The soil which was moderate pH has the advantage of cumulating calorific value. 中性和近中性土壤有利于苜蓿熱值積累和光能累積。
The calorific value of Medicago populations from northern Xingjiang and cultivars were measured using Parr measurement. 摘要用氧彈式自動(dòng)測熱儀測定苜蓿不同種群植物體的熱值。
This coal has a high calorific value. 這種煤有很高的發(fā)熱量。
Inhomogeneous thermal power density and temperature distribution of inside-pumped solid-state tube lasers have been derived in this paper. 本文導出了內泵浦方式下管狀固體激光器的非均勻發(fā)熱量和溫度分布。
