查询词典 vapor

The results indicated that,during MV drying,moisture distribution in wood was relatively uniform,without an obvious moisture content gradient along the direction of thickness of wood.Moisture distribution in wood was more uniform in the last period of drying.Above Fiber Saturation Point,the movement of moisture through wood was assumed to be permeable movement of free water and vapor under the action of pressure gradient;below FSP,moisture existing in vapor form in wood moved in response to a pressure gradient.Moisture transfer caused by heat diffusion and a moisture content gradient could be neglected.

研究结果表明：在微波真空干燥过程中，木材内部的含水率分布比较均匀，在厚度方向没有明显的整体性含水率梯度，特别是在干燥的后期，木材内部的含水率分布更加均匀；当含水率在纤维饱和点以上时，木材中的自由水和水蒸气在压力梯度的作用下以渗透流的形式在木材内部迁移；当含水率在FSP以下时，木材中的水分在压力梯度的作用下以水蒸气的形式向木材表面迁移；因热扩散、含水率梯度引起的水分迁移可以忽略不计。

Environment factor effected the water vapor flux variation. Net radiation and ground heat were key factors to affect water vapor flux.

环境因子在很大程度上制约着水汽通量的变化，以净辐射和土壤热通量地温对水汽通量的影响最大。

碘激光有6条超精细谱线，单一最强线频率的碘激光的大气分子吸收比多谱线的碘激光小，更有利于大气传输。

To obtain sulphuric acid, Cyrus Harding had only one operation to make,to calcine the sulphate of iron crystals in a closed vase, so that thesulphuric acid should distil in vapor, which vapor, by condensation, wouldproduce the acid.

赛勒斯·史密斯制造硫酸的最后一道工序，是把硫酸铁的结晶密封在瓶子里，进行锻烧，使之蒸发为水汽，经过冷却，就可以变成硫酸了。

By way of introducing expression of salt solution concentration and Hendeson equation that describes equivalent moisture curve of hygroscopic material, the heat and mass transfer model is simplified and provides a theory proof that the transportation direction of water and vapor in the pore material is opposite but effects of two items can be integrated as an expression, Compared to traditional vapor permeating, the calculated results from the presented model in this paper that salt is not taken into considered is accurate.

根据建筑围护结构自身所处环境特点，开拓性建立了吸湿区范围内含盐多孔材料的热质迁移数学模型，通过引入描述平衡湿度曲线的Hendeson方程和盐溶液浓度的表达式，对含盐多孔介质热质迁移数学模型进行了简化，从理论上论证了多孔材料中液态水分和水蒸汽迁移二者过程的相反性和统一性。

The purpose of the study is to investigate the performance of the complex vapor chambers composed of various particle diameters (270~400mesh) and structures (particle or tree-like shapes). In this study, the wickers consisted of sintered copper powders and meshes were used to form the complex vapor chambers in the evaporation area.

Vapor explosion is a compositive multiphase phenomenon including four stages: coarse premixing, triggering, propagation and expansion. The mechanisms involved in the vapor explosion process have not been understood, which prevents predicting the explosion precisely.

蒸汽爆炸是一个综合的多相流现象，包括粗混合、触发、传播和膨胀四个阶段，目前蒸汽爆炸过程中的机理还未被完全了解，这阻碍了对蒸汽爆炸现象进行准确预测。

When pressure drops to 245 psig, a portion of the liquid is passed through a pressure buildup coil which vaporizes the liquid in the coil, and the resultant vapor is sent to the tank's vapor space until a tank pressure of 255 psig is attained. In isolated

当压力降到245 psig时，部分液体流过一个压力积累蛇管，蛇管使其内部的液体蒸发，产生的蒸气送到容器的蒸气空间，直到容器压力达到255
