Besides that, we presents the gravitational wave energy density under the weak field situation and gives the x - y plane numerical calculation to curvature scalar R and energy density .
还有计算了在弱场条件近似下引力驻波的能量密度,并给出曲率标量R和能量密度平面的数值计算。

By controling the three-dimensional motion of the X-Y table and bond head, precision positioning and desired line-type gold wires can be realized, and an ultrasonic wave bonded method is used.
