早在1984年, rossignac和requicha就提出用滾球法進行過渡曲面的設計,但用這種方法得到的曲面表達式比較復雜,而且在滾球半徑較大時容易出現自交的現象。Because of the continuity of the material, the elasticity property must be continuous in the transition area. here we name the transition area as transition core and assume the stiffness varying linearly with the radius
由於板材料的連續性,這個過渡區域必然是連續的,在這里,我們將這個過渡區域稱為過渡核,並且,假設過渡區域的折算剛度是按半徑線性規律變化的。Cu2 +. cr3 + were selected with different weight ratio doping in tio2 to study the photocatalyst modifying in this paper. the experiments of degradation methylene blue showed that the doping results were quantitatively correlated with the transition metal ion radii. their electronic configuration
對次甲基藍的降解實驗表明摻雜離子的修飾效果與過渡金屬離子的離子半徑、外圍電子構型、氧化還原電位和離子濃度等因素有關,質量比為0 . 5的fe ~ ( 3 + )摻雜對次甲基藍的降解效率最高。By means of curvature estimation of vertices, arc identification and arc grouping, a set of profile curves are computed to describe a rounding feature. meanwhile, a rounding mesh is extracted from the mesh model. ( 2 ) approaches of feature - based local modification on shell meshes are studied
提出了一種等半徑及變半徑圓角過渡特徵的提取演算法,採用二次曲面擬合估算出網格頂點的主曲率,根據網格過渡區域的曲率特性,計算出一系列截面輪廓線來描述圓角過渡特徵,同時將過渡區域數據從模型中分離。Second, the mode fields of a strip waveguide and some slab waveguides have been simulated by applying finite - difference time - domain ( fdtd ) method. the curvature radius ; vicinity coupling ; transition loss and power attenuation of a s - shape bend waveguide have been analysed numerically by employing wide angle finite - difference beam propagation method ( fd - bpm ), as well as the coupling loss of optical fiber and waveguide. in addition, the framework of the s - shape waveguide laser has been
其次,應用時域有限差分法,結合波導模式理論對條形與平面波導進行了模場模擬;應用廣角有限差分光束傳播法,對s形彎曲波導的曲率半徑、鄰近耦合、過渡損耗、功率衰減以及波導與光纖的各種耦合損耗進行了數值分析,並在此基礎上,對s形波導激光器的結構作了初步設計。After direct manipulation of radius, constant or variable radius area in mesh model can be modified quickly and exactly. using this method, rounding shape of a part or die can be directly modified on shell meshes for finite element analysis. ( 3 ) data segmentation on shell meshes is studied
對于已有的圓角過渡區域網格,根據圓角過渡特徵與基網格面的相切關系以及給定的新的圓角半徑,計算出輪廓線上各頂點對應的坐標,直接修改頂點的坐標值,保留網格模型原有的拓撲結構,使形成的新的網格與原有網格融為一體。The paper analyses affecting on - movement law of special cam that by transition arc radius of special cam, we conclude that transition arc radius should be great than half of groove ' s width and that sharp - angled transition will bring excessive removal while nc - machining
摘要對空間凸輪的過渡圓弧的半徑大小對凸輪運動規律的影響進行了分析,得出過渡圓弧半徑應大於槽寬的一半,尖角過渡數控加工時會產生過切現象。With the calculation result we can find that the inhomogeneous takes much less effects on the result with small core - radius ratio than that with great core - radius ratio and the small core - radius ratio ' s effect can be ignored, thus the calculation is same as homogeneous plate. the plate with great core - radius ratio should be calculated referenced the means given in this thesis
計算結果表明,在過渡區域很小的情況下,不均勻性對圓板計算結果的影響也很小,基本上可以忽略不計,按照均勻圓板計算;當過渡區域和半徑相比較大的情況下,不均勻性對計算結果的影響變得非常明顯,此時,工程上的設計計算應該參考本文提出的方法進行。分享友人
