The rising temperature in the cave, the lamp - light ' s toasting and the convictive air made the humidity of the whole or part of the cave descend, which made the speleothem sightseeing dry, cracked and weathering. the acid air from the outer and the highly dense co2 would cause acid erode action to the speleothem sightseeing with water vapor. the existence of lamp - light offered a good chance for the lightloving plant to grow up, thus a lot of bryophyte covered the speleothem sightseeing
洞穴升溫、燈光的烘烤及空氣的對流致使洞穴濕度或局部濕度降低，使景觀產生乾裂、風化；氣流帶入的洞外酸性氣體及高濃度co _ 2在高濕的條件下，結合水汽對洞穴景觀產生酸侵蝕作用；燈光的存在為燈光植物生長提供了條件，使大量的苔蘚類植物生長于鐘乳類景觀的表面；洞外大氣粉塵的進入，給洞穴帶來了非常嚴重的破壞，粉塵在洞內高濕的環境下大量沉降，附著于鐘乳類景觀的表面，致使受污染面發黑，毫無光澤。Simulation results show that better atomization can be realized by enhancing the cavitation intensity via increasing the injection pressure difference or decreasing the nozzle inlet round angle - radius ratio
通過模擬計算可知，提高噴射壓差和減小噴孔入口圓角半徑都可以提高空穴強度，同時也發現提高噴孔長徑比可以使空穴在噴孔出口截面上分佈更為均勻。Principle : this product is make from self - heated point penetration medicament, heating time reach to 20 ~ 30 hours, the effect of outer applying eastern medicine is improved because the easy control of temperature, the temperature could be controlled between 40 and 58 ， fomentation of long time will make the efficient ingredients of eastern medicine penetrate into the certain point of skin, give a weight reducing effect
原理：本品採用了自熱透穴劑製作的中藥敷臍貼片，發熱時間達20 - 30小時，溫度易掌握，提高了中藥外敷的效果，溫度控制在40 - 58之間，長時間的中藥熱敷可使藥中有效的成份在通過熱能的作用下，滲透到皮膚指定的穴位上，達到減肥效果。Based on studying on the experimental forest of 14 - year - old castanopsis carlessi, the result showed that 10. 8 % increment in average dbh and 17. 8 % increment in volume occurred with digging the big holes compared to the simple holes ; 9. 4 % increment in average dbh and 14. 5 % increment in volume occurred with fertilized compared to the no fertilizer ; and 12. 1 % increment with appropriate high density compared to the general density
摘要對14年生米櫧試驗林研究分析表明：挖大穴、回表土比簡易挖穴平均胸徑增長10 . 8 % ，蓄積量增長17 . 8 % ；施基肥比不施肥平均胸徑增長9 . 4 % ，蓄積量增長14 . 5 % ；適當稀植比一般密度平均胸徑增長12 . 1 % 。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
應用mg離子注入mocvd法生長摻雜mg的gan中，在經過800 ， 1h的退火后，獲得高空穴載流子濃度8 . 2810Conformed by van der pauw hall measurement after annealing at 800 for 1h. this is the first experimental report of mg implantation on mg - doped gan and achieving p - type gan with high surface hole concentration
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。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。分享友人
