  3. It is very difficult to analyze flame radiation in the cylinder of a diesel engine by theoretical method since flame radiation is a function of many parameters, such as the combustion process, the geometrical description of the chamber, the soot formation and oxidation processes, the soot radiant temperature and soot absorption coefficient. the radiant property of the flame in a cylinder is dependent on the combustion process. but the thermodynamic state of real engine cycles can be analyzed from the pressure - volume diagrams in the cylinder. thus a new thermodynamic computational model is set up for the flame radiation in the cylinder of a diesel engine based on the indirect relationship between the flame radiation and the pressure - volume diagram of the combustion process in this paper. the flame radiant heat flux in the cylinder of a di diesel engine is calculated with the variation of crank angle by this model. compared with measured values, the result of the computational values shows the model is available to represent the effects of flame radiation

    柴油機缸內的火焰受諸多因素的影響,用理論分析法來確定它是相當困難的,由於柴油機缸內火焰特性依賴于缸內的燃燒過程,而燃燒過程中的實際熱力狀態又可用示功來分析,因此藉助於火焰與缸內熱力參數之間的這種間接關系,建立了一種計算柴油機缸內火焰傳熱的新模型,利用該模型對一臺直噴柴油機缸內火焰熱流量隨曲軸轉的變化情況進行了計算,將計算結果與實測結果進行了比較,表明該模型能較好預測缸內火焰傳熱量。
  4. 2 ) radar incidence angle and surface roughness correction : to make radar incidence correction and eliminate the surface roughness effects, a wide range of surface parameters ( soil moisture, surface rms height, correlation length, incidence angle ) was input to the ibm model to simulate the effect of surface roughness and radar incidence angle on the sensitivity of soil moisture to the radar backscattering coefficient. a simple model was established to simulate the effects of incidence angle and surface roughness. 3 ) establishment of soil moisture change inversion model : according to a modified ibm model simulation results, the bare surface backscattering coefficients can be expressed as a funtion of the dielectric component for a given surface roughness when the surface slope greater than 2. 0, which is valid for most nature surface : in above equation, r0 is the surface reflectivity at normal incidence

  5. After the discussion of the numerical simulation method based on the fdtd method and the pml technique, the motions of the charges and the electrical field lines were first employed to describe the radiation procedures of the pulse electromagnetic waves. then the causes of how the charges are accelerated and how the motion status of the charges are maintained were further studied from the angle of interaction of charge and field. after these analyses, it was pointed out that the pulse radiation is due to the suddenly occurred time - varying electrical field ( displacement current ) in the open space. this view was further evidenced by two examples : one is the partly resistance loaded antenna, the other is the partly curved antenna. the radiation procedures of the pulse electromagnetic waves of many different situations were simulated throughout this paper with the contours and waveforms of electric field given. these figures are very helpful to the understanding of the radiation mechanism of the pulse electromagnetic waves
