Because of appearing empty aggregates in the time zone (the time zone do not include the information), we only establish the indeterminate grey differential equation according to the approximate condition of the differential equation.

利用灰色微分方程中的最小二乘估计参数：进而得到灰色神经网络初始的权值及阈值，这样使初始的权值和阈值更接近准确值，克服了以往BP网络中初始权值的随机性和不确定性，减少了网络的训练次数，提高了网络收敛速度和输出的精度，为避免网络训练陷入局部极小值也起到了重要的作用。

Researches show that the drive force characteristics of the electric tractor drive system based on series DC motor is close the ideal characteristics, the curves are concave, low speed with constant power, and high speed with constant torque; the electric tractor has large working speed under different shifts, but the extensive coincidence speed shows that the variable ratio of the gear is unreasonable; the maximum climbable gradient of this electric tractor is more than 30%, and does not need frequent shift when working for its extensive climbable gradient; there are many influence factors of continuous working time, which the more obvious factors are working speed and working load, the working time increases with the increase of the working speed and working load.2. Simulation researches on the drive characteristic of the electric tractor.

研究结果表明：基于串励直流电动机(来源：ABC21论文网www.abclunwen.com)的电动拖拉机电驱动系统的驱动力特性场接近理想驱动力特性场，其各挡下的驱动力特性是一组下凹的曲线，低速恒转矩，高速恒功率；同一行驶速度下所对应高挡驱动力大于低挡驱动力，这是由电机的调速特性决定的；电动拖拉机各个挡位下具有较广的稳定作业速度范围，但是各个挡位之间速度重合的范围较多，说明所用变速箱变速比与电动机匹配不合理；电动拖拉机最大爬坡度达到30%以上，并且各挡爬坡度变化范围较广，作业过程中不需要频繁换挡；影响电动拖拉机连续作业时间的因素较多，其中作业行驶速度和作业负荷影响最为明显，作业负荷越大，连续作业时间就越短，作业速度越快，连续作业时间就越短。2、电动拖拉机驱动特性仿真研究。

Direct shot can shoot most of times, movement shot and fill shot cannot shoot at that much. The most shooting happened at normal position. The gap between normal position and non-normal position is closer and closer. The percentage of non-direct confrontment shot far more than direct confrontment shot, and also this percentage is close to each other year by year.

直接射门的进球数量最多，运球突破射门和补射进球数量较少；绝大多数的进球是在正常状态下打入的，正常状态和非正常状态进球占全部进球的比例差距越来越小；非直接对抗射门进球数所占的比例远远大于直接对抗射门进球的比例，但直接对抗和非直接对抗的比例成逐年接近趋势。

The main contributions are summarized as the following.Firstly, assuming demand is segmented by order lead time, a joint pricing and capacity allocation model is formulated considering scenario-based demand. Due to the stochastic discrete variable in the model, robust optimization is used to solve the model. Numerical examples prove our model and method reflect the stochastic characteristics of demand and provide more pratical pricing and capacity allocation policies than other methods of deterministic and stochastic expectation programming methods especially when the capacity is tight.

本文的创新之处概括为如下几个方面：首先，假设制造企业根据交货提前期对市场细分，建立了考虑需求情境的BTO模式下制造企业定价与能力分配的集成模型，利用稳健优化规划方法对此随机模型进行转化和求解，算例仿真表明随机优化规划方法较确定性规划和随机期望值规划方法更好地反映了随机离散需求的分布和波动特征，更加接近实际运作情况；产能越紧张，各类需求的价格差距越大，三种规划方法给出的最优策略差距越大。

A new technique is presented in this paper for frequency estimation of single real sinusoid at a low computational cost using the real parts or imaginary parts of Fourier coefficient s.

提出了一种利用信号离散傅里叶变换系数的实部或虚部来构造频率修正项的新算法，算法只需傅里叶系数的实部或者虚部的最大值附近的3个DFT系数来构造频率修正项，避免了复数运算从而有效减少了运算量，同时算法的频率估计精度接近CRLB(Cramer-Raolow bound)。

Each wife that approachs her can go in spite of oneself her glamour is in hunting, I know, that is the curiosity that brings because of marriage of legend of a rich and powerful family. June 1999, one is called Deng Wendi, little known on all gregarious field China woman, married world-class medium king -- the Moduoke of news group, this big she is very much, rich but the famous man of enemy state, bring her from now on cannot evasive fact -- him Deng Wendi also becomes the news person that has value most, no matter their apiration how, fame and fortune, guess and fokelore always is photograph companion is followed.

每一个接近她的女人都会不由自主地去探求她的魅力所在，我知道，那是因为一场豪门传奇婚姻带来的好奇。1999年6月，一个名叫邓文迪、在所有社交场上名不见经传的中国女人，嫁给了世界级传媒大王——新闻集团的默多克，这位大她很多、富可敌国的闻名丈夫，从此带给她无法回避的事实——邓文迪本人也成为最具价值的新闻人物，无论他们的意愿如何，名望和财富、猜测和传说总是相伴相随。

Cold places like cold stone substrate, transparency, quality nourish, low hardness, gloss strong line better varieties; soft ground nearly frozen to substrate, but the lack of transparency; just manner, then the hardness high, often with quartz quality of sand screw; hard the worst quality, hardness, opacity, gloss weak, often more impurities, and rock in the gravel. 3, defects, including impurities and cracks in the stone.

冻地的底质似冻石、透明度高、质细润、硬度低、光泽强，系较佳品种；软地的底质接近冻地，但透明度不足；刚地，则硬度偏高，常含石英质砂钉；硬地的品质最差、硬度大、不透明、光泽弱，常有较多杂质和围岩中的砂砾。3、瑕疵，包括石中的杂质和裂纹。

These predatory beasts are found all across Outland, often lurking behind rocky clusters and towering escarpments, waiting to pounce on any prey foolhardy enough to wander within striking range of their blindingly fast, razor-sharp claws.

这些肉食性的野兽在外域里处处可见，它们最喜欢埋伏在隐密的岩石堆里或哨塔的壕沟里等待著不知情的猎物接近，然后再用它们迅速和锋利的尖爪一击刺杀猎物。

Macroscopically speaking, in order to compensate for the lake of large French windows, it is recommended to replace direct lighting with indirect lighting, and make artificial lighting as close to the softness of natural light as possible.

宏观看之，整体空间建议以间接光来取代直接照明，让人工光线尽量接近自然光线的柔和自然感，以弥补环境中无法拥有大片落地窗的缺憾；微观选择，灯具建议挑选立灯或壁灯来取代吊灯，一般人会误以为立灯占空间，但其实吊灯最容易让空间中的视觉受到阻断，立灯与壁灯由於倚墙而设，不但无此问题，在小区域的光源控制上更具有灵活的弹性选择。

With the assimilation of dropsonde/QuikSCAT data, the simulated environmental flow becomes more northerly/southerly, resulting in better tracks. The data assimilation also helps to produce better water vapor mixing ratio in the simulations of the Bilis and Mei-yu cases. As a result, the radar reflectivity is better captured in the simulations.

雷达回波强度方面，碧利斯台风及6月中旬梅雨锋面个案之模拟前期同化该两种资料后，有较大的水气混合比，因为有较大的湿度及较多云水含量的缘故，使其模拟有较强的最大回波值，与观测较为接近。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。
