可保持的

Magneto-optic imaging technology is a new method of eddying measurement, which not only preserves the merit of conventional eddy current inspection, but also realizes the visual NDT of sub surface's minute defect by replacing measuring coil by laser.

磁光成像技术是涡流检测技术的一种新方法。这种方法不仅保持了传统涡流探伤方法的优点，而且用激光取代了测量线圈，实现了对亚表面细小缺陷的可视化无损检测。

The key problem of a message definition is to keep it simple, consistent, extensible and strong typed.

In comparison with the scheme of high-order SQUID gradiometer, the method is simple without introducing any extra-intrinsic noise to SQUID sensor.

与高阶梯度计方案相比，虽然当环境干扰改变时，它保持平衡的能力较低，但是这种方法不仅简单易行，而且对SQUID不引入任何附加的本征噪声，从而可大大降低建造昂贵电磁屏蔽室的费用。
