查询词典 drying agent

According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.

通过扫描电镜观察发现，小径木落叶松的径壁具缘纹孔数目较多，且多具纹孔膜，小径木落叶松除在树脂道中含有树脂外，在一部分管胞胞腔内以及一些木射线细胞中也含有树脂，在产生缺陷的小径木落叶松锯材中，连续加热方式下锯材的开裂缺陷最为严重，波动2时次之，波动6时几乎没有开裂现象；小径木大青杨心材导管中的层状浸填体含量较多，且径壁具缘纹孔较为密集，管间纹孔呈互列方式，绝大多数纹孔具有纹孔膜，干燥后的小径木大青杨锯材均有不同程度的皱缩现象产生，其中连续加热干燥试验锯材的皱缩现象最严重，波动2时次之，波动6时干燥试验锯材的皱缩缺陷最小。

Based on the raw material conditions of pelletizing process at Ma Steel the process parameters, such as bed depth of grate, temperatures of updraught drying , downdraught drying, preheating and roasting in oxidized pellet production were studied with a grate-kiln simulator.

基于马钢球团原料条件，在模拟试验装置中研究了链箅机—回转窑氧化球团生产的料层高度、鼓风干燥热风温度、抽风干燥热风温度、预热热风温度和回转窑焙烧等工艺参数。

From the "" to wet-membrane "" viscostty dry film evolves, you can see any of the oils or gloss drying or curing process must go through the process of viscosimetry products, that is solid oils or varnish, mostly due to its own power, but was decoratine adhensive in coated packaging business card printing and membership card making products surface, it is not possible to immediately contiguous becomes solid continuous gloss films, only up to a certain conditions in order to complete all of the varnish coating to the drying process of prefilming.

从"湿膜"到"干膜"的粘度变化过程中，可以看到：任何一种的底油或光油的干燥或固化过程必然都要经历该产品粘度的变化过程，即是固体的底油或光油，由于其本身多为粉末状，但在装饰粘附在被涂布的包装制卡和会员卡制作制品表面后，还不可能立即就形成连续进行变成为固体连续光油薄膜的过程，只有达到一定条件才能完成全部的由光油涂布到干燥成膜的过程。

Natural volatilization drying, needs at least 30 minutes surface drying,weather condition and printing condition.

自然挥发干燥，表干约需30分钟，实干24小时以上(因气候及印刷环境不同有差异)。

Blow drying causes a "flash drying" effect that not only removes the surface moisture but also removes water that is bound to the hair, which is called water of hydration.

吹发导致快速干发的后果，会使你的头皮表层和头发必须的水分流失，这就是所谓的结晶水。

In the steam-jet heat pump steam and water is the working substance, so condensing temperature is higher than the refrigerant normally using in heat pump. It is suitable for all kinds of species wood drying in different temperature, especially high temperature drying.

本文是将蒸汽喷射式热泵技术应用于木材干燥，可以降低木材干燥的能耗，提高干燥质量和经济效益：蒸汽喷射式热泵以水蒸汽为工质，因此冷凝温度可以较高，适用于各种木材在不同的温度下的干燥以及高温干燥。

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。

Objective: Study on the effects of different drying methods on Poria cocos, and determinating the best drying temperature of Poria cocos.

目的：考察不同干燥方法对茯苓饮片的影响，确定饮片的最佳干燥温度。
