另外,基於對匯率不完全傳遞的論證,本文後半部分以此為主要前提假設,通過對donbush ( 1976 )匯率超調模型的拓展和對新凱恩斯主義經濟學中價格粘性理論的創新,用動態一般均衡模型推導出了在匯率不完全傳遞條件下的匯率短期行為路徑,認為貿易品價格對匯率波動的不敏感性會導致更加顯著的匯率超調行為。At first, modeling of these divvies by rate equations to obtain expressions for threshold and slope efficiency is given. on the case of this theory, the large numbers of literatures and datum are consulted, and the laser is home studied. through rationally selecting and improving the reflector surface, ensuring the beam quality, increasing farthest the absorption path, and improving effective pumping frequency ; through designing the water cooler of yag bar, the volume of laser is half the same internal and international production, and the output power is get to the extremum of the same international production
並在此基礎上查閱了大量文獻和資料,對該種激光器進行了深入的研究,通過對yag棒直徑的合理選取併合理地改進反射鏡面,從而既保證了光束質量又最大限度的增加了吸收長度,有效的提高了泵浦效率;在不影響泵浦的前提下,通過有效縮短yag棒的長度減小輸出損耗;對yag棒的水冷系統進行優化結構設計,使激光器體積減小到國外同類產品體積的一半,而輸出功率已達到國外同類產品的極限值。On the basis of computer simulation, the relationship among plasma channel, plasma configuration and the final crater are clarified
根據計算機模擬實驗,得出了短、長脈沖加工時瞬時放電通道半徑、放電通道位形半徑以及最終放電痕半徑三者之間的關系。The variation of minute bubbles is monotonic, whereas there is peak for the case of phase splitting drop
但它們對短波選擇的程度隨粒子半徑變化是不同的,小氣泡是單調的,而分相液滴會有極值出現。If it keeps up appropriate space centering on household house and within the radius between house and arable land, times should n ' t exceed 20 minutes unit
以農戶住房為中心,住房到地塊間的距離為半徑,保持適當短的距離,以時間計,應不超過20分鐘。When a larger waist w of the incident gaussian beam and a shorter focal length / of the lens are chosen, we can obtain an extremely - small dark spot size of the focused hollow beam, even approach the diffraction limit
當選擇較大的入射準直高斯光束的束腰w _ 0和較短的薄透鏡焦距f時,可以在焦平面上產生一個很小的dss (或束半徑r _ 0 ) ,甚至可以接近衍射極限。The drilling technology of tk406h sidetracked short - radiused horizontal well
側鉆短半徑水平井鉆井工藝技術This is understandable in terms of conservation of angular momentum. as the radius of rotation decreases, the rotational speed will increase accordingly
