  1. The results showed that the processing parameters ( such as laser power, the diameter of laser, scanning speed of laser beam, ratio of overlapping ) are important to acquire a perfect component. furthermore, in order to assure geometric properties ( accuracy, surface finish ), the structure of the off - axial powder nozzle was improved to avoid the oxidation of the molten pool. the density metal test sample of rene95 high - temperature alloy was made by lsf through optimizing the processing parameters

    本文對激光立體成形的工藝特性進行了深入系統的研究，發現如果要獲得理想的成形效果，就必須對成形過程中的工藝參數進行精密控制，例如激光功率、激光光斑大小、光束掃描速度、搭接率等；同時為了保證成形件有較高的尺寸精度和表面質量，必須對成形零件的氧化問題進行控制，通過改進側向送粉噴嘴的結構設計，成形件的表面氧化問題得到適度控制。
  2. The main factors influencing power saving of the beam pumping unit with high slip motor are pumping speed of the unit, slip ratio of the motor and rotary inertia of rotating parts

    指出影響使用高轉差率電動機的游梁式抽油機節能的主要因素是抽油機的沖次、電動機轉差率和旋轉件的轉動慣量。
  3. ( 2 ) if not considering blind space and targets are uniformly distributed, detectionperformance are close for the three kinds of line when speed - ratio is less than 1, and cross - toline will achieve higher enter - cover - probability when speed - ratio is more than 1. if takingblind space into account, for case of balance - beam radar, cross - away line can get higherstrict - enter - cover - probability. but for fear that probablely - enter - cover target distribution comesbehind the patrol line, the three factors should be limited if taking cross line

    若考慮盲區的影響，對平衡木構型的雷達而言，交叉同向航線的嚴格覆蓋率較大;但為了使區域縱深不反向至我方空域，採用交叉航線時航線橫比、航線縱比、速度比的取值范圍要受到限制，否則雷達動態性能將大打折扣。
