Flow Accelerated Corrosion is an important aging mechanism for water and water/steam piping made of carbon steel or low alloy steel in both nuclear power plants and fossil power plants. Accidents in Surry Unit 2 in USA and Mihama Unit 3 in Japan, caused by pipe rupture due to FAC, led to severe casualties. The experience, mechanism and countermeasures about the aging management of FAC in nuclear power plants are summarized in this paper.

管道流体加速腐蚀是核电厂和常规电厂碳钢或低合金钢材料汽水管道的一个重要的老化机理，历史上曾发生过美国萨里核电站2号机组和日本美滨核电站3号机组管道破裂等导致人员伤亡的严重事故；本文简要总结了核电厂管道流体加速腐蚀的经验教训、机理及其老化管理的一些方法和对策。

Plants were hydroponically grown in solutions containing 3 mM Ca(NO3)2 or 3 mM NH4NO3 as nitrogen source. Mature plants were harvested eight times in one day at a 3 hr. interval from 8:00PM Aug. 12 to 5:00PM Aug. 13. Diurnal variations of the shoot nitrate content were observed in either Ca(NO3)2 or NH4NO3 treatment. Shoot nitrate content of Ca(NO3)2 treated plants were higher than those treated with NH4NO3 at every harvest. The average shoot nitrate content of lettuce with Ca(NO3)2 was 0.68% of the dry weight, and it was 0.29% for the NH4NO3 treated lettuce. The fresh weight of the NH4NO3 treated lettuce were 1.43 or 1.2 fold heavier than those with Ca(NO3)2 treatment for shoot or root respectively.

R36品种以3mM硝酸钙(6mM N)或3mM硝酸铵(6mM N)处理，於8月12日下午8点开始采收，每隔3小时采收一次，采收至8月13日下午5点。3mM硝酸钙与3硝酸铵两种养液处理的地上部硝态氮含量皆有日变化，而且在8个采收时间，3mM硝酸钙养液处理的地上部硝态含量皆高於3mM硝酸铵处理。8个采收时间的硝态氮含量平均，3mM硝酸钙养液为乾物含量的0.68%，而3mM硝酸铵处理为0.29%。3mM硝酸铵养液处理的地上部与根部鲜重分别为3mM硝酸钙处理的1.43倍及1.2倍。

Nowadays, the pest mites are increasingly becoming rampant, such as the spider mites, eriophyid mites and tarsonemid mites which can cause damage to crops and forestry plants and acarid mites which can harm plants both in storage and the field.

近年来，害螨为害日益猖獗，如田间作物上的叶螨、瘿螨和跗线螨，以及田间和室内均可发生的粉螨等。

Aims We investigated aerenchyma formation in stems of riparian plants Arundinella anomala and Salix variegate as affected by addition of ethylene and a-naphthalene acetic acid under non-flooded conditions in order to ascertain whether phytohormone ethylene and auxin are direct stimuli for aerenchyma formation in flooded plants.

为了探究乙烯和α-萘乙酸是否是水淹环境条件下植物体内通气组织形成的直接原因，对三峡库区岸生植物野古草和秋华柳在无水淹环境条件下施加乙烯利和α-NAA后茎中通气组织的形成情况进行了研究。

A tropical rain forest ; an ever-green forest that exists in tropical regions where precipitation is heavy all the year round ; there are vines , parasitic plants and overgrowth , as well as aerophyte besides those tall trees , bushes and herbaceous plants ; mainly distributed in the Amazon drainage basin in south America , the Congo basin , Malaysia , etc .

名 热带气候终年湿润地区的常绿森林群落。这些雨林区由于常年气候湿润多雨，除高大的乔木、灌木、草本植物外，还有繁茂的藤本植物、寄生植物、附生植物等。主要分布在南美亚马孙河流域、非洲刚果盆地及亚洲的马来群岛等地。例句去热带雨林里探险，必须扎上绑带。

Phenotypic plasticity and genetic differentiation are the two major strategies that alien invasive plants can adapt habitat heterogeneity.The polymorphism of invasive plants and the diversity of their dispersal way enable them occupying invaded habitat quickly,and dispersing with a far range.The breeding strategies that agamogenesis and amphigenesis can coexist and trade off according to the habitat and invasive stage can not only promote the invasive population erupted massively,but also directly affect the dispersal mechanism and regulate the genetic structure of the population.

表型可塑性和遗传分化是外来入侵植物对生境异质性的两种适应策略；散布体多态型和散布途径多种化，使外来入侵植物迅速占领入侵生境，并进行远距离扩散；无性生殖和有性生殖并存，并根据生境和入侵阶段权衡的繁育对策不仅使入侵种群大面积暴发成为可能，而且直接影响散布机制并对种群遗传结构具有调节作用。

Various technical barriers that have to be overcome are the establishment of transformation systems in agriculturally important food crops and regeneration of fertile plants from transgenic plants.

一些必须克服的技术障碍有：在重要的农业食品种植物中转换系统的建立和从转基因种植物中优质的植物的再生。

The result of TLC shows that the three plants of Ajuga contain analogical chemical composition. three plants all contain luteolin.A. decumbens and A.nipponensis all contain esdysterone exclude A.dictyocar. But the latter contained higher amount than the former. TLC of A.dictyocar shows more differences. Thin-layer chromatography can sever as evidence to identificate them.

薄层色谱的结果表明，3种药材的乙醚提取液中均含有木犀草素，且化学成分基本一致；除网果筋骨草外，金疮小草和紫背金盘的正丁醇提取液中均含有蜕皮甾酮，而前者的含量较高，网果筋骨草的色谱与其余二种存在较大差异，薄层色谱法可以鉴别这3种药材。
