primary secondary tertiary processes of copper

Basic modelling of tertiary creep of copper SpringerLink

Jan 04, 2018  高达10%返现  Technically, both primary creep and tertiary creep are of utmost importance. For fcc alloys that cover a large fraction of the technically used creep-resistant materials, the creep strain in the primary stage is often of the same order as that in the secondary stage. Tertiary creep is also of major technical significance since it controls creep ...

Jan 20, 2001  Primary prevention means avoiding occurrence of a disease. Secondary prevention in the context of preeclampsia implies breaking off the disease process before emergence of clinically recognisable disease. Tertiary prevention means prevention of complications caused by the disease process, and is thus more or less synonymous with treatment.

dustrial processes usually results in a mixture of primary, sec-ondary, and tertiary amines. However, the ratio of products can be tuned by reaction parameters, such as residence time and excess of ammonia. In analogy to ammonia, primary or secon-dary amines can be employed in these transformations to obtain secondary or tertiary amines.
