Description: 本报告主要介绍了微机原理与接口技术的应用之一——交通灯控制器的设计与实现，主要是模拟十字路口的红绿灯，还介绍了交通灯控制器的原理以及电路接线，其中主要用到的芯片有可编程并行通信接口芯片8255A。在设计中所用到的编程语言是汇编语言，延时采用的是软件延时（即通过汇编指令）。设计所用到的备是由西安唐都科技仪器公司生产的TD-PIT+实验系统一套。在实验室将汇编程序调试通过后即可看到设计的结果。-This report introduced the Microcomputer Principle and Interface Technology, one- traffic light controller design and realization of the simulation at the crossroads of major traffic lights, traffic lights also introduced the principle of the controller and the circuit wiring, the main use The chip has a programmable communications interface chip parallel 8255A. Used in the design of the programming language is assembly language, delay is used in software delay (that is, through compilation of instructions). Preparation of the design used by the Instrument Science and Technology Garden have produced TD-PIT+ a set of experimental system. In the laboratory testing will be compiled after the adoption of procedures designed to see the results.

Description: 目前三角网是进行精细地形表达最好和最常用的方法，因此本文讨论利用三角网法来建立露天矿的精细DEM模型。由于露天矿复杂特殊的地形特征，在建模过程中应充分考虑相应的约束条件，否则会出现台阶被削平等现象。构建不规则三角网的方法可分为分而治之算法、逐点插入算法和三角网生长算法。各种算法各具优缺点，结合矿区的实际情况，本文采用一次性约束三角网生成算法，经过空间数据提取、拓扑关系建立以及空间索引建立，最终建立起边界约束线以内的约束不规则三角网。-At present, triangulated irregular net is the best method of fine landform expression, so the paper discusses applying triangulated irregular net to establish fine DEM of open-pit. Because of complicated landform characteristic, corresponding constraint condition should be considered in building model process, otherwise it will appear phenomenon that flight of steps is cut. The method of triangulated irregular net establishment is detachable for divide and conquer algorithm, piecemeal intervene in algorithm and triangle net growth algorithm. The various algorithm has excellence and shortcoming respectively, combined with the mining area actual situation, this paper adopt the constrained triangulated irregular net once generation algorithm, through spatial data extraction, topological relations generation and spatial indexing generation, constrained triangulated irregular net is generated within boundary line at last.

Description: 从横截面图来看，坑底成阶梯状，由从左至右的 1..N 个的平面构成（其中 1 ≤ N ≤ 100,000），如图：
＊ ＊ :
＊ ＊ :
＊ ＊ 8
＊ ＊＊ ＊ 7
＊ ＊＊ ＊ 6
＊ ＊＊ ＊ 5
＊ ＊＊＊＊＊＊＊＊＊ 4 <- 高度
＊ ＊＊＊＊＊＊＊＊＊ 3
＊＊＊＊＊＊＊＊＊＊＊＊＊＊ 2
＊＊＊＊＊＊＊＊＊＊＊＊＊＊ 1
平面 ｜ 1 ｜2｜ 3 ｜
每个平面 i 可以用两个数字来描述，即它的宽度 Wi 和高度 Hi，其中 1 ≤ Wi ≤ 1,000、1 ≤ Hi ≤ 1,000,000，而这个坑最特别的地方在于坑底每个平面的高度都是不同的。灌水点设在坑底位置最低的那个平面，每分钟灌水量为一个单位（即高度和宽度均为 1）。随着水位的增长，水自然会向其它平面扩散，当水将某平面覆盖且水高达到一个单位时，就认为该平面被水覆盖了。
计算每个平面被水覆盖的时间。
输入的第一行是一个整数 N，表示平面的数量。后N 行上分别有两个整数，分别表示平面的宽度和高度。-From the cross-section view, bottom is stepped from left to right 1 .. N from a planar configuration (where 1 ≤ N ≤ 100,000), as: i each plane can be used to describe the two numbers that its width Wi and height Hi, where 1 ≤ Wi ≤ 1,000,1 ≤ Hi ≤ 1,000,000, and this is the most special place pit Bottom height of each plane is different. Irrigation point located at the lowest position of the flat bottom of the pit, irrigation amount per minute is a unit (ie, height and width are both 1). With the increase in the water level, the water will naturally diffused to other plane, a plane will be overwritten when the water and high water reaches a unit, they think that the plane is covered with water. Calculated for each plane is covered by water time.

Description: Certain wastes are preferably managed at a community level. Some household
items do not decompose and can cause injury if not properly disposed
of. For example, neither glass nor plastics can be used in composting, and
plastic gives off poisonous fumes when burned. Bones and metal items do
decompose, but the process is very slow batteries contain toxic chemicals.
Bones, metal objects and broken glass can also be thrown into a latrine pit,
but only if the pit is not going to be reused.-Certain wastes are preferably managed at a community level. Some household

Description: A communal refuse pit is simply a pit dug near the community compound
and filled with general refuse. The pit should not be located close to a water
source, because toxic chemicals could leach into the water.
The disposal site itself should be fenced off to prevent access by scavenging
animals. At the end of the day, new waste should be covered with a layer
of clean soil 0.1 metre deep. When the pit is full, the waste should be covered
with a final layer of soil to prevent flies from breeding.

Description: The management of the slopes in an open pit mine depends, amongst other things, upon
the assessment of the stability of these slopes. The recognition and analysis of the
different modes of failure are the main issues that will be addressed in this paper on the
fundamentals of slope design. A critical component of any stability analysis is estimation
of the strength of the rock mass and the discontinuities which control sliding and this
issue will be discussed in some detail. Other topics, such as the creation of reliable
geological and groundwater models and the assessment of risk and economic factors, will
be dealt with by other speakers at this Symposium and in the “Guidelines for Open Pit
Slope Design”.
