Among hese method, one of the simplest is the deepest gradient descent algorithm, but it has one disadvantage that the solutions are oscillatory and slowly convergent. a friction term is ntroduced to avoid oscillatory solutions and raise convergence rate. the third major contribution of this dissertation is study on 3 - d diffuse object surface optical automatic measurement
其次，結合要處理的具體問題，介紹數值優化及幾種常用的無約束最優化計算方法，以最優梯度法為基礎，討論其演算法的優缺點，通過引進阻尼系數，改進了演算法的收斂速度，從而提高迭代精度。 -
5. the luminescence enhancement of eu3 + was also observed after ultraviolet irradiation but was weaker than the zns : mn2 + and the branch ratio of 5d0 - 7f0 increased after irradiation. it indicates probably the contribution from the centers in the surface of nanoparticles increased
在紫外光的輻照下首次觀察到eu3 +離子發光的熒光增強現象，輻照后5d0 < wp = 5 > 7f0發射強度分支比增加，表明對稱性較低的發光中心對發光的貢獻增加，可能是處于顆粒表面的eu3 +離子對發光的貢獻增加。 -
The effect of splash erosion on sloping surface erosion is evident. after the splash erosion was eliminated, the erosion amount was less than half of the amount when the splash erosion existed. it indicated the splash erosion contributed more than 50 % erosion amount, but to the different soil type, the contribution ratio of erosion amount varied, such as the soils derived from granite, the contribution ratio reached 70 %
在有無紗網兩種處理條件下的產沙實驗表明，雨滴濺蝕對坡面土壤侵蝕量有明顯的影響，消除濺蝕作用後土壤侵蝕量不到有濺蝕作用的一半，說明濺蝕對坡面產沙的貢獻佔50以上，不同土壤類型其貢獻率不同，如結構性較差花崗巖紅壤，濺蝕貢獻率高達70 。 -
The stability, rheology, chain structure and consecutive medium model in magnetorheological fluids are analyzed. according to the contribution of shear stress and normal pressure in polishing zone, the quantificational machining model of mrp is presented. as an example of plane workpiece, the influences of machining parameters on removal rate and surface roughness in mrp are studied
5 、磁流變拋光（ mrf ）是超光滑光學表面的一種新型加工技術，本文從mrf的磁、力學性質出發，研究了磁流液的穩定性、流變效應、鏈化結構和連續介質模型；根據拋光區內剪應力、正壓力的分佈特徵，提出了mrf的定量加工模型；然後以平面工件的磁流變拋光為例，揭示了工藝參數對材料去除率和表面粗糙度的影響規律。 -
