一辆汽车加满油后可行驶n km，有若干加油站，设计有效地算法，指出应在那些站加油，是得加油次数最少-Fill up the car after driving an n km, there are a number of gas stations, design and effective method that should be in those refueling stations, is the least number of very filling

说明：  三轴代码颗粒流问题是众多工农业生产领域中的常见问题，然而人 们至今对颗粒流机理认识不深。目前一种基于离散元的数值模拟方 法被用以模拟和分析颗粒流问题，研究实践表明该方法是散体力学 分析的一种有效的工具，PFC 3d离散单元法在岩土工程真三轴中使用广泛。(Particle flow is a common problem in many fields of industrial and agricultural production Up to now, the mechanism of particle flow is not well understood. A numerical simulation method based on discrete element The method is used to simulate and analyze particle flow problems. The research practice shows that the method is granular mechanics PFC 3D discrete element method is an effective tool for analysis, which is widely used in true triaxial analysis of geotechnical engineering.)

Delphi把数据库数据转换成SQL插入语句，实现的功能：读取字段列表，读取数据表列表，读取数据库列表，根据数据库参数连接数据库，取本机机器名，转换成SQL插入语句。界面使用了控件，不用的可自己删除。

基于FFT的快速SAR分布目标回波模拟算法. 大面积分布目标的合成孔径雷达(SAR)回波模拟需要大量的运算，文中提出了一种合成孔径雷达回波模拟的快速算法，算法利用时域插值和FFTl’来缩减运算量，对于大面积目标回波模拟时，该算法有很高的效率。文中详细分析sinc函数插值所带来的误差以及补偿方法，并在次基础上提出了一种利用增采样插值方法，该方法以增加少量运算为代价，使得模拟精度的大幅度提高。文中比较了传统方法和基于FFTl’的快速SAR分布目标回波模拟算法的模拟结果，证明了这种快速算法确实行之有效。(The simulation of distributed targets is very important to the design of synthetic aperture radar(SAR)sys- tems．Since the end product is SAR images，the echo of SAR signals needs to be simulated and then processed form SAR images，an d the parameters needs to be measured and the perform ance of the images should be，an d then evaluated．The designing parameters of SAR could be adjusted to meet the requirement of users before developing SAR systems，specially in space—bome SAR systems．Th e simulation data is also needed during the developing an d debugging of a space—borne SAR real—time processor．Another purpose of simulation is to supply a great deal of simulation imag es to train image usors of space—bo rne SAR before it launch．)
