  1. 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
  2. The theoretical study on business cycle has become an attracting academic area, since the phenomena of business cycle was found by economists. after that, a great many economists have put forward all sorts of theoretical explanations of the reason that leads to the business cycle. although there is n ' t yet a perfect explanation that can accounts for the business cycle completely and exactly, all the economic cycle theories are precious wealth that can help people understand and even to some extent control the business cycle

    自經濟學家發現經濟周期以來，該領域的理論研究就成為了一門引人入勝的學科，在不同時期、不同國家中，眾多的經濟學家都對經濟周期產生的原因提出了多種多樣的理論解釋，雖然還沒有出現能全面而準確地解釋經濟周期的理論，但眾多的經濟周期理論確實給人們了解和把握經濟周期提供了不可或缺的寶貴財富。
  3. ( 3 ) in the new theory of synthetic conceptual design of torpedo, this paper takes operational effectiveness as the object function in the optimization model. models and analysis methods are given for the synthetic conceptual design of torpedo based on the operational effectiveness. in order to involve economic index in the study, this paper introduces life circle cost into the synthetic conceptual design, and gives a model of design based on the ratio of cost and effectiveness
