  1. As we know, inverse techniques make blade ' s profile well compatible with its surface velocity distribution, however, they give designers big challenges that the ideal velocity distribution is hard to obtained and sometimes the non - physical solution, such as double covering of flow field or unclosed profiles, would come out. the proposed design procedure in the paper has avoided the disadvantage mentioned above. in this paper, a quasi - irrotational equation is used to describe the flow in cascade instead of the generally used irrotational equation

    眾所周知，一般的反問題和混合問題的最大特點，是在給定的壓力面和吸力面上的壓力分佈或速度分佈條件下，直接得到葉片的幾何形狀，它可以使葉型型面與表面氣流參數有機結起來；其不足之處在於，對設計者而言，很難給定理想的葉片表面壓力分佈或速度分佈，並且有時會得到一個非物理解，如：得出的初始葉型可能會出現前緣、尾緣不封閉的現象。
  2. Irrotational and solenoidal split problem on a dyadic green ' s function of the field vector

    一類場矢量的並矢格林函數無旋和無散分解問題
  3. This clearly indicates that uniqueness is reached provided that the irrotational and equivoluminal wave velocities, and are real and nonzero.

    這就清楚地表明，如果無旋波速度和等體積波速度是不等於零的實量，則唯一性是成立的。
  4. Interaction between the large cylinder and the horizontal irrotational shallow water wave with current

  6. As being superfluid, particle current in bec is irrotational and this makes that its respondence to rotation is different from rotating as a whole for usual fluid and is to form a vortex or vortex lattice

    作為超流體， bec中的粒子流是無旋的，這使得它對旋轉的響應異于普通流體的整體轉動而產生渦旋或渦旋晶格。
  7. Next, in order to comprehand the electromagnetic characteristics and the dynamic characteristics of the new type of magnetic micromotors, the dissertation applied the concept of the magnetic scarlar potential of the irrotational magnetic fields and set up the mathmatic model for the inner magnetic field of the new type of motors from the basic equations and the boundary conditions of the motor magnetic field. oh the basis of the mathmatic model, the dissertation analized the various qualities of the magnetic field of the air gap between the rotor and the stator and gave a detailed calculation of the air gap ' s magnetic potential, magnetic field intensity, magnetic induction, the shape of the magnetic scarlar potential level surface, the distribution of the magnetic circuit, the magnetic induction the self - inductance and the mutual inductance of the coils
