After being improved, the gear surface contact fatigue strength obeys weibull distribution and stress obeys normal distribution, the gear bottom bend fatigue strength and stress obey logarithm normal distribution, according to the relation of average safe rate and reliability, then the gear strength reliability design and check equations can be deduced
將齒面接觸疲勞強度按威布爾分佈、應力按正態分佈處理，將齒根彎曲疲勞強度和應力均按對數正態分佈處理，再根據平均安全系數和可靠度之間的關系，推導出了齒輪強度可靠性設計和校核公式。 -
The paper has improved the existing lifting - line and lifting - surface design method by including the rake and skew and solving the optimum circulation distribution with the optimum theory. the blade geometry is expressed with b - spline for the lift - surface method. the boundary condition on the blade is transformed to minimize the summation of the square of normal velocities, the fair blade geometry can be obtained by present technique and the design quality is better
改進了現有的升力線和升力面設計方法，在升力線設計中計及槳葉的縱傾和側斜的影響，用優化理論求解最佳環量分佈，升力面設計中用b樣條來擬合槳葉，將物面邊界條件轉化為求法向速度分量的平方最小，由此可得到光順的槳葉幾何形狀，提高和改進了設計質量。 -
In pulsed field magnetization condition, we find some new phenomena characteristic, that is, the trapped fluxes of ybco bulk increase with increasing intensity of applied field up to about 1. 9t, but decease beyond this value and the scanning distribution map of the trapped fluxes on the surface of the superconductor is not slick, which is different with the superconductors magnetized in constant magnetic field and the normal permanent magnets
超導體在脈沖場下具有特殊的勵磁特性，當脈沖場在1 . 9t左右時，由於在脈沖場下超導體內的磁通線運動受到較大的粘滯力作用，超導體表面中心的俘獲場分佈掃描圖將出現一些凹陷區域，這是跟超導體在恆定場下的勵磁和一般永磁體所不同的。 -
This paper contains a useful smmary of log normal distribution, weibull distribution and the k - distribution. the weibull distribution may well extend to phenomena other than radar including radiation scattered from turbulent or rough surface
