  1. The results of the experimental tests show that nh4cl and k2hpo4, kh2po4 are the most available nutrents to our isolates when they are degrading oils. the most suitable experinment condition is : temperature being 30 c, initial ph being 7 - 8, the shaking rate of the culture flasks is 180 r / min, the concentration of nacl is 1 %. the biodegradation results have shown that our 6 isolates have the effective degradation capability to crude oil ; within 6 days the transforing rate of oil by each single strain is more than 60 %

    本研究分離出的6株菌，初步鑒定結果為： sy1為微桿菌屬、 sy2為諾卡氏菌屬、 sy3和sy5為假單胞菌屬、 sy4和sy6為芽孢桿菌屬；實驗結果表明， 6菌株的最佳氮源為氯化銨（ nh _ 4cl ） ，最佳磷源為磷酸氫二鉀和磷酸二氫鉀的混合物，最適生長條件為：溫度為30 ，初始ph值為7 8 ，搖床轉速為180r min ，鹽（ nacl ）濃度為1 ；通過降解實驗得出6株菌對原油都有較強的降解能力，單一菌株在5天後的原油降解率都高於60 ， 6株菌對原油的生物降解反應符合一級反應動力學特徵。
  2. The basis of these technologies is cellular matrix. it must have biocompatibility, surface compatibility, structure compatibility. biodegradation, and it also can be sterilized. because people can control the synthetic matrix appearance, dimension, intensity degradation rate and three dimensional, they used to use it. but it also brings biocompatibility and infection

    過去所用的支架一般為合成支架，它的優點是人們可以隨心所欲地控制支架的形態、尺寸、強度、降解時間、降解速度及三維結構，並可成批生產，但也帶來了諸如：生物不相容性，感染問題等，而且合成支架在表面相容性和結構相容性上有諸多不盡如人意之處。
  3. The main effect factors include : 1. microbial species, which seem to have different degradation rate under varied circumstances and n - alkanes ; 2. physical and chemical properties of crude oil itself, which have an important effect on biodegradation, such as conglutination, boiling point, refractive index, ingredient and concentration of the oil ; and 3. culture condition of microorganism, under which the degrading activity of microorganism will be affected by surfactant, light condition, sorbent, nutrition, co - metabolite, oxygen, temperature and salinity during the inoculation of selected or indigenous microorganisms

    其中主要影響因素包括：菌種的影響，菌種在不同的環境中和對不同碳鏈長度的碳氫化合物表現出不同的降解效率；石油物質本身物理化學特性的影響，如石油物質在水體或土壤中的濃度以及石油的粘度、沸點、折射率等特性；生存環境條件的影響，在接種入高效率的降解菌或利用土著微生物進行降解時，降解率受到生存環境中各種條件的影響，如表面活性劑、光照條件、吸附劑的利用、營養鹽、共代謝底物、氧氣、溫度、鹽度等。
  4. In this work, pluronic f127 was used as a progen and different biodegradation rate and surface property as amorphous calcuim phosphate, a - calcuim triphosphate, - calcuim triphosphate and a / p - calcuim triphosphate were selected to make three - dimensional porous composites with plla. in the phase separation of pure plla or cp / plla composite system the ppo block of pf127 can aggregate plla clew to induce phase separation. this resulted big round pores of 50 ~ 300 m and uniform ladder - like structure of 400 ~ 1000 m

    具體結果如下：浙江大學碩士學位論文在單純的聚乳酸以及鈣磷酸鹽/聚乳酸復合體系的相分離過程中， pf127的ppo鏈段對plla鏈段有聚集作用，促進相分離過程，在不同溶劑中分別可得到孔徑在50一300林m的較大的圓孔和有序度為400一1000林m的梯狀孔，孔隙率為80 % ~ 93 % 。
