结果显示,在高的光辐射下羊栖菜藻体的有效光化学效率和相对电子传递速率急剧下降,两种N水平条件下藻体的光化学活性下降趋势一致;在全波长太阳辐射条件(即高的光辐射和紫外辐射同时存在)下它们的下降幅度更大,而N加富条件下羊栖菜藻体的相对电子传递速率要高于对照N水平下生长的藻体,表明N加富的生长条件使得藻体具有更高抵御紫外辐射的能力,这可能是与N加富生长条件下的藻体中含有较高含量的紫外吸收物质和类胡萝卜素有关。
补充资料:催化剂表面有效利用率
分子式:
CAS号:
性质:将通常测定的反应速度与消除内扩散后所测定的速度之比,定义为催化剂表面有效利用率。用以表征催化反应受颗粒内扩散控制的程度。工业上有许多反应是在内扩散区进行的,其催化剂的表面利用率差别很大。如苯酚在Ni催化剂上加氢时表面有效利用率为72%。使用5mm合成氨催化剂颗粒时,表面有效利用率为72%,而用2mm颗粒时,接近100%,即反应在动力学区进行。
