In the calculation of the optical constants by the Kramers-Kronig transform relations,it is essential to carry out a numerical integration on the discrete experimental data of the reflection spectrum.
针对利用K-K转换关系计算光学常数时,需要对实验测得光反射谱的离散数据进行数值积分,而利用通常的数值积分方法存在较大的偏差,提出了一种新的数值积分法,即双抛物线比例内插法(DPPIM)。
KAT1 and AKT1 are the first K~+ channel genes cloned in plant,while HKT1 is the first K~+ carrier gene cloned in wheat.
植物中最先克隆出来的高亲和K+转运体基因,是小麦的HKT1。
K~+ transporters are generally composed of high-affinity and low-affinity two part.
在分子水平上,高亲和吸收主要由KUP/HAK/KT及HKT家族的K+转运蛋白来承担;而Shaker、KCO等家族的K+通道蛋白,则主要在植物的低亲和吸收中发挥重要作用。
