In this paper, 6013al / sicp / gr metal matrix composite ( mmc ) was produced by spray codeposition, by means of changing the medium of quenching, influence of five types of heat treatment system ( furnace cooling, air cooling, water quenching, dry ice quenching, liquid nitrogen quenching ) and different aging temperature on the damping was studied systematically
本文採用噴射共沉積方法制備了6013al sicp gr金屬基復合材料（ mmc ） ，通過改變淬火介質，較為系統地研究了五種熱處理制度（爐冷、空冷、水冷、乾冰冷及液氮冷）以及不同時效溫度（ 120 、 150 、 170 、 190及210 ）對6013al sicp grmmc阻尼性能影響。The paper fristly compared the fertile soil with the incinerated sterile soil on the number of micro - algae, soil ph value, soil organic matter soil available phosphorus and soil nitrogen. and then, the author put fertile soil, which included micro - algae, proportionally into sterile samples and cultivated them respectively under illumination condition ( micro - algae can live and reproduce ) and dark condition ( micro - algae will die in some time ). the above indices were measured in 0, 30, 60 and 90days respectively, the analyse of the interrelation between the change of micro - algae ' s number and the changes of soil ph value, soil organic matter, soil available phosphorus and soil nitrogen indicated : ( l ) soil micro - algae which were native to fertile soil conld adapt to the changed circumstance and light acted as a decisive role to the distribution of soil micro - algae. under dark condition, the micro - algae ' s number declined gradually and went to zero in the end, while under illumination condition, on the 90th day, the micro - algae ' s number of per gramme was 6 - 7 times more than that of the beginning
本文首先對肥沃土壤與經高溫焚燒后的貧瘠土壤中的微藻數量、土壤ph值、有機質含量、有效磷含量和全氮量進行比較研究，然後將包含微藻的綠化苗圃地肥土按不同比例接種進入貧瘠土樣中，分別在光照條件和黑暗條件下進行培養，在0天、 30天、 60天和90天分別檢測以上指標，比較有光條件和無光條件下，即有藻條件和無藻條件下貧瘠土樣所發生的變化，並分別對微藻數量的變化與土壤ph值、有機質含量、有效磷含量和全氮量的變化之間做相關性分析，以評估肥沃土壤中的微藻接種進入貧瘠土壤后的生長情況以及對貧瘠土壤的改良作用。研究結果表明： （ 1 ）土壤微藻對環境有較強的適應能力，且光照對其分佈起了決定性的作用。
