Results show that, this method could reduce the computational cost to 1/3 of original by decreasing the true and all-over tracing times.

结果表明，该方法通过减少真实、遍历式追踪的次数，能将普通径迹法射线追踪过程的计算量减少到原来的1/3左右。

Another method is to abandon original system, carrying out unified on the basis of success at pilot spot. The cost is as large as the previous way.

另一种建设方式是对各级系统推倒重来，在试点成功的前提下统一建设，但所付出的资金、人力消耗、以及对新系统的开发、培训和适应成本也是同样巨大的。

Examining the original Bush tax-cut proposal using the new method produces a ten-year "cost" that isn't much different from that arrived at using the old one.
