The resistance is halved if the cross - sectional area is doubled. 如果截面积增加一倍,则电阻减少一半. 辞典例句 Bus bars shall be of the same cross - sectional area throughout the switchgear. 整个开关柜的母线截面均应相同. 互联网 The resistance of a conductor varies directly with its length,...
aEFFECT OF CROSS-SECTIONAL AREA. The relation between the change in cross-sectional area, velocity, and Mach number is useful in correlating the various cases of nozzle flow. Substitution of p from Eq. (6.25) into the continuity equation (6.2) gives 断面的作用。 联系在断面上的变化,速度和马...

Cross-sectional area of a cylinder A cylinder is a solid created by extending a circle through space perpendicular to its diameter. The area of a circle is given by the formula πr2, where r is the radius. It therefore makes sense that the volume of a cylinder would use the area of ...
结果1 题目 The axial force, cross-sectional area and length of the two rods are all the same, but the material is different, so the stress on the cross-section of the two rods is the same and the strain is different. 相关知识点: 试题来源: 解析 正确 反馈 收藏 ...
A cross-sectional area evaluation method for multi-cell type natural fibres treated in a highly concentrated alkali solution was proposed using kenaf fibres. Cross-section of kenaf fibres was drastically changed by the alkali treatment compared to the untreated fibres. Conventional data-based approximati...
This study investigated the cross sectional area (CSA) and fat infiltration of the epaxial muscles in Dachshunds with compressive spinal cord lesions due to intervertebral disc herniation (IVDH) and in dogs with non-compressive spinal cord lesions with fibrocartilaginous embolism (FCE). The CSA an...
