Low-temperature viscosity of lube oils mixed with paraffinic base oil and naphthenic base oil at different mass ratios has been tested by experiments.

本实验测定了由石蜡基油与环烷基油按不同质量比例混合后所得油样的低温运动粘度。

Impact of composition upon the cold flow properties for biodiesel was investigated with gas chromatography-mass and cold filter plugging point tester based on the theories of molecular structure and crystal growth. Biodiesel may be considered a pseudobinary mixture consisting of components, with high-melting-point saturated fatty acid methyl esters and with low-melting-point unsaturated ones.

从分子结构出发，根据结晶理论，应用气质联用仪和低温性能测试仪研究生物柴油的组成对低温流动性的影响，为改善生物柴油的低温流动性提供理论指导，并提出生物柴油是伪二元混合物（高熔点的饱和脂肪酸甲酯和低熔点的不饱和脂肪酸甲酯）的观点。

Surface-treated aluminum hydroxide and magnesium hydroxide mixture, linear low density polyethylene and polyethylene grafted by maleic anhydride were melt-kneaded and extruded to produce a flame-retardant masterbatch, and then was extruded with polyamide 6(PA6) to yield PA6/SAMH/PE(50/30/20 by mass ratios)ternary composite.

采用表面处理过的氢氧化铝与氢氧化镁混合物（质量比2：1）、线型低密度聚乙烯、马来酸酐接枝聚乙烯共混挤出制成母料，然后与聚酰胺6(PA6)共混挤出即母料法制备了PA6/SAMH/PE三元复合材料。

In the dry sliding experiments of composites, friction coefficients decreased with the increase of load. Plastic deformation happened in the worn surface where Fe element was found, so PAM micro-fiber supported part of the load and prevented the further deformation. On the condition of high speed and high load, the worn surface of PAM1/nylon 6 composites was nearly melted and formed comparative uniform transfer on the surface of steel, which accounted for the rather low wear mass loss. The infrared analysis showed that the a small quantity of transition of crystal form from α into γ of nylon and its composites happened during the friction because of the high temperature and strong sheering strength.

通过对复合材料耐磨性能研究表明：复合材料的摩擦系数随载荷的增加而逐步下降，且磨损表面有明显的塑性变形；从能谱分析结果来看，复合材料表面有Fe的存在，表明PAM微纤承受了部分载荷，并阻止了基体的进一步塑性变形及粘着转移；在高速高载时，PAM1/尼龙6磨损表面处于粘流态，并在钢环表面形成了连续的转移膜，表现出较好的耐磨损性能，且在高温和强剪切力的作用下，材料基体发生了少量的α晶体向γ晶体的转移。

The PSC was a rounded or elliptic mass in the lung. It had rim enhancement and irregular low hypodense areas in the center after contrast-enhanced CT, lobular sign and spiculated sign.

肺内圆形或椭圆形较大肿块，增强扫描肿块呈不规则环状强化，中央显示不规则密度减低区，酷似肉瘤的CT表现，而其边界不甚规则，边缘不光整，有分叶、毛刺等浸润表现时应考虑为肺肉瘤样癌之可能。
