Many planets ( for example, ganymede, mercury, the earth, jupiter and saturn ) and stars ( for example, the sun ) possess intrinsic magnetic fields. the explanation for their existence and variation remains a great challenge to planetary scientists and astrophysicists. this article attempts to review some recent developments and difficulties in the study of magnetohydrodynamics for the electrically conducting fluid interiors of planets and stars. it is the fluid motions, usually driven by thermal convection, that generate and sustain magnetic fields through magnetohydrodynamic processes in planets and stars. in planets, the magnetohydrodynamic processes are strongly affected by the combined and inseparable effects of rotation, magnetic fields and spherical geometry. the key dynamics involves the interaction between the coriolis and lorentz forces. in the sun, it is the solar tachocline, a thin shear flow layer located at the base of the convection envelope, that plays an essential role in the solar magnetohydrodynamic processes which produce the 11 - year sunspot cycle. some results of a new nonlinear three - dimensional solar dynamo model are also presented
許多行星(如木衛三,水星,地球,木星和土星)和恆星(如太陽)具有內部磁場.對這些磁場的存在和變化的解釋對行星科學家和天體物理學家是一個巨大的挑戰.本文試圖總結行星和恆星的導電流體內部磁流體力學研究的新近發展和困難.一般由熱對流驅動的流動通過磁流體力學過程產生並維持在行星和恆星中的磁場.在行星中磁流體力學過程強烈地受到轉動,磁場和球幾何位型的綜合影響.其動力學的關鍵方面涉及科里奧利力和洛倫茲力間的相互作用.在太陽中其流線,即處于對流層的薄的剪切流層在太陽的磁流體力學過程中扮演了一個基本的角色,並由之產生了11年的太陽黑子周期.本文也給出了一個新的非線性三維太陽發電機模型Between chromospheric activity index and corona activity index of ms stars, there exist good linear relativity. but for evolution stars, this relation show a large dispersion
我們發現主序星的色球與冕球磁活動指數存在著很好的線性相關性,而演化恆星的則表現出較弱的相關性。From the distribution of rotation period and convection parameter of m type stars, stellar chromospheric activity of m type stars depart from the anticipation of a. dynamo theory obviously
從m型主序星的自轉周期的和恆星內部對流區隨色指數的分佈來看, m型主序星的色球活動行為與發電機理論的預期有明顯的差異。By the reserching the relation between stellar chromospheric activity and color index, we find that stellar ages play a pivotal role for producing vaughan - preston gap of ms stars
通過主序星的色球活動對恆星色指數不同依賴關系的研究,我們分析了vaughan ? preston間隙產生的原因,分析結果顯示恆星的年齡在這一間隙的形成中扮演了重要的角色。Furthermore, we also reserch the influence of setllar age to stellar activity of late - type stars. the relation of stellar chromospheric activity and rotation of late - type main sequence stars depend on stellar spectral type
大樣本分析顯示晚型主序恆星的色球活動與恆星自轉參量的研究晚型主序恆星的色球活動與恆星自轉參量間的關系表現出對恆星光譜型的依賴。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。Though this departure is not obvious, the result still support the conclusion in the analysis of stellar chromospheric activity. for evolution stars, wo do n ' t, obtain significative result because the deficient samples. but the statistics analysis show the distrbution of corona activity of late type with color index and rotation period exist upper limit
演化恆星的磁冕球活動在色指數和自轉周期的分佈上都顯示出冕球磁活動存在上限的現象,並且對冕球磁活動上限的擬合表明在色指數b一v為1 . 0附近和自轉周期For a - early f type ms stars, stellar chromospheric activity decrease with stellar rotation period, but increase with rossby number ; for m type ms stars, stellar chromospheric activity increase with stellar rotation period and rossby number, and stellar chromospheric activity reach saturation at large color index ; for the ms stars between mid - f to m type, stellar chromospheric activity decrease with stellar rotation period and rossby number
A ?早f型主序恆星的自轉周期和恆星對流區的隨色指數的分佈明顯地影響著這些恆星的色球活動行為。而m型主序星的色球活動水平基本上隨自轉參量的增大呈上升趨勢,並且m型主序星的色球活動水平在色指數較大時趨于飽和。We have collected a mass of stellar activity and rotation data of late - type stars. combining with the results of hipparcos satellite, we reserch the relation between stellar activity and rotation ( include rotation period and rossby number ), and discuss the distribution of stellar rotation period and the evolution of angle momentum of late - type stars
因此,我們收集了晚型恆星的色球和冕球活動的指數以及恆星自轉方面研究發表的大量的觀測資料並結合hipparcos衛星的觀測結果,對晚型恆星的磁活動與恆星自轉間的相關性進行細致的研究。This phenomenon farther surport our conclusion in the analysis of evolution stars, i. e. the difference of stellar chromosphere and corona activity of evolution stars is bred by the energy balance and heating mechanism in stellar chromosphere and corona
M型主序星在演化恆星的冕球活動與色球活動行為的差異則是由於m型主序星的色球與冕球間存在的能量平衡和轉移過程產生的。The us stock market plunge on monday, 19 october 1987 sparked off a worldwide stock market slide. in hong kong, panic sale of stocks plummeted the hang seng index by 420 points, or 11 per cent in one trading day
美股於一九八七年十月十九日急跌,引發全球股市大幅下滑,港股出現恐慌性拋售,恆生指數於一夜間下跌四百二十點,跌幅達百分之十一,被稱為黑色星期一。分享友人
