  1. There was no difference in other biologic characteristic of mscs between the two separation method, such as cell anchorage ratio and clone formation ratio. ( 2 ) plga film presented uniformity frame with no protuberance and fissure under scanning electron microscopy ( sem ). big aperture with smooth wall and average 400 m i n size running - through each other was observed in porous plga substrate, around the big aperture there were many round micropores about 5 m size. all of the structure were equal and uniform, which satisfied the further research work. ( 3 ) mscs adhesion at earlier time was promoted by biotiegenrafter 3h, cell number was ( 1. 5 0. 18 ) 105 in the plga film coated with biotiegen group, which was significantly higher than that in plga film group ( p < 0. 01 ) and higher than that in coverslip group ( p < 0. 05 ), which cell number was ( 1. 04 0. 21 ) 105. after 6h and 12h biotiegen could not promote cell adhesion, and cell proliferation and alkaline phosphatase ( alp ) activity were not promoted dramatically during 9 days. ( 4 ) cell adhesion was promoted by fibronectin or collagen type i

    G ） i型膠原、纖維粘連蛋白促進細胞增殖，細胞接種后3 、 6 、 gd三個檢測時間點，實驗組細胞均明顯高於對照組。與1型膠原相比，纖維粘連蛋白刺激作用更強。 ） i型膠原、纖維粘連蛋白尚能誘導mscs細胞向成骨細胞分化，不僅表達成骨細胞標志物ocn 、 alp 、 opnmrna ，而且堿性磷酸酶活性明顯增高，堿性磷酸酶及鈣結節7第四軍醫大學博士學位論文一染色均強陽性， i型膠原組mscs細胞堿性磷酸酶活性較fn組更高，有顯著性差異；同時，兔疫組化染色表明，經纖維粘連蛋白作用的mscs1型膠原表達陽性。
  2. Sige simox : oxygen ions with high dose were implanted into sige grown directly on silicon substrate for the first time, and sige - oi novel structure was formed successfully with additional high temperature annealing ; it has been confirmed that oxygen implantation with 45kev, 3 1017cm - 2 and annealing at 12500c in ar + 5 % o2 for 5 hours, are fit for the formation of sige - oi structure ; ge loss during the high temperature annealing has been observed, which is originated from ge volatility and ge diffusion ; it has been proposed to use nanoporous layer induced by h + / he + implantation to surppress ge diffusion and to use surface oxidation to overcome the upper limit of sige simox. sige smart - cut : hydrogen ions were implanted into sige material and followed by high temperature process ( 4000c to 7000c ) ; blistering study was done and suggested the possibility of sige layer transfer by smart - cut technology ; it is concluded that the bubble formation is easier in sige than in si, and the strain in sige / si and the difference of binding energy in sige and in si could possibly contribute to this effect. behavior of sige / si implanted with hydrogen : gave a detailed study on sige implanted by beamline or phi hydrogen implantation ; it has been found that great strain is introduced into sige by hydrogen implantation and this strain could be alleviated by high temperature annealing ; both for conditional beamline implantation and piii hydrogen implantation, 600 is appropriate for the post - implantation treatment

    Sige - simox工藝方面：首次採用硅（ 100 ）襯底上直接外延的100nm厚sige的樣品中注入高劑量的o離子，通過退火處理成功制備了sige - oi新結構，即sige - simox工藝，證實了以45kev注入3 10 ~ （ 17 ） 7cm ~ （ - 2 ）劑量的氧離子，隨后在氧化層的保護下經1250 ， ar + 5 o _ 2氣氛的高溫退火（ 5小時）過程，可以制備出sige - oi新型材料；實驗中觀察到退火過程中的ge損失現象，分析了其原因是ge揮發（ ge通過表面氧化層以geo揮發性物質的形式進入退火氣氛）和ge擴散（ ge穿過離子注入形成的氧化埋層而進入si襯底中） ，其中ge擴散是主要原因；根據實驗結果及實驗中出現的問題，對下一步工作提出兩個改進的方案：一是通過在si襯底中注入適量h ~ + / he ~ +形成納米孔層來阻斷ge擴散通路，二是可以通過控製表面氧化來調節安止額士淤丈撈要表面sige層中的ge組分，從而部分解決sige
  3. We found that different level coriolis acceleration stimulation had no significant influence on the duration of the illusion but had some influence on the pattern of the illusion, the intensity of ci increased with the levels of coriolis acceleration stimulation, and no significant difference was observed on nystagmus beats, peak slow phase velocity, mean slow phase velocity, time constant of slow phase velocity decay, duration of eng among different coriolis acceleration stimulation, but the direction of eng is consistent with the pattern of ci

    結果發現：不同強度的科里奧利加速度刺激對錯覺形態具有一定影響，錯覺持續時間、錯覺強度隨科里奧利加速度的增加而增加，不同科里奧利加速度刺激下的眼震電圖，其眼震方向與錯覺形態是一致的，但無論是水平性眼震還是垂直性眼震，眼震次數、最大慢相速度、平均慢相速度。慢相速度衰減時間常數、持續時間等參數均無顯著性差別。
  4. Blinking of the sers spectra and the poisson statistical distribution of the raman signal were observed. moreover spectral diffusion of raman shift with time was reported by the first time according to our knowledge, which could be due to the difference of interaction between varied single molecules and varied silver particles surface, for instance, due to the different adsorption states of dab molecules on the silver surface, which should be a powerful evidence for single molecule detection by sers

    我們採用一種簡單的方法，將含有dab分子的銀膠體溶液滴在鋁箔上，激發光聚焦在液滴上直接進行測量，觀察到了分子sers信號的「 blinking 」現象，並首次報道了其sers拉曼頻移隨時間產生波動，這是由於個體分子和銀納米顆粒的相互作用及其在銀納米顆粒表面的l吸附狀態不同而導致的。
