sandwiching

The third objective, efficient design, involved sandwiching the nanostructured bismuth telluride between two copper plates and then enclosing the upper plate ( the one coated with the light-absorbing oxides) and the bismuth telluride in a vacuum. The copper plates conducted heat rapidly to and from the bismuth telluride, thus maintaining the temperature difference.

第三个目标、高效的设计，包括三明治式的结构，纳米级碲化铋在两个铜片之间，并封闭上面的铜片（一面覆盖吸光的氧化物），碲化铋则在真空中，铜片传导热量迅速到碲化铋。

The cases of the two groups, their peripheral blood TNF-α and Fn Levels, in the 1st and 7th days of their life, were assayed and comparatively analyzed by a double-antibody sandwiching enzyme-linked immunosorbent assay ( ELISA) and immune transmission turbidimetry, respectively.
