  1. 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。
  2. The reaction of threshold on linewidth of ring ' s output light is pointed out. this provides a new auxiliary method to determine the threshold

    最後提出一種利用有源腔內ase輸出光的線寬變化特徵來判斷有源光纖環形腔閾值點的輔助方法。
  3. The relative momentum of two final particles and the cross section are zero at the threshold energy for an endothermic reaction, while the relative momentum of two initial particles is zero and the cross section at the threshold energy for an exothermic reaction is infinite

    在吸熱反應的閾能處，出射粒子的相對動量以及截面均為零。在放熱反應的閾能處，入射粒子的相對動量為零，截面趨于無窮大。由於強子的動量僅提供如此低的質心系能量，強子物質中x 。
  4. This paper stuffed with twelve important grain and vegetable crops, studied the injury symptom, dose reaction, injury threshold value and influential factor of main pollutant so2 on various plants, tested the dynamic transformation of pod, cat, mda, soluble protein, free pro and chlorophyll of resistant plant and sensitive of these physiological biochemical transformation with plant resistant ability. meanwhile, simply studied the protective role of the five compounds on plant. the result indicated the followings

    本實驗以12種重要的糧食和蔬菜作物為研究對象，研究了主要大氣污染物二氧化硫（ so _ 2 ）對不同植物的傷害癥狀、劑量反應、傷害閾值以及影響因素，測定了抗性和敏感植物在受到so _ 2污染后植物體內過氧化物酶（ pod ） 、過氧化氫酶（ cat ） 、丙二醛（ mda ） 、可溶性蛋白質、游離脯氨酸和葉綠素的動態變化，並分析了這些生理生化變化和植物抗性的相互關系，同時還對5種化合物溶液對植物的保護作用進行了初步研究，結果表明： 1
  5. It is shown that the results calculated using the ccdwa are agreement with one of the accurate quantum mechanics employing the same potential. quantum mechanical tunneling is important in near threshold, and classical trajectory calculation is not good for prediction of the cross sections. the reaction cross sections calculated using different potentials is different, which show that the investigation of reaction cross section can provide evidence for test of accuracy of the potential energy surface

    研究發現：勢能面相同時用ccdwa方法計算的截面和公認精確的量子力學結果比較符合；閾能附近的量子力學隧道效應較為顯著，準經典彈道方法不能很好的預言其截面；用不同勢能面計算的反應截面有差別，說明反應截面的研究能為檢驗勢能面的準確性提供依據。
  6. 05. 02 test method for reaction threshold temperature of liquid and solid materials

    液體和固體材料反應的極限溫度的試驗方法
