摘　　要：In order to shorten the operation time of the Monte-Carlo simulation of photon transmission in the thicker high-scatterance matter,the fiber is chosen as the receiving device.At the same time,the light source and the receiving surface are aligned.According to the distinction of the anisotropic factor(g),increasing the restricted conditions could improve the simulation speed greatly.And the approximate restricted conditions could cut down the waste time of operations.Simulation results indicate that compared with the Monte-Carlo simulation,the optimized one could save 67% time,and ensure the precision higher than 0.7% in the thicker matter.In order to shorten the operation time of the Monte-Carlo simulation of photon transmission in the thicker high-scatterance matter,the fiber is chosen as the receiving device.At the same time,the light source and the receiving surface are aligned.According to the distinction of the anisotropic factor（g）,increasing the restricted conditions could improve the simulation speed greatly.And the approximate restricted conditions could cut down the waste time of operations.Simulation results indicate that compared with the Monte-Carlo simulation,the optimized one could save 67% time,and ensure the precision higher than 0.7% in the thicker matter.
