求翻译：必须指出，虽然汽车覆盖件检具在大批量生产中具有一定优势，但由于该类检具大多形状复杂、体积庞大、制作周期长、成本较高，且检测对象单一，检测柔性差，此外，检具的工作特点决定了其难以迅速获取大量精确的实测数据，并据此监控生产线的运行状况，因此进入九十年代后，随着更先进的自动化检测技术在汽车工业的广泛应用，检具已逐渐失去在覆盖件和车身在线检测中的主导地位，尤其对于大型焊接总成和车身的检测，在现代化汽车制造厂中已很少应用大型检具了。是什么意思？

It must be pointed out that the automobile cover submit has certain advantages in mass production, but check the class with mostly complex shape, bulky, long production cycles, higher costs, and the detected object is a single detection of poor flexibility, in addition, fixture characteristics deter

It must be noted that, while Motor Vehicle coverage is retrieved in the mass production has a definite advantage, but because of the prosecution and most complex shape, large, and production cycle, at a higher cost, and detect objects detected a single, flexible, and in addition, most of the charact
