They can be used to track the mantle structure, degassing history, inhomogeneity, magma evolution and the genesis of natural CO2.
它们可对地幔结构、地幔脱气历史、大陆地幔不均一性、幔源岩浆演化和CO2天然气成因等研究提供独特的示踪作用。
The fracture occurres at heat affected zone (HAZ) of most fatigue specimens. This is due to the structure inhomogeneity and the higher hydrogen content of materials at HAZ.
疲劳试样多数断于接头的热影响区，造成这一结果的主要原因是热影响区的组织不均匀性和氢含量相对较高。
