Generally, the gravity introduced deformation of an optical lens with smaller aperture ( < ( 100mm ) within visible band is about ( / 20 even less than this value. for general optical lens, this error level can be entirely neglected. but for the high - accuracy optical system within extreme ultraviolet band, the error caused by gravity deformation will lead to imaging quality degradation
本文較為系統地介紹了光學鏡頭的裝配與調校方法，一般地講，在可見波段內，光學鏡片口徑較小（ < 100mm ）時，重力引起的變形一般/ 20左右甚至更小，對於一般的光學鏡頭這樣量級的誤差完全可以忽略，但在極紫外短波長的高精度光學系統中重力變形帶來的誤差會使光學系統成像質量下降。 -
Finally, i want to say an innermost thoughts and feelings, everybody specialist, and being living in my aperture, you are information embodiments, and you have also expend the accomplishment that the hardships were hard acquireed the today hence you are i am a tutor model that i studyed, and originating the in pinching poverty county of three gorges storehouse district, it is very much valuable as far as me present ( to pursue advanced studies ) the study opportunity, sincerely wising that you be able to be to my opportunity present, i surely be able to particularly value and thank you
請翻譯以下一段漢語最後，我想說一句心裏話，各位專家，在我眼中，你們是知識的化身，你們也付出過艱辛努力才取得今天的成就.因此你們是我學習的榜樣.我是一名教師，來自三峽庫區貧困縣，這次（深造）學習機會對我而言非常珍貴，真誠希望你們能給我這次機會，我一定會特別珍惜.謝謝 -
According to m. sheik - bahae ' s theory the sample has a negative nonlinear refractive index under 1064 nm pulse laser. it was determined as 6. 5 x 10 - 21 m2 / w. meanwhile, the minimum value of normalized transmittance of z - scan curves without aperture are found at the focus, and indicate that nickel one - nuclear complexes have nonlinear absorption properties
同時開孔z掃描曲線在焦點處出現透過率的最小值，表明它具有非線性吸收特性，其非線性折射率為6 . 5 、 10一， ， mz / w ;我們還利用歸一化透過率曲線算得了這兩種鎳單核配合物的三階非線性極化率的實部。 -
