A relationship between the accepting powers of sub logarithmic space bounded two way alternating pushdown automata with and without 1 inkdot is investigated.

具有1个墨水点的和没有墨水点的亚数空间限定交替式下推自动机之间的关系进行研究。

The big disadvantage is the loss of accuracy and resolution, but some digital picoammeters combine accuracy and dynamic range by combining autoranging and digital log conversion.

这种方法，较大的缺点是损失了准确和辨率。然而，也有些数字式皮安表，采用自动量程和数字数变换的方法，这可将准确和宽动态范围结合了起来。
