Methods CHD patients were proved by coronary arteriongraphy. 64 patients with type 2 diabetes in combination with CHD were enrolled in group A and 98 patients with simple CHD served as group B. Patients of group A were subdivided into 3 groups based on scalar of the stenotic coronary artery, viz 1 rarnus, 2 rami and 3 rami affection groups, and urinary albumin level was determined. In group A, age, course of DM, BMI, BP, BS, GHbA1c, blood-fat, UAL serving as iv, and affection sum and stenosis index serving as dv, ran polynary gradual regressive analysis.

随机选取经冠状动脉造影确诊的冠心病患者，其中2型糖尿病合并冠心病患者64例为A组，单纯冠心病患者98例为B组，比较两组患者的临床资料和冠状动脉病变情况。A组患者根据冠脉病变支数分为3个亚组，即l支、2支、3支病变组，比较亚组间的尿白蛋白水平；A组患者以年龄、体质量指数、糖尿病病程、血压、血糖、糖化血红蛋白、血脂、尿白蛋白为自变量，分别以病变数、冠脉狭窄指数为因变量进行多元逐步回归分析。

试验结果表明：冻融循环过程中电阻率与冻融变形的变化是实时的、完全同步的，利用电阻率特性研究冻融过程土体结构变化是可行的；每次冻融冻土电阻率随着冻融次数增加呈指数关系减小，融土电阻率随冻融次数增加呈指数关系增加；每次冻胀量与融沉量随冻融次数的增加而减小，平均干密度随冻融次数增加而增加，并且经过5次冻融循环后冻胀融沉量和干密度均趋于稳定。

Based on the meteorological observation data and the vegetation index data in Yulin,synchronousness relationship of vegetation index and sandstorm activities were analyzed,the results indicates that,Intra-annual changes of vegetation covers and sandstorm activities are evidently inverse synchronous,which may conduce to reducing the wind-break and sand-fixing function of vegetation.

以榆林市为例，利用气象观测和植被指数数据，对植被覆盖与沙尘暴活动发生的时间同步性关系进行了分析，结果显示：植被覆盖与沙尘暴活动存在着年内的时间不同步性，严重制约植被防风固沙生态功能的发挥；沙尘暴日数与植被指数的年际变化呈现出反相关系证明了植被覆盖对沙尘暴活动具有很强的防护作用。
