The Proto is an all-purpose tire that performs great on grass, dirt and even tarmac, the HB Block tires have been specially designed to work at their best in a variety of off-road racing conditions, including dirt, grass and astroturf, while the HB Khaos tires have been designed specifically to suit a range of off-road racing conditions, and are perfect for loose dirt, grass, and damp tracks.

原是一种多用途的轮胎执行伟大的草地上，泥土，甚至停机坪，乙肝块的轮胎经过特殊设计，工作处于最佳状态的各种越野赛事的条件，包括泥土，青草和astroturf虽然在哈尔滨Khaos轮胎已专门设计，以适应各种越野赛车条件，是完善的松散泥土，草，潮湿的轨道。

Though comparing Canny operator and center B spline dyadic wavelet, the following conclusion is proven in this dissertation: a Center B spline function has tight support and Canny operator hasn't. b Center B spline function asymptotic convergence to Gaussian function and the derivative of Center B spline function asymptotic convergence to Canny operator. c The derivative of fourth order center spline B function is more suitable as a optimal edge detector than Canny operator. d Center B spline function can balance the smoothing and approximation of original data, and the fourth center B spline function is the only optimal solution of two order smoothing problem. e The error between the valve of time-frequency uncertainty of the fourth center B spline function and the lower bound of time-frequency uncertainty does not exceed 0.143% of the lower bound. f The derivative of center spline B function can construct a stability dyadic wavelet and can give a fast algorithm for multiscale edge detection, but Canny operator can do neither.

作者给出了Canny算子与中心B样条二进小波严格的比较证明，得出如下结论：a中心B样条函数具有紧支集，Canny算子不具有紧支集。b中心B样条函数的极限收敛于高斯函数，中心B样条函数的导数收敛于Canny算子。c四阶中心B样条函数的导数比Canny算子更接近最佳边缘检测滤波器。d中心B样条函数比高斯函数更能兼顾对原函数平滑和逼近的折中要求，并且四阶中心B样条函数是二阶逼近问题的唯一最优解。e四阶中心B样条函数的时频测不准关系值与时频测不准关系下界的逼近误差不超过0.143％。f中心B样条函数的导数可以构成稳定的二进小波，存在快速的多尺度算法；而Canny算子不构成稳定的二进小波，无法给出快速的多尺度算法。

The clutter is assumed to be of Weibull distribution or characterized by a log-normal distribution. It is presented that a detailed derivation of the formula about asymptotic relative efficiencies of generalized sign test and Mann-Whitney detector are compared with optimum linear parametric detector.

选择韦伯分布和对数正态分布为两种非瑞利杂波模型，推导广义符号和Mann-Whitney检测器相对于最佳线性参量检测器的渐近相对效率的计算公式。

In this paper, we research the imaging problems beneath volcanic area. We sort common asymptotic conversion point gathers and perform velocity analysis to establish the initial velocity which will be used in PSTM. By scanning migration velocity and V p/ V s, we get the optimum migration velocity and

本文针对火山岩地震屏蔽层的转换波成像问题，通过对转换波共近似转换点道集进行速度分析，建立了转换波叠前时间偏移的初始速度场，通过速度扫描和纵、横波速度比值扫描确定最佳的偏移速度场和纵、横波速度比值，实现了在火山岩高速层覆盖区域的转换波偏移成像。

Delegates are the best practices to design async architectures because most of the things are internally handled by the CLR, and we do not have to bother much about them.

代表团成员还包括最佳做法，以设计，因为大部分的东西都是由CLR内部处理的异步架构，我们不必理会他们了。

Technology called asynchronous transfer mode, or A.T.M., which is thefoundation of many modern networks. But another company, Ascend

的通信技术开发出了最佳的芯片，但是另外一家公司，Ascend通信公司使用朗讯的芯片
