Since scalars are independent of the coordinate system, the dot product of two vectors is called a scalar invariant . 因为标量与坐标系无关,故两个矢量的点积称为标量不变量。
In other coordinates it will involve second and possibly first derivatives with respect to time . 在别的坐标系中,它除了包含对时间的二阶微商外,还可能会包含对时间的一阶微商。
They form a three-parametric, orthogonal net and may be chosen as coordinate lines of a special, curvilinear coordinate system . 它们形成三参数正交网,可以把它们选作特殊曲线坐标系的坐标线。
