With a view to knowing more about how NaHSO〓 increased Pn in higher plants, we studied the effects of NaHSO〓 on the cyclic electron flow around PSI in wheat (Jing 411) and rice (Shan-you 63). It was observed that the transient increase in chlorophyll fluorescence after the termination of actinic light was increased and the half-time of re-reduction of P700〓 was shortened in both rice and wheat leaves, indicating that cyclic electron flow around PSI was accelerated by NaHSO〓 treatment.

为探究NaHSO〓促进高等植物光合作用的机理，我们研究了NaHSO〓对小麦（京411）和水稻（汕优63）围绕PSI的循环电子传递影响，实验发现低浓度NaHSO〓可促进小麦和水稻叶片的叶绿素荧光在作用光关闭后的短时上升以及缩短叶片在远红光后P700〓再还原的半时间，表明NaHSO〓可以促进小麦和水稻的围绕PSI的循环电子传递。

In accord with the promotion in the photosynthetic oxygen evolution and ATP content, the transient increase in chlorophyll fluorescence after the termination of actinic light was increased; and meanwhile, the half-time of re-reduction of P700〓 in the presence of DCMU after a pulse light under background far-red light was shortened by approximately 30%, indicating that cyclic electron flow around PS1 was accelerated by the treatment.

与此同时，我们还发现经NaHSO〓处理后，蓝藻细胞的作用光关闭后叶绿素荧光瞬时上升的幅度增加，同时在远红光背景下和DCMU存在时，饱和闪光后蓝藻细胞P700〓再还原的半时间缩短约30％，表明低浓度NaHSO〓溶液处理能够促进蓝藻细胞围绕PSI的循环电子传递。

Chlorine dioxide whose concentration is 75mg/L can keep spinach fresh and green for more than 12 days.

For a same reaction time, when the H O concentration was increased, the redox potential was also seen to increase.

对于相同的反应时间，当何浓度增加，氧化还原电位，也被增加。

Microflora of soil reflected comprehensive effect including various factors such as soil nutrition, submerged time by tide, concentration of oxygen, redox potential, salinity and so on.

土壤微生物类群也反映了土壤养分状况、浸潮时间、O〓含量、氧化还原势和盐分等因素的综合影响。

On the basis of the animal model of blood stagnated disease builtup by infusing high molecular weight dextran to sheep,the effect andmechanism of electroacupuncture to activate blood circulation and re-move blood stasis were studied.

对电针前后血瘀症模型绵羊血液流变学指标变化的观察发现，电针后血瘀症模型绵羊的全血粘度、还原全血粘度、血浆粘度、红细胞聚集指数和血浆纤维蛋白原含量均显著降低，红细胞电泳时间显著缩短，证明电针具有活血化瘀，改善血瘀症模型绵羊血液循环的作用。

In order to disclosure the reason why the electrocatalysis activeness and selectivity droped after being used several hundred hours continuously, the x-ray diffraction, scanning electron microscopy and energy dispersive spectroscope have been used to characterize the surface condition variations of Monel metal. The results indicated: Monel metal belongs to the Cu-Ni alloy around the electrolysis experiment.And after being used for 600hr, the surface layer element composition and geometry distribution of the alloy changed, namely in the alloy the Cu element /which superficial free enthalpy was smaller,"concentrated" to the alloy surface,and formed one kind of marble structure microcrystallite.Thus the electrode surface becamed rough a

为了揭示蒙乃尔合金阴极在连续使用数百个小时后电催化活性剂选择性下降的原因，采用X射线衍射仪、电子扫描电镜和电子能谱分析仪对电解实验所用的蒙乃尔阴极材料在电解实验前后的表面状态进行了表征，结果表明：所使用的蒙乃尔合金阴极材料在电解实验前后均属于Cu-Ni合金，使用600hr后，由于表面层元素组成和几何排布发生了变化，即合金中表面自由焓较小的Cu元素向合金表面&富集&，形成一种大理石结构的微晶，表面粗糙、不均一，这是造成其对硝基苯电还原的催化活性及选择性随着使用时间延长而逐渐下降的主要原因，同时也为此类电极的修饰改进提供了方向。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
