The main research work is shown as below : 1. summarize the focal property and aberration correcting ability of vls plane grating
主要研究內容： 1 、對平面變柵距光柵的聚焦特性和像差校正原理進行了較全面的綜述。 -
With the focal property and the aberration correcting ability, the varied line - space ( vls ) grating has been successfully used in the areas of astronomical physics, synchrotron radiation, fiber communications and so on. therefore, the ruling of the vls grating is one of the greatest significant tasks of the grating fabrication
變柵距光柵具有像差校正、自聚焦等優點，在天文物理學、同步輻射、光纖通信等領域有著重要的應用，因此，變柵距光柵的刻劃技術一直是國際光柵製作領域的重大課題之一。 -
Because the land property rights in agriculture large - scale management plays an important role as well as in agricultural development efficiency. it gradually becomes the focal point
農村耕地的產權制度作為影響耕地規模經營和農業發展效率的重要因素，正逐漸成為人們關注的焦點。 -
The second property concerns the brightness of a projected image, which depends on the focal length and facial, or surface, area of the imaging mirror
第二項考慮的特性是投影的明亮度，這要視焦距與鏡面（鏡子的表面）而定。 -
Numerical result illustrates that focal length becomes longer when incident wavelength becomes shorter, however the relationship between focal length and incident wavelength is n ' t absolute inverse ratio, it is that the increasing of focal length is faster than the decreasing of incident wavelength. at the same time the numerical result also show that scalar theory ca n ' t be used in the rigorous analysis of the dispersion property of subwavelength diffractive microlens
然後研究了亞波長衍射微透鏡的色散特性，表明亞波長衍射微透鏡的焦距隨著波長變短而增加，但是波長與焦距之間並非簡單的完全反比例關系，而是隨著波長的減小焦距增加得更快，同時指出標量理論已不能準確分析亞波長衍射微透鏡的色散特性。 -
From the fresnel diffraction equation, we calculated the intensity distribution of the fhb in free space, and found that there is an interested propagation property of the fhb before the focal plane. that is, with the increase of the propagation distance z, the dark spot size ( dss ) of the fhb is first increased, and then decreased, the dss has the maximum value at the position of z = - f / 2
發現在焦平面之前有一個非常有趣的傳播性質，即隨著傳播距離z的增加，這一聚焦中空光束的暗斑尺寸（ dss ）先從另變大然後再變小，最大的暗斑尺寸的位置在z = f / 2處。 -
The intellectual property department serves as the focal point for intellectual property policy, law and acquisition and public education on intellectual property protection. it provides expert policy advice to the commerce, industry and technology bureau and legal advice to other government departments on intellectual property. it comments on draft intellectual property bills
知識產權署是制定知識產權政策和法例、批予知識產權，以及推廣保護知識產權公民教育的主要部門，負責就知識產權向工商及科技局提供專業政策意見和向其他政府部門提供法律意見，並就各項知識產權條例草案擬稿給予意見。 -
Ncd that the premium is discounted without claim and the premium is punished with claim is one way of the insurance company which attracts the customer and strengthens the fairness, and also is one of the focal points that the theory circle and practice circle of the insurance. it is not only because ncd is the special system of the car insurance that accounts for about 60 percent of property insurance premium gains, but also the structure of car insurance premium under ncd is more excellent
對無賠款實行費率優待和對賠款實行費率懲罰的無賠款優待制度一直是保險公司吸引客戶和強化公平的手段之一，也一直是保險理論界和實務界研究的重點之一。這不僅是因為無賠款優待制度是占財產保險保費收入60 %左右的車險特有的制度，而且因為在無賠款優待制度下的車險費率結構是更優的。
