样本点

Methods Using conventional X ray equipments, with distance ranging from 40cm to 320cm,we selected seven distance exposure points and made sensitometry for two types of screen film system patterns(Okamoto DMS/Fuji new RX and Fuji HR Regular/Fuji HR N) and plot characteristic curves, gradient density curves and acquired characteristic values.

方法利用常规X线机在焦点胶片距离40～320cm的范围内，取7个距离曝光点，对OkamotoDMS／FujinewRX及FujiHRRegular／FujiHRN两种屏片体系样本做感光测定，绘制特性曲线、斜率密度曲线，求取特性值。

The L. hexandra samples, sullage and water samples collected from 6 sampling spots were brought into laboratory for analyses.

However, they have a weak correlation from the sample data results, so this paper made some innovations on the traditional model, and made comparison with the sampling point land price average method.

但从研究区的样本数据计算结果来看，两者之间呈弱相关，所以对传统的模型法进行创新，并与样点地价平均法进行对比验证。

In the 1990s, a more complete theoretical system - the achievement of statistical learning theory and neural networks, and other than because of the emerging machine learning methods of the difficulties encountered some important, such as how to determine the issue of network structure, overfitting and underfitting, the local minimum points ect, makes the rapid development and improvement of SVM in resolving the small sample, non-linear and high-dimensional pattern recognition problems in the performance of many unique advantages and can function to promote the use of fitted function and other machines learning problems.

上世纪90年代，一个较完善的理论体系--统计学习理论( Statistical Learning Theory，简称SLT)的实现和由于神经网络等较新兴的机器学习方法的研究遇到一些重要的困难，比如如何确定网络结构的问题、过学习与欠学习问题、局部极小点问题等，使得SVM迅速发展和完善，在解决小样本、非线性及高维模式识别问题中表现出许多特有的优势，并能够推广应用到函数拟合等其他机器学习问题中。

The standard curve was constructed by using gene chip after the methylated and unmethylated DNA were mixed at different ratio. Then treated samples of U266 cells were dotted on gene chip, obtained results were compared with standard curve to get the quantitative results.

采用基因芯片的方法，将完全未甲基化的DNA和完全甲基化的DNA混合后制成标准曲线，将U266细胞株样本处理后点在芯片上与标准曲线进行比较后得出定量检测的结果。

A satisfied cytologic smear, improvement of the smear preparation, understanding the particularity of the disease and cytologists's skill in diagnosis are critical to decrease the false-negative rate. It's important that gynecologis do multiple biopsy under vaginoscope to the patients who are suspicious of cancer but negative cytology.

获取满意的宫颈细胞样本、改进标本处理、认识到病灶的特殊性以及加强细胞学医师的学习和提高自身诊断水平是降低TCT假阴性的有效方法，临床医师对症状体征可疑但细胞学阴性的病例采取阴道镜下多点活检可减少假阴性的发生。

Based on the gravity center of the data points, the binned kernel density estimators described the key information of the original whole sample set and avoided the repetition computation in the evaluation phase.

分箱核密度估计算法利用基于网格数据重心的分箱规则，很好地提取了训练图像序列的关键信息，避免了采用全样本数据点的重复计算，大大提高了运动目标检测算法的实时性。

It has become a bottleneck to use Support Vector Machine due to such problems as slow learning speed, large buffer memory requirement, low generalization performance and so on, which are caused by large-scale training sample set and outlier data immixed in the other class.

支持向量机在许多实际应用中由于训练样本集规模较大且具有类内混杂孤立点数据，引发了学习速度慢、存储需求量大、泛化能力降低等问题，成为直接使用该技术的瓶颈。
