氣動窗口利用對激光器輸出波長沒有任何吸收作用的特殊氣體作為窗口工作介質，並根據氣體動力學部分相關原理，能生成一個具有與激光腔低壓和環境大氣高壓相匹配的壓力梯度、並把激光器低壓工作介質和外界大氣相隔離的「氣幕」 ，從而保證高能激光器的正常工作。Based on this observation, we develop a newton - filter method in such a way that at each step, the method generates a point such that either the objective function value or its gradient descreases sufficiently
此時，常用的線性搜索（如armijo搜索和wolfe搜索等）可能失敗。另一方面，不管目標函數的hessian陣是否正定， newton方向一定是目標函數的梯度的模函數的下降方向。Several influence factors to result plasma drift in hainan were analyzed. in this paper the characteristics of ionospheric parameters variation were analyzed systematically and some new results in storm - time such as seasonal behaviors were obtained ; it is the first time to investigate the ionospheric drift behavior in hainan and some new results was obtained, the relationships between each two plasma drift velocity components in storm time in hainan were found and the electric filed variation in hainan ionosphere also was obtained ; the results also show that there are big differences of the ionosphere parameters bo and bl obtained from the data with that obtained from the iri - 2001 applied for hainan ; a new phenomena was found during a strong magnetic storm, that a layer with very strong electron density and density grad was found during the recovery phase of the storm, its horizontal scale is beyond 100km and temporal scale is about 2 hours, this phenomena repeated 3 times continuously. a type of negative disturbance in high and low latitude but positive disturbance in east - asia also has been found
本文較為系統地給出了海南地區電離層的參數變化特徵，特別是得到了一些暴時與以往不同的季節特性；第一次給出了海南地區的電離層等離子體漂移特徵，發現等離子體漂移暴時擾動在三個方向上有內在的聯系，得到了電場變化曲線；研究結果還表明海南電離層的半厚指數和形狀參數等與國際參考電離層iri - 2001存在很大差別；通過對強磁擾動事件期間的參數變化特性分析發現，在磁暴恢復相期間海南地區電離層底部存在一個電子密度非常大的高密度區，高密度區底部電子密度梯度隨高度急劇增加，該區域的水平尺度可達100公里以上時間尺度約為2小時，連續出現過三次，這是一個在海南從來未發現的新現象；研究還發現了暴時東亞地區電離層擾動會出現高低緯負相而中緯正相的現象。Using matlab, the step response characteristics of the valve in the elevator system is simulated, comparing the effect of its performance with different structure parameters of the pipe rupture valve, such as hydraulic resistance, diameter of the valve, and spring rigidity, and comparing the valve ' s dynamic performance under different operating conditions, such as environment temperatures, number of passengers, and emergencies of the hydraulic system, so the paper offers a general and systematic analysis for the pipe rupture valve of the elevator system
另外，在液壓電梯不同的工況下，對該閥的動態性能進行了模擬對比研究，如不同環境溫度、不同乘客人數、不同液壓系統意外，以及不同的油液體積彈性模量，比較全面系統的分析了限速切斷閥在電梯系統中的性能，根據這些模擬結果，可以分析該閥正常工作的工況要求和環境要求。2005 the usda made improvements on the food guide pyramid. the new pyramid gives additional indications on the quantity of intake. the most obvious difference is also the addition of a person climbing the stairs on the left - hand side of the pyramid, emphasizing the balance between daily food intake and daily exercise, and suggests the importance of exercise to a healthy body
