Then from the equations of the matrix elements the equation of the usual two composite boson is separated, as it is a three-dimensionalequation, the ghost states disappear.
而后由矩阵元方程分离出通常两个复合玻色粒子满足的等时方程，它是一个三维方程，因此无鬼态。

The equation smoothes out the irregularities of an object, transforming it mathematically into something that looks like a uniform three-dimensional sphere.
这个方程能消除物体间的差异，并能把物件精确的变形为一个统一的三维球体。

Dr Perelman proved Poincaré's conjecture by taking an equation normally used to model heat dissipation in three-dimensional objects, known as Ricci flow.
