中文摘要：
SSW（Solar SoftWare）的能量电子产生X光子的轫致辐射积分计算发展到版本2时，其性能相比初始的版本1提高很多．在版本2的基础上，对这个积分进一步改进．通过对比几种轫致辐射积分方案，结果显示，最终的方案性能上比版本2可以快约2—5倍．在积分的精确性上比版本1及版本2均改进了很多，在缺省的积分控制精度下也不再产生光子谱的尖刺现象．而且，积分耗时不再敏感于积分上限取值．由于积分性能的提高，使得利用精确的轫致辐射截面计算轫致积分成为可能．结果显示，用精确轫致辐射截面比先前的近似截面积分的结果光子流量略小（≤4％），积分时间大约比先前使用近似截面多30％．
英文摘要：
The integral numeration of the hard X-ray bremsstrahlung spectrum based on the version 2 in Solar SoftWare （SSW） is developed by us. By comparing the cost times of the integral numeration with four methods, it is showed that the best method is faster than version 2 by about 2 to 5 times. It also shows that in comparison with previous version 1 and 2, the accuracy, the suppression of the spike structure and insensitivity to the upper limit of the integration are improved a lot with the best method. In addition, we test the integral numeration by using the exact bremsstrahlung cross-section instead of the present approximate one, and prove that the cost time is tolerable with our improved method.
