Mean hemispherical intensity
平均半球面發光強度The two sunspots of a pair have different polarities, one would be a magnetic north and the other is a magnetic south. thus, we believe that there are magnetic field lines joining the two sunspots of a pair. the strong magnetic field locks the gas of the photosphere in places and inhibits the hotter gas below to rise at the sunspots
黑子經常成雙成對出現,每對皆由極性相反的黑子組成,若一個為磁北,另一個必為磁南,由此我們估計每對黑子皆由磁力線所連系,強大的磁場牽制著光球層上的氣體,並阻止了下層較熾熱的氣體上升至黑子范圍,結果黑子比太陽表面其他地方溫度較低。The relation between stellar chromospheric activity and rotation of evolution stars have a good relativity. but meticulous analysis show chromospheric activity of evolution stars depend on stellar spectral type and effective temperature strongly. we provide several possible explain for those phenomena
但是細致分析顯示演化恆星色球活動水平隨恆星自轉周期間的分佈對恆星光譜型和恆星表面有效溫度有很強的依賴,並對這些現象提出了幾種可能的解釋。Abstract : it is observed that the sommerfeld ' s formula for a progressive spherical wave is not covariant with respectro the rotation of the coordinate system. it contains complex partial waves that are not physical. the standing wave representation of the same formula is shown to be covariant and physical. it is applied to solve the boundary value problem of fiber optics. the radiation modes as well as the guided normal modes are obtained in closed forms. the intensity distribution in various modes is obtained. it is remarked that the mode of critical refraction is missing
文摘:說明了球面行波的索末菲公式在坐標轉動下不協變.證明了球面波的駐波表示是協變的,因而是一個物理的關系式,故適用於圓柱坐標中各類波動方程的定解問題.作為一個例,應用於光纖光學,導出了受導簡正模和輻射模的表達式,以及各模式的強度分佈The simulation program has been implemented to simulate the procedure of hxmt detecting x - ray source. the simulation result has been used to analyze the overlay region in celestial sphere, the variation of photon current intensity and the variation of the angle between sun and orbit, which demonstrate the reason why to select a 550 km height and 43o inclination low earth orbit as hxmt ' s orbit
利用模擬程序,實現了模擬一個正在預研的天文衛星? ?硬x射線調制望遠鏡hxmt觀測x射線源的過程,分析了天球覆蓋、 hxmt接收的光子流強度的變化和太陽軌道面夾角的變化,說明了選取高度為550km ,傾角43o的近地圓軌道作為hxmt的運行軌道是合理的選擇。According to the traditional rytov method, the theory model of modified rytov method is given for plane wave and spherical wave propagation in the atmospheric turbulence, and the characters of optical scintillation for waves propagation along horizontal paths is studied, the inner scale effect is considered, especially. then, the results, calculated by the modified rytov method, is compared with the experiment measurement, it shows that the modified method is suitable in moderate atmospheric turbulence
本文介紹了光波在湍流大氣中傳播的弱起伏和強起伏理論,從經典弱起伏理論出發,給出了光波在水平傳輸時的修正rytov方法理論模型,分析了在考慮湍流內尺度的影響下平面波和球面波入射時的閃爍特性,在中等湍流區計算結果與最近實驗結果符合得較好。Aiming at the requirement of aspheric optical parts and the present state of their testing, it will have an important practical value to develop an equipment that will be easy to operate, commonly used and will have high testing precision
