The result showed that with the increasing of density, plant height was increased, stem diameter and ear diameter was decreased, ear was shorten, rare top length、No. of ear nod、ear height was increased;brace root number and total root number was decreased, the rate of root dry weight was increased within farming layers; population dry matter accumulation was increased and plant dry matter accumulation presented the opposite trend; ear linage、kernels per ear、100-kernels weight、double-ear rate、plant yield was decreased, yield was increased and decreased successively.

结果表明：随群体密度的增加植株高度增高、茎粗、穗粗变细、果穗变短，秃尖长度、穗位节数和穗位高度呈现增加的趋势；气生根与总根数减少，耕层根系干重比例增加；群体干物质积累量随密度增加而增加，单株干物质积累量呈相反的趋势；穗行数、穗粒数、百粒重、双穗率、单株产量均随密度的增加而减低，群体产量先增后降。

The inconsistency ofchanging trend of the breakdown potential with NDE implied that NDE of aluminum was probably caused by low valence Al+ chemical reaction in solution.

不同阴离子使铝的负差数效应系数变化趋势和孔蚀活化电位变化趋势的不一致性说明铝电极的负差数效应现象是中间产物的低价离子在溶液中的化学反应造成的。

The electropinning parameters (voltage, concentration and C-SD) influenced the mechanical properties of electrospun nylon 6 fiber mats. With increase of the solution concentration, the breaking stress and strain of the mat became large. The effect of C-SD was contrary. The nylon 6 fiber mat electrospun on the high voltage had low elongation but high strength.

The effect of Profenofos on GPx activities and on the co ntents of GSH and CAR in Phaeodactylum tricornutum and Platymonas helgolan dica were studied. The results indicate that the GPx activities of two species of microalgae declined, and the contents of glutathione and carotinoid of algal c ells decreased under high concentration of Profenofos.

摘 要 实验以三角褐指藻和青岛大扁藻为材料，进行了丙溴磷农药对海洋微藻的抗氧化防御系统成份— GPx 活性和GSH、CAR含量的影响研究，结果表明，在丙溴磷胁迫下，微藻的GPx活性呈现下降趋势，GSH和CAR含量也表现为下降趋势，并且胁迫的时间越长、胁迫的强度越大它们下降的幅度也越大。
