The static high-pressure experiments show that enstatite transforms to perovskiteSiO〓 at high pressure, so perovskiteSiO〓 is thought to be one of the main compositions of the lower mantle, but if it could keep the perovskite stucture in the whole lower mantle condition, there are still different opinions.

静高压实验研究表明，高压下顽火辉石将转变为钙钛矿型SiO〓，于是人们将钙钛矿型SiO〓列为下地幔的一种主要候选组分，但对于钙钛矿型SiO〓在下地幔压力(24-136GPa)和温度条件(约2000-5000K)是否保持单一相态的问题，目前尚存在不同意见。

Hepatic sinusoid capillarization plays an important role in occurrence of portal hypertension. The fenestra of endothelial cells in hepatic sinusoid reduces and the diameter of fenestra decreases. The formation of basement membrane impaires the substance exchange between blood and hepatic cells,which results in oxygen deficiency, metabolic product accumulation and cell necrosis.

肝窦毛细血管化在硫代乙酰胺诱导的肝硬化门脉高压发生中起重要作用，肝窦内皮细胞窗孔减少并减小，内皮细胞下基底膜形成使肝细胞与外界物质交换减少，导致细胞缺氧、代谢产物聚集，肝细胞坏死，最终导致门脉高压的发生。

As to the work about theory analysis, at first, the paper describes the atomizing and humidifying process of the centrifugal nozzle with firing pin type, high pressure and little aperture and liquid physical properties. Later, combining with the structure characters of this kind of nozzle, the paper studies on the theory of the atomizing and humidifying process by three phases, which is water film forming phase, water film falling into pieces phase, and heat and mass transfer between water and air phase in turn.

理论工作方面，首先描述了撞针型高压小孔径离心式喷嘴的雾化加湿过程和液体的物理性质，然后结合撞针型高压小孔径离心式喷嘴的结构特点，将其雾化加湿过程分三个阶段进行机理上的研究，这三个阶段依次为液膜形成、液膜初次破碎及二次雾化、水与空气的热湿交换。
