  1. The results of numerical experiments, using the four - dimensional variational data assimilation system of the nonhydrostatic mesoscale model mm5, show that : the tangent linear model and adjoint model conducted by keeping the " on - off " switches the same as the basic state, can provide a good approximation of the first - order information to the nlm perturbation and a good descent direction for the minimization procedure ; switching on and off at every other time step in the kuo cumulus parameterization scheme do n ' t impact the convergence rate of cost function ; the existence of the switches do n ' t impact improvement to the mm5 model rainfall prediction because that not only specific humidity, but also wind, temperature and pressure are assimilated into the model

    非靜力中尺度數值模式mm5的四維變分資料同化系統進行的數值試驗結果表明: 「開關」變量保持與基態一致,所構造的切向線性模式能夠提供關于非線性模式擾動的一階近似,伴隨模式所計算的梯度值能夠為最小化過程提供較好的下降方向;郭氏降水參數化方案中對流每隔一個積分步的交替發生並不影響目標函數最小化的收斂速度; 「開關」變量的存在也不影響將風、溫度、氣壓和比濕結合起來同化對mm5降水預報準確性的提高。
  2. Since the analysis of the inverter and its control system is very complex, the frequency analysis, time domain analysis and control system is made in capacitance operated conditions limited to pressure of time and paper length. the research content can be summed up as follows : ( 1 ) a new equivalent circuit of dbd circuit ( dielectric barrier discharge ) that consider the consume of transformer, the on - off switching loses and so on is presented based on the ozonier powered by sine current source. as compared with the former equivalent, the new equivalent circuit can be depicted the actual ozone circuit accurately

    本文主要針對容性狀態下的臭氧發生器電源進行相關研究,研究內容包括以下幾部分: ( 1 )在正弦電流源供電的dbd型發生器的基波等效電路基礎上,提出了一種考慮電路雜散損耗(變壓器勵磁損耗、開關管開關和導通損耗以及其他元件的熱損耗)的改進型基波等效電路,並採用該等效電路得出了適用的臭氧發生器電源設計方法,實驗驗證了該基波等效電路具有工程設計精度高的優點。
