In this paper, we discuss a class of integrodifferential equations in transport theory, which is the neutron transport equations for a cylinder of in - finite height under assumptions of continuous energy. 本文讨论了以迁移理论为背景的一类积分-微分型方程,即非均匀介质中具连续能量的无限高圆柱模型的中子迁移方程的求解问题。
Effect of Stuffing Rate on the Band Gap Structure of the Finite Height(FH) Photonic Crystals 填充率对有限高度(FH)二维光子晶体带隙的影响
Application of the Finite Element Method Approximating Abnormal Height Curved Surface 有限元法逼近高程异常曲面的应用研究
The influence of each material size on the reliability was determined by Finite Element Analysis. And the height of Cu affects the maximum stress most. 通过有限元分析确定了各个材料尺寸对最大应力的影响,发现铜柱的高度对最大应力影响最大。
The transducer is designed through theory, but acoustic field generated by transducer with concave spherical surface is unknown, so it is taken that the finite element parametric thoughts to design height and radius of concave spherical surface. 由于换能器发射端为凹球面,产生的声场分布未知,所以采用有限元参数化思想,设计换能器的凹球面半径与凹陷高度。
