  1. The results suggested that the ph value, the type of monomers, the type, concentration and surface properties of inorganic nanoparticles, the type and concentration of emulsifier have a great influence on the encapsulating emulsion polymerization and the obtained latex stability. if selecting cationic emulsifier ( ctab ), low water soluble monomers ( such as ba, st ) and hydrophobic nano - silica, the inorganic nanoparticles would be encapsulated by polymers through ultrasonic irradiation successfully under alkalescent condition

    系統研究了ba 、甲基丙烯酸甲酯( mmal苯乙烯舊t )以及它們的共聚體系在超聲輻照作用下包裹聚合的主要影響因素,結果表明: ph值、單體的種類、無機納米粒子的種類、濃度及表面性能、乳化劑的種類及濃度等對超聲輻照包裹乳液聚合以及復合體系的穩定性有較大的影響。
  2. Increasing ultrasound intensity in the range of cavitation threshold and cavitation peak value, decreasing monomer concentration and increasing the temperature make the induction period shorter. under optimized reaction conditions, the conversion of ba can reach 90 % in 11 min at high n2 flow rate the viscosity average molecular weight of the obtained pba reaches 5. 24 106. the molecular weight of pba varies with ultrasonic irradiation time, indicating that the ultrasonic induced emulsion polymerization is dynamic and quite complicated, polymerization of monomer as well as degradation of polymer occurs concomitantly

    一、實現了無常規化學引發劑存在下的超聲輻照引發丙烯酸正丁酯( ba )間歇乳液聚合,制備了pba納米粒子,在11min內轉化率達到90 ,分子量達5 . 24 10 ~ 6 ,隨反應時間的延長而降低,表明超聲輻照引發乳液聚合是一個動態的復雜過程,單體的聚合和聚合物的降解同時發生。
  3. Nitrogen dioxide and sulfur dioxide and formaldehyde, three kinds of common contaminating gases, were selected as treatment subject. the influence factors on the rate of photocatalytic degradation such as intensity of uv irradiation, humidity and initial mass concentration were investigated in detail

    實驗選擇比較常見的甲醛、二氧化硫、二氧化氮三種污染氣體為處理對象,主要考察了光強、濕度、初始濃度對其光催化降解速率的影響情況。
  4. It was also noted that irradiation treatment with low dose ( 10gy ) of y rays exerted slight stimulating effects on callus induction and formation of embryogenic calli in particular. production of embryogenic calli was obviously promoted by addition of 0. 1 ~ 0. 2mg / l bap or 2. 5mg / l cuso4 5h2o, or enhancement of sucrose concentration to 60g / l in subculture medium

    在繼代培養基中添加0 . 1 0 . 2mg lbap或2 . 5mg l硫酸銅,或將繼代培養基中蔗糖濃度提高到60g l能促進胚性愈傷組織發生,提高胚性愈傷組織頻率。
  5. The damage of wheat seedlings induced by enhanced uv - b radiation in physiology can be repaired partly by he - ne laser irradiation with enzymatic and non - enzymatic system including of decreasing the mda concentration, increasing the contents of asa, gsh, uv - b absorbing compound, and the activities of sod, cat, pod

    He - ne激光輻照可使uv - b輻射后小麥幼苗mda的含量明顯減少; asa 、 gsh含量明顯增加; sod 、 cat 、 pod等酶活性增加。說明he - ne激光可通過酶促與非酶促抗氧化系統,增加小麥幼苗在生理水平對輻射損傷的修復能力。
  6. Influence of low power diode laser irradiation on the minimal inhibitory concentration of drug resistant staphylococus aureus and pseudomonas aeruginosa

    低功率半導體激光照射后耐藥金黃色葡萄球菌與銅綠假單胞菌的耐藥性變化
