D. N big mouse model was successfully made by adopting single side kidney cutting with induction, then by 24 week continuos observation on the change of various values of kidney and function, through testing of immunity florescence, electro-scope and optical scope, what we can see from model group is that typical kidney small cell got hardened by knot, and discarded, and dead, also small tube withered, small cell of on base film got thick, cell capsule wall was fibred, and base film got double layered.

实验研究采用单侧肾切除加以链脲佐菌素诱导，成功地复制出糖尿病肾病大鼠模型，对其肾脏结构和功能的改变各项指标，连续进行24周动态观察，并进行免疫荧光、电镜、光镜检测，结果表明：糖尿病肾病模型组可见典型的肾小球节段硬化、废弃、坏死，有大量蛋白管型，肾小球管糖元空泡沉积及脂肪滴，肾小管萎缩，肾小球基底膜明显增厚，球囊壁纤维化，基底膜双层化，有一例结核性肉芽组织及钙化等病理变化。

In this paper, preliminary FDS fire chamber to simulate the flue gas generated through the corridor adjacent to the room near the migration laws, an analysis of indoor air flow field and the movement of smoke layer, and through the simulation of fire scenes, in a simple form of visual dynamic display of the entire process of fire, in the simulation process to obtain more accurate fire-related parameters such as temperature distribution, gas flow and heat radiation, and analysis of simulation results through the fire chamber of the flue gas migration characteristics, results showed that the chamber in the absence of fire smoke control measures, the process of the spread of smoke filled the first chamber is at the top, with the passage of time, the proliferation of slowly downward until the entire chamber is full, and then through the corridor smoke quickly spread to the nearby chamber.

本文运用FDS初步模拟了腔室火灾产生的烟气通过毗邻的走廊向附近房间迁移的规律，分析了室内空气流场和烟气层运动状况，并通过对火灾场景的模拟，以简单直观的形式动态显示出火灾发生的全过程，在模拟过程中获得较准确的火灾相关参数，如温度场分布，烟气流动及热辐射等，并通过模拟结果分析腔室火灾的烟气迁移特性，结果表明着火腔室在无防排烟措施的情况下，烟气扩散的过程是首先充满腔室顶部，随着时间的推移，慢慢向下扩散，直至将整个腔室充满，然后烟气通过走廊快速向附近腔室蔓延。
