查询词典 crusts

So studying the processes and mechanisms of soil hydrology of microbiotic crusts as well as analyzing its influence on soil water conditions in fixed dunes will play an important role theoretically and practically in understanding the evolution of artificial vegetation community in fixed dunes and the security of artificial sand-fixing vegetation system.

因此，通过野外试验揭示微生物结皮对土壤水文过程的影响和机理，评估其对雨养植被固沙区土壤水环境的影响，对于认识固沙区人工植被群落的演替和人工植被固沙体系的安全性都有着重要的理论意义和实践意义。

Microbiotic crusts had a high capacity of evaporation than the shifting sand dunes. During the evaporation process of one week after rainfall, the total evaporation in artificial vegetation regions constructed in 1956, 1964, and 1981 were 6.05, 4.99 and 4.23 times respectively as the total evaporation in shifting sand dunes.

微生物结皮有着比流沙区更高的蒸发能力，在雨后一周的蒸发过程中，1956、1964和1981年人工植被区的总蒸发量分别是流沙区总蒸发量的6.05、4.99和4.23倍。

The thin layer of microbiotic crusts with lower bulk density, lower density, higher soil porosity and higher water-holding capacity will markedly influence the soil hydrological processes, such as the processes of penetration, the interception, the redistribution and the evaporation of precipitation, which will threat the soil-water environment in Shapotou area.

容重较小、比重低、孔隙度高和持水性能强的薄层微生物结皮对土壤水文过程产生了深刻的影响。在沙坡头地区，微生物结皮改变了降雨在沙丘土壤中的渗透、再分配、拦截和蒸发等过程，并最终导致固定沙丘土壤水环境的恶化。

In this study, with the psammophilous Caragana Korshinskii-Artemisia ordosica communities on semifixed dunes and fixed dunes in Shapotou region at the southeastern fringe of the Tengger Desert as the observation sample plots, the survey quadrats were arranged in the vegetation community areas with different types and coverages of soil microbiotic crusts.

本文以腾格里沙漠东南缘的沙坡头地区半固定沙丘柠条一油蒿群落和固定沙丘柠条一油蒿群落为观测样地，选择具有不同类型生物土壤结皮分布的植被群落为观测样方。

Skim milk, crusts, middlings, bits of doughnuts, wheat cakes with drops of maple syrup sticking to them, potato skins, left-over custard pudding with raisins, and bits of Shredded Wheat.

脱脂牛那、面包皮、麦麸、炸面圈碎块、上面滴着槭糖浆的麦饼、土豆皮、吃剩的葡萄干蛋奶布丁、脆麦片条屑屑。

Skim milk, crusts, middlings, bits of doughnuts, wheat cakes with drops of maple syrup sticking to them, potato skins, leftover custard pudding with raisins, and bits of Shredded Wheat.

6：30吃早餐。脱脂乳、面包皮、粗麦、几块油炸圈饼、上面粘着枫蜜的小麦饼、土豆皮、吃剩的葡萄干奶油布丁和一些小麦片。

When the above process circulates to some extent, saprolitic crusts will be formed inside structural planes.

腐岩壳在雨季直接吸收、贮存流经其表面的液态渗入水，在核心石外侧形成富水结构层并在旱季向包气带或其内侧的风化前锋提供水汽。

Weathering crusts of which the sections are made up of 3 or 4 layers are the clay type composed of illite, smectite and ancudite.

风化壳上部是发育好的红色古土壤，中部是含铁质胶膜的风化破碎黄土，下部是不含铁质胶膜的风化破碎黄土。

I have to get the sandwiches, which have all of their crusts.

我得去拿有面包外皮的三明治

There is no evidence that such crusts have any direct adverse effect on apple trees.

没有材料证明，这种硬皮对苹果植株有任何直接的不利影响。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
