“straightness measurement”造句，怎麼用straightness measurement造句

At present, long optical flat is still mainly adopted as calibrating benchmark in straightness measurement, whose accuracy is not so high (especially in measuring great-size parts).

The optical properties of doubling the measurement accuracy using the cube-corner retroreflector which is applied to laser straightness measurement are analyzed in theory.

The effects on straightness measurement are analyzed for the cube-corner retroreflector with angle errors, surface errors, yaw, pitch and roll.
