Meanwhile, analyze the experimental result, do attack experiment use natural soil, air-dry soil, stoving soil and preparation seil, observe the difference.
同时，对试验结果进行了分析，土样采用天然土、风干土、烘干土、制备土进行击实试验，以观察试验结果的区别。
By using a numerical model for seil and ground surface temperatures the effects of some factors on computations are discussed in this paper.
本文用一个土壤和地表温度的计算模式，讨论了土壤物理参数、大气中的云量、大气透明度、土壤模式层厚度以及温度初值给定方法等因子对土壤和地表温度计算结果的影响。
The spatial variation law of seil erosion intensities within a small water-shed and the relationships between erosion intensities and landform or land use were researched.
进而研究了流域内侵蚀强度的空间变化规律及其与地貌和土地利用的关系。
