研究人员用这些照片来测量老虎脚印的长度和宽度以及脚趾之间的角度,以及10种其他变量来确定不同老虎的“身份”。
The entire device is 300 micrometres thick – about the width of three human hairs – and withstood tests in which it was bent to a 90-degree angle 700, 000 times.整个设备300微米厚,大约只有三倍头发丝的厚度,可以经受90度的弯曲70万次。
The results showed that there were distinct differences in micro-fibril Angle, width of growth-ring and tracheid diameter.结果表明,管胞直径和微纤丝角及生长轮宽度等指标表现为差异显著。
