Methods 140 adults patients with TBSA between 2%~48%(children 1%~10%) and deep-II facial burn wounds, were randomly divided into 3 groups.One group was served as the experimental group receiving comprehensive treatment including Dermabrasion,scrape scab,tangential excision and then covering with allogeneic skin.One group was served as the control group I receiving tangential excision treatment and covering with gauge containing iodide.The other group was served as the control group II receiving treatment with SD-Ag.

选择140例成人烧伤总面积2％～48%（儿童1％～10%）、头面部以深Ⅱ度烧伤为主的患者，随机分为三组，试验组于伤后2～3天行磨削、搔刮、削痂综合治疗，覆盖异体皮保护创面；对照手术组同期行单纯削痂，0.5%碘伏油纱包扎创面；对照换药组用SD-Ag霜进行换药治疗。

But with its variety and specialization , three-axial non-instaneous envelope method had not meet needs. So four-axial non -instaneous envelope method was set forth firstly in this article, which is based on three-axial non-instaneous envelope and spiral rod compressor rotator speciality.

然而随着螺杆应用范围的扩展，螺杆型线不断复杂化、多样化，三自由度无瞬心包络铣削法已不能满足部分型线的加工要求，为此本文在三自由度无瞬心包络铣削法的基础上，针对螺杆压缩机阴阳转子的特性，在国内首次提出四自由度无瞬心包络铣削螺旋曲面的新方法，赶超国际螺旋曲面加工技术水平，具有重要的理论和现实意义。

The soil cutting experiment indicates that the interior friction angle and the shear intensity of soil is reduced;and the maximum principal stress is decreased due to the vibration load;it induces the decrease of digging resistance.

从理论上研究了振动掘削岩土的减阻机理，土壤剪切试验结果表明，振动载荷能够使土壤的内摩擦角变小、抗剪强度下降、最大主应力值减小，从而导致挖掘阻力降低；对土壤在静态载荷和振动载荷作用下的失效过程进行了对比仿真实验研究，可知土壤在振动加载的条件下强度显著下降，并提前于相同条件的静态加载而破坏，同时跟踪X方向的载荷发现，振动掘削最大掘削阻力可降低50%。

A precision solution of the moment of inertia of a lead screw's crosssection was obtained by interpolation polynomial and numerical integral method.

在精密长丝杠的磨削过程中，由磨削力、磨削热和砂轮磨损所引起的被加工丝杠的螺距误差已不可忽略。

Invar 36 is a kind of low expansion alloy, and it is difficult to machine because of its plastic, ductility and low heat conductivity. During Grinding, the part surface is easy to burn and wound for high grinding temperature and wheel adhesion.

Invar 36是一种低膨胀合金，其塑性大、韧性高、热导率低，磨削时所产生的磨削力大，磨削温度高，工件表面易于烧伤和划伤，对砂轮的粘附较严重，属于典型的难于加工材料。
