Abstract.
The creep behaviors of these materials cannot be explained generally by a simple composite creep model based on the bulk properties of the two constituent materials [9, 13].
Therefore, stress relaxation experiments can be used indirectly to characterize creep behaviors of the materials.
Presumably, Tg for the glassy phase in the present (MgO+Al2O3+Y2O3)-doped Si3N4 materials should be below 950∼970°C.

The parameters for cable force measurement (such as the geometric and material parameters of cables) usually come from design drawings and construction fields, and some experiments may be performed to get them when necessary.

According to the phenomenon, in process of injecting artificial-interlayer, because pressure drop occurs around well bore and material balance relationship of reservoir, so interlayer is injected, oil-interlayer interface becomes deformed and presents a downward bend shape.
