Atmospheric precipitation

The removal of MMVF cement is likely to generate less atmospheric dust than the removal of the more friable insulating board and insulating compound.

拆除MMVF水泥产生的大气粉尘通常少于拆除更易碎的绝缘板和绝缘化合物时产生的粉尘。

By 1999, computer systems and software had finally become sophisticated enough to allow for the ability to underlay on the same workstation satellite imagery, radar imagery, and model-derived fields such as atmospheric thickness and frontogenesis in combination with surface observations to make for the best possible surface analysis.

到1999年计算机系统和软件终于可以胜任以下工作：为工作站提供支持、卫星图象、雷达成象和诸如大气厚度和锋生作用的建模。

As the application of the intermediate models is concerned, the works applying the intermediate models to investigate the topographic boundary layer, frontogenesis and low-level frontal structures, and the boundary layer jet are summarized in this article. It is mainly focused on the dynamic characteristics of the Ekman layer and its effect on the low-level structure and circulation of the weather systems illustrated by the models. It is shown that the intermediate boundary-layer models have great potential in illustrating the low level structures of the weather and climate systems as they are coupled with the free atmospheric models.

对于这些Ekman边界层近似理论模型的进一步应用问题，主要回顾和总结了利用上述模型探讨地形边界层结构、大气锋生过程、低层锋面结构和环流以及边界层日变化、低空急流形成等动力学问题的研究，并对这些研究所揭示的Ekman层动力学特征及其对自由大气低层运动的影响进行了分析，结果表明，这些Ekman边界层近似模型可以较好地揭示大气边界层动力学特征，在大气边界层动力学及其与自由大气相互作用的研究上具有重要价值。

It also shows that a negative correlation exists between the value of atmospheric water vapor and ground temperature in Gaize and Naqu, especially the negative correlation coefficient becomes larger in July.

研究结果还表明那曲和改则大气总水汽量平均日变化与温度平均日变化基本成负相关关系，这种关系在7月份尤为明显。

But the atmospheric galvanic effect reduces in Qingdao and increases in Wuhan with increasing exposure time.

随着暴晒时间的延长，青岛和武汉的大气电偶腐蚀效应分别呈降低和升高的趋势。

In this context, synthesis of diethyl oxalate from carbon monoxide in a gaseous phase at atmospheric pressure has precently received growing attention.

近年来，由一氧化碳常压气相催化偶联合成草酸酯的技术路线受到了人们的普遍重视。

Under atmospheric pressure, gasifier use waste biomass as fuel, and using air as gasification agent to carried out fluidized combustion, under the control of furnace temperatureto pyrolyse and gasify fuel, also, the fuel would split inside the boiler.

生物质气化炉以废弃生物质为燃料（食用菌菇菇肥、木屑、秸秆、果壳等），用空气作气化剂，在常压下进行流态化燃烧，在控制炉温下使生物质燃料热解气化，同时在炉内裂解。

The most polluted areas is near Tianjin second gasworks and around sewage river as well as sewage irrigation area. So we can conclude the major sources of pollution is atmospheric deposition and sewage irrigation. Second, It is positive correlation between the heavy-metal contamination and layered silicate minerals, while it is negative correlation between heavy-metals and quartz , feldspar as well as other minerals.

二、重金属污染元素含量与层状硅酸盐矿物含量呈正相关，而与石英长石等矿物含量呈负相关，充分说明污染元素主要赋存在层状硅酸盐矿物中，这与矿物自身的结构有着密切的关系，层状硅酸盐矿物具有很大的层间域，有利于对其他物质的吸附作用。

Based on the data of aerosol chemical compositions obtained at WMO GAW (World Meteorological Organization Global Atmospheric Watch) station in eastern China－Lin'An regional background air pollution monitoring station, two methods (referred as Malm method and Stelson method) that were described by Malm (Malm et al.,1994) and Stelson (Stelson and Seinfeld, 1981) were used to study the mass closure of sampled aerosols.

本文通过在WMO GAW 区域大气本底污染监测站－临安大气本底污染监测站采集的气溶胶样品的化学成分的分析结果，分别用Malm（1994）和Stelson（1981）提出的方法（分别记为Malm方法和Stelson方法）重建气溶胶质量浓度，并与称重获得的质量浓度进行对比，发现虽然Stelson和Malm方法所考虑的物质组成及所使用的化学成分个数并不相同，其计算结果略有差异，但总的来说两种方法都能较好的反映绝大部分的气溶胶质量，在实际应用中可以根据所分析的化学成分数据情况和研究的目的采用不同的质量重建方法。

However it can often be frust ating for a child when people are unable to pronounce their name.

但它往往可以令人沮丧的一个孩子当人们无法断言他们的名字。

All these compounds were obtained from this genus for the first time. Compound, 4-cumylphenol, was a new nature product.

所有化合物均为首次从本属海藻中分离得到，其中4cumylphenol为新天然产物。
