自旋—自旋相互作用对红宝石基态零场分裂的贡献
2007/12/13
在弱场(LГ表象)中,考虑了d3组态内自旋-自旋相互作用对红宝石基态零场分裂的影响。结果表明它对零场分裂的贡献为0.12厘米-1。
周期场透镜的成象特性
2007/12/13
由三个或五个透镜元素组成的周期场,可以作为离子透镜使离子束成象。通常它具有比单个透镜元素强得多的聚焦能力(在相同的电压比下)。这种周期场透镜曾用于静电加速器离子源初聚系统中,但它的成象特性尚未有详细的分析。本文提出一种研究这类透镜特性的方法。将周期场看作由若干个透镜元素合成的组合透镜,然后以Ferraris特征行列式求它的基点表示式。作为普遍情况,以浸没透镜作为透镜元素,导得了三个和五个透镜元素的...
威士氏场论之讨论
2007/12/12
对於一曲面上之施落亭格波函数在曲面变化时所发生之变化,威士氏有一理论。今将其理论补充,使其完整,使此理论,在场之兰格伦日包含场量之各种微分时,依然可用。所获得之方程式之可积分性,用与其相当之哈密尔顿—雅科俾方程式之可积分性证明之。此种讨论,同时证明各种变数中之对换关系在罗兰丝变化下之不变性。
最小摩阻场
2007/12/12
前文简略地提到塑压陡线规律。本文视最小摩阻条件所定义之塑压接触面为一曲面“流”场,旨在于提出此“最小摩阻场”之场线规律与场函数(摩擦应力τ,压应力p)规律。主要结果为:推广前文之陡线规律于广泛情况,指出“摩擦场”与“滑质场”之基本区别在于前者为发散场,向外减阻;后者为收敛场,向内减阻。二者之复合场有“分水岭”,内场收敛,外场发散。金属表面之粘性粘着区须为一收敛场。陡线规律之库仑标量方程引出两重要推...
