Various types of materials, such as stainless steel, Co-Cr-M and Ti alloys, are used as biocompatible materials for the implant treatment [1].
However, these materials have both merits and demerits and are insufficient to satisfy the characteristics required for the biocompatible materials.

And the bottom of the U-shape tube is close to ignition hole which is the top of fixed grating and was filled with some porous ceramic materials.
Firstly, biomass materials was fed into the domestic straw gasifier and then the biomass materials are lighted; secondly the thermocouple was inserted into the inside of gasifier through ignition hole to measure the temperature of the reaction.
