本試驗採用石蠟切片研究了沙芥發芽期、幼苗生長期各器官形態及解剖結構的變化過程；並對采自鄂爾多斯市野生沙芥花、果實、種子及人工栽培的葉片旺盛生長期、葉片生長衰退期的根、莖、葉等材料進行了形態及解剖學研究，結果表明：沙芥發芽期根、莖、葉各器官內組織已開始分化；幼苗期已分化出發達的輸導組織及貯水組織；葉片旺盛生長期各器官具有發達的輸導組織，但機械組織不發達，因此沙芥的根莖葉適于食用。Applying relative arithmetic to all kinds of faults and calculating off - line, we can master time - distance relation chart for all kinds of faults. computation indicates : when transmission lines occur faults, the data window of protection algorithm consisting of prefault and postfault data at the same time has important significance. the following methods are useful to achieve the inverse time characteristic : calculating impedance by using flourier in a full cycle, calculating work voltage by using fault component, calculating the torque created by a phase comparator or a magnitude comparator
實際的計算表明：輸電線路發生故障后，用故障前後的數據同時充滿保護演算法的數據窗，對于快速切除近區故障具有很重要的意義；同時利用故障前後的數據，下述方法可以比較好地實現距離保護的反時限特性：直接用全周傅里葉演算法進行阻抗計算；採用工頻變化量阻抗繼電器進行工作電壓的計算；採用轉矩的思想進行轉矩的計算。Propeller is a critical part of crystallizer, the geometry shape and dimension of which determine the flow field in the crystallizer
攪拌槳是攪拌釜式結晶器的重要部件，攪拌釜內飽和溶液的整體流動形式與攪拌槳的葉剖面形函數和槳的結構參數密切相關。The turbocharger noise is formed by the rotation noise resulting from the periodical air cutting of the fan blade and the turbulent noise of high - speed gas flows. as a continuous high frequency noise, it mainly falls between the 500 to 10 000 hz range
渦輪增壓器的噪聲是由於葉片周期性地切割空氣產生的旋轉噪聲和高速氣流形成的湍流噪聲而形成的，是一種連續性的高頻噪聲，主要分佈在500 ~ 10000hz的頻率范圍。In addition, the pith of root and stem is flourishing for prosperous growth period and declining period, the vascular tissue storing the nutrient and providing the nourishment for the biennial plant in next year from abnormal secondary growth is developing in pith, unusual structure eg. epidermis and vice - epidermis, bubble form cell, short pipe numerators and wreath grid types leaf etc. in each organ of pugionium comutum ( l. ) gaertn. had been formed to adapt to dry environment, so the characteristics on appearance and anatomies in pugionium cornutum ( l ) gaertn. has closely of relation with its anti - drought and its adapting to desert environment
此外，葉片旺盛生長期、衰退期根莖具發達的髓，髓內有異常次生生長形成的維管組織，貯藏養分，為沙芥次年形成二年生植株提供營養，沙芥各器官在解剖結構方面都形成了特化結構如具表皮及副表皮、泡狀細胞、短的導管分子及環柵型葉等以適應乾旱的環境，因此沙芥各器官的形態及解剖特點與其抗旱、適應沙漠環境有密切的關系。Finally, the wave equation of the electromagnetic field of this kind damper is derived from the maxwell ' s equation. the magnetic flux density at the boundary is assumed to be harmonic, so the analytical result of the wave equation is solved. when the rotor rotates, eddy currents flowing inside the conducting material field are caused
最後，應用ahrens的電磁軸承簡化模型，從maxwell方程出發推導了應用於本文所述的被動式電磁阻尼器的波動方程，並用傅立葉級數把矩形磁場展開的諧變磁場作為磁場的邊界條件，通過求解波動方程得到磁場的解析解，從而計算了阻尼器對轉子的電磁力和由渦流引起的切向力產生的阻尼器附加功耗。So to develop a new type of transformer calibrator which has the high precision and the high degree of automation is significative. for the outdated transformer calibrator is widely used, this paper analyzed the theory of previous calibrators and proposed an idea of designing a new type of intelligent calibrator, based on the theory of measure the difference, adopt the project of dsp and mcu structure, also use high speed a / d electric chip. after the design of hardware circuit diagram, adopt the theory of fft and quasi - synchronous sampling method to reach the demand of precision. this paper discuss the intelligent development of transformer calibrator, achieve some success in the study
本文針對國內市場目前普遍使用的老式互感器校驗儀的現狀，提出了智能型互感器校驗的研製思想，並詳細講述了其理論依據和實現過程，提出了切實可行的方案：基於測差測量原理，進行基於dsp和mcu雙cpu架構、並採用高速a / d的硬體電路設計，並在此基礎上採用快速傅立葉變換和準同步采樣演算法，並完成相關的軟體演算法框圖設計，對互感器校驗儀的智能化發展進行了有益的探索，取得了具有實用意義的成果。Could this leaf structure correspond to some of the organs previously cut and be part of the same plant ? circle the correct option
