相变

System uses atmosphere as low temperature heat source.It imbibes heat from atmosphere by evaporation of the refrigerating medium in vaporizer and transfers the heat to phase change materials by heat transfer unit then transfers the heat to cool water from cool water pipe.

它利用空气作为低温热源，由蒸发器内制冷剂的蒸发来吸收空气中的热量，通过传热盘管将热量传递给相变储能材料，获取盘管承压，使贮罐形状不受压力容器限制贮能。

The results show that grains at core are coarser and deformation bands are observed at surface,while microstructure both at core and at surface is composed of bainitic ferrite laths with high dislocation density and interlath cementite or residual austenite.Good uniforinity in h...

结合NQP钢连续冷却时的相变特点，分析其截面硬度波动在±1.5HRC内的原因在于其有较好的贝氏体淬透性，模块整个截面上都得到了均匀的贝氏体组织，贝氏体板条宽度和位错密度的差异使得其表层硬度稍高于心部。

This research is a new low cost method of producing abrasive grit. It is to put the iron ore concentrate, coal powder, hydrated limed and addition agent together to make coal mixed pellet in prior which is rapidly auto-reduced in high temperature and kept about 10min above 1350℃, and then furnace cooled. The 2CaO·SiO2 of slag phase change、volume increase and natural bloom in reduction process. Finally we obtain no-slag abrasive grit through screen separation , in which the iron yield can be above 90%,the sulfur content can be below 0.05% and carbon content is lower than 4.0%.

本研究是一种全新的低成本生产铁粒的方法，它是将铁精粉、煤粉、消石灰和添加剂预先制成球团，在高温下迅速加热还原，在1350℃以上保温10分钟后随炉冷却，渣相中2CaO·SiO2在冷却过程中发生相变，体积膨胀而自然粉化，通过筛分便可以得到不含炉渣的铁颗粒，铁的收得率在90%以上、S≤0.05%、C在4.0%左右。

Not the transformation stress but the initial toughness is the controlled factor for the roughening behavior of free surface during plastic deformation. This phenomenon is discussed in terms of geometrical and physical effect of plastic deformation.

而且初始表面初粗度，而不是相变应力是控制表面粗糙化速率的主导因素；用变形的几何作用和物理作用对此进行了解释。

The measurement of the steam quality is very difficult because steams phase change and complex flow model.

由于流型的复杂性和汽、液之间的相变，干度的测量非常困难。

Different sulfurizing pressures can result in microstrain variations of phase transformation, spot-defect quantity and surface-defect quantity, and then can result in the change of optical absorption properties in the FeS2 films.

硫化压力的变化导致相变微观应力、点缺陷数量及面缺陷比例的变化，进而导致FeS2薄膜光吸收性能的变化。

The MgO melting simulations appears to validate the interpretation of superheating of the solid in the one-phase MD simulations.

However, in the temperature range the material remains body-centered symmetrical structure without finding long-term structural phase transition.

然而在该温度范围内该材料还是体心对称结构，没有发现任何长程结构上的相变。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.
