An array of tiny pieces of paraelectric material can sense the heat radiated by a person, and the pattern of the array's electrical outputs can then be used to construct an image.
一组微小的顺电材料可以感知一个人发出的热量,然后利用该阵列的电输出模式构建图像。
TEMs work by firing a beam of electrons through the material and measuring how it absorbs and deflects the particles to build up an image of the sample.
TEMs 的工作原理是通过发射一束电子穿过某种物质,并测量它如何吸收和偏转粒子来建立样本的图像。
Only relatively pristine material has the goods Landman is after, so his team USES a scanning electron microscope (below), which utilizes a beam of electrons to image surfaces, to find the best nacre.
只有相对原始状态的材料才拥有兰德曼所需要的研究对象,因此他的研究小组必须使用利用电子束表面成像的扫描电子显微镜(下图)去寻找最好的珍珠层。
