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。

As a new comprehensive information technology, Virtual Reality plays an unsubstituted role in many fields.

The theory and basic assumption of distributed hydrological for water resources assessment under various environment is introduced to solve the problems of restoration distortion and restoration invalidation in traditional method. A method, namely UCMV (upreach for calibration and mid-reach for validation), based on parameter calibration by up-stream runoff station and verification by validation midstream station is developed.

为解决变化环境条件下水资源评价中的&还原失真&和&还原失效&问题，本文提出基于物理参数的分布式水文模型用于变化环境下水资源评价方法的原理和假定，以及基于此原理利用上游测站流量进行模型参数率定和中游测站进行验证（简称UCMV， Up-reach for Calibration and Mid-reach for Validation）的水资源评价新方法。

Renal cell carcinoma is a common neoplasm in urologic system.The incidence rate is high and the prognosis is poor.

By torque split method and combination of a full-toroidal variator, an epicyclic gear train and a fix-ratio gear, the full-toroidal traction IVT is capable of changing the reduction gear ratio up to plus infinite or minus infinite.

摘要牵引式全环面无限变速器是采用转矩分流方法，把全环面可变耦合器与行星齿轮机构及定速比齿轮机构结合起来，其减速比可以达到正无穷和负无穷，即变速时输出轴可以由正转经零转到反转，因而命名为无限变速器(Infinitely Variable Transmission，简称IVT)。

Researchers discovered by taking fMRIs of participants' brains as they played that when the predator was a distance away, there was increased activity in areas of the brain responsible for the more sophisticated processing, such as the ventromedial prefrontal cortex, a section of the cortex (the brain's main computer) located just behind the eyebrows.

通过对游戏中的参与者的大脑的核磁共振，研究人员发现，当捕食者尚远时，大脑中负责精密程序的区域活动愈加频繁，如腹内侧前额皮质（以下简称 vmPFC ），位于眉毛后面的脑皮层。

Objective:Evaluating the method of trace median tissue culture ineffective dose(trace TCID50) in determining the virucidal effect on the four commonly used disinfectants to poliovirus.
