So the two methods have been chosen to detect and estimate the center of a tropical cyclone over China offshore.They are the Geometric Axisymmetric Center Positioning Method and the Velocity Distance Azimuth Display Positioning Method,respectively.The former decides the position of a tropical cyclone center using directly the Doppler radar radial velocity field,the latter does the position using the productV_(r×D of the Doppler radar radial velocity valueV_(r and the distance from observation site to radar center.

两种客观方法分别为几何轴对称中心定位法和速度距离方位显示中心定位法，前者直接应用多普勒径向速度场进行定位估计，后者则应用观测的多普勒径向速度场与观测点至雷达中心距离的乘积来估计台风中心位置。

Actually, calling them bar codes is a bit old-fashioned, because they store information in a two-dimensional (2-D) matrix of tiny squares, dots or other geometric patterns, rather than a stripe of black-and-white lines of varying thickness.

实际上，把它们称作条形码并不准确，因为它是用一个由小方块，小圆点或其它几何图形组成的二维阵列来表达信息，而不是用黑白相间的宽度不等的竖条纹了。

However, due to the irregular motion of the radar platform and the circular-scanning antenna beam, the inevitable geometric distortion on the focused images is necessary to be corrected.

The position of said examine bed on scanning plane and its sag from its nominal position can be found out according to the tangent channel of X ray along the outside near bed back and the geometric structure of X-ray emitting and detecting unit.

在通过X射线照射和探测装置扫描安置在检查床上的受检者的X射线CT设备中，根据沿切线方向向检查床背侧附近外侧前进的X射线被探测的通道位置和X射线照射和探测装置的几何结构，找到检查床在扫描平面中的位置。

To match the boundary conditions, the modified Bessel functions are expanded to the planar wave in the interface. Then the eigenvalue equations of different polarizations are obtained by scalar approximation. At last, the relations between propagation losses and the states of polarizations, the geometric structures of the fiber, the refractive index and thickness of the polymer are calculated.

论文首先给出其等效折射率数学模型，在纤芯和包层中，光场用贝塞尔函数及虚宗量贝塞尔函数的求和表示，在聚合物和金属中用指数函数的求和表示，交界面上采用将虚宗量贝塞尔函数用平面波展开的方法匹配边界条件，然后利用标量近似求出极化D型光纤不同偏振态光场模式的本征值方程，最后通过数值计算得到光纤的传输损耗与抛磨平面和纤芯之间的距离，聚合物粘接材料的折射率和厚度，以及偏振态之间的关系。

Dynamic pressure averaging pipe was generally applied to blowing rate measurement in rectangular pipe of power plant, the average velocity of flow in the section was represented by the average dynamic pressure at the line through the geometric center of the cross section, and then the blowing rate was determined.

针对这一问题，本文设计了基于&对数契比雪夫法&的送风流量测量装置，将5支动压平均管置于同一截面，按&对数契比雪夫法&选点位置开孔，把这5支动压平均管的静压输出孔、总压输出孔分别连接到一起作为传感器组件的差压输出，实验表明这种方法使测量准确度明显提高。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
