There are no data on how materials grown with different technologies compare in terms of their
metal content.
Only gold was found in the "bad" areas in 1.5 to 5 times higher concentrations than in the "good" areas of all three materials.
Baysix and EFG materials also contained metal precipitates, but the number of large precipitates and the average size of these precipitates were smaller, a direct consequence of these materials containing less transition metals.
The operations of the Advanced Light Source at Lawrence Berkeley National Laboratory are supported by the Director, Office of Science, Office of Basic Energy Sciences, Materials Sciences Division, of the U.S.

So it is a constraint function of performance, geometric and function and can be expressed as[3]:
(1)
Thereinto, F means function, and specific function module corresponding specific structure; P means performance restrictions such as load, material, stress, strain and so on, and those constraints determine the values of structure parameters; G is geometric structure parameters.
