点对称 meaning in English
[数学] point symmetry
Examples
- It has one critical fixed point 0 and two symmetric critical points ? under this parameterization
在这个参数表示下， 0为临界不动点；另外两个关于0点对称的临界点为士c 。 - In the course of testing , some static data , such as deflection , strain and cracks of every load step are recorded
静力试验采用两点对称加载方案,分级加载,记录试验梁的挠度、应变、裂缝分布特征。 - When a solid regionin three - space is symmetric with respect to a point , the evaluation of triple integrals over is often facilitated by using spherical coordinates
当空间立体区域关于某个点对称时,计算上的三重积分通常使用球坐标比较容易。 - An integral property and its physical significance of difinite integral , double & triple integral , curve and curved surface integral of generalized odd and even functions are demonstrated , which are symmetrical about plane , line and point in the domain
论述了关于面、线、点对称的区域上的广义奇、偶函数的定积分、二重、三重积分、曲线、曲面积分的一个性质及其物理意义。 - The prime works are as follows : strain and stress distribution of section was analyzed . the effect of prestress degree . on cracking moment was explored . the relation of the unbonded prestress increment to effective reinforcement index and corresponding bonded prestress increment were studied . the formulae had been established
