The results were as follows: The stomatal conductance of winter wheat flag leaves treated with 10–50 mg/L ALA were significantly higher than that of the control (0 mg/L ALA); however the promotive effects of 10–50 mg/L ALA on stomatal conductance at flowering and milky stage was stronger than at dough stage. Applying 10–50 mg/L ALA increased the net photosynthesisrate of winter wheat flag leaves.

结果表明，10～50 mg/L ALA处理的叶片气孔导度高于不喷施的对照，但在开花期和乳熟期对气孔导度的促进作用大于腊熟期；叶片净光合速率也明显高于对照。

The first is termed aero-optic and involved optical transmission through aberrating fluid layer whose thickness, L, is smaller than or comparable with the viewing aperture dimension, A, and the turbulence scales, A , are smaller than or the order as the layers thickness:The second category, atmospheric propagation, involved optical transmission through the aberrating medium over very long propagation distance compare with the viewing aperture size, and the turbulent scales of note are generally less than or the same order as the propagation distance:Depending on the atmospheric conditions, for ground-based observatories, wave-front sensor operating at 300HZ can adequately resolved both the important spatial scales and the temporal evolution of the atmospheric-turbulence-induced aberrating wave front over viewing aperture associated with relatively large telescope.

第一类问题光学畸变发生在&近场&较短的光路上，即流层厚度L，光束直径A，以及湍流尺度Λ三者之间存在关系式：ΛA≤L≤A第二类大气传输问题光学畸变则发生在较长的一段光路上，L，A，以及Λ满足： A＜＜Λ≤L对于地基情况下的大气光学传输，300Hz的波前传感器就能实时地测得光波前畸变包括时间、空间频率的相关信息，为我们的自适应光学系统的设计、制造以及进行相关的自适应校正都有着相当重要的指导意义。

SOD activity was at peak in 5 mg/L Zn treatmenat, indicating greater ability to eliminate ROS caused by excessive Zn. Zn contents in roots and thalluses of duckweed in vivo increased significantly with increase of Zn concentration in solution at 0-5 mg/L Zn. When Zn concentration was higher than 5 mg/L, Zn accumulation in duckweed was no more increased significantly. And, the plant was damaged by excessive Zn.

结果表明：在Zn浓度为5 mg/L时，浮萍生物量并没有受到明显的影响，表现出较强的抗性；SOD酶活性也最高，表明清除氧自由基的能力也较强；Zn的积累随处理浓度增加而增加，在5 mg/L Zn处理时，也基本达到饱和，超过该浓度，吸收量则无明显的变化，同时浮萍也明显受到伤害。
