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布或速度分布條件下,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;其不足之處在于,對設計者而言,很難給定理想的葉片表面壓力分布或速度分布,并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。

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 其次,為全面了解這種新型電磁電機的電磁特性和動力特性,本文從電機磁場的基本方程及其邊界條件出發,應用無旋磁場的標量磁位概念,建立了端面搖擺式電磁微電機內部磁場的數學模型,并以此為基礎,詳細分析了電機氣隙磁場的各方面性質,對氣隙磁場的磁標位、磁場強度、磁感應強度、等磁位面形狀、電機工作磁路的分布、電機的工作磁通量以及激勵繞組的自感和相互之間的互感進行了詳細的分析計算。

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。
