通过模拟实验和实例对断层垂向封闭的差异性进行了研究,表明由于封闭空间变化造成同一条断层垂向封闭性在空间上存在着差异性,由于封闭条件和机理演化造成同一条断层垂向封闭在时间上存在着差异性,由于封闭对象改变造成同一条断层垂向封闭能力存在着差异性,在相同条件下,同一条断层垂向封油能力强于垂向封气能力。

It is very similar between the secretion of rat pancreatic β cells and gonadotropes in general. Their secretions is also very similar to those observed in other endocrine cells, such as adrenal chromaffin cells. This study further proved that the three phasic process of secretion are ubiquitous.

虽然具体的分泌特性有所不同,但大鼠胰腺β细胞与垂体促性腺激素细胞的分泌情况在总体上很相似,这与前人在其他细胞上的发现也非常相似,本文的实验进一步证实了这种三个阶段的分泌过程和机制在不同的细胞中是普遍存在的。

We assumed that after the PACl〓 was dosed into water, its hydrolysis-aggregation-precipitation process combined the most popular"core-link"or hexameric ring scheme and the more recent model of polynuclear formation involving a typical specie of tridecameric,〓. The integrate pattern can nicely explained the phenomena.

另外,研究表明,PACl中预制的Alb形态和铝盐在混凝过程投加入水后形成的Alb形态在稳定性上有很大的区别,这无疑是由于它们的化学结构上的不同造成的,推测铝盐在投加入水后,其水解聚合过程按&六元环&模式〓和&核环&模式〓结合进行,这种综合模式可以很好的解释实验中的现象。
