切下

When to get the coefficients of polynomial directly,the ill-conditioned matrix may be produced and effect the precision of result.Using orthogonal polynomial can avoid this problem.This paper introduces 4 orthogonal polynomial.In our discussion,it is proposed to use Chebyshev polynomial and Legendre polynomial,they are easier to sa...

讨论4种常用正交多项式在拟合卫星轨道与时间函数时的适用性；通过计算实例说明利用切比雪夫多项式和勒让德多项式做数据拟合时具有很高的精度；分析得出评定多项式拟合数据精度的适用阶数，实际应用中可降低工作量，提高计算效率；最后讨论同一多项式阶数下不同历元数对拟合结果的影响。

Results By using optical microscope,the neurocytes of hippocampus in experimental group were observed to denaturalize,tumefy,destroy and disappear.And under electron microscope,the karyon was irregular,nucleoles deviated,chondriosome tumefied,crista collapsed,membrane was damaged,substance cavitated.Such changes were more evident with the increased paroxysm of epilepsy,the parameters between control group and operation group had no difference（P＞0.01）.But make a monofactorial variance analysis among cells' number,area,circumference and integral optical density in different groups,it showed that there were significant differences between optional two groups（P.01;at the same time,the more serious injury in hippocampus,the more powerful GFAP immunoreaction was.

结果： 实验组海马区光镜下可见神经细胞变性、肿胀、坏死及神经细胞脱失改变，电镜可见细胞核形态不规则、有切迹、核仁偏位、线粒体肿大、嵴断裂、膜破损和基质空化等改变，随癫痫发作次数增加上述改变越明显，对照组与手术对照组比较，各参数差异无显著性（P＞0.05），将不同组别大鼠细胞数、面积、周长、积分光密度分别作单因素方差分析，不同组别间均差异有显著性（P.01），同时观察到海马区GFAP免疫反应阳性的胶质细胞随海马损伤的加重而GFAP免疫反应增强。

Do not put the board under the naked flame, melted metal, metal sparkles or sun, and never cut or chop anything at the surface of the board.

By using TCN—AN numerical torsion testing machine, the torque of Cast Iron Materials under pure shearing is measured, and its strain is also measured through XL2101B2 static strain meter, adopting method of whole bridge connection. Based on the above experiment equipments and all the measurement results, method of torsion of circular shaft is designed to measure Elastic Modulus of Cast Iron Materials.

通过 TCN—AN数控扭转试验机测量处于纯剪切状态下铸铁试件的扭矩，采用全桥接线法，使用XL2101B2静态应变仪测量铸铁试件的应变，基于以上两种实验仪器及其测量的结果，发展了圆轴扭转法来测量铸铁材料的弹性模量。

My station domain name was registered August 22, but building a station truly is 24 begin, so today just full a month, took a lot of roundabout way, the hope can give the stationmaster friends of begin to learn a few helps, doing station experience to believe friend of a lot of stationmaster knows is very tired, I also send next little deep feeling in this, ah it is good to breathe out ～, claver was not pulled, cut subject.

我站域名是8月22号注册的，但是真正建站是24号开始，所以今天刚好满一个月，走了好多弯路，希望能给初学的站长朋友们一些帮助，做站体会相信很多站长朋友都知道是很累的，我在这也发下小感慨，呵呵～好了，闲话不扯了，切正题。
