The key components in laser gyro is he - ne ring laser, and the reciprocal action theory between light and medium is the base in studying the ring laser, use the lamb half classical theory, and on the base of density matrix theory, the optical brounch equation was established, which described the movement of amplifying medium atom in the ring syntonic cavity, and according to the medium polarize theory the self consistent equations was deduced, which describe the light intensity and phasic of the counter - propagating wave. on the basis of this equations, adopted the simulation software matlab and virtual instrument programming language labwindows / cvi, we can do some simulated experiments in study the phenomenas such as amplify and dispersive characteristic of medium, mode pushing effection, burned hole effection and pattern competition, lock - in of frequency and the characteristic of light intensity and phasic of the counter - propagating wave in laser gyro
激光陀螺的核心部件為he - ne環形激光器，而掌握光與介質的相互作用理論是研究激光器的關鍵，採用拉姆半經典理論為主，在密度矩陣理論的基礎上，推導環形諧振腔中描述he - ne氣體增益介質原子運動的光學布洛赫方程，運用介質極化理論得出描述激光陀螺反向行波的光強、位相所滿足的自洽場方程組，在此基礎上，運用matlab模擬軟體和虛擬儀器編程語言labwindows / cvi ，對激光陀螺中的介質增益色散特性、頻率牽引效應、燒孔效應及模競爭、閉鎖效應及環激光的光強和相位特性進行模擬試驗研究，並且運用全量子理論，對激光工作原理進行分析，得出二能級系統單模輻射場的光子數密度分佈，得出激光場的光子統計分佈，模擬激光場的動態建立過程。The system measures photosynthesis rate by using infrared co2 gas analyze method. it has two work modes : open route and close route. it can measure the leaf photosynthesis rate, transpiration rate, stomata conductance and co2 thickness in cell clearance etc parameters about plant physiology
本文研究設計了測定光合、蒸騰速率的主從式虛擬儀器系統，系統採用紅外線分析法測定光合速率，設置有開路和閉路兩種測定方式，可以測量植物葉片的光合速率、蒸騰速率、氣孔導度和細胞間隙co _ 2濃度等與植物光合作用相關的參數。It has a higher incidence of incarceration and mortality rate than other types of hernias
比起其他種類的疝氣來說，閉孔疝氣有更高機率造成壞死性腸嵌塞及死亡。The plantlets grew much better in terms of root development ; the root activities, photosynthesis, regulating stoma and transpiration of them were significantly enhanced
主要表現在：植株健壯且根系發達，有大量的側根形成；植株的根系活力、光合作用、調節氣孔開閉和控制蒸騰速率等方面顯著提高。Then a tentative plan came to our brains, is it possible for us to assure guard cells to open when water supply is enough, and close rapidly when plants come across drought stress by regulating expressional pattern of genes
我們的設想是：當水分供應充足時，氣孔盡最大限度開放，吸收co _ 2 ，增加光合產量；當乾旱來臨時，氣孔迅速關閉，減少水分喪失，提高作物的水分高效利用率。分享友人
