PBO

The dissolution properties of Pb ( NO 3 ) 2, PbO , and Pb 3 ( CO 3 ) 2 ( OH ) 2, were expressed as : brown soil & gt ; black soil & gt; meadow soil ( P & lt; 0.01 ).

Pb ( NO3 ) 2 、 PbO 和Pb3 ( CO3 ) 2 ( OH ) 2溶解性表现为棕壤 & gt; 黑土 & gt; 草甸土 ( P & lt; 0.01 ).

PbO deficiency only affected dielectric loss very weakly.

而铅欠缺对介电损耗影响很小.
