diathermancy是什么意思，diathermancy翻译
Diathermancy is a term used to describe the ability of a material to conduct heat without electrical conductivity. In simpler terms, it refers to the property of a material that allows it to transfer heat energy through vibrations of its atoms or molecules, without the need for electrons to carry the charge. This unique property of diathermancy has numerous applications in various fields, including engineering, manufacturing, and medicine.
One of the most common examples of diathermancy can be seen in the everyday use of metal spoons to stir hot soup. Metal is a good conductor of heat, but it is also diathermantic. This means that when the spoon is stirred in the hot soup, the heat energy is transferred from the soup to the spoon and then to the air around it, without the need for electricity. This natural process of heat transfer through diathermancy is known as convection.
Diathermancy also plays a crucial role in the functioning of electric heaters. When an electric current is passed through a heating element, such as a wire or a rod, the resistance of the material generates heat. However, in order to effectively transfer this heat to the surrounding space, the material must also be diathermantic. This is why materials like copper and aluminum are commonly used in the construction of electric heaters, as they have high thermal conductivity and are also diathermantic.
In the field of medicine, diathermancy has found applications in the form of diathermy machines. These machines use high
