阿基米德螺旋 meaning in Chinese
archimedean screw
archimedes screw
archimedes' screw
Examples
- Archimedean screw pump
阿基米德螺旋泵 - What is new is the application , which by an inversion of the energy flow in its operation , turns the archimedes screw trough pump into a power generator for the extraction of energy
水力螺旋发电机的独到之处在于对水流能量进行逆向利用，把阿基米德螺旋泵转变成一个可以从水流中提取能量的发电机。 - In this thesis , the concept of " fractal " and the recursive algorithm of fractal structure are depicted . the wavelength - independent character of archimedean spiral antenna and the space filled property of koch monopole are analyzed by the method of moment
本文介绍了分形的基本概念和分形结构的迭代算法，采用矩量法分析了阿基米德螺旋天线的频率无关特性和koch单极天线的空间填充特性。 - Since complicated differential and integral operations were involved in the kernel of the integral equation , we simplified the equation and got the nakano equation . as instances , the planar archimedean spiral antenna , the planar equiangular spiral antenna , the monofilar helical antenna , the conical helical antenna with fixed ascending angle and the conical equiangular - spiral antenna were analyzed through the moment method . all of the results matched fairly well with the references and experiment results
这种方法的积分方程的积分核里含有复杂的微积分运算，为了简化计算，本文在推广的海伦积分方程的基础上，对方程进行了简化，推导了nakano方程，并以平面阿基米德螺旋天线，平面等角螺旋天线，轴向模圆柱螺旋天线，具有固定升角的圆锥螺旋天线和圆锥等角螺旋天线为例，用矩量法求解了天线上的电流分布，研究了螺旋天线辐射的宽频带特性，所得的结果均与参考文献吻合很好。
