Analyses　on　the　Step　Responses　of　a　Thermally　First　Order　System with　the　Emphasis　on　Safety　Engineering　for　Chemical　Reactions …--Studies　on　Potentially　Hazardous　Reactions　（VII）

Abstract

Being　inherited　from　the　previous　paper，a　thermally　Grst　order　system　was　analyzed　theoretically with　the　emphasis　on　safety　engineering。　The　thermal　responses　to　a　step　excitation　were　brought into　consideration．　The　mathematical　relations　were　modified　into　convenient　forms　to　evaluate　the danger　oheactive　systems．　In　paticular，a　few　diagramatical　analyses　of　practical　data　were　proposed to　derive　the　safety　indexes.　The　mathenlatical　equations　and　variables　were　projected　on　the　practical models. The predlctions of potential hazards on the mathematical analyses were shown to be feasible．
