The moment that sensors detect a hairline crack anywhere in the aircraft, microscopic nano-capsules containing a high-tech adhesive would be released to seal the fissure.
当传感器检测到飞机在任何时候的一个裂痕时，包含高科技粘合剂的微观纳米胶囊将释放粘合裂痕。

The causes of crack for cold-working die are analyzed by checking machining technique and observing the microscopic structure, the technical measures to prevent cracks are put forwarded in the paper.
Then, combining with microscopic observation of rock specimen sections under compressive loads, the phenomena of stress crack and the dynamic branch have been analysed and discussed.
