| 摘要: |
| 编制了求解时间相关二维中子输运问题的并行计算程序，并在YH-1计算机上进行过许多验证计算。对六个临界装置的计算表明，临界参数的计算值与实验值之间的偏差在参数值的实验误差范围之内，这证明计算程序是正确的。不同并行算法的计算结果完全相同也证实了程序编制的正确性。计算表明，并行程序的计算效率比相同参数下的串行程序提高约30倍以上。为了尽可能提高并行计算的效率，除了采取通常的向量化技巧外，在算法上提出了并维技巧和斜对角扫描的方法。 |

| Parallel Algorithm of Two Dimensional Unstable Neutron Transport |

| Abstract: |
| The parallel computer programs to solve time-dependent two dimensional neutron transport problem were drawn up, and many test calculations were completed by using the YH-l type electronic computer. The calculations for the six critical assemblies show that the discrepany between the calculation value and the experimental result of the critical parameter is less than the experimental error of the data. This proves that the computer programs are effective. The validity of the programs is also verified by the fact that al1 calculation results of the different parallel algorithm are identical. The，calculations show that the efficiency of the parallel computing is roughly thirtyfold of that of the serial program when the data are the same. To enhance the efficiency of the parallel computing, we developed a combining dimension technique and an oblique diagonal sweep method in addition to using the general parallel technique. |
