  1. Based on the spectral irradiance measured with the sun - atmosphere ultraviolet spectrum radiometer ( sauvs ) developed by the institute of atmosphere physics and the changchun institute of optics and fine mechanics, chinese academy of sciences, measuring the direct and scatter irradiance spectrum of ultraviolet waveband which arrives in beijing global surface, giving a method of retrieving the aerosol optical depth ( aod ) and put up with primary results that exponential function can fit the retrieval results according to its visibility, putting forth different coefficients and functions on variable visibility, also giving a primary analysis on the aod in dust - storm day and some contrast between sun - day and dust - storm day, analyzing the ratio between scatter and total irradiance, and its relationship with atmosphere mass and total atmosphere optical depth, lastly contrasting with the survey results by aeronet beijing station, the results of retrieval is in reason, this work gives some help in researching the co - effect of aerosol - radiance - climate and makes preparation for further survey on the radiance characteristics of dust

    利用中國科學院大氣物理研究所與長春光學精密機械研究所合作研製的太陽?大氣紫外光譜輻射計（ sauvs ） ，測量到達北京地表的太陽直接和散射紫外光譜輻射，導出了大氣氣溶膠的光學厚度。初步結果表明：北京紫外波段大氣氣溶膠的光學厚度在絕大部分情況下隨波長的增加而單調減小，用指數函數可以較好地擬合反演結果，統計得到了三個水平能見度狀況下擬合函數的系數值和公式表達式；初步分析了揚沙、浮塵、沙塵暴天氣條件下氣溶膠光學厚度的特點，並與一般晴朗天氣條件下的氣溶膠光學厚度特點做了比較分析；分析了太陽紫外譜輻射中散射輻射與大氣質量、大氣總光學厚度的定性關系和定量表達式；最後與全球氣溶膠監測網路（ aeronet ）北京站的資料做比對，表明反演結果基本合理。
  2. First, after investigation of two original strains " biological characteristics, we studied the main influence factors on protoplasts formation and regeneration in s. mycarofaciens and s. erythreus, and determined the best protoplasts formation and regeneration conditions of two original strains. the former shake - cultured in s " medium at 28 ?, 220r. min ~ ( - 1 ) for 24h, lysised by 3mg / ml lysozyme, keeping warm at 32 ? for 50 ~ 60min, regenerated on r _ ( 5 " ) medium, 28 ? for 5 ~ 6d. the latter used two - step culture, then used img / ml lysozyme keeping warm at 37 ? for ih ; the protoplasts were plated on r5 " regeneration medium at 28 ? for 5d

    首先在對兩親株的生物學特性進行了鑒定后，考察了影響兩親株原生質體形成和再生的主要因素，確定了生米卡鏈黴菌和紅黴素鏈黴菌原生質體形成及再生的最佳條件：前者用s培養基，在28 、 220r . min ~ （ - 1 ）培養24h后，用3mg ml的溶菌酶在32恆溫酶解50 60min ，得到的原生質體在乾燥的r5培養基上28倒置培養5 6天，可得到再生率在20左右的再生菌落；後者採用二級菌絲培養，用1mg ml的溶菌酶在37恆溫酶解1h左右，得到的原生質體也在乾燥的r5培養基上28倒置培養5天，即可得到再生率在20左右的再生菌。
  3. Under that condition the strain can produce the most concentration of the bioactive compounds. the physical and chemical properties of the actibacterial compounds have been studied, the results showed the bioactive substance has heat stable, acidity and weakly alkali stable. it can be dissolved in acid water, chloroform solvent, can not be dissolved in ethyl acetate, petroleum ether, alkali water. the result of thinlayer chromatography showed the bioactive compounds can give off blue and green fluorescence in the uv light. the paper chromatography demonstrate the bioactive substance may be a new construct compounds

    研究表明，該活性物質具有較強的熱穩定性， ph 9的條件下能穩定存在，但ph 12的強堿性條件下活性物質的抗菌活性幾近喪失；活性物質易溶於氯仿、酸性水、不溶於乙酸乙酯、石油醚、堿性水；薄層層析顯示活性物質在紫外光下能發藍綠色熒光等特點；由捷克八溶劑系統紙層析鑒定該抗菌活性物質不屬於四大類抗生素，可能為一新的抗菌活性物質。
