The principle of vibrator is to introduce scattered energy to underground in a comparatively long time, and collect the energy through correlation and compress it into a narrow pulse. the portable high - frequency vibrator system, developed by key lab of geo - exploration and instrumentation ( jilin univ ), ministry of education, generates chirp signal and accumulates energy through a long - time bestiring. according to the characteristics of vibrator, the seismic recorder that operates on - line with vibrator must have these functions as follow : first, it must have the ability of recording a great quantity of data. second, it must have assistant channels to sample reference signal. third, it must have the function of data correlation in real - time
可控震源利用可控的小能量、長時間激發波來實現沖擊震源瞬時產生的大能量激發波。在利用可控震源進行地震勘探時，要求地震儀長時間記錄地震信號，這對地震儀的采樣長度提出了很高的要求。受存儲量和數據傳輸速度的限制，絕大多數地震儀很難對如此大的數據量進行記錄，同時，可控震源要求地震儀有兩個輔助通道並且具有數據相關功能，目前國內還沒有出現滿足要求的地震儀產品。 -

First, we make the basic need of magnetic circuit clearly, present the theory formulation for permanent magnetic circuit of radial polarization using the method of analyzing the theory of magnetic circuit of axis polarization, and program the calculational programme to simulate the magnetic field of magnetic circuit applying finite difference method. then we continue to study using the adult soft of femm of calculation magnetic circuit magnetic field, consider many factors affecting it, get a great lot of data and curves, give some better magnetic circuit structures for reference at our laboratory. in the end, with the condition of our lab, we measure the permanent magnetic circuit completed, then the experimental and calculational simulation results have been discussed and analyzed
本文首先闡述了磁路計算及設計的基本要求，利用分析軸向永磁體磁路理論的方法，推導出了求解徑向磁化磁路的理論方程，應用有限差分法，編制了計算程序，對磁路的磁場進行了模擬；然後利用比較成熟的計算磁路磁場軟體femm作深入研究，考慮了影響磁路磁場的多種因素，得出了大量數據和曲線，給出了幾組比較合理的磁路結構，可供實驗的參考；最後，結合本實驗室條件，對現有永磁體磁路進行了冷測，將測試結果和計算模擬結果作了比較，並進行了討論和分析。 -
Abstract : the method of using formaldehyde buffer solution a b sorption - hydrochloric pararosaniline spectrophotometry to determine sulfur diox ide in air has higher sensitivity and good selectivity, and prevents from adoptin g mercurial absorbent. but the conditions in lab are not well controlled, the v alue of reagent blank and standard curvilinear slope can ' t accord with the one s tipulated in “ methods for air and waste gas monitoring and analysis ”. some opra tional techniques for so2 determination in lab are introduced for reference
文摘:以甲醛緩沖溶液吸收-鹽酸副玫瑰苯胺分光光度法測定空氣中的二氧化硫，方法靈敏度高，選擇性好，避免了使用含汞的吸收液，但如果實驗條件控制不好，試劑空白值及標準曲線的斜率就會不符合《空氣和廢氣監測分析方法》中規定的值，本文著重從操作技巧方面對二氣化硫測定的實驗室質量控制進行分析，僅供參考。 -
Based on the engineering geologic investigation reports of 22 buildings and the author ' s own tests in lab ( which includes 18 groups of conventional test and compression test, 8 groups of unconsolidated undrained triaxial test and 8 groups of quick direct shearing test ), taiyuan silt is studied in the paper. firstly, the variability of silt indexes is analyzed. the analyses results show the change laws on variability, in addition, the average value and variability coefficient ranges of silt indexes are given for reference
本文以太原地區粉土為研究對象，在收集、整理了22個建築工程場地勘察報告和作者室內試驗成果（ 18組常規試驗和壓縮試驗、 8組不固結不排水三軸剪切和8組直剪快剪試驗）的基礎上，對太原粉土作了以下方面的分析研究：首先研究了粉土工程性質指標的變異性，得出了變異系數的變化規律，給出了各工程性質指標均值和變異系數范圍的建議值。 -
Based on the experience of building dioxin analysis lab at tsinghua university, the lab designs were discussed for the reference of future dioxin analysis lab construction in our country, including planar design, air conditioner and ventilation piping system set - up, automatic control system set - up, power supply, lab safety and sanitation set - up, lab decoration, major instrument installation
