查询词典 rotation

The specificity of the surface gained in this way is that when the beam of rays parallel to its axis of rotation falls on it, the beam is reflected so that all the rays meet in one point, known as the focus, in the same way that optical lenses focus light rays in their focus.

抛物线的表面或曰抛物面，是由抛物线围绕其对称轴旋转而成，其特点是，和抛物线对称轴平行的射线波束被抛物面所反射，所有的电波都在同一点汇聚， 1 September，2009 3D 角反射天线作馈源的 5.8GHz 偏馈抛物面天线我们把这点叫做焦点。

According to the characteristic that the definition point of the Q matrix of wave front is always located on the extremum point on the axis of the beam, a three-dimensional formula for the rectificative factor of phase in complex ray paraxial approximation is proposed, which calculates the rectificative factor of phase directly without considering the calculation of the main directions and curvatures and the rotation of the coordinates, thus simplifying the paraxial approximation calculation by the complex ray expansion method.

根据波前Q矩阵的定义点总位于波束轴上极值点的特点，提出了三维复射线近轴近似相位校正因子计算公式。该公式不用考虑主方向和主曲率的计算和坐标旋转，直接计算相位校正因子，从而简化了复射线展开法的近轴近似计算。

Next offseason looks worse. There were reports over the weekend that the Cubs were near a deal for Carlos Zambrano. If so, there will be no prime-aged, top-of-the-rotation stalwarts available in the next free-agent market. The following offseason such starters as Jon Garland, Jake Peavy, C.C.

这样的状况在2007年球季结束后只会更糟，据报导指出，小熊队和Carlos Zambrano的合约谈判可望在近期达成共识，如果真是如此的话，明年的自由球员市场将会没有任何年轻、名列球队头几号先发的投手投入市场，或许后年的自由球员市场上会出现Jon Garland、Jake Peavy、C.C。
