The operation of natural law is constant. 自然法則的作用是永恒的。
How admirable is this Law of Compensation! 這種補償法則真是太妙了！
The ratio of the intensity of black body radiation at four wavelengths was calculated by the blackbody radiation law. 摘要本文從黑體輻射定律出發(fā)，計算了物體輻射譜在四個(gè)不同波長(cháng)處輻射強度的比率。
Although silicon is an indirect semiconductor, light emission from silicon is governed by the same generalized Planck's radiation law as the emission from direct semiconductors. 雖然硅是一種非直接躍遷半導體，但它的發(fā)光機制同樣服從于直接躍遷半導體的廣義普朗克輻射定律。
