Based on the observation about the ramets characters of predominant clonal rhizome plants from wetland, their modular structure, reproductive allocation and population dynamics were measured and results indicate that:(1) There are 2 or 3 age classes of ramets and 3 types of tubers of Scirpus planiculmis population in terms of four times observation in three years.

对湿地优势根茎植物种群分株构件的年龄结构、构件性状、生殖分配及种群数量动态观测结果表明：(1)紧穗三棱草种群分株3年4次观测有2～3个龄级，球状根茎可划分为3个类型。

There were generally reproductive growth in each age class ramets of Carex kirganica as well as that in Scirpus planiculmis. Furthermore, the more or less of the reproductive allocation was certain and that is the result of reproductive trade-off and the adaptation to their habitats.

长秆苔草和紧穗三棱草各龄级分株均进行有性生殖，并保持一定量的生殖分配大小，是适应生境的生殖策略权衡的结果。12个不同水分梯度生境芦苇生殖分配RA Ⅰ为5.82％～16.31％，生殖生长比率Rrg为10.68%~16.35%，2个生境毛芦苇RAI分别为9.09%和13.98%，生殖生长比率分别为22.07%和1 8.06%。

Methods FromJanuary 1999 to December 2008 the Court treated the 118 cases of neonatal scleredema on gestational age,weight,at birth,the clinical features and prognosis were retrospectively analyzed,and the etiology of conduct before and after the five Comparative analysis of the year.

The optimal harvest time,preserving the green,boiling and technique of preserving the brittleness of Mongolia Scorzonera was studied.

研究了蒙古鸦葱的采收时机，护绿、烫漂和保脆技术，实验表明：选择叶龄在18~20d采收，在浓度为0.2%的稀碱溶液中浸泡30min保绿，烫漂温度98℃、时间叶柄1.5min、叶片0.5min，在烫漂液中加入0.15%的氯化钙保脆等措施，解决了产品速冻时的褪色、质地变软等问题。

In Wistar rats, latent period of a-wave in scotopic rod response after 1-week transplantation was shorten (P.05); and latent period of a-wave in scotopic rod response after 2-week transplantation was prolonged (P.05); while latent period of b-wave in scotopic maximum response after 1-week transplantation was shorten (P.05). In RCS rats, amplitude of a-wave in scotopic rod response and photopic response after 4-week transplantation was increased (PO.05); while latent period of a-wave in scotopic rod response after 4-week transplantation was shorten (PO.05).Conclusion 1. At the age of 3 months, photoreceptors of the RCS rat degenerated completely, which leaded to the reduction of amplitudes of a-wave and b-wave.
