The concept of the midpoint quasi - convex function is introduced , and some conditions are obtained to ensure that midpoint quasi - convex function is quasi - convex in the measurable function space 摘要本文提出了中点拟凸函数的概念，在可测函数空间中，给出了中点拟凸函数拟凸的若干个充分条件。
It is a 34 - bar simple moving average of the bar ” s midpoints ( h + l ) / 2 subtracted from a 5 - bar simple moveing average of the midpoints ( h + l ) / 2 , plotted in a histogram form 它是以5个价格之条形图之中点价(最高+最低) / 2取移动平均，再减去34支条形图之中点价(最高+最低) / 2之移动平均，并以柱状图之形式表示。
? the mean scores in every dimensions are all above 3 points ( midpoint ) , which indicates a general attitude of citizen ' s moral view of middle school students ( 2 )中学生公民道德观各维度的平均分均在3分(中点)以上，这说明中学生公民道德观从总体来讲是积极的。 ( 3 )中学生公民道德观存在一定的学校差异。
It is the lakers ' longest trip since 1960 - 61 , their first season in los angeles , but that 10 - game trip was broken up near its midpoint when the team returned home for several days before christmas 湖人队将暂时离开主场，其实是很长一段时间，他们将在15天中打9场比赛， 8713英里的客场的旅途将穿过超过半个东部。
Through master s merciful blessing and arrangement , we finally found an old house . after being remodeled by our fellow practitioners , the house has become a serene and beautiful spiritual center . it is located at the midpoint of the south - to - north subway 在师父慈爱的加持与安排下，同修们终于找到了一所旧房子，经合力重建后，现今已成为一处庄严美丽的灵修圣地。
On the basis of summarizing current fractal dimension algorithms , the random midpoint replacement algorithm was employed to obtain interpolating point according to the fractal features of remote sensing image , so the current widely used triangular prism method was improved 摘要在总结现有分形维数计算方法的基础上，根据遥感影像的分形特性，利用随机中点替代法获取插值点，从而对目前普遍使用的三棱柱面法进行了改进。
The other are a hybrid preconditioning strategy , in which a simple pivoting preconditioner is used in combination with the standard inverse - midpoint method and a new scheme for selecting the real point in formulating interval newton equation 使用混合预处理和优化实数向量：所谓混合预处理，就是联合了标准中点逆矩阵预处理和中枢预处理。优化实数向量就是选择合适的实数向量来缩小线性区间等式的解向量n ( x )所包括的范围。
This paper analyses deterioration model of bar code signals after the point spread function convolution , and presents two kinds of recognition algorithm in correspondence to different bluring degrees of bar code signal : one based on midpoints detection and the other based on waveform analysis 分析了条码信号经过点扩展函数卷积后的降质模型。针对条码信号模糊程度的不同，提出两种识别方法：基于中点检测的条码识别方法和基于波形分析的条码识别方法。
For processing of 3d and 3c seismic data , the reflected p - waves can be processed with the conventional methods , while the reflected converted waves can not be processed with the conventional p - wave processing methods , because their travel paths are asymmetrical , their common midpoint gathers are no longer common reflection point gathers , and their time - distance equation is non hyperbolic 在三维三分量地震勘探资料处理中，对于反射纵波资料可以采用常规方法进行处理；而对于反射转换波资料，由于其传播路径的非对称性，转换波共中心道集不再是共反射点道集，转换波时距方程也不是双曲方程，因此不能采用常规纵波处理方法来处理转换波资料。
Thirdly , to improve traditional method ( midpoint displacement algorithm ) , various coefficient scales are used in interpolating data . to the end of this paper , a series of experiments on interpolating data are conducted , which indicate that the interpolation improves the precision of results and avoids the creasing problem effectively 利用已有的dem数据进行几种不同方法的内插计算，计算结果表明改进的随机中点移位内插法能有效地避免插值点附近明显的“尖峰现象” ，且插值精度有了一定的提高。
