近年我爱画的人体也是基于这样一种感悟——浑圆、丰满、富有曲线的人体呈"弧线"、"圆形"，外框则是"直线"、"方形"，再配以各种代表生命的果实，比如"石榴"、"莲蓬"、"苹果"一类，其造型皆呈"圆"或"半圆"的"放射状"，插在或放在"曲线"或"圆"或"半圆"或"圆中见方"的瓶里、盘里、罐里。

Based on the natural gamma log curve s of acid tuff and clay rocks of acid volcanic events,the author here queries the arguments that radioactive intensity of sedimentary strata will grow with the increasing argillaceous materials and that the natural gamma value and the empirical equation can be used to calculate contents of argillaceous materials.

根据酸性凝灰岩和酸性火山事件粘土岩的自然伽马测井曲线，对当前流传的"沉积岩层的放射性强度随泥质含量的增加而增高"的概念和用自然伽马值及经验公式求泥质含量提出质凝。

First the math theory of machining simulation is studied, and the set structure of NC machining simulation system whose components, including time, input, output and so on, are defined. Hereby we set up the hierarchy structure, the logical structure, the static model and the dynamic model of simulation system. The construction method of sweep entity of cutter and rotation parts is researched, and their differential geometry invariants are calculated. NC code is unscrambled, and the recursion division arithmetic of time segment is put forward, which is the driven data of the movement or rotation parts. The CLDATA should be interference-free. To examine if there is interference between cutter flank and the work piece, an arithmetic that discussed the existence of intersecting curve between them is put forward. To examine if there is interference between two turrets, an arithmetic that discussed the existence of intersection set between two polygons is put forward.

首先研究加工过程仿真的数学基础，然后定义数控加工仿真系统的集合结构及时间集、输入集、输出集等概念，建立加工仿真的层次结构和逻辑结构，阐述双刀车削仿真系统的静态模型和动态模型建立方法，分析刀具扫描体和旋转部件扫描体的建立方法及其微分几何性质；研究NC代码解读技术和双刀加工时间段递归子分划技术，为驱动各仿真单元作数据准备；通过讨论后刀面和工件表面交线的存在性判断刀具后刀面与工件间是否干涉，通过求多边形的交集判断刀架与刀架是否干涉。
