[Purpose/Significance] Many scholars have studied the influencing factors of mobile government users' usage intention. Reviewing a large amount of literature, we found that the existing empirical research results in this field are inconsistent. Therefore, we need to clarify further the primary factors and moderating variables that affect mobile government users' willingness and reveal the specific reasons for the differences in results. Finally, we will try to obtain the universal conclusion and provide a reference for improving the relevant theories and researches on user information behavior. [Method/Process] We selected 8 antecedent variables and 4 moderating variables affecting users' usage intention, 45 Chinese and foreign literatures, 27 795 samples, and 139 independent effect values in the meta-analysis. [Result/Conclusion] Performance expectation (r=0.586), effort expectation (r=0.538), trust (r=0.590), social influence (r=0.549), safety (r=0.489), compatibility (r=0.645), quality of service (r=0.588), and information quality (r=0.549) have significant positive effects on the usage intention of mobile government users. Group category, education level, social culture, and mobile government category moderate the relationship between the above 8 variables and mobile government users' usage intention.

Large scale fire tests of building external wall insulation system were conducted. In the experiment, thermal-couples were mounted to measure the insulation system surface temperature and the gas temperature inside rooms at the second and third floors. Photos were also taken during the fire tests. The measurement provides information of the ignition and fire spread of the external insulation system which consists of surface protection layer, glass fibre net, bonding thin layer, anchor and the load bearing wall. Comprehensive simulations of the fire tests were carried out using an advanced CFD fire simulation software Simtec (Simulation of Thermal Engineering Complex) [1, 2], which is now released by Simtec Soft Sweden, with the turbulent flow, turbulent combustion, thermal radiation, soot formation, convective heat transfer, the fully coupled three dimensional heat transfer inside solid materials, the ‘burn-out' of the surface protection layer and the pyrolysis of the insulation layer, etc, all computed. The simulation is compared with experimental measurement for validation. The simulation well captured the burning and fire spread of the external insulation wall.
