中部為燈把手，為圓柱形，上浮雕三葉，中束腰，下飾以勾連雲紋，上下對照，極富韻律感。First, based on phased array antenna ' s mono - pulse goniometry and separate coordinate technology about phase control, the antenna beam pointing error formula, caused by phase quantization error, is derived from linear array and circular array to planar array and cylindrical array
首先以單脈沖相控陣天線測角原理為基本理論出發點，利用相位控制的坐標分離技術，基於線陣、圓形陣等簡單形式的相控陣天線，推導了平面陣、圓柱面陣等相控陣天線由相位量化誤差引起的波束指向誤差公式。In 1990s, a calculation of the ground - state energy of an exciton confined in a cylindrical quantum wire in the presence of a uniform magnetic field is reported as a function of wire radius, using a variational approach by gang li, spiros v. branis and k. k. bajaj. a. balandin and s. bandyopadhya present variational calculations of the ground - state exciton binding energy and exciton radius in a quantum wire subjected to an external magnetic field. these studies have been primarily responsible for our current understanding of the nature of excitonic states in a quantum wire subjected to an external magnetic field
九十年代中期，人們就開始了關于在外加磁場時量子線中激子特性的研究， gangli ， spirosv . branis和k . k . bajaj利用變分法，對于圓柱形的量子線中激子的基態束縛能進行了計算，發現對於一個給定的磁場值，激子的基態束縛能比不加磁場時變大。The three - dimension dbf of circular array and cylinder array are presented. we adopt equivalent with uniformity linear array ( ula ) in cylinder beam forming, and compare pattern of directional elements with of omni - directional elements
在圓柱陣的波束形成模擬中，採用了等效均勻線陣的方法，簡化了數字波束形成的計算量，並且還對有向陣元和全向陣元在陣列波束形成中的影響進行了模擬比較。分享友人
