The daily take-off periodicity of the brown planthopper and its seasonalvariations were observed in 1978.Adults moved up to the top of rice plant fromthe base when they were going to migrate,and then flighted straight away.Insummer and autumn the mass take-off of adults occurred before sunrise and sun-set,presenting a bimodal crepuscular type,while in late autumn,it occurred inthe afternoon,presenting a unimodal day type.Some biological and environmental factors relating to the take-off of brownplanthopper were examined.The migrants were found to have immature ovaries,lesswing-loading,hypertrophic fat bodies and less water content.After applicationof JH ZR-619,owing to the acceleration of ovarian development and increasedwing-loading,the flighting activity was decreased significantly.The food condition is an important factor affecting the take-off.The take-off precentage of females feeding on yellow mature rice was higher than that offemales feeding on spike formation rice.This indicated that macropterous females(the migratory type )under suitable condition,might fall directly into the set-ting and breeding stage.The population density and the temperature had markedeffect on the pre-take-off period,but not on take-off percentage,while photo-period had no marked effect on the migratory take-off in our experiment.

褐飞虱起飞的行为和日周期节律己于1978年作了观察。在春、夏季节,成虫通常于日出前或日落后出现起飞高峰,呈“晨、暮双峰起飞”型,晚秋由于温度下降。成虫一般于暖和的下午起飞,呈“日间单峰起飞”型。室外调查和室內试验表明,褐飞虱长翅雌虫于卵巢发育至Ⅰ级末、Ⅱ级初时迁移活动最盛。此时,雌虫翅的负荷小,含水量低,脂肪体发达,有利于起飞迁移。在施用保幼激素 ZR—619后,由于促进卵巢发育,增加翅的负荷等原因,其飞行活动明显下降。食料条件是影响褐飞虱迁移的重要因素。在黄熟水稻上取食的雌虫,其起飞迁移百分率比取食孕穗水稻的为高。由此表明,迁移的长翅型成虫在适宜的食料条件下可直接进入繁殖阶段。种群密度、温度对起飞前期有明显的影响,而光照周期的影响不明显。

Results of beaker scale and large laboratory scale experiments on the deposition of manganese from chloride electrolyes are reported for conditions where fibrous electrolytic manganese dioxide is the anodic product. Anolyte and catholyte compartments were provided by dividing the cell with a porous porcelain plate. Graphite blocks were used as anode and stripts of titanium as cathode.The influence of various factors, such as current density temperature, concentrations of ammonium chloride and addittives on current efficiency of electrodeposition of metallic Mn have been studied. To produced one kilo-gram of metallic Mn as well as two kilo-gram FEMD an electric energy of only four to five kilowatt hour would be required. The current efficiency of electrolyzing metallic Mn arrives or surpasses the advanced level reported recently.

A simulated occluded corrosion cell was used to study the changes within corrosion cracks or crevices of Cr 18 Ni 9 Ti austenitic stainless steel in NaCl solution. As anodic currents passed the cell a series of changes took place, the most important of which were pH fall and Cl- migration. It was found that the pH fall was proportional to current density and time of current flowing. Consequently, pH fall was a function of the quantity of electricity passing the occluded anode. The pH in the occluded cell might attain negative value whencurrent density was 3.5mA/cm2 after 168 hrs. Meanwhile the Cl- migration into occluded cell increased the Cl- concentration 18 times as much as original concentration. As a rule, the Cl- migration versus unit anode area was proportional to time of current flowing. A linear relationship existed between Cl-migration in g-equivalents per cm2 of anode area and current density, and also a linear relation existed between Cl- migration per hour and current intensity. Consequently, the number of equivalents of Cl- migration into crack tip was proportional to the quantity of electricity passing it. It was interesting to discover that while each faraday passed almost always 1/2 g-equivalent of Cl-migrated into the occluded cell. This relationship did not change whatever were the concentration of bulk solution (from 0.01N to 5N NaCl), current density, temperature and time. Two empirical formulas regarding to the relationship between pH and Cr3+ concentration or Cl- migration respectively were derived based on the relationships between quantity of electricity passing and other variables' found in the present experiments, i. e.

本文系用模拟闭塞电池来研究Cr18Ni9Ti奥氏体不锈钢在NaCl溶液中闭塞区内化学和电化学状态的变化.当电流通过闭塞区时,溶液PH值随时间下降,电流密度愈大下降也愈大,可达负值,电极所通过的电量与溶液PH成函数关系.CI~-在闭塞区内的浓集倍数与时间成直线关系,最高测到浓集达9—10倍.在一定电流密度下,与单位阳极面积相应的Cl~-迁入量与时间成正比.若以电流密度对单位时间、单位阳极面积相应的Cl~-迁入量作图或以电流强度对每小时Cl~-迁入量作图,均得直线关系.闭塞区内每迁入1g-eq·Cl~-,电极上通过电量为一常值,约为2F.这个关系不随电流密度、温度、时间及外部溶液含NaCl的浓度而变化.根据实验数据与上述Cl~-迁入量、金属溶解量和闭塞区通过电量的关系,导出闭塞区溶液PH与Cr~(3+)及Cl~-的克离子数的关系经验公式,如下:PH=-2.60—log[Cr~(3+)]PH=-1.84—log[Cl~-]
