摘　　要：蒙特卡罗方法可用随机投点法及期望估计法在计算机上模拟求积仪，对示功图进行积分从而为平均指示压力的求取提供了新的方法。并通过计算实例，表明选取适当的随机数列和投点数后，可取得较高计算精度。This paper presented a new method of calculatin I. M. P. E of internal combustion engine by using Monte Carlo simulation. The indicator diagram was integrated by meams of computaitonal simulating intefgraph with both methods of random throw dot and expectation estimte.An example showed that this method could obtain highter calcuation accuracy so long as the random sequence and the throw dot number were reasonably selected.
