Upon CV and DPV experiments, the reduction and oxidation potential of these porphyrins were shown to be similar to each other. This suggests that different PAHs ethynyl substitutes would have similar effects on electrochemical properties of the porphyrin molecule.

在电化学探讨部份，接上不同多环芳香族取代基的紫质分子之氧化还原电位彼此都相当类似，表示这些紫质光敏剂的能隙相当接近，不同的多环芳香族取代基对於紫质分子的电化学性质影响程度相当接近。

Results showed that the monochromatic lights were advantageous to the Pchlide reduction and biosynthesis for etiolation seedling of Phaseolus radiatus in illumination for 0.5 h at first. The monochromatic light did not favor for Chlide esterification after illumination for 2 h. Chlide esterification was controlled by the cell nucleus gene, because Chlide esterification rate was restrained to the seedling leaf of P. radiatus.

结果表明：绿豆黄化幼苗在光照最初0.5h，单色光有利于Pchlide的还原和新Pchlide的生物合成；光照2h后，单色光不利于Chlide的酯化；CH明显抑制绿豆幼苗子叶Chlide的酯化速度，说明Chlide的酯化是受细胞核基因控制。

It employs the complex-valued step function to build neural model, then constructs network structure and decides the number of neurons; it adopts complex-valued Hebbian rules and inner product way to calculate the net weight matrix; then it analyzes the convergence of the network by taking advantage of the definition of energy function. In the image pre-processing stage, 2-dimensional Fourier Transform and Euler's formula are used, respectively, to transfer a gray-scaled image into phase information needed by the complex-valued neural network when stores the traffic sign. In the image post-processing stage, phase inverse transformation is used to change the phase image to gray-scaled image.

采用复数阶跃函数构建了神经元模型，建立了复数Hopfield神经网络结构，并且确定了网络中神经元的个数；借助复数Hebbian学习规则和复数内积法给出了网络权值的确定方法；借用复数网络能量函数的定义，说明了复数识别网络的收敛性；在前期的图像数据处理部分，分别使用离散二维傅里叶变换和欧拉公式，给出了将灰度图像数据转化为复数网络所需要的相位信息的方法，实现了网络对路牌的记忆存储；在后期的图像还原部分利用相位逆变换的方法，实现了相位图到灰度图转化。

Oxygen that is evoluted in the anode and arsenic acid will have oxidation-reduction to produce arsenic acid. It can evolute a great amount of hydrog...

在铜含量较低时阴极析出大量氢气，阳极析出氧气，极大地浪费了电能；在析出氢气的同时逸出砷化氢，砷酸、亚砷酸在阴极直接发生还原反应也产生砷化氢气体，从而严重地污染了环境。

Matting were as granula convex peak exorbitance, fotographic and photoptic layer of PS gap is too large, resulting in a fine image so that the density of hihglights part of the net-point drop in the level of the gradient image is missing.

不净背颗粒较大，会变成颗粒凸峰过矮，胶片与PS版感平层的间隙过大，以致精粗影像难以还原，矮平局部网不背的稠度回升，图像阶调条理迷失。

The results were as follows: Being infected virus, the electrolyte exosmosis rate of tobacco leaf was increased , while the increase rate of the leaf being injected ion was less than that of the control. The activities of SOD?

结果表明：病毒侵染后烟草叶片电解质外渗率增大，但离子注入后烟草的电解质外渗率增幅小于对照；病毒侵染后烟草叶片的超氧化物歧化酶、过氧化物酶、硝酸还原酶的活性及叶绿素含量均有所下降，但离子注入后烟草的上述酶活降幅较小；CAT活性在接毒后呈先低后高的变化，而对照在接毒后 10天该酶活性高出离子注入烟草 2倍多，随后剧降，到接毒 2 5天时仅为离子注入处理烟株 1/ 2。
