有四种

Begonia pulvinifera is similar to B. wangii T. T. Yü, differing in the lower surface of the leaf being pale green; petiole with a reddish brown swollen base; tepals obtuse; tepals of staminate flowers 4; tepals of carpellate flowers 3 and ovary with axile placentation throughout. Begonia pulvinifera also resembles B. cavaleriei Lév., but is distinguishable by the narrower leaf; pulvinate petiole; stipules triangular with apex acuminate or cuspidate; and ovate bracts with apex acute or acuminate.

objective effects of plant tannins,chebulinic acid and tellimagrandin i on chemically induced hemoglobin synthesis in k562 cells were investigated.methods the hemoglobin synthesis situation was assayed with benzidine staining.erythroid antigens glycophorin a expression on the surface of k562 cells was labeled by direct immunofluorescence using fluorescein isothiocyanate-conjugated anti-gpa antibodies.then flow cytometric analysis was performed to detect gpa expression levels on surface of the cells.results both chebulinic acid and tellimagrandin i could inhibit the hemoglobin synthesis of butyric acid and hemin-treated k562 cells in a concentration-dependant manner.however,the ba-induced k562 cells were more sensitive to two tannins than heroin-induced cells.conclusion chebulinic acid and tellimagrandin i have inhibitory effect on the erythroid differentiation.

目的 研究可水解单宁诃子酸和特里马素i对氯化高铁血红素和丁酸钠诱导k562细胞红系分化的影响。方法四甲基偶氮噻唑蓝法分析诃子酸和特里马素i对k562细胞生长的影响，联苯胺染色法检测血红蛋白合成情况，应用免疫荧光和流式细胞术检测血型糖蛋白a在细胞表面的表达。结果诃子酸和特里马素i在0.04～0.09？mmol／l浓度下均可显著抑制k562细胞的生长增殖。2种单宁化合物(0.002～0.01？mmol／l)可显著抑制丁酸钠诱导的k562细胞血红蛋白合成，2种单宁化合物(0.01～0.05？mmol／l)还可显著抑制氯化高铁血红素诱导的血红蛋白合成，特里马素i(0.01？mmol／l)还抑制丁酸钠诱导的gpa在细胞表面表达。结论诃子酸和特里马素i对红系分化有抑制作用。

As an experiential mode, Consociational Democracy points to four European countries (Austria, Belgium, Holland, Switzerland) and other developing countries(Luxemburg, Lebanon, Malaysia, etc) in some period in history. As an normative mode, it provides new norm for The Third World Countries. Its applicability depends on many favorable, unfavorable and uncertain factors.

作为一种经验模式，结盟民主主要是指奥地利、比利时、荷兰、瑞士四个欧洲国家以及卢森堡、黎巴嫩、马来西亚等发展中国家，且这些国家都有特定历史时段的限定；作为一种规范模式，结盟民主为第三世界发展中国家的政治发展提供了新的可供参考的模式，结盟民主在第三世界国家的适用性取决于多种有利、不利的乃至不确定性的因素。

Our results suggested that the channel contains two of each subunit and the stoichiometry is apt to 2:2 if hetermeric ASIC channel is a tetramer,while the assembly of ASICs is random,the stoichiometry is not fixed(2:1 and 1:2 coexist)if hetermeric ASIC channel is a trimer.This study provided interesting new data supporting the occurrence of the homomeric and heteromeric assembly of ASICs.

另外，我们还对ASIC异聚体的分子比情况进行了初步的探讨，结果发现如果所形成的ASICs异聚体通道是四聚体，那么每种亚单位有两个，分子比倾向于2∶2；如果是三聚体，则提示ASICs的装配是随意的，分子比是不固定的，2∶1和1∶2这两种情况都存在。

本文第四章研制设计了一包含海洋表面边界层和大气辐合反馈过程的热带太平洋海气耦合异常模式，进而利用该模式对ENSO循环进行了较为真实的模拟，通过对模式ENSO循环的演变特征及其形成机制的细致分析，建立了-ENSO循环的非线性分析模式，并提出了ENSO循环形成的一种更为客观的理论，指出：1）和观测事实类似，模式ENSO循环确实涉及了三种主要时间尺度过程即LF、QB和AC，其中LF为3-4年主周期振荡，QB占总方差10～20%；2）ENSO循环的正反馈机制是不稳定海气相互作用过程，且这一不稳定过程的发展在暖态中明显强于冷态；3）ENSO循环的负反馈机制在冷暖态中表现不同，在冷态消亡过程中，这种负反馈过程主要表现为西边界反射产生的时滞效应，但在暖态消亡过程中不存在类似的时滞效应，其负反馈过程主要表现为在海气耦合不稳定充分发展时伴随的赤道两侧冷水上翻过程的加强以及非线性过程的衰减作用抑制了不稳定的发展并最终使得系统回复至冷态；4）ENSO循环的3-4年主周期振荡是一非线性系统的自激振荡现象，其形成是线性系统的本征模即准两年振荡通过非线性机制产生的周期加倍所致，其中&单向性&大气辐合反馈加热过程对其形成至关重要；5）虽然年循环过程对ENSO循环形成没有本质影响，但它可明显影响ENSO循环的具体振幅和位相，使得ENSO对季节循环有明显的&锁相&特征，并且也使得ENSO循环在振幅大小和时间长短方面呈现出明显的不规则性。

