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

論述了林學、森林與林業近兩個多世紀以來的發展和變化.林學經歷了由傳統林學向現代林學的轉變.現代林學是以森林生態系統的營建、經營管理和利用為研究對象，以發揮森林生態系統的生態環境功能為核心，全面發揮森林的多種效益和多種功能為目的的學科.對森林的認識也經歷了由單株樹木到樹木群體到森林生態系統的變化.由於對林學及森林認識的深刻變化，人們對林業的認識也就從長期形成的以木材利用為中心，轉變到以發揮森林生態系統的生態環境作用為核心和重點，全面發揮森林的生態、經濟和社會功能作為林業的指導思想和目標，以實現林業的可持續發展
