查询词典 variance

The choiceness varieties of Canarium album were tested in three different places of Guangdong. The study researched the 3-4a trials after engrafting, the results were as follows:(1) The results of variance anaylsis indicated that there were highly significant differences in yield per plant and yield per crown projection area among clones, and the height, stem diameter and crown side were highly significant in some test sites. It showed that genetic diversity existed in yield per plant among clones, and selecting high yield clones were effective.

Comclusion: transpetrous presigmoid retrolabrinth approach was rational approach for surgery on petroclivus and -4- CPA; it抯 important for accomplish the surgery to study and master the anatomy and variance of this approach; there was relative anatomical relationship among those structure on posterior of petrous bone; AAMP was the extracranial mark of inflexion of TS and SS; LAM and PSC were obvious bone marks for operation; we can confirm the abraded range of petrous bone lean upon LAM and/or GSS beside abrading step by step as literature, and it抯 unnecessary and unrational to emphasize to show PSC if the surgical space was enough; preceding sigmoid sinus and high jugular bulb often appeared at right and would bring disadvantage effect; interspace ,between CN V and CNVII or CNVII and CNJXI, were available to reach clivus and manage the mass on the range.

经SS前迷路后入路是处理岩斜坡区、桥小脑角区病变理想的手术入路；研究和熟悉手术入路中的解剖结构及部分变异对指导手术十分必要；岩骨内测面的骨性结构之间有着相对稳定的空间关系；顶乳缝前角是SS和TS转接处在颅外的标志；IAM和PSC等结构可以作为手术中的重要骨性标志；以PSC确定岩骨的磨除范围是较安全和可靠的，但亦可以结合影像检查，以内耳道和乙状窦前缘为基点判定切除范围，如果操作空间足够，过分强调磨出半规管是不适当的；右侧GSS的宽度和深度较对侧大，SS前置和颈静脉球高位较对侧多见，这些都对右侧入路有不利的影响，但仍可以进行手术操作；三叉神经和面神经间隙及面l 神经和舌咽神经间隙方便到达斜坡并处理病变。l

The researches show that they are highly correlated, and we further discover from their shared variance why they are collinear.

该研究定量地发现这些拓扑指数之间是高度线性相关的，而且我们进一步从它们共享的方差分析中发现了它们为什么是高度相关的。

Exploratory factor analysis, confirmative factor analysis, and analysis of variance were used to analyze the datum, which was based on the investigation we carried out for three times in Bank A, and there were more than 700 people involved. Whats more, we tested the reliability and validity of the scale thoroughly, and we established a four-factor-model for Bank A in the background of Chinese culture.

基于前后三次在A银行共计700余人次的问卷调查，对采集的数据进行了探索性因素分析、验证性因素分析、方差分析等，并对研究结果的可靠性和有效性进行了全面的检验，建立了A银行员工岗位角色适应的四因素模型。

Which differs significantly from the current consortial licenses for electronic resources. Our simulation results of a numerical example demonstrate that the formation mechanism with proposed bidding and egalitarian sharing formulas can ensure the stability of a consortium. This, however, cannot be accomplished by using procedures prevailing in today's consortia. As for the cost allocation among member libraries, the egalitarian sharing formulas also offer lower variance in budgeting compared with other cost sharing methods.

数值模拟结果显示，此种基於竞标与合作赛局精神之结盟机制与成本分摊方式，能确保想要订购电子资源之图书馆都能在联盟之内，达成联盟之稳定性，这是目前图书馆联盟采行之作业方式无法达到的；另外，所采用之成本分摊计算方式较其他的方法所得到之预算结余的变异程度小，显示具有不错的公平效果。

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise. In order to extract cophasal axes more continuous and immune to noise, a novel approach is developed based on edge detection. Firstly, the median filter and improved Sobel method are used to preprocess seismic section images. Secondly, the threshold value is determined automatically based on variance to detect abnormal information. Finally, the complete cophasal axes are extracted after a post-processing.

由于边缘检测中常用的Sobel算子和Canny算子检测同相轴时对噪声免疫差，常因噪声因素引起边缘信息缺失导致同相轴提取不连续，本文采用中值滤波并对Sobel算子进行改进，对地震剖面图进行预处理，结合均方差自动确定阈值并进行异常检测，提取完整同相轴。
