反点

I recommend Canon EOS DSLR cameras for long-exposure astrophotography because of their proven performance, low noise and ease of use in working with true raw files.

我推荐佳能EOS数码单反用于长时间曝光的天文摄影，因为它们已被验证的表现，低噪声与真正RAW文件（注：这点是针对尼康的RAW做了手脚来说的）的易用性。

This will give you the proper contact point for the one-handed backhand.

这将给你的单手反拍适当的接触点。

These curves contain a shape parameter which can adjust the softness of curve and have the same continuity with the original B-spline. In succession, using the positive conditions of Bernstein polynomial to find a range in which the shape parameter takes its value so as to make the corresponding interpolating curves monotonicity-preserving and C~2 continuous.

利用奇异混合的思想构造出一类带有形状参数的多项式样条曲线，即均匀α-B样条曲线，在无需反求方程组、迭代过程和最值求解的情况下就能轻松做到插值给定的点列；它含有形状参数α，这就增加了曲线的柔性，同时又和原B样条曲线具有相同的参数连续性。

We divide this interval into several subintervals, based on deviation points, find the best uniform approximation polynomial of each subinterval, and then denormalize the computation result to the final result.

论文摘要：根据切比雪夫定理，提出了一种适于FPGA实现的函数逼近新方法：通过区间映射关系，将函数定义域映射到较小的逼近区间内，并按照交错点对逼近区间进行分段，分别求出每段的最佳一致逼近多项式，对函数进行分段逼近，最后将逼近结果反映射，得到最终的函数计算结果。

Owing to the anisotropic and the biharmonic nature of microwave radar backscatter on spaceborne scatterometer, and to the scatter model function nolinear and the existence of various noise sources in the measurements in addition to the model function, the

由于卫星散射计探视雷达回波的各向异性的双调和性质，同时由于散射物理模型函数的非线性及信号中存在噪声，使得常规点方式风场反演中风向有多至4个解的多解存在。

Owing to the anisotropic and the biharmonic nature of microwave radar backscatter on spaceborne scatterometer, moreover, scatter model function nonlinear and the existence of various noise sources in the measurements in addition to the model function, the retrieval wind results consist of as many as four wind directions.

摘 要 由于卫星散射计探视雷达回波的各向异性的双调和性质，同时由于散射物理模型函数的非线性及信号中存在噪声，使得常规点方式风场反演中风向有多至4个解的多解存在。

In this paper by using Suzuki-trotter thoughts,we map 1D quantum Heisenberg chain into an equivalent 2D classical system.

利用Suzuki－trotter思想，把1维海森堡链映射为2维经典系统，在trotter方向采用双链近似，算出反铁磁系统的每个格点的自由能，讨论其热力学性质

The research has been carried out basing on the conclusion that the image of connected set under the closed point-to-set map is a connected set.

本文通过反例说明了连通集上闭的点集映射的象集未必是连通集，从而揭示了多目标规划有效解集连通性研究中存在的问题。

The former applies to those situations that the formulas of two projections are simple and easy to find out the direct relation of the plane rectangular coordinate.

数值变换法应用范围较广，它可以避开较复杂的投影坐标公式的反解问题，求出两个不同投影平面场上点的对应关系。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
