另外,還利用該劑量體系對12mev電子束輻照場的分佈及深度劑量分佈進行了實際測量,得到了與cta和fwt60等薄膜劑量計相一致的結果,這也進一步說明該劑量體系在電子束輻照上的適用性和實用性。Standard lamp and diffusers are very important calibration elements, in chapter three, first uv and vuv radiometric standard for calibration are introduced. then the fabrication and characteristics of baso4 diffuser and alminium diffuser are researched, the baso4 diffuser ' s hemispheric reflectance and bi - directional reflectance distribution function were measured and compared with lambtian surface, and the deviation from that of lambtian surface is given. in the experiment, al diffuser ' s brdf is researched, obtain the change of spectral characteristic of al diffuser, compare al diffuser ' s brdf before and after coated with al + mgf2, and different al diffusers with different surface roughness
鋁漫反射板作為一個漫反射光學元件安裝在太陽紫外光譜監視器的入射狹縫前,太陽紫外光譜監視器在軌測量時,太陽輻射入射到鋁漫反射板后進入入射狹縫,光譜輻照度的角度是變化的,本章測量了鋁漫反射的相對雙向反射分佈函數,研究了鍍膜( al + mgf _ 2 )前後光譜反射率的變化,漫反射的光譜特性及漫反射板表面粗糙度對相對雙向反射分佈函數的影響,使得測量數據反演成為可能。Sixteen sup - processed from 110k to 300k were found. the range of trap energy is from 0. 19ev to 0. 34ev. the maximum of the initial density distribution of the carrier in the traps locates 0. 23ev, and the curve deviated from guass type
本文採用一種tl曲線的自動分解技術,對硅橡膠輻照老化tl曲線進行了自動分峰,結果發現在110k ~ 300k的溫度范圍內有16個子過程,其陷阱活化能變化范圍為0 . 19 ~ 0 . 34ev ,被陷阱俘獲載流子初始濃度的分佈在0 . 23ev處具有極大值,且呈偏離高斯型的分佈。Thus the cumulative consequence of galactic chemical evolution starting from low metallicity agb stars, namely, the average abundance patterns of sbh part with 140a204 ( or the snl component part with 92a132 ) in different metal conditions, should be similar ( ornearly similar ) to the corresponding solar s - bajn component
低金屬豐度條件下,由於中子輻照量隨金屬豐度的降低而升高, s _ ( ml )產量低於s _ ( mh ) 。雖然s _ ( ml )分佈與太陽系有差異,但對于質量范圍92 a 132 ,任何金屬豐度下分佈與太陽系大體相似。Measurement of the fragment lengths was accomplished with the use of scion image analyzed software, which allows a curved fragment to be measured in a stepwise manner at nanometer level resolution, and the change laws of three forms of dna, supercoil, open circular and linear form as the dose increased were obtained
藉助于afm ,對粒子和兩種重離子誘發的dna損傷進行了納米水平的結構分析,並結合scionimage圖像分析軟體的分段測量方法,對輻照誘發的dna碎片長度分佈進行了納米級分辨的測量。There are many difficulties in target calculate curse, such as choosing physical parameter of target material, how to input the corresponding parameter and choosing coolant parameter etc. in the next studying, we need further consider power ' s distributing function with target structure and target material parameter diversification for irradiate damage
在靶件的計算中有如下難點:靶件材料物理參數的確定、程序中相應參數的輸入、冷卻劑的選取以及物理參數的選取。在後續工作中,我們還需進一步考慮中子產生靶區的功率分佈函數,輻照損傷對靶材熱工參數的影響程度等等。All the formulae get by spss was significantly different from p - test ( p < 0. 05 ). the measured illuminations show not only they agree with calculations but also their distributions are all uniformity. the formulae get by spss is reliable
經檢驗這三種光源在被照射面上的輻射照度都呈勻稱分佈,對測試所得數據,使用統計分析軟體spss擬合得出三種光源的輻射照度經驗計算公式,它們顯著性檢驗的p值都小於0 . 05 。分享友人
