The body in the fire are mostly burning， and the judge is during his lifetime or after death to burn ，which plays an important role in the identification of fire murder Devastating fire， a number of important physical evidence is burned， thus affecting the burned bodies of the nature of death identified， the investigation of cases a certain degree of Therefore， the analysis and understanding of the difference in lifetime burned burned his body after death， and of great significance to the investigation of the This thesis is a case to analyze and describe the similarities and differences of lifetime burned burned his body after I help him to answer撤消修改
The purpose of this study is mainly for the oxygen - acetylene flaming combustion process to produce the effect of the combustion process Its main forms in the combustion process is caused due to high temperature flamer tempered， once this happened is not achieve ideal result， welding is easy to make flame back to burn the Therefore a control device of the phenomenon is quite This is mainly due to the relatively high temperature flamer caused by such devices a Mainly in oxyacetylene cutting installed in the gun This device is concise， outer wall and inner choose copper and iron welding formed by choice， outer wall hollow ferroalloy were used for welding of inlet and outlet water two ZuiZ It forms a hollow internal cooling device， the coolant Through testing the device installed in flames shot after the fire after cutting temperature are obviously Install the device is not install the device than lower temperature burning， Through testing the device can be found after temperature control by gun fire， burning full， easy cause This device such as recognized by acetylene flame cutting to oxygen， the production process， the main advantage of low cost， easy to But there may be confined to small-scale human Keywords: oxyacetylene cutting clamp
