( 2 ) the bending angle is varied along scanning direction, and there is a deformation wave in the process. ( 3 ) the effects of sheet length on bending can be neglected while the length is more than 10 times of thickness. ( 4 ) the sheet width has much higher influence on the bending process
分析發現：激光彎曲成形時板料的應力狀態與機械折彎時有根本不同；當激光束沿直線單向掃描時，板料兩端的彎曲角度不同；板料的長度大於10倍板厚或5倍光斑尺寸時，板長對彎曲角度的影響不再顯著；沿掃描方向，距離光斑中心3倍光斑尺寸以外的區域，仍然對彎曲變形量產生影響。Considering that : ( 1 ) radar can achieve its basic application of collision avoidance and warning with the only function of ranging ; ( 2 ) under high speed conditions, radar should have lager effective range than that under slow speed, we designed a new easily realizable automotive anticollision radar, which employs centimeter wave and square pulse amplitude modulation
考慮到： （ 1 ）核心的測距功能實現以後，雷達已經能夠完成基本的防撞預警； （ 2 ）在汽車高速運行的情況下，防撞雷達的最小可測距范圍和最大作用距離應比低速狀態下大。本文採用了技術成熟，易於工程實現的厘米波脈沖雷達，以單波束輻射的方式測距。The simulation results show that to start the oscillation, the length of the resonance cavity must be well matched with the radial span of the cavity ; mismatch of them will greatly affect the microwave development ; the output power of the microwave in rtto is affected by the microwave mode obviously. under the same conditions, the output power for temooi mode is the highest, and its start and saturation time of oscillation are the shortest. the results also show that the output power will decrease with the increase of the size of the extract window ; the operating state of rtto has great close relationship with the operating current, and there exists an optimum current value
結果表明，束電壓一定時，諧振腔腔長和徑向間距必須良好匹配微波才能起振，匹配不佳會極大地影響微波產生；微波模式對微波產生功率影響很大，同等條件下， tem _ （ 001 ）模式的微波功率最高，起振時間和飽和時間最短；微波輸出功率隨提取口的增大而減小； rtto工作狀態與工作電流的大小關系密切，存在一個最佳工作電流值。Chapter 3 : we find a family of solutions of the paraxial wave equation that represents ultrashort pulsed light beams propagation in free space. these pulsed beams have an arbitrary temporal form and a nearly elegant hermite - gaussian cross section, which pulsed beams we call the ultralshort pulsed elegant hermite - gaussian beams
此脈沖光束解的每個頻率分量都是eleganthermite - gaussain光束，時間脈沖的形狀是任意的，具有相同的衍射距離參數，並且可以描述短於一個光學周期的超短脈沖。The interaction mechanism of atomic force between tip and sample was unveiled more clearly with the analysis of the change regularity of force - distance curve. the theoretical research about the light pressure of laser and the gravity exerting on the micro - cantilever was first conducted in this paper : setting up the interacting model and formula of the light pressure, investigating the effects of these factors on the interaction mechanism of atomic force and the performance of afm, conceiving a method to remove these effects and so on. all of these were the theoretical foundation of developing the new atomic force microscopy and the new type of horizontal afm system
本文在全面分析掃描探針顯微鏡（ spm ）技術，特別是afm技術的國內外發展歷史、現狀及存在的主要問題的基礎上，進一步揭示了afm的原子力作用機理，著重分析了力?距離曲線的變化規律；對作用在微懸臂上的光壓力和微懸臂本身的重力進行了系統的理論研究和計算分析，建立了激光束對afm微懸臂的光壓作用模型及計算公式，考察了這些因素對原子力作用機理及afm性能的影響；提出克服或消除這些影響的理論構想，為發展新的afm技術、研製新型afm系統提供了重要的理論依據。分享友人
