查询词典 reduction

The basic data obtained from the experimental research were calculated and disposed with computer and concluded an important principle of Li〓O by silicon thermoreduction. The factors affected the reduction such as temperature, pressure and time were dicribed by methematical equations. The relation ships of reduction rate with temperature, pressure and time were directly expressed by three-dimension figures. The relating mathematical equations described the process derived from research were proved to be coincided with the practice. Therefore, the obtained results were accurate and reliable and of important value.
