蒸汽处理

The conformation of disulfide bonds, secondary structures, crystallinity and α-crystallinity of the cashmere fiber are changed after the cashmere yarn is steamed above 120℃ in relaxed and stretched state or crabbed at 98 ℃, 130℃ for different time, which is firstly found out. These structure changes of the treated cashmere fiber are related to temperature, time, and moisture content and tensile during heat treatment.

The methods of this study were to use the heat treatments included hot air, hot water and steam to prevent decay. We measured the temperature in 5 mm depth of the surface on sweet potato in heating treatments and also used COMSOL Multiphysics to simulate the process and to predict surface temperature that was undetectable during heating process to insure the effeteness of heat treatments. After heating treatments, sweet potato were stored in cold rooms at 13~15℃ and 85~100%.

The measurements demonstrated that the steady state diffusion coefficient parallel to panel surface was more than 10 times as large as that of perpendicular to panel surface.

无论是静态，还是动态扩散系数，刨花经高压蒸汽处理之后的板都有较小的值，这说明蒸汽处理后板子的吸水性能得以改善。

At the same time, the improvement suggestions for the slag transportation and steam treatment etc are put forward.

同时，对渣处理系统的水渣运输、蒸汽处理等遗留问题提出了改进建议。

The glueyness of chips was increased and particleboard resin content could be decreased by 1-1. 5% because of the increase of the free radical concentration of chip surfaces.

结果表明用蒸汽压力1.275N/mm〓的蒸汽处理5min后的刨花表面自由基浓度均提高了，这样有利于刨花的胶合，并能使施胶量减少1-1.5%。

For sulfated sorbent of lime treated by 400～800 ℃ steam, sulfate was the main product at 400～800℃. A fixed bed reactor was developed.

它的400～800℃蒸汽处理后的硫化样品，脱硫温度在400～800℃之间，硫酸盐是主要产物。

Furthermore,vapor treatment has no negative effect on environment,therefore it is a promising wood modification method for pencil industry.

且蒸汽处理法不污染环境，因此是一种有着良好前景的铅笔用材改性方法。

Wanted to know exactly which chemicals were behind the heartburn. So they took extracts of two coffee blends—one light, one dark—and their steam-treated counterparts.

于是他们对两种咖啡（一种未经烘培，一种经过深度烘培）的提取物及它们相对应的经过蒸汽处理的提取物进行化验。

Infrared spectra demonstrated that the hemicelluloses in steam-treated chips were less than that in untreated chips. This is one of the main reasons why steam treatment could improve particleboard stability. We found that the reduction of the hemicelluloses in Birch chip was more than that in Spruce chip under the same condition of steam treatment.

用红外光谱对蒸汽处理后刨花中成分的变化进行了分析，发现处理后的刨花中的半纤维素含量减少了，羟基减少了，这就是蒸汽处理能提高刨花板的尺寸稳定性的主要原因之一。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
