1·Three simplified methods for estimating the volatilization of ammonia from flooded rice fields were assessed when the plants are small and sparse in the field at Lianhu Farm, China.
在中国丹阳练湖农场进行的田间试验中，研究和比较了稀疏幼小稻苗生长下测定水稻田氨挥发的三种简化方法。
2·Ammonia volatilization appears regular change in the condition of the same amount of urea applied to the soil with different treatments of phosphorus fertilizer application.
当等量尿素追施入不同施磷处理土壤后，氨挥发速率出现规律变化。
3·Using the infrared heating theory, it can accelerate the volatilization of the attenuant of the paint and shorten the time for drying.
使用红外线加温原理，加快涂料稀释剂的挥发和油漆的化学反应，缩短涂料等候干燥时间。
4·They can not only remain tank internal normal pressure, but also prevent over pressure or vacuum in tank reduce liquid volatilization loss in tank.
它不仅能维持储罐气压平衡，确保储罐在超压或真空时免遭破坏，且能减少罐内介质的挥发和损耗。
5·The experiments on volatilization of diesel oil on watch-glass and in soil were carried out.
对柴油进行了在玻璃表面皿上和在土壤中的挥发实验研究。
