After years studying the microscropic structure of plants , he proposed his cell theory contributions to phytogenesis ( 1838 ) , in which he stated that the various plant structures are all composed of individual cells 经过多年对植物显微结构的研究，他在1838年发表了的《植物发生论》中提出了细胞学说，指出细胞是构成植物体各种结构的基本单位。
Electrical resistance , dsc , xrd and tem measurements were used to study the crystallization , phase transformation and microstructure of tini thin film . in addition , a new synthesis method was done to prepare pbtio3 / tini composite film 磁控溅射方法制备的tini非晶薄膜必须在450以上进行晶化处理，晶化过程伴随有电阻的异常变化；电阻法比dsc法能更精确的反映tini非晶薄膜晶化过程显微结构的变化。
So , the ideal mixture model is adopted to estimate their densities , volume velocities , wave impedances , specific heats , gruneisen parameters and hugoniot coefficients . relative research indicates that not only the compositions but also microstructures of the composites affect their physical properties 对复合材料的相组成和元素面分布的分析，以及对其显微结构的观察表明， w - mo 、 mo - ti体系复合材料均可看作简单混合物体系。
It was found that the introduction of ca2 + enhanced the sinterability of the material . the relative density of sintered specimens increase with the content of ca2 + in the composition range of 0 < x < 0 . 3 . it was confirmed that a high relative density can be obtained at relatively low sintering temperatures by using uniform , high surface area la1 - xcaxcro3 powders , which modifies the crystalline structure and microstructure of ceramic specimens 研究结果表明， a位ca ~ ( 2 + )的引入在一定程度上能够降低材料的烧结致密化温度：细小、均匀、高比表面积的粉料能够有效降低材料的烧结致密化温度；烧结温度的降低可以减少la _ ( 1 - x ) ca _ xcro _ 3中液相含量和铬氧化物的挥发，有利于材料晶体结构、显微结构的改善。
Secretic granules in b cell are fairly big , cores are various . there is fairly big gap between the core and the limiting membrane ; the center of secretic granules in a cell exist compact core and there is no gap between the core and the limiting membrane ; secretic granules in d cell are too much , electron density of granules is lower , and there is no gap between the core and the limiting membrane , what ' s more , fairly big chondriosome can be seen in the cell B细胞的分泌颗王晓丽尼罗罗非鱼胰岛显微和亚显微结构的研究13粒较大，芯的形态多样，电子密度差异大，芯与界膜之间常有较大的空隙； a细胞分泌颗粒形态不规则，芯的大小不等，界膜与芯之间无空隙； d细胞分泌颗粒较多，芯的电子密度较低，界膜与芯之间无空隙，此外，胞质内可见较大的线粒体。
