Investigation of the Absorption Spectrum of InAs Doping Superlattice Solar Cells.

InAs doping superlattice-based solar cells have great advantages in terms of the ability to generate clean energy in space or harsh environments. In this paper, multi-period InAs doping superlattice solar cells have been prepared..

[Clinical study of the effect of verapamil-procaine compound in prevention and treatment of acute respiratory distress syndrome after high risk operation].

Objective: To observe the effect of verapamil-procaine compound (V-P) on prevention and treatment of acute respiratory distress syndrome (ARDS) subsequent to high risk operation.

Methods: Altogether 150 cases of major operations with high risk of ARDS were enrolled for study. They were randomly divided into three groups.
