We calculate the field distribution near focus of an aplanatic system for incident ASPBs with different polarization orders and initial azimuthal angles, and based on the simulation results, we find some unique focusing properties of the beams, such as ever on-axis energy null, strong longitudinal field, and flowerlike intensity distribution at focus.

The measuring device is structured by including a He-Ne laser; a beam expander, a soft aperture slot and a off-axis parabolic mirror to be measured are arranged in turn along the direction of the emergent laser beam direction of the He-Ne laser; a standard cross hair and a micro objective are arranged in turn on the direction of the reflected beam of the off-axis parabolic mirror; the micro objective is arranged on the focus of the off-axis parabolic mirror; the focus is imaged on an area array CCD; the output end of the area array CCD is connected with a computer; the off-axis parabolic mirror is fixed on a five-dimensional electric adjusting frame.

一种离轴抛物面镜点聚焦能力测定装置和测定方法,测定装置的构成包括:一台He-Ne激光器,沿该He-Ne激光出射激光束方向依次设置扩束器、软边光阑和待测的离轴抛物面镜,在该离轴抛物面镜的反射光束方向依次设置标准叉丝和显微物镜,该显微物镜位于所述的离轴抛物面镜的焦点,所述的焦点成像于面阵CCD上,该面阵CCD的输出端接计算机,所述的离轴抛物面镜固定在一五维电动调整架上。

The cause of the earth tide force is its elliptic orbit movement. There is the tide caused by the earth on the moon because the earth is the focus of the moon moving orbit, but there is not the tide caused by the moon on the earth because the moon is not the focus of the moving orbit of the seawater on the earth.

地球的潮汐力是由椭圆轨道运动产生的,由于月球的轨道运动是以地球为焦点,所以在月球上可以产生受地球影响的潮汐,而不可以产生相反的潮汐,因为海水或岩浆没有以月球为焦点的轨道运动。

Previous researches didn't discuss the effects of payment ways on consumers' purchase intentions. Therefore, the first issue to be discussed is what the difference of the intentions to purchase is between two payment ways. The following is to investigate the cross effects between regulatory focus、payment timing and payment ways. The experiment is 2 x 2 x 2 x 2 x 2 mix –factor experiment of design. Every subject was assigned one of the two regulatory focus manipulations and had to judge four payment methods which were composed of two within-subject variables — payment timing and payment ways. At the same time, different product durability and product types were considered.

而以往的研究并没有针对付费方式做探讨,因此对於在「分期付款」与「一次付清」下的消费者购买意愿差异所知甚少,故本研究第一个要探讨的问题就是这两种付费方式下的消费者购买意愿是否有差别;再来由於以前关於调节焦点与付费时间对於购买意愿的影响的研究大多只集中特定产品种类上,并无全面性的探讨,因此本研究针对这部分做更深入全面性的研究;最后探讨付费方式、调节焦点与付费时间三个变数的交叉效果对於消费者购买意愿之影响。

This invention relates to a slider (11) for an optical data writing/reading apparatus (1), the slider carrying an optical lens (40) defining a focal point (42), the slider having a configuration such that, upon variation of the disk speed such as, for example, caused by a slider movement from an inner diameter to an outer diameter, the pitch angle varies owing to a pivot movement about a pivot axis which lies in a vertical plane through the focal point, the pivot axis preferably coinciding with the focal point.

本发明涉及用于光学数据写/读装置(1)的滑动器(11),在该滑动器(11)上装有确定焦点(42)的光学透镜(40),该滑动器具有这样一种结构,以便于在诸如滑动器从内径到外径运动造成盘速变化时,由于围绕位于经过焦点的垂直平面内的旋转轴的枢轴运动而改变倾斜角。
