By using the principle of X ray stress measurement, the bearing stress factors of matrix in composites was measured.
结合X射线应力测量原理，建立出基体承载系数的X射线应力测量方法。

The accuracy of the electric energy measurement device has direct bearing on the economic benefit of each enterprise within the electric power system.
电能计量装置准确与否，直接关系到电力系统中各企业的经济效益。
