This article mainly carries on reconsidering to the uniform circular motion teaching experience,proposed the uniform circular motion teaching first step is enables the student to grasp the uniform circular motion accurately the basic concept,and proposes the solution centripetal acceleration and the centripetal force concept teaching method specifically.

湖北省 鄂州 2 。湖北武汉摘要：本文主要对匀速圆周运动的教学经验进行反思，提出匀速圆周运动的教学的第一步是让学生准确掌握匀速圆周运动的基本概念，并具体提出解决向心加速度和向心力概念的教学的方法。

Phase velocity error caused by position error of microtremor observation array is computed under different conditions such as two different dispersive phase velocity models of Rayleigh wave, three kinds of radius, 19 kinds of observation position mode and 6 types of position error.

为研究地脉动观测台阵中观测点之间的定位误差带来的影响，计算了在两种瑞利波频散模型、3种不同的圆周半径以及19种观测位置等多种情况下由6种定位误差引起的瑞利波相速度相对误差，结果表明：由于圆周上观测点数目有限，在不存在定位误差时，相速度误差也是存在的，随观测点位置的不同，相速度相对误差存在差异，其最大值约为最小值的3倍。

The magnet size （here the angle of the magnetic pole was used） modification to eliminate the phase shift was estimated by using a hard-edge approximation to the magnetic field distribution along a circle.

给出了由滑相角度估算磁极张角修正量的方法，根据滑相角度计算磁场沿圆周的平均值与等时性场的偏差；为消除此偏差，将磁场沿圆周的分布做硬边界近似，估算出磁极几何尺寸的修正量。

As we know, many results on analytic solutions of iterative equations are obtained by constructing a majorant series. For technical reasons, in previous works an indeterminate constant α, as the eigenvalue of the linearization of unknown function at its fixed point, is required to be off the unit circle or lie on the circle with the Diophantine condition.

已有的许多关于迭代方程的解析解结果都是运用优级数法得到的，并要求一个作为未知函数在其不动点处的线性部分的特征值的常数α不在单位圆周上或者α在单位圆周上但满足Diophantine条件。
