Peeping into the structure of erythrocyte and hemoglobin would make human understand the oxygen carrying capacity of erythrocyte and the pathology of red blood cells disease, which provided the theoretical basis for diagnosis and treatment.

It was demonstrated by oxygen equilibrium curve that modified hemoglobin with DBBF (DBBF-pHb) under hypo-oxygen condition had better oxygen-carrying property than stroma-free hemoglobin.

In view of the problems that underground information equipments are self-governed and(difficult) in maintenance,a kind of multifunction portable terminal based on WiFi was designed.
