physical law

基本解釋

The physical law that the volume of a fixed mass of gas held at a constant pressure varies directly with the absolute temperature.
物理定律，在不變壓力下，一定質(zhì)量的氣體的體積與絕對(duì)溫度的變化成正比。
Next take the typical three-inertia Electrical position servo system as the research object, according to the system physical law set up a dynamic model of servo system.
其次以典型三慣量機(jī)電位置伺服系統(tǒng)為研究對(duì)象，根據(jù)系統(tǒng)的物理定律建立了伺服系統(tǒng)的動(dòng)力學(xué)模型。
But if someone were to find a counter-example to a physical "law", it would go back to being a hypothesis, and we'd have to repeat more experiments to see if we need to tweak our "law".
如果有人找到一次的例外，這定律就要被放回假設(shè)。就要再做實(shí)驗(yàn)，看是否應(yīng)修改目前的“定律”。

物理定律
Movement of any substance subject to certain natural routine . Usual partial differential equations are mathematical model describing movement of relation between some physical value which is determined by corresponding physical law.
任何物質(zhì)的運(yùn)動(dòng)都受到一定的自然規(guī)律的制約，我們常見的偏微分方程就是作為描寫這些物質(zhì)運(yùn)動(dòng)的數(shù)學(xué)模型，它們從數(shù)量形式上刻劃了由相應(yīng)的物理定律所確定的某些物理量之間的聯(lián)系。
