The photosynthetic characteristics during development and senescence of sweet potato leaves were measured by using PQW infrared gas analyzer.
利用红外气体分析仪测定甘薯叶片发育和衰老过程中光合特性的变化。
It was found that, if the interval between the electron and the donor ion was different, the variation of polarization potential with the donor ion position z_0 in the PQW would be different also.
结果表明，电子与施主离子间的距离不同，则极化势随施主离子位置的变化关系也不同。
