訓練范圍非常廣泛，包括抗災、撲滅山火、清理油污、水災拯救、核幅射防護、心肺復甦法及一般搶救技巧等。There is presently a widespread need for room temperature gamma and x - ray imaging capability for both medical and industrial applications. the interest toward the use of cdznte detector was greatly increased in the recent years because they offer a good trade - off between key perfonnance, such as the energy resolution and the absorption efficiency. and the complexity of the experimental equipment
半導體探測器是上世紀六十年代以來得到迅速發展的一種新型核幅射探測器，其能量解析度高、線性響應好、脈沖上升時間短、結構簡單、探測效率高、操作方便，在核物理實驗和研究方面得到廣泛的應用。Therefore, the crucial factor of technology of nucleus - detection is nuclear spectrum data collecting system whose core is the multi - channel analyzer ( mca )
所以以多道脈沖幅度分析器為核心的核能譜數據採集系統，是核輻射探測技術的關鍵。X fluorescence can quickly carry out measurement without damage and motion. it was widely adopted in geology, mining, environmental - protection, archaeology and industrial - analysis. its principium is that in measurement of radioactivity, the pulse energy is directly proportional to pulse signal amplitude detected by the radiation detector
X熒光方法可以實現快速、原位、無損測量，被廣泛應用於地質、礦業、環保、考古、工業在線分析等領域，其原理是：在核能譜測量工作中探測器輸出的脈沖信號與入射粒子的能量成正比，通過測量脈沖信號幅度，得到入射粒子的能量。It can be concluded that the elevated ability of penaeus immune system is realized via increasing po production instead of increasing of unit enzyme activity of po. since the biggest number of hemocytes, semigranular cells and po production have been obtained after - 1, 3 - glucan and lps stimulation, it implies that the - 1, 3 - glucan and lps would be the most efficient immunostimulant on shrimp, penaeus chinensis, among the immunostimulants used
透射電鏡下的觀察結果表明，中國對蝦血細胞的超微結構在免疫刺激前後也發生了變化，三種血細胞的糙面內質網、核糖體和線粒體的數量均有一定程度的增加，其中以小顆粒細胞和大顆粒細胞的超微結構變化幅度最大。The steel plastic pipe has strong erosion resistance, longer service life, as well as prevent atomic radiation to raise the safety of plant
倍多原子能發電廠用鋼塑管輸送液體，不僅防腐能力強，使用壽命大幅度提高，而且可防核輻射，增加核電廠的安全其他諸如天然氣There are charge distribution of the nucleons a which is not a point, thus, in our invariant amplitude the form factor of nucleons a will come spontaneously, the cross section will be much imfluenced by the form factor
由於在反應中原子核a為有大小電荷分佈的粒子而不是點粒子，從而在計算不變振幅過程中會出現形狀因子，這會對所計算的散射截面有很大的影響。Using it, time amplitude converter and pulse neutron generator, the y spectra of 14mev pulse neutrons is measured. utilizing the time difference of several different reactions about the interaction of neutrons and nucleus, the whole spectra and the capture spectra are measured. a method that uses double gate subtracting background to gain the fast neutrons " inelastic scattering y spectra is introduced
研製了一種線性門電路，介紹了它與脈沖中子發生器、多道脈沖幅度分析器配合，進行14mev脈沖中子譜的測量，利用中子和原子核相互作用的幾種反應在時間上的差異，測量了總譜和俘獲譜，採用雙門減本底方法得到了快中子非彈性散射譜。In the lecture, dr lui will provide the latest knowledge of nearby space environment, examine the correlation between space disturbances and our daily lives, including the radiation dosage for frequent airplane travelers compared to that of workers handling nuclear fuel, explain sun activities such as sunspots, solar flare, solar wind and space storms, etc. and how they will damage space assets and satellites for communication and navigation systems that our mobile telephone network, television broadcasting and flight routes will also be affected
講座上呂博士將以深入淺出手法，介紹科學家對太空天氣的認知預報研究工作，以及黑子耀斑風暴地磁暴和極光等太陽活動，對我們日常生活的影響，如經常乘坐飛機旅客跟核電廠工人所受的幅射影響比較，以及太空天氣對地球的實質影響。分享友人
