-
Aberration of electronic lens made by electron gun and aberration of magnetic deflection system made by dy are comprehensively investigated, so is the shadow mask ' s effect on electron beam landing screen error. the conclusion can be get that, because the distribution of electron beam landing screen ( distribution of luminance ) is affected by many kinds of factors, it cannot get the correct function by calculation, and should be get by measurement instead
全面分析了cpt電子槍發射系統形成的電子透鏡像差與磁偏轉系統形成的偏轉像差；分析了蔭罩的自身厚度與位移對電子束著屏的影響，並由此得出結論，著屏電子束分佈（即亮度分佈）受著許多因素的影響，理論分析是半定量的，著屏電子束分佈需要用精確的測量儀器來測量。 -
A sensing magnetic field and displacement type of giant magneostrictive microdisplacement actuator with the functional of sensing driving magnetic field and microdisplacement is developed, and the design theories and approaches being applicable this type of microdisplacement actuator are pointed out : a circular diaphragm type of flexible construction that acts as integration mechanism of microdisplacement transferring and sensing of giant magnetostrictive microdisplacement actuator is adopted, sheet flexure theory of elasticity mechanics and approach of finite element are applied to design and calculate it, corresponding deflection and analytic formula and distribution curve of stress are given, and the specific achieving approaches of measuring principle and magnetic field sensing function of driving field in giant magnetostricitive rod are pointed out the magnetic field sensing function of the actuator is used to practically measure driving magnetic field of actuator and to obtain the relationship of driving magnetic field and coil current, which is also analyzed and studied

Solar wind flows out from the corona the sun s outer atmosphere into interplanetary space at speed of between 300 and 900 km per second. it causes fluctuation to the earth s magnetic field, which we call magnetic storm. such event will cause deflection of compass needles
而太陽風則以每秒300至900千米的速度由日冕太陽外大氣層向外拋射，進入行星際空間，對地球磁場造成擾動而產生磁暴，導致指南針指針偏移，嚴重的話更會導致電力受阻和電話線路中斷。 -
Magnetic actuation has been an excellent candidate for applications that require large deflection of actuators because of the well - known advantages over electrostatic, thermal, or piezoelectric actuation methods
再次，磁力驅動的控制方法比靜電驅動、熱驅動、壓電驅動簡單得多，而且對于要求實現大撓度的應用來說，是最為理想的驅動方式。
