These changes have a coherent trend to those of SAS clinical patents, and most changes were more remarkable than the rhubarb root laxation and over-swimming SAS mice models.

实验结果显示，改良型劳倦过度模型小鼠造模后出现脾虚证的典型外观表现，且客观指标改变与文献报导相符，与临床脾虚证患者变化趋势一致。

But only partial changes of rhubarb laxation group and over-swimming group have a coherent trend to those of SAS clinical patents. Our improved over-fatigue method is better than rhubarb laxation method and over-swimming method. Proved by Sijunzi decoction treatment, the mice behave normally. All objective indexes are improved more distinctively than the group that resumes naturally. These prove that the SAS model is made successfully and meets the requirements of judgement for SAS animal model. In this model, SAS is caused possibly by largely released Gas, which results in increased contractile in small intestine, over-exudation of intestine and obstacle in absorption.

在所选的指标中，改良型劳倦过度组小鼠的变化均与临床脾虚证患者的变化趋势一致，且多数指标的变化较大黄组(大黄泻下法塑造脾虚证动物模型)和力竭游泳组(力竭游泳法塑造脾虚证动物模型)明显，而大黄组和力竭游泳组只有部分指标的变化与临床患者一致，因此，改良型劳倦过度法塑造脾虚证动物模型优于大黄泻下法和力竭游泳法。

Detailed description has been given individually to the abnormal colours, lineament and circular structure and image features on the multi-geographycal information composite image. We have studied the ore control effect of circular and lineament structure to the multimetal ore, and come to the point that the Xianghualing region is a complex ore control area by circular and lineament structure.Therefore, we build a remote sensing imag model for ore field in the region. Within the circular structure, the northwest lineament crosses the northweast lineament and forms frames that control the metal ore distribution. According to the features of the found deposits and their coherent image, we conclude that there are two symbols for ore looking.
