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

对具有1个墨水点的和没有墨水点的亚对空间限定交替式下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分辨率。然而，也有些字式皮安表，采用量程和字对的方法，这可将准确和宽态范围结合了起来。
