Example Sentences:

	1.	The feasibility and some advantages of employment of sil have been discussed . the numerical aperture are calculated when laser pulse is defocusing . in contrast with traditional microscopy objective , the employment of solid immersion lens can effectively increase the numerical aperture of the recording system ; thereby it can increase the volumetric density and decrease the demand of the incident laser power 当脉冲聚焦点相对于固体浸没透镜底面离焦时，对系统的有效数值孔径进行了计算，结果表明采用固体浸没透镜离焦的方式进行记录，系统的有效数值孔径最低可增大到固体浸没透镜插入前的折射率倍，其数值孔径的理论极限值为存储介质的折射率。
	2.	The performance of the pbg antenna using the new pbg cover together with a pbg substrate is studied by the fdtd method together with the pml boundary treatment . the numerical results show that a more focused beam radiated in the broadside direction is achieved . the gain of the pbg patch antenna in the forward direction is improved by about 6 db . the radiation directivity is improved significantly and reaches 11 . 5 db , which is 0 . 4 db less than the maximum value that is allowed physically for this size of the antenna ( this difference is about 4 . 1 db less than the difference achieved by thevenot et al . , 用fdtd方法并结合pml吸收边界条件，我们对加了这种新的覆层结构并且基底钻孔的复合结构电磁(光子)晶体贴片天线的性能进行了研究，结果证明加了这种新的电磁晶体覆层结构以后，天线的波束收拢很多，并且向前辐射的增益大大提高，与普通天线相比，天线的e面和h面方向图上向前辐射的增益均提高了约6db ，另外，该复合结构天线的方向性系数达到了11 . 5浙江大学博士学位论文db ，与该物理尺寸天线的方向性系数的理论极限值( 11 . 9db )相差0 . 4db ，该差值比thevenot等人设计的电磁晶体覆层天线的相应差值减少了约4 . 1db ，比qiu等人设计的电磁晶体天线的相应差值减少了约1
