变化点

This change may be showed on graph of level or altitude interval. The graph inflexion is the small structure's starting or ending.

这种变化可以从两条巷道中线水平间距或者曲线图反映出来，曲线图上的拐点即为小构造出现的位置或尖灭点。

Change of expression of AQP4 protein was the same like the change of expression of AQP4 mRNA. We observed it in model group was statisticsly higher than that of control group. The quantity of AQP4 protein in intervenor groups was remarkably lower than that in model group.But the quantity of AQP4 protein in intervenor groups obviously increased compared with control group.

5AQP4蛋白表达与AQP4 mRNA表达呈现相同变化趋势，与对照组相比较，模型组各时间点的AQP4蛋白的含量均显著升高，以造模后第24h最明显；AQP4干预组和HO-1干预组在各时间点的AQP4蛋白的含量均显著高于对照组，但明显低于模型组AQP4蛋白的含量。

Harris corner detection is a classical algorithm, but has not the property of scale invariant.

Harris角点检测是一种经典的角点检测算法，但不具有尺度变化特性。

Using traditional supervised and unsupervised classification approaches, combining wiping off isolated point and isolated area, I want to check out the changed areas.

吸收传统变化检测方法中的监督、非监督分类方法，结合分类后孤立点和孤立区域的去除，检测出有变化的区域。

Numerical solution of the model is maed by using Monte-Carlo sampling method.Its solution is astochastic field. It is showed by a real case that the model can describe the main trend and changing range ofpollutant'sconcentration at any calculating point,and the probability is added to the isopleth of the pollutant'sconcentration.

该随机模型的解是一个随机场，实例计算表明，它的解能够反映任一计算点的浓度变化趋势及范围，并能够给程度等值线附加上概率的意义，表现了在不确定因素的影响下，污染带随机变化的情况。

Using lag\|correlation analysis method, in terpretative variances analysis method,phrase comparing method to the wavelet an alysis result,we not only gained the variation at different scales of the globa l temperature and El Nino signals,the location of the jump points and latent sca le of these series,but also indicated the magnitude,extent of the effect of exte rnal forcing factors on ...

利用小波分析方法，辅之以滞后相关分析、解释方差分析及位相对应比较方法，得到了气温变化及ENSO活动在各尺度层次上的变化，突变点位置及特征尺度，并确定了太阳活动、火山活动和温室效应等外强迫因子对气温及ENSO的影响尺度、幅度及响应时间。

Based on weekly mean OISST, pentad averaged OLR and daily NCEP/NCAR reanalysis data, the intraseasonal variability of SST in the SCS is examined by using lag correlation analysis and composite analysis, respectively.

本文使用1982-1997年OISST周平均格点资料、OLR侯平均资料以及NCEP／NCAR再分析日平均资料集中的海表热通量、850 hPa风场以及海平面气压场等资料，采用不同的谱分析方法确认了南海全区SST季节内变化（30-90天）的存在性，并通过相关分析以及位相合成技术，分别研究了夏季风期间与冬季风期间南海SST季节内变化的基本特征和形成机制。

The magnitude of opened angle at a point pi in the contour can be easily calculated by the law of cosines, and its local extreme correspond to the sharper changes of the contour of the mode.

其轮廓上点p处的张角可用余弦定理很方便地求出，而张角的极值点则对应于轮廓急剧变化的地方。

Among them, the algorithm of Eigenface, the most widely-used method of linear map based on PCA, has become the mainstream criterion to test the performance of various FV systems.

目前，已经提出了许多特征提取的方法，其中基于主成分分析(PCA Principle Component Analysis)的Eigenface算法及其变形已经成为测试人脸识别系统性能的基准算法，该方法是模式识别判别分析中最常用的一种线性映射方法，是根据样本点在多维模式空间的位置分布，以样本点在空间中变化最大方向，即方差最大的方向，作为判别矢量来实现数据的特征提取与数据压缩的。

The coefficients between the sizeclasses and other quantification methods are found to vary with the particle size of the microfossil charcoal. The 202 touch pointcounts method is considered to be a better method for quantifying microfossil charcoal as it has high coefficients with other methods,smaller error and costs less counting time.

两种点接触法的微炭屑统计结果的相关系数高达0.93，反映了这两种方法所得微炭屑统计结果具有几乎相同的变化趋势。202刻点接触法由于与其他统计法的相关性都比较高，统计视域多且鉴定统计速度快，是进行微炭屑统计的最佳方法。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
