Conduction , however , is most similar to the transmission of sound .

然而传导从原理上讲与声音传送最为相似。

Until now , controlling the conduction of heat through solid objects has been a tricky engineering challenge .

时至今日，控制热量通过固体传导对工程界还是一个棘手的挑战。

Collisions betweenparticles in the hot inner region transfer energy to particles in thecooler outer region via a process called conduction .

在较热的内部区域，粒子间的相互撞击将能量传递给了较冷的外部区域中的粒子，这一过程被称为传导。

However , unlike these other materials , all of the conduction occurs in a single layer of atoms in the sample .

不过，与这些其他材料所不同的是，传导过程发生在样本中一层单原子层。

Saline was used to provide conduction between the ultrasound transducer and skin , and the testes were warmed to 37 degrees centigrade .

盐被用来提供超声换能器和皮肤之间进行传导睾丸加热到三十七摄氏度。
