摘　　要：根据蚕茧大小将蚕蛹分组,测其质量、体表面积等值,利用国际标准统计软件SAS的REG、GLM、NLIN过程处理数据。结果表明,蛹体质量与体表面积、相对体表面积特征值间均存在极显著的指数关系,如:质量与体表面积间呈正相关,决定系数达0.8717,模型为y=4.9265xe-0.2288x;质量与相对体表面积间呈负相关,决定系数达0.9493,模型为y=8.9331xe-0.8746x。即蛹体表面积随质量增加而变大,相对体表面积反而变小。其次,纵、横幅、体积等各特征值间的一元关系,质量、体积与纵、横幅,体表面积与纵幅、体积间的多元关系也都达显著或极显著水平。The pupa was divided into different types by the size of cocoon in this test, and the body weight, area of body surface and other eigenvalues were measured. The data analyzed by the REG, GLM, NLIN of SAS software. The results are as follows. First, pupa body weight and area of body surface, relative area of body surface are very significant logarithm relationship. Correlation of body weight and area of body surface is significant, the correlative coefficient is 0. 871 7, the statistical model is y =4. 926 5xe^-0.2288x ; Negative correlation of body weight and relative area of body surface is significant, the correlative coefficient is 0. 949 3, the statistical model is y =8. 9331^xe-0.8746x. It means that when the body weight increase, the area of body surface will come up, but the relative area of body surface will come down. Secondly, unitary correlation of vertical length, thick degree, volume and multicorrelation of body weight, volume and vertical length, thick degree and multicorrelation of area of body surface and vertical length, volume, are significant or very significant.
