Our product includes 4 series , s , c , m , qhm and hongyuan carbon offers specially demanded graphite powder for customers . our anode carbon materials following unique functions : stable internal structure , ellipsoidal , smooth surface , suitable particle distrbution , superior safety and good electrochemical performance 目前我公司生产的锂离子电池用负极材料系列产品包括： s 、 c 、 m及qhm ，公司还可以生产客户的需要订制产品。
Because of its own feature of the structure , ellipsoidal cavity has coupling microwave generated from one of the ellipsoidal center , and plasmas generated from the other ellipsoidal centre , so the plasmas is very centralize , so we can enlarge the area of disposition 椭球谐振腔因其结构的特点,可以满足大功率的需求,并且耦合微波从椭球的一个球心发出,在椭球的另一个球心产生等离子体,等离子体比较集中,而且沉积速度快,适合大面积的沉积。
Now the 2d precision of spatial points is very great , but because by usual correlation fitting method we can transfer gps ellipsoidal height into normal height of the local geoid is considered as mathematical curve plane , it is not conform the fact of mountainous districts so the precision of elevation is so small that it is not satisfied with the requirement of leveling 目前，地面点的平面位置确定精度已相当高，但高程精度始终未能达到水准测量的要求，因为将gps大地高转化为水准正常高的拟合推估方法是将局部大地水准面视为数学曲面，常常与实际情况差异较大(特别在西部山区差异更大) 。
This network ’ s structure is similar to the rbf neural network rather than the conventional ellipsoidal unit neural network . in the new network , the ellipsoidal unit functions are used in the hidden layer , and the weights between the hidden nods and the output nods are all connected . a method of rough k - means is used for obtaining the centers of ellipsoidal basic functions and the way of deciding the threshold 本文改进了一种椭球单元神经网络,它与经典椭球网络的结构不同,而与rbf神经网络结构类似:它的隐层节点采用椭球单元函数,代替了rbf网络的高斯基函数,并且用粗糙k -均值方法求取椭球基函数的中心,给出了确定初始阈值的方法。
3 . the solution for the distribution of potential internal the dielectric ellipsoid has been obtained by means of ellipsoidal coordinates , and has obtainted the expression of the polarization field strength in the dielectric ellipsoid , calculated the included angle value of polarization vector and the external field vector , making programe to compute to get the relation shetch between the included angle value of polarization vector and the external field vector and we have discussed the result and hold that the direction of polarization field strength with that of the external field don ’ t always strict antiparallel 二、讨论了带电粒子在均匀电磁场中的相对论运动规律。三、讨论了在均匀电场中电介质椭球体的极化规律。证明了电介质椭球内的极化场强方向与外电场方向并非严格相反,只有当外电场与电介质椭球的某一主轴平行或者当椭球体三半轴的大小都相等时,极化场强方向与外电场方向才严格相反。
