大角度
Examples
- On such a basisthe commonly used monomial error accumulating totals correction method is introduced . the author proposes a coordinate transformation method to deal with its drawbacks of maths model imperfection , not applicable to lange - angle deviation and adding to the difficulties of equipment . while orientating the order of matrices according to the principle of the accordance between coordinate ' s rotating order and the physical process of device measuring , a strict maths model of the influence of axis system deviation on surveying angles is concluded and the corresponding correction method is induced . its far - reaching meanings are as follow : ( 1 ) the maths model of the influence of axis system deviation on surveying angles established by the new method is concluded after considerations for the three deviations simultaneously . changes under all circumstances are included , so it is theoretically a perfection of maths method
在此基础上介绍了国内目前采用的轴系偏差对测量角影响的经典改正方法?单项差累计改正法，并针对该方法存在的数学模型不完善、对大角度偏差不适用、增加设备调整难度等缺陷，提出采用坐标变换方法，并根据坐标的旋转次序与设备测量的物理过程相符合的原理定位各矩阵的先后顺序，推导出了轴系偏差对测量角影响的严格数学模型，归纳建立了相应测量角的改正方法。 - Based on the theory of glow discharge , the angle distribution of electron and the recombination process are simulated by adopting monte carlo method . the doping process of n - type diamond film is investigated by this method for the first time . the results indicate : 1 ) the scattering angle of electrons near the substrate is mainly lange - angle , which is helpful to grow diamond film over a large area when glow discharge is kept ; 2 ) after considering the recombination process , the number of particles distribution is provided
主要结果如下： ( 1 )研究了电子在雪崩碰撞和分解电离后的角分布情况，结果表明基片附近电子的散射以大角散射为主，在维持辉光放电的条件下，较高的偏压和工作气压对金刚石的横向连续成膜是有益的； ( 2 )考虑了低温合成金刚石薄膜过程中电子与各种碎片粒子的复合过程，给出了不同的复合系数情况下的粒子数分布，结果显示各种碎片粒子的分布随复合系数的变化会出现粒子数分布的涨落现象。