N-substituded thioacridones with five different structures were synthesized via a route involving Ull-man reaction, cyclization, N-alkylation and sulfurization. The structures of each thioacridone were identified with IR and MS. The results from UV-spectrophotometry show that the five N-alkythioacridones all have stronger absorption in the visible light region.

采用乌尔曼反应、酸催化环化、N-烷基化和硫代化四步反应路线合成了5种不同结构的N-取代硫代吖啶酮，利用IR和MS分析手段表征了其结构，UV分光光度计的测定结果表明5种硫代吖啶酮在可见光区都有较强的吸收。

Prominence a wide variety of shapes and movement characteristics, in general can be divided into four categories:(1) quiet prominence, change is slow, longer life expectancy, up to the number, and with the presence of sunspots related to sunspots for a long time, it is also a little more;(2) the activities of prominence, from a quiet prominence changes years, the movement is faster, but lower than the sun's surface escape velocity, so mostly circular, the material eventually thrown off the plane back to Japan;(3) the outbreak of prominence, activities of the most intense one, and sometimes velocity can exceed the Sun the surface escape velocity, reaching 100 km D seconds, or even higher altitudes of up to one million kilometers, 20,000 kilometers thick;(4) crown-shaped prominence, looks like clouds, is a rather exceptional prominence.

日珥有各种各样的形状和运动特征，大体上可分为四类：（1）宁静日珥，变化缓慢，寿命较长，可达数目，并与黑子的存在有关，黑子多时，它也多一些；（2）活动日珥，由宁静日珥变化而来，运动速度较快，但低于太阳表面逃逸速度，因此多为环形，抛出的物质最终仍落回日面；（3）爆发日珥，活动最激烈的一种，有时运动速度可超过太阳表面逃逸速度，达100公里D秒，甚至更高，高度可达上百万公里，厚达2万公里；（4）冕形日珥，貌似浮云，是一种比较特殊的日珥。

ANALOGIES are often drawn between the fields of computer science and biology. The information-processing abilities of DNA are a form of natural molecular computing, and computer viruses leap from machine to machine in ways reminiscent of their disease-causing namesakes. At the International Solid-State Circuits Conference in San Francisco this week, a trio of mighty information-technology firms—Sony, Toshiba and IBM—pushed the analogy a little further. They unveiled a much anticipated new computer chip, four years in the making, the very name of which is a biological metaphor: the Cell.

人们经常把计算机科学和生物学进行类比，DNA的信息处理能力是一种自然分子的计算形式，而计算机病毒则让人想起致病性生物病毒，从一台机子感染另一台机子，而这个星期，信息技术的三巨头——索尼、东芝和IBM在旧金山召开的国际晶体管集成电路会议上，把两者间的这种类比作了进一步的推进，他们披露了一种已经研制了四年的、非常有希望的新型计算机芯片，这种芯片的名字来自生物学：细胞。

This paper is divided into five parts: the first part focuses on the currentsituation of research, process of his thoughts and his determination to put it to practice.Thought this part, we can understand the background of his constitutional philosophy;In the second part, We recognize his ideological foundation, describe the awarenessand understanding of his culture about East and West, research his background of thecultures about East and West; In the third part, the writer discuss the history ofevolution about Zhang Junmai constitutional philosophy, describe the process, that isfrom Eucken's philosophy to kant's philosophy. In this process, we understand therole and significance of Zhang Junmai constitutional philosophy in building ademocratic constitutional government; Part IV , in which the writer describes thecharacteristics of Zhang Junmai constitutional philosophy, is important; In the end, thewriter thinks that Zhang Junmai political appeal hadn't achieved at the ideal result thathe expected, but, there were some reasonable factors contained in his thoughts, thatwhat we shouldn't be abandoned but be utilized and developed when constructing themodern nation.
