結果表明三種復合膜均具有遠高於純tio _ 2膜的活性，主要歸因於復合膜材料中多金屬氧酸鹽和tio _ 2之間存在的協同效應，即作為強電子受體的多金屬氧酸鹽接受tio _ 2受光激發形成的導帶光生電子，延長了空穴-電子的再復合時間，同時自身仍具有光活性。That morning, finding that i was to be involved in the horrid disappointment he had prepared for the mutineers, he had run all the way to the cave, and, leaving the squire to i guard the captain, had taken gray and the maroon, and started, making the diagonal across the island, to be at hand beside the pine
今天下午，他發現原來本打算讓反叛者們空歡喜一場，沒料到把我也卷了進去。於是他急忙跑回洞穴，留下鄉紳照料船長，自己帶領葛雷和放荒灘的水手，按對角線斜穿全島直奔大松樹那邊。Long after the little birds had left their nests ; long after bees had come in the sweet prime of day to gather the heath honey before the dew was dried - when the long morning shadows were curtailed, and the sun filled earth and sky - i got up, and i looked round me
小鳥早已離開他們的巢穴，早露未乾蜜蜂便早已在一天的黃金時刻飛到歐石南叢中采蜜，早晨長長的影子縮短了，太陽普照大地和天空我才起身，朝四周看了看。Using the typical moled structure glass / dbr / ito / htl / eml （ etl ） / al ， the el spectrum narrowing, intensity enhancement in the normal direction as well as emission intensity redistribution in space are observed. by the introduction of single layer silver film instead of the dbr / ito multilayer, a ( / 2 - length cavity is obtained. using this kind of microcavity, three - color single mode pl from a single material alq and three - color single mode el from double layers pvk / alq are achieved for the first time
通過以金屬銀替代多層結構的dbr / ito ，既作為反射鏡，又作為el器件中的空穴注入電極，設計出腔長只有（ / 2的超短微腔，採用同一種寬譜帶材料alq作為光發射層，首次報道了三基色單模光致發光和pvk / alq雙層結構的三基色單模電致發光。Mg ions were implanted on mg - doped gan grown by metalorganic chemical vapor deposition. the p - type gan was achieved with high hole concentration 8. 2810

的p -型gan 。首次報道了實驗上通過mg離子注入到mg生長摻雜的gan中並獲得高的表面空穴載流子濃度。Ben, in his long, lonely wanderings about the island, had found the skeleton - it was he that had rifled it ; he had found the treasure ; he had dug it up it was the haft of his pickaxe that lay broken in the excavation ; he had carried it on his back, in many weary journeys, from the foot of the tall pine to a cave he had on the two - pointed hill at the north - east angle of the island, and there it had lain stored in safety since two months before the arrival of the hispaniola
長期孤身流浪在海島上的本葛恩發現了那副骨架，並把它身邊的東西搜掠一空。發現寶藏的也是他，他把金銀財寶都掘了出來坑裡留下的鎬頭斷柄就是他的，把財寶扛著從大松樹下搬到海島東北角雙峰山上的一個洞穴里。不知返了多少越，終于在伊斯班裊拉號抵達前兩個月把所有的寶藏都安全運到那裡。Firstly on the basis of twin shear unified strength theory and spherical cavity expand theory it is established the expression about target defense force, given the equations of rod projectile penetrate and impact velocities on ceramic / composite target under the same pressure and verified through the experiment. secondly the analysis model of ceramic / grfp / steel composite multi - layer target penetrate depth employing above differential equation of target defense force, penetrate velocity and rod velocity. there are two team of experiments which testify separately the penetrate depth and effect with different length - to - diameter
首先，基於雙剪統一強度理論和球型空穴膨脹理論建立了靶板抗力表達式，並通過壓力相等條件給出了桿式彈侵徹陶瓷復合靶板的侵徹速度與撞擊速度的表達式，最後用試驗進行了驗證；其次，利用上面的靶板抗力表達式、侵徹速度、彈桿速度的微分方程，建立了陶瓷/玻璃鋼/鋼板復合多層靶板侵徹深度分析模型，分兩組試驗對侵徹深度、不同長徑比的侵徹效果進行了驗證;最後，建立了桿式彈垂直侵徹陶瓷多層復合靶板的工程模型，給出了預測靶板抗彈性的k 。Moreover, the sio2 / tio2 composite thin film showed the lowest pl intensity due to a decrease in the recombination rate of photo - generated electrons and holes under uv light irradiation, which further confirmed the film with the highest photocatalytic activity at 700 c. when the calcination temperature was higher than 700 c, the decrease in photocatalytic activity was due to the formation of rutile and the sintering and growth of tio2 crystallites resulting in the decrease of surface area
同時，此時sio _ 2 / tio _ 2復合薄膜的熒光光譜顯示最低的熒光強度，這表明此時薄膜中的光生電子和空穴的復合速率最低，因而更有利於物質的光催化降解。當熱處理溫度高於700時，武漢理工大學碩士學位論文薄膜的光催化活性下降，這是由於薄膜中晶相二氧化欽的燒結和成長導致樣品的表面積下降以及金紅石相的形成。However, typically we fit just three and this can drop to as few as two for a low - downforce circuit, such as monza in italy
