Factor significance sequence is HF > pickling temperature > pickling time > HNO 3. The optimum process condition of pickling on the WK stainless steel sheet is HNO 3 12%, HF 2.5%, pickling temperature 65 ℃ and pickling time 35 s. Factor significance sequence is HF > HNO 3 > pickling temperature > pickling time.
Via analyzing the annealing process condition to semisolid cast iron and the observation of microstructures, the evolution mechanism of the semisolid organization was discussed, and the effect of graphite annealing to the mechanic properties of semisolid cast iron plank was also researched.
On the basis of foreign documents the process condition of various metal PWHT stipulated in some national industrial standards are analysised and compared,and the notices of PWHT of dissimilar steel and clad steel plate are explanied in special.
We adopted liquid flux method as pretreatment method of hot-dip galvanizing process,withproper technical conditions as follows: the mixture of ZnCl2 and NH4Cl solution as the flux ofgalvanizing, temperature 460℃, liquid zinc with different contents of Ti, Mg as bath.
Prognostication of Technical Conditions for Low-Orbit Spacecraft with the Use of Neural Networks
These investigations can be used in developing diagnostic criteria for assessing technical conditions of thin-wall structures with the help of acoustic and fiber-optic methods.
People have shown great interest in how to make these huge glazed bricks at the ancient technical conditions, because it is very difficult to manufacture such huge bricks even with the modern technology.
Strict causality ensures determinacy under certain technical conditions, and delta-causality ensures the absence of Zeno conditions.
We show that, with some technical conditions, an Abelian monoidal category admits a monoidal embedding into the category of bimodules over a ring.
