| 摘要: |
| 用更逼真的核模型(费米型的核子密度分布)进行了模拟计算，计算中用折线近似粒子的曲线运动轨迹，并考虑了粒子在核表面处的折射和反射。用自由核子截面确定核内的碰撞，并且自始至终地使用了统计抽样技术。入射粒子的能量被限于350Mev 以下，即π介子不大可能产生的能量范围。初步计算结果与实验数据进行了对比。 |

| Abstract: |
| Simulation calculation were performed by using a more realistic nuclear model (a Fermi-type distribution of the nucleon density).In the calculations，a broken line was used for approximate treatment instead of the curve trajectory of the particle motion，the refraction and ref1ection of the particles at the nuc1ear surface also were considered. The free nuc1eon cross section were used in determining the collisions within the nucleus，and the statistical sampling techniques were used throughout. The energy level of the incident particles was restricted to the limit below 350Mev，i.e. ，the energy range in which pion can't be likely produced. The elementary calculative results were compared with experimental data. |
