最差的

In the operating interface of PC, there are some curve fitting of the measured data.

采用了一些数学方法进行了数据的取舍、插值的处理，并基于最小二乘法的原理对测量数据进行了多项式拟合和最小方差的拟合。

The proposed beamformer represents a modification of the popular minimum variance distortionless response beamformer. It minimizes the array output power while maintaining the distortionless response in the direction of the desired signal and a sidelobe level that is strictly guaranteed to be lower than some given threshold value.

它是通常的最小方差无畸变波束形成算法的改进形式，使阵列输出信号功率最小的同时，保持目标信号方向的无失真响应，并且严格保证旁瓣低于某一给定值，抑制干扰。

The integrate style fleuret players were most excellent than other styles' in speed, accuracy and stability of decision-making.

整合化风格的花剑运动员在决策速度、准确性和稳定性上最好，灵活性风格次之，层次化风格的决策速度最慢，决断性风格的决策稳定性最差。

For those students who made errors, the type 9 was found to be the most difficult case. Type 2's have shown good results in other concepts. And type 8 students have performed the poorest in the aspect of equivalence fraction, but did better in simple fraction concepts.

对犯每一错误类型的学童而言，类型九之错误类型最困难，犯错误类型二（不了解分数符号平分意义）的学童在其他概念的表现情形良好，另外八个错误类型的学童，在等值分数概念表现最差，简单分数概念表现最好。

Necessary and sufficient conditions for equalities between a 2 y′y and minimum norm quadratic unbiased estimator of variance under the general linear model, where a 2 is a known positive number, are derived.

给出了一般线性模型下方差的最小范数二次无偏估计相等的充要条件，并且当高斯马尔可夫估计与最小二乘估计相等时，获得了一个相对简单的条件，最后给出此条件应用于抽样调查的一个例子。

1On the basis of pattern recognition analysis and in the light of the spectrum oflight source and the spectral response of CCD sensor as well as the spectral reflectance ofkernels,it is found that for the monochromic image recognition system and under the con-dition of reducing the probability error of classification to minimum,the optimum lightsource is a monochromatic light,the wave length of which is that rendering the series re-sponse of the difference between the spectral reflectances of two classes of kernels and theCCD sensor spetral response maximum.

在模式识别理论分析基础上，依据光源光谱、CCD摄像元件光谱响应以及作物籽粒表面反射率光谱特性，在使分类错误概率最小的目标下，得出籽粒黑白图象识别系统最佳光源为单色光，其波长为使两类待识别籽粒反射率光谱差值与CCD光谱响应二者的串联响应最大的波长。

The mixture phase of anatase and rutile showed the highest photoactivity, and the photoactivity for rutile was most low, due to that more hydroxyl radicals were detected in the suspension of mixture phase of anatase and rutile.

混晶样品具有最高的光催化活性，金红石光催化活性最差，这主要是因为混晶样品在可见激发下所产生的羟基自由基最多，而金红石样品能够生成的羟基自由基最少。

As the density of breast tissue itself very poor, many small lesions showed calcification, the breast X-ray photography is the traditional diagnostic radiology in the most difficult examination of the machinery and technology of the most stringent requirements.

由于乳腺组织本身的密度差很小，很多病变表现为微小钙化，因此乳腺X线摄影是传统放射诊断中最困难的检查方法，对机器及技术的要求也最严格。

Agricultural Bank was the last of China's large banks to be recapitalised by the state in preparation for restructuring and an eventual IPO and it is generally viewed in China as the worst-performing and worst-managed of all banks.

在中国大型国有银行重组并最终上市的改革方案中，农行是最后一家调整资本结构的银行，在中国，它被普遍看作是所有银行中业绩最差、管理最糟糕的一家。

Firstly,an image was segmented respectively by the two-peaked histogram method,the Otsu method and the consistency criteria method. Then a criterion to value the image quality based on information entropy was made by rules,which was related to the image sizes of objects. The appropriate threshold value,by which image segmentation was implemented to judge the burden temperature distribution most efficiently,was obtained.

该方法首先利用双峰法、最大方差法和一致性准则法分别对图像进行区域分割，再根据图像目标大小，运用知识规则制定判断图像质量的信息熵评价准则，选择合适的分割阈值，获得对判断料面温度分布最有利的图像区域特征。
