gamma line 中文意思是什麼
gamma line
解釋
譜線-
The object of single photon emission computed tomography ( spect ) is to reconstruct an unknown radioactivity distribution inside the body from projection data consisting of the number of photon collected on a collimated gamma camera. these projections are not simple line integrals but have point - spreads due to the imperfect collimator of the detector and attenuation due to the compton scattering. so
這種投影數據與透射ct中的數據不同，由於存在著光子的點擴散（由準直器引起）和衰減（由散射引起） ，已經不能用簡單的線積分來描述這個問題，因此相對于透射ct而言，這個領域將面臨很多困難。 -
After considering practical conditions of deposit, we applied gamma spectrometry ( gs ) methods to the whole deposit area and shallow seismic exploration ( sse ) methods to the west of no. 63 prospecting line of vii ore - body
在此基礎上，結合礦山實際情況，在整個礦區進行了伽瑪能譜的測量，並著重在號礦體63勘探線以西開展淺層地震勘探的應用研究。 -
In the foreign country, neutron induced prompt gamma - ray analysis ? ipga was used to analyze the elements in substance and has been used in real production and industry " s analysis on line now. in our country, the method has been studied and used from 70 " s and has been more and more perfect. however, the neutron source they used is the isotope source
在國外，早已開始採用中子感生瞬發射線分析法（ nipga ）對物質進行元素分析，如今這種方法已經應用於實際生產和工業在線分析，國內在八十年代也開始研究、應用這種方法，如今已日趨完善，然而，他們使用的中子源絕大多數仍然是同位素中子源，做為一種可行性實驗方法研究，我們採用脈沖中子發生器做為中子源，自行研製的線性門電路和多道脈沖幅度分析器相配合，獲取非彈性散射和俘獲譜，對物質進行元素分析。 -
