The interplanar spacing and conversion trend of wax crystals are increased from orthorhombic crystals to hexagonal crystals for the colloid and asphaltene existing,showing short-rang.
5%,表现为长程有序;原油组分中胶质和沥青质的存在增大了蜡晶转化成斜方晶型的趋势,使蜡晶的晶面距增大,蜡晶表现为短程有序,这种转化依赖于原油组分的性质和含量;降凝剂降低蜡晶体的有序度,晶面距增大到0。

The α-sulphur stone on the walls of the bubble is discovered and its cause of formation is discussed.
利用Raman探针和加热方法在普通平板玻璃的气泡壁上发现微米级α斜方硫结石,指出这类气泡的成因与玻璃熔体中单质硫的存在密切相关,并认为单质硫主要来源于原料中的含硫化合物在玻璃熔体中的反应产物。
Objective To provide a morphological data for clinic application of the compartments of human trapezius transplantation.
目的为斜方肌亚部肌移植的临床应用提供形态学资料。
Results: The mean area of thicken fascia under trapezius at superior angle of the scapula was about 4 cm×2 cm, with the presence of bursa about 12.
结果:斜方肌位于肩胛骨上角处深面筋膜增厚变白,增厚筋膜平均面积为4cm×2cm。
