The Tyrolean Iceman witnessed the Neolithic-Copper Age transition in Central Europe more than 5,000 years ago. His mummified corpse was recovered from an Alpine glacier on the Austro-Italian border in 1991. In 2000, scientists defrosted the Iceman's body for the first time and sampled DNA from his intestines.

提洛尔冰人是五千多年前中欧地区从新石器时代到铜器时代转变的证据，在1991年，人们在奥地利和意大利的边界处即阿尔卑斯冰川处发现了这具干尸，2000年，科学家第一次解冻了这具干尸并从他的肠中提取了样本DNA。

Surface water was sampled at the three red tide stations during the Guinardia delicatula bloom in Jiaozhou Bay on February 9-10, 2004 and the colloidal substances were separated by filtration(0.7μm)and cross-flow ultrafiltration (1000 Daltons). The organic carbon in the filtrates and retentates were analyzed respectively. Heterosigma akashiwo and Skeletonema costatum were cultured in the 000Daltons ultrafiltrate and the retentates with different amount of colloidal substances (1000 Daltons-0.7μm).

2004年2月9~10日在胶州湾发生的柔弱几内亚藻赤潮期间分别在3个典型赤潮站位采集表层水样，利用过滤(0.7μm)和切向超滤(1000 Daltons)分离赤潮暴发水体中的胶体物质，分析了不同滤液及截留液的有机碳含量，并将赤潮异弯藻和中肋骨条藻在000 Daltons的超滤液及具有不同含量胶体物质(1000Daltons~0.7μm)的截留液中进行培养。

Overshoot and undershoot are sampled, not 100% tested

过冲和下冲的样本，而不是100％测试

With the objective of the robot′s steady movement, the trajectory is sampled equably and each segment is considered as uniformly variable motion. To guarantee tracking precision, the relation between the tracking control error and the output torque of the controller is analyzed from the point of engineering.

而按照通常的规划算法所规划出的"最优"参考轨迹在实际中却难以应用，因为这一参考轨迹是基于机器人的精确动力学模型得到的，没有考虑实际系统中存在的模型不确定性，也未考虑控制器的动态特性，因而跟踪精度得不到保证。

This paper expoles an algorithm about dearing surface defects detection by Support Vector Machines and principal component analysis that is the new branch of machine learning, in which the defective area and non-defective area are treated as two different textures and are sampled respectively to be learned, in order to reduce dimension, the image data can be processed by PCA.

提出了一种基于支持支持向量机和主成分分析的轴承表面缺陷检测算法，该算法把轴承中的非缺陷区域和缺陷区域分别看作两种不同的纹理模式，先利用主成分分析法对图像进行降维处理，然后用支持向量机方法对降维后的样本采样学习，然后进行分类判断。

A CW carrier signal, generated by Agilent Signal Generator, is transmitted to the subject, which reflects the modulated waves to the receiver antenna. The Agilent Spectrum Analyzer, with an under-conversion module inside, demodulates the received signal to 70MHz IF signal, which is then sampled by a ADC module in Agilent Vector Signal Analyzer. Digital quadrature demodulation is used to convert IF signal to baseband. We could finally get the respiration and heartbeat signal by further analyzing the baseband signal.

该系统由信号发射器产生载波，通过天线发射到被测物体；频谱分析仪内置的下变频模块将由物体反射回来的信号下变频到70MHz中频；中频信号经矢量信号分析仪采样，然后经过数字正交解调变频到基带信号；对基带信号进行滤波、FFT等进一步的数字信号处理后即可获得探测的心跳和呼吸信号。

All in all, after having analyzed the graph and the table, we may safely draw the conclusion that water is playing an increasingly important role in every aspect of our lives and that the water consumption gap between the two sampled countries indicates that the more developed a country is, the more water it will consume.
