surface soil

基本解釋

The average amount of water reported, if we were to extract it, is about a quart of water per ton (of surface soil).
如果要提取水，每噸（表層土壤）含水量大約爲一誇脫。
To put it another way, he said, about 16 ounces of water might be present for every 1,000 pounds of surface soil near the moon's poles.
換句話說，每 1,000 磅月球兩極附近的表層土壤裡，可能有 16 盎司的水，他表示。
The sample is from the surface soil that scientists say covers a layer of ice.

LCROSS will then study the soil thrown up to ten kilometers above the lunar surface before it too crashes into the moon.
The crash caused soil to be expelled many kilometers above the lunar surface.
Drop the seeds over the surface and cover them lightly with soil.

The remaining soil contamination is located several feet below uncontaminated surface soil.

表層土壤
In this paper, the surface soil (0-20cm) in the Xi’an 14 main parks has been carried on the synchronized open country investigation, sample gathering and the analysis test.
本文對西安市14個主要公園表層土壤(0-20cm)進行了同步的野外調(diào)查、樣品採集和分析測試。
耕層土壤
Farmland surface soil (0-30cm) nitrogen concentration directly affects the intensity and frequency of nitrogen loss. At the same time, it affects surface mud (0-5cm) nitrogen concentration of adjacent ditches of farmlands.
辳田耕層土壤(0-30cm)氮素含量直接影響辳田氮素流失的強度,也直接影響著辳田旁溝渠表層底泥(0-5cm)的氮素含量,在其它影響因素相同的前提下,辳田耕層土壤(0-30cm)全氮含量越高,辳田氮素流失的強度就越高,産生高水溶性縂氮濃度的次數(shù)就越多,辳田耕層土壤(0-30cm)速傚氮含量越高,辳田旁溝渠表層底泥(0-5cm)速傚氮含量就越高。
