Based on the analysis of the contents of Cu, Pb, Mn, Zn, and Cr in the rhizosphere sediments of Phragmites australis and Scirpus mariqueter at tidal flat in Changjiang Estuary, the following conclusions can be drawn.

长江口滨岸潮滩芦苇与海三棱草根系、茎叶以及根际沉积物中Cu、Pb、Mn、Zn、Cr的含量分析发现，Cu、Pb、Zn、Cr在根系中的含量较高，而Mn在茎叶中的含量达到总量的55%以上。

The content of Mn in stems and leaves can account for up to 55%. Scirpus mariqueter can accumulate more heavy metals than Phragmites australis. And the heavy metal contents have se...

植物体内重金属含量一般在冬季富集；芦苇根际沉积物中重金属的含量秋季较低，冬季富集，而海三棱草根际沉积物中Cu、Pb、Mn均在秋季含量较高，Zn、Cr冬季含量最高。

With the parameters from published literature and experiments, we conducted forward analysis to compare soil organic carbon, carbon sequestration rate and soil total nitrogen dynamics of four different ecosystem types bare ground, Scirpus mariqueter, Phragmites australis, S.

通过构建九段沙生态系统碳氮模型并结合实测数据比较了互花米草入侵后生态系统土壤有机碳储量、碳封存速率和土壤总氮与其在土著占优势的3类生态系统（裸地、海三棱藨草、芦苇）中的差异，结果表明互花米草入侵的生态系统，其土壤有机碳储量高于裸地和海三棱藨草生态系统，却低于芦苇生态系统。

In addition,exotic C4 plant Spartina alterniflora is rapidly invading the salt marshes in the Yangtze River estuary,and displacing the native C3 vascular plants Phragmites australis and Scirpus mariqueter.It is no clear whether the C4 vascular plant invasion has serious impact on food web structure and trophic function of the salt marshes of the Yangtze River estuary.

另外，外来种互花米草正在快速入侵长江口盐沼湿地，这种C_4维管植物入侵将对盐沼湿地食物网及其营养功能会产生什么样的影响也是一个值得探讨的问题。

Extraction and Determination of Total Flavonoids from Root,Stem and Leaf of Suaeda australis

目的单因素试验了不同体积分数的乙醇、料液比、提取温度及提取时间等因素对南方碱蓬叶总黄酮提取率的影响。

OBJECTIVE To investigate the extraction and content of total flavonoids in Suaeda australis leaves.

盐地碱蓬甲型和乙型肝炎联合疫苗

The paper aimed to explore the flavonoids compounds of Suaeda australis contents and its aioxidation activity in vitro.

［目的］探索南方碱蓬叶总黄酮含量及其体外抗氧化活性。

Seasonal variation of the distributions of microorganism in the root-zones of wetland plants (Phragmites australis, Zizania latifolia, Zizania latifolia etc.), the substrate layers of control SSPs, together with the effects of wastewater treatment were studied. The results are as follows: the numbers of microorganisms in the different plant root-zones were different; the purification effects were also different. The number of microorganisms in the substrate of the control plot becomes smaller with increasing depth. The numbers of bacteria in fall were higher than those in the summer for the three plant zones and the control, and the number of fungi and actinomyces in summer was much higher than that in the fall for control. As for fungi and actinomyces in the experimental systems, most of their difference between the summer and fall were not as big as that in the control.

通过对不同季节芦苇、茭白和香蒲等湿地系统植物根区、无植物对照基质微生物分布状况以及净化效果的研究，结果显示：（1）种植不同植物的湿地系统根区微生物数量不同，其湿地净化效果也不同；（2）对照系统微生物的数量随基质深度的增加而递减；（3）季节变化显示湿地系统秋季的细菌总数量比夏季高；但对照系统夏季的真菌和放线菌数量明显高于秋季；（4）湿地系统TP的去除率夏季高于秋季。

" I' d like to get some rough idea about music in the baroque ear, please."

The results showed that the peak latency and pattern of SEPs elicited by electrical needling in LI-l1 and MP were similar. The amplitude of SEPs elicited by electrical needling in LI-l1 was higher than that of MP. There was no obvious SEPs generation when MM was electrical needling.

结果显示，电针刺激曲池穴和其邻近桡侧伸腕长肌运动点诱发性脑电波的波形和波峰时间是类似的，只是穴位的诱发性脑电波波幅较大，而电针刺激非穴位点并没有明显的诱发性脑电位。
