heat conductivity

基本解释

This constant k actually is called the heat conductivity.
这个常数k就叫做热传导系数。
Because TC4 alloy has low heat conductivity, high heat plasticity and good oxidability, low welding parameters should be selected.
由于TC4钛合金导热系数小，热塑性高，容易氧化，摩擦焊亦选用较小的规范参数。
Metals are elements that can be defined by their properties, such as ductility, toughness, malleability, electral and heat conductivity, and thermal expansion.
金属是根据可锻性，刚性，可塑性，电热导通性以及热膨胀度等特征来定义的多种元素的复合物。

They often have interesting properties, such as poor heat conductivity (which makes them good insulators) and low friction (which makes them slippery).

Because the two materials exhibit a high thermal conductivity, they allow the device to cool more efficiently while distributing said heat -- 25 percent quicker than the pure copper in many pieces of tech.

That does not affect their electrical conductivity, but nanoscale particles like this are known to scatter and obstruct the passage of heat through imperfectly understood quantum-mechanical processes.
