  1. We propose a novel controllable atomic beam - spiller based on the uccc and discuss the splitting mechanism of the guided atomic beam in the beam splitter from two aspects of the magnetic - field distribution and the trace of the guiding centers. the splitting ratio of the beam splitter can be adjusted by adding a homogeneous bias magnetic field along the y - direction, and the relationship between the splitting ratio and the additional bias field is analyzed

    本文提出了一種採用在y方向上加一偏置磁場來實現分束比可控的新穎原子分束器，並從磁場分佈和導引中心軌跡兩個方面，詳細分析和討論了基於u -型載流導體所構建的原子分束器的分束機制。
  2. Optimal decay rate of a homogeneous euler - bernoulli beam with boundary control

    梁邊界控制的最優衰減率
  3. A device for converting heterogeneous beam of radiation ( elec tromagnetic or particulate ) to homogeneous beam by absorption or refraction of unwanted components

    利用吸收或折射掉不需要的成分，把非單色光束（電磁的或粒子的）變成單色光束的裝置。
  4. The main work done in this dissertation is organized as follows : in chapter 1, we consider a vibrating non - homogeneous beam with one segment made of viscoelastic material of kelvin - voigt type, and other parts made of elastic material by means of timoshenko model

    當梁的橫截面的尺寸與其長度相比不能忽略時，需要考慮轉動慣量的影響，此時梁的模型由rayleigh梁給出。進一步，如果再考慮到由剪切力引起的偏差，就需要引入timoshenko梁的模型。
  5. Taking structural intensity as cost function, we study the active control of infinite beam and non - homogeneous beam and present the result of active control under the condition of different location of error sensors and different distance between control force and primary force in the beam

    以結構聲強為目標函數，對無限長梁和非齊次邊界梁進行主動控制研究，給出了不同的誤差傳感器位置、不同的初級力和控制力之間的位置關系對主動控制效果的影響。
  6. The distance from figure center of the parabola to the potential slide surface is less than half of the section length. mechanical conditions of this method include not only force equilibrium but also moment equilibrium. as for the beam - on - foundation, its pressure can be calculated by homogeneous hypothesis or winkler foundation hypothesis or infinite half elastic foundation hypothesis on the pulling anchor - cable step and by coulomb active earth pressure theory approximatively on the long term working step

    對于樁在滑面以上段所受的坡體荷載，提出可按形心偏下的拋物線型分佈模式計算，並在滿足力的平衡條件的同時還滿足力矩平衡條件；對于地樑上作用的坡體荷載，提出在錨索張拉階段可按均布或溫克爾（ winkler ）地基假定或彈性半無限體地基假定來計算，在工作階段則一般可以近似按庫侖主動土壓力理論計算。
