Ca2 + stimulates enzymatic systems that help trigger the body's immune defences - the investigators wondered if Pb2 + did the same.
Ca2 +可以激发酶系统，从而帮助引发人体免疫反应——科学家们想知道Pb 2 +是否有相同的效果。
The results demonstrated: Pb2+ suppressed the expression of H-current, decreased the voltage sensitivity and increased the activation voltage.
结果表明：铅抑制了H -电流表达；降低了H -通道电压敏感性和升高了H -通道的激活电压。
Amatore says that although most lead compounds, like galena, are insoluble, compounds like laurionite 'can dissolve a little bit to produce Pb2 +.'
阿玛托说，尽管诸如方铅矿一类的大部分含铅化合物都是不可容的，像羟氯铅矿这样的化合物还是“可以微溶于水，并产生Pb 2 +(二价铅离子)”。
The studies were carried out on the effect of Pb2+exposed for 1 months on the mucous cells of the Yellow River carp by method of AB-PAS combined staining.
利用阿新蓝过碘酸雪夫染色方法，研究了铅浸泡对鲤鱼黏液细胞的影响。
The key difference in this study was the presence of a single gene from the H3N2 human virus: the PB2 protein, which gave the hybrid viruses the ability to spread easily among the lab mice.
这项研究中一个关键的不同点就是H3N2人类流感病毒中存在一个蛋白基因：PB2蛋白，它的存在使得杂交病毒具有了在实验小鼠之间轻易传染的能力。
