[Documents] 逢山开路模型 DL : 0: 在本问题的求解中，修桥和挖隧道是两个相类似的求解过程，我们将求解过程分为两个部分：第一、对河岸边一固定点，将桥修在处时，求解由起始点到经固定点到居民点的最短路线。第二、如何确定的位置，使得总路线的费用最小。我们分别用了两个模型来进行这两部分内容的求解。模型一、针对坡度的限制，利用小区域内的局部最优来达到全局最优。模型二、列出点有一定的位移时，可以减少的费用的函数方程，然后利用河岸附近等高线较紧密，公路不能沿偏离等高线方向前进的特性，求出减少的费用的条件极值，从而确定最佳修桥地点。最后，我们利用模型一、二的原理对隧道部分的公路做了同样的优化设计，然后得出总的修路费用估计为324万元，较合理。最后，我们对整个做法的误差及合理性做了分析。-in solving this problem, building bridges and two tunnels are dug similar to the solution process, we will be solving process is divided into two parts : the first, on the banks of the river a fixed point of the bridge repair in the Department, from the starting point to solve by the fixed point to settlements in the shortest routes. Second, how to determine the location, making the cost of the smallest general line. We were using the two models, both part of the solution. One model, the slope of the restrictions against use of the local small areas to achieve optimum global optimum. Model 2, listing a certain point of displacement, can reduce the cost of the equation, and then using the riverbank near the contours more closely, not along the highway from contour direction of the character

[Documents] 零工 DL : 0: 1，2，3三个城市每年需分别供应电力320，250和350单位，由Ⅰ，Ⅱ两个电站提供，它们的最大可供电量分别为400个单位和450个单位，单位费用（元）如下表所示。由于需要量大于可供量，决定城市1的供应量可减少0单位～30单位，城市2的供应量不变，城市3的供应量不能少于270单位，试求总费用最低的分配方案（将可供电量用完）。(1, 2, 3, three city each year to 320250 and 350 respectively, power supply unit, an I, II provides two power stations, the maximum power supply which is 400 units and 450 units respectively, the unit cost (yuan) as shown in the following table. Because the demand is greater than the supply available, decided to supply 1 of the city can be reduced by 0 units to 30 units, the supply of city 2 unchanged, the supply is not less than 270 of the city 3 units, try to seek the lowest total cost allocation scheme (the power supply will be exhausted).)

[Documents] LCR-V5.5 DL : 0: 大部分元件需要DIY，所以需要知道元件的参数。因为DIY的元件没有标称技术参数。比如，需要知道谐振器件、检波器件、天线、耳机、变压器等器件的电抗特性。其中，高频参数可以使用Q表解决问题，而低频参数Q表难以测定。为了解决这个问题，笔者认为LCR数字电桥能够胜任。((Most components require DIY, so you need to know the parameters element. DIY components because there is no nominal technical parameters. For example, the need to know the reactance characteristic resonant devices, detection devices, antenna, headphones, transformers and other devices. Among them, high-frequency parameters can use Q table to solve the problem, while difficult to measure low frequency parameter Q table. To solve this problem, I think LCR digital bridge capable. Design goals: 1, it is possible to accurately measure the reactor L, C, R, precision better than 0.5 , if the file manually by calibration accuracy of better than 0.3 2, drawing easy circuit is simple, easy to make, cost should be properly controlled. So that it has more value and amateur DIY research value, and learn details about LCR bridge, the principle by design, DIY. The basic features of the LCR table AD converter Word Count: approximately 1000 words, using the oversampling technology, effective reso))

[Documents] new scan converting scheme and advanced graphics DL : 0: A new scan conversion scheme and memory. This may cause conflicts and reduce the video memory architecture with advanced system performance. graphics for raster scan radar display are proposed in this paper. By taking advantage 2). In order to display the radar signals it is of succession of radar range scan, the necessary to convert form the polar format into Cartesian coordination increments(0 or 1) of Cartesian co-ordinates which match the raster scan every two axial adjacent points are pre- format on the screen. In high rotating rate and high calculated and stored and then the Cartesian transmitting frequency situation, the high speed and coordination can be reconstructed by real time scan converting is difficult. In addition. counting the increments realtimely when artifacts called "dead address." and "moire" will be converted . This new approach works quickly caused by digital scan converting . and precisely and can overcome artifacts in 3). There is contradiction between the versatility visual effects. The advanced graphics flexibility and low cost, compactness. functions of this system greatly improve the display performance , especially the ability of A modularized system which has perfectly solved plotting extracted data. A practical display these problems is introduced in following sections. system based on these principles is developed and implemented . The excellent result 2. System Architecture proves its feasibility and versatility.
