According to the variation , features of the integrand , the values of peaks and troughs are taken out and formed a slowly convergent series , and the repeated averaging scheme is performed to calculate the limit rapidly and accurately 根据被积函数的变化特点，将波峰和波谷值抽取出来组成慢收敛序列，利用重复平均法快速而准确地求出其极限值。
Depreciation on the fixed assets shall be accounted on the basis of the original cost , estimated residual value , estimated useful life and working capacity , according to the straight line method or the working capacity ( or output ) method 固定资产折旧应当根据固定资产原值、预计净残值、预计使用年限或预计工作量，采用年限平均法或者工作量（或产量）法计算。
According to different methods of feather extraction , distance average and swatch average are used respectively in the process of distance estimation , which furthermore reflect the whole information of lots of swatch belonging to the same type 针对同一类的多个样本，根据不同的特征提取方法，分别采用了距离平均法和样本平均法，进一步反映了样本的整体信息。
It is often the case in foundation engineering that foundation subsoils are consisted of more than one layer . up to now , hansen ' s method and meyerof ' s method for two - layered subsoils are the only two options for estimating the bearing capacity 这类非均质介质基础的极限承载力计算目前常用的是汉森加权平均法和迈耶霍夫的双层地基承载力计算公式这两种方法。
In this paper , the density of randomly chosen glass micro - beads with high retro - refractive index is determined using a weighting method based on static mechanics , and the measurement deviations are analyzed and discussed 摘要随机抽取有代表性的玻璃微珠产品，根据静力学称衡法原理，通过测量多珠统计平均法测量回归反射高折射率玻璃微珠的密度，并分析和讨论了测量误差。
Based on the weighted average method adopted in the first part , and by using numerical simulation and monte carlo simulation , we further present a study of the dynamics of id and q states potts model under an oscillating external field 基于第一部分采用的加权平均法，结合数值模拟和montecarlo模拟，我们进一步给出了一维q态的potts系统在谐振子外场中的单自旋跃迁动力学研究。
At the same time , we studied the distribution patterns of the young , middle - aged and old individuals respectively in the three populations as well as in other several concomitant species in the communities in which e . chloranthoides lives 三个种群的世代长度约为6一7a ，世代交替的时间较短。 4 、移动平均法对三个种群未来数量的增长趋势预测的结果表明，在未来2a 、 5a内，绪乞
