Methods: Ninety three female with adiposis were assessed for cholesterol, triglycerides, HDL-C, HDL2-C, HDL3-C, LDL-C and VLDL-C. At the same time the waist circumference was measured from the midpoint between the lower rib and the upper margin of the iliac crest (waistline 1) and the level of umbilicus (waistline 2). The hip circumference was measured at the greatest girth of the gluteus and waist-to-hipratio was calculated (waist circumference/hip circumference).

Analyzing and simulating of the deformation law of the ceramic downspout product after overcoming the shortage of powder material models in the software of MSC. MARC. It shows out the important effects of various factors and the shape of mandril during the process. And it is obvious that the shape of the top mandril has more effects on the process than the bottom.(3) Showing out the important effects of model figure on the flowing of powder and the forming of low-density fields from the analysis. After changing the top of the mandril into spherical shape, an improving model is putting out so that the distribution of stress and strain turns to be even and proper and that the flow rule of powder grains is better.(4) Calculating of the dimensional precision and the cutting ratio of the product and analyzing of the effects of such factors as rubber aging, loading process, mandril, friction etc. on the cutting ratio.

MARC存在的粉末材料模型方面的设计缺陷后，对连铸水口粉末成形件的变形规律及影响因素作用进行了模拟分析，指出芯棒形状对成形件的变形有较大影响，并且芯棒顶部形状与芯棒底部形状相比，对粉末变形有更大影响；(3)分析了成形件出现低密度区域的原因，指出模具形状对粉末流动以及粉末成形件低密度区域的形成有重要作用，提出了密度分布优化改进模型：改进模具顶部形状，并将芯棒顶部设计成球面后，粉末成形件顶部区域的应力、应变分布更加均匀、合理，粉体颗粒流动情况明显改善，低密度区域明显缩小；(4)计算了成形件的尺寸精度及切削率，并指出除模具形状的影响外，充填密度、橡胶模具老化、加载工艺等其他因素对总体切削率也有相当的影响。

The results indicate that multiple reflections are favorable to the increase of depth. When the focal position is above the surface, the absorptive intensity on the front decreases, so the cutting depth decreases. When the focal position is below the surface, the position on the front with the maximum power intensity is downward. The intensity distribution is toward the deeper position, the cutting depth increases. But if the negative focal distance is extremely big, the intensity of the deeper position attenuates sharply with the increase of focal radius and light distances, so the depth deceases.

正离焦切割时，前沿吸收的总激光功率密度减小，切割深度减小；负离焦切割时，最大激光功率密度值的位置下移，使得前沿功率密度分布朝着深部推进，切割深度增加，若负离焦量过大，表面光斑直径和光程增加，更深位置的功率密度减小，切割深度减小；随着激光功率增加、切割速度减小，则前沿弯曲程度减小，被激光直接照射的前沿部位增长，前沿吸收激光功率密度增加，切割深度增加。
