  1. The results show that there are really obvious scintillation in gcrs intensity at the periods of 10 - 60 minutes as expected by many scientists, such as dorman, et al. then we analyzed the data observed at beijing snm between two solar cycles " transitional phases by using wavelet method

    我們還計算了幾個磁暴前銀河宇宙線強度的短周期的變化特徵，計算結果顯示，磁暴前銀河宇宙線強度在10 ? 60分鐘范圍內出現明顯的閃爍，這是磁暴前銀河宇宙線強度變化的的一種先兆特徵。
  2. In addition, the study shows that the cmes " traveling direction is also an important factor, which influence the intensity of the geomagnetic storms. we also analyzed gcrs data from beijing super - neutron - monitor ( snm ) by using fft and power spectrum method

    我們對cme運動方向與磁暴強弱的關系進行了初步的研究，研究表明，同樣條件下，正對磁層頂的cme形成的磁暴更強，即cme的運動方向是影響磁暴強弱的一個重要因素。
  3. Nondestructive assay ( nda ) techniques have become powerful tools for quantitative determination of special nuclear materials ( snm ), and played an important role in nuclear material control and accounting ( mc & a ), also in inspection of nuclear safeguards

    無損分析（ nda ： nondestructiveassay ）技術已經成為定量分析特種核材料（ snm ： specialnuclearmaterials ）的重要工具，它在核材料控制與衡算（ mc & a ）方面以及在核保障核查工作中起著重要作用。
  4. Standard guide to procedures for calibrating automatic pedestrian snm monitors1

    行人區自動snm控制器的校正程序標準指南
  5. Standard guide to in - plant performance evaluation of hand - held snm monitors

    手持snm監視器內部性能評定標準指南

  8. Therefore it should be planned carefully. the properties of snm ( nuclide mass, isotopic composition, distribution, matrix, etc. ) are significant to nda instrument response, these physical properties must be well known throughout the preparation procedure

    因此，制備nda核標準樣品必須非常仔細的計劃，特種核材料的特性（核素的質量、成分、分佈和基體）需要確切地知道。
  9. In sections, we reduced the linewidth of parametric light considerably by use of the elements such as prisms and gratings or by etalons. we can obtain the linewidth less 2nm, less o. snm, less 0. 06nm, respectively

    第三章根據clbo - opo輸出線寬較大的特點，理論上分析採用棱鏡、光柵、標準具等線寬壓窄元件來壓窄輸出參量光線寬，分別獲得了小於ztun 、 0 . snm 、 0 . 06nm的輸出線寬。
  10. Switching network module controller snm ctl

    交換網路模塊控制器
  11. Standard guide for laboratory evaluation of automatic pedestrian snm monitor performance

    行人區自動snm監視器性能的實驗室評定的標準指南
  12. If a set of standards is prepared incorrectly, it is a waste of both time and money ; in addition, snm waste is generated and it must be disposed of or recovered

    如果樣品制備得不合格，不僅是時間和金錢的浪費，還會產生放射性廢物，這些廢物必須回收或處置。
