A low current measurement system may also require significant settling time be fore the expected accuracy can be obtained.

对于小电流测量系统，也需要足够的稳定时间才能够获得预期的准确度。

By making some necessary approximations, the algorithm used for this system is able to avoid solving directly system of nonlinear equations without losing the expected accuracy.

该系统所采用的算法由于作了某些必要的近似处理，避免了直接解非线性方程组同时又满足了精度要求。

Test results indicate that the algorithm can acquire about 16% of the useful expanded rules to cover 93% of the annotated positive examples and can improve the expected accuracy from 51% to 81%.

实验结果表明：现有算法以16%的有效扩展规则覆盖了93%的标注正例，并使预期精度从51%提高到81%，显示了这套规则学习和评价方法的有效性。
