查询词典 evaporation

On the basis of whole grain evaporation age on single zircons using a double filament for different genetic zircons in metalassenite and metarhyolite of Luoyu formation,Yunkai group,the formation age of volcanic rock is 922 Ma;later geologic events is 643 Ma￣716 Ma or 427 Ma￣473 Ma...

本文采用颗粒锆石分层蒸发法分别对云开群罗罅组变英安岩及变流纹岩中不同成因锆石进行年龄测定，获得该火山岩之形成年龄为922Ma，940Ma；后期地质事件年龄为643Ma～716Ma，427Ma～473Ma及物源区的年龄为1616Ma，2084Ma。

Rainfall and water-surface evaporation were determined with Campbell meteorologic automatic observation system.

降水量与水面蒸发由Campbell气象自动观测系统测得。

Most of the precipitation intercepted in microbiotic crusts was dissipated through evaporation.

拦截在微生物结皮层的水分大部分以蒸发的形式损耗

In this paper, evaporation process of the typical microbiotic crust is studied by using micro-Lysimeter in vegetated area in Shapotou region.

笔者利用微型Lysimeter对沙坡头地区几种典型微生物结皮和流沙地表的蒸发过程进行了试验观测，并与水面蒸发进行了对比分析。

The increase of topsoil evaporation is due to that microbiotic crusts decreased soil surface reflectivity and enhanced the proportion of latent heat in net radiation.

地表蒸发量的增加是因为微生物结皮降低了地表反射率，并提高了蒸发潜热在净辐射中的比例。

As a result of its high capability in interception of precipitation and enhanced evaporation of soil surface, the development of microbiotic crusts will more and more threaten the soil water condition which the artificial sand-fixing vegetation should rely on.

微生物结皮的逐年发育使其对降水的拦截能力和地表的蒸发能力都逐渐提高，并改变了水分在土壤剖面中的分配过程和格局，这对人工固沙植被赖以生存的土壤水环境产生了越来越大的威胁。

Intercepted precipitation and enhanced evaporation by microbiotic crusts were the two main factors threatening the water reservoir in sand dunes.

微生物结皮拦截降雨和提高蒸发，是微生物结皮威胁沙丘土壤水库的两个重要因素。

Using the survey data of several indexes as well as field experimental data of soil hydrology of microbiotic crusts in artificial vegetation-fixed sand dunes in Shapotou area, the impacts of microbiotic crusts on soil hydrological processes which included the penetration, interception and evaporation processes of precipitation were examined, and their mechanisms were also studied. The security problem of vegetation-fixing system due to the changed soil water environment in fixed sand dune area was analyzed further.

本文在上面的立意下，我们对沙坡头人工植被固沙区对微生物结皮的若干指标进行了详细的调查和试验，并安排了一系列微生物结皮土壤水文过程试验，从不同的角度揭示了微生物结皮在降雨渗透、拦截和蒸发过程中的作用，及其对降水在沙丘土壤剖面中的水分分配过程和格局的影响，并进一步分析了微生物结皮对固沙区土壤水环境的影响和植被固沙体系的安全问题。

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。

At the height of 500hPa, evaporation of cloud droplets and the exchange between the cloud droplets and the monsoonal vapors may be the major reasons of a positive correlation betweenδ18O and wind velocity at the height of 500 hPa.

在500hPa高度，云滴的蒸发以及与下层向上层传输的季风水汽之间发生稳定同位素交换，可能是导致500hPa高度风的速率与δ18O正相关的主要原因，温度效应及降水量效应对这一关系的形成起促进作用。

Hanna: That's over now, isn't it?

都结束了，对吗

You must be ill. You look so pale.

你一定是病了，你的脸色苍白。
