒定律。
This paper defines what the law of conservation of mass means and its application in Junior chemistry.
論述了質(zhì)量守恒定律的內(nèi)涵，及其在中學(xué)化學(xué)解題中的應(yīng)用。
Conservation of mass, second Newton's law, and momentum law are introduced into traffic flow to set up traffic continuity equation, Euler's equation, and momentum integral equation.
應(yīng)用物理學(xué)中的質(zhì)量守恒定律、牛頓第二定律、動量定律等，建立了交通流的連續(xù)性方程、歐拉方程和動量方程；

So, what's the conservation of mass if we divide by the atomic masses here?
那麼質(zhì)量守恒是什麼呢？,如果我們在這兒按原子質(zhì)量劃分？
