Results: ApoD was observed positively expressed in type2 astrocytes and oligodendrocytes from O2A lineage, while it was not expressed in type1 astrocytes from T1A lineage. Accordingly, we can verify the phenomenon found in the study of T1A and T2A gene different expression profile that ApoD mRNA was highly expressed in T2A and lowly expressed in T1A. Conclusion: It can be concluded that lipid metabolism related genes such as ApoD play important roles in the generation and differentiation of O2A lineage, which closely correlate with internal mechanism of lipid metabolism in the brain and myelogenesis.［Key words］astrocyte(T1A, T2A); oligodendrocyte; O2A lineage; apolipoproteinApoD

Hong Young YAN pointed out, ibid., squids and octopi are the two major cases of cephalopod. Squids are found everywhere in the five oceans, and never observed as endangered under human's mass hunting and the natural enemies' threat, which means they must be in possession of fine "sense" to protect themselves from dangerous environment.

严宏洋指出，乌贼和章鱼是头足类动物最具代表性的两大族群，乌贼分布全球五大洋，且在人类大量猎补及天敌捕食的情况下仍未显濒绝，显示它们应有优良的「感觉系统」，能在危险的环境压力下繁衍无碍。

Through seawater pCO_2 time series observations along with the surface water chemistry, we observed significant diurnal changes of surface pCO_2 ranging from -10μatm in the oligotrophic SCS, 50-150 uatm in Xiamen Bay and Shenhu Bay, up to as high as 600μatm in the coral reef system at Xisha Islands. Processes that modulate the pCO_2 diurnal variations are significantly different between sites, which can be grouped into three categories: temperature control, tide / current control and biological control.

我们的实验结果表明，所有观测区域均表现出显著的pCO_2周日变化，变化幅度从-10μatm到600μatm不等，其中，南海北部寡营养盐开阔海域的pCO_2变化幅度约为10μatm，以厦门湾、深沪湾为代表的海湾河口区域的pCO_2变化幅度为50-150μatm，而西沙群岛珊瑚礁生态系统的pCO_2的周日变化幅度高达600μatm以上。

the morphologic and hormonal changes of the ovarium in the dehydroeplandrosterone-induced rat PCOS model were similar to those of the patients with PCOS,and the insulin resistance was observed. It was proved to be a ideal PCOS amimal model.Key words DHEA;PCOS; Animal model.

DHEA诱导SD幼年雌性大鼠PCOS动物模型卵巢病理改变及血内分泌改变与PCOS病人相似，并存在胰岛素抵抗现象，是较理想的PCOS模型。

It have been observed that oxonium ion reacted with water more easily than with THF. So water could be used as ceasing reagent to control the molecular weight of the polymer.

本文还对四氢呋喃、环氧丁烷和环氧乙烷阳离子开环聚合反应中，分子内尾咬、扩环这一典型的副反应进行了理论研究。

We found out one kind of new orange-red long afterglow material La2O2S: Eu3+, Mg, Zr.2 In the phosphor Gd2O2S, Mg, Ti which was prepared by high-temperature solid-state method, the orange afterglow phenomenon can be seen after illuminated with UV light.3 Using the high-temperature solid-state method, Gadolinium oxysulfide phosphors doped with rare earth ions were synthesized. We can observe the red or orange phosphorescence in Gd2O2S doped with Eu3+, Sm3+, Tm3+, Yb3+, Dy3+, Er3+, Nd3+or Ho3+. This is a new result of the long afterglow phosphors research.4 Using the microwave radiation method, the new Sm3+ doped gadolinium oxysulfide phosphor, which has the orange-red long afterglow emission after illuminated with UV light or visible light, was synthesized for the first time.5 In fluorescent materials YOX doped with europium ions, the long afterglow phenomenon wasnt observed but the blue luminescence of Eu2+ and red luminescence of Eu3+ are simultaneously examined. This is a new result of the valence stability and change of Eu2+ in yttrium oxyhalide .We systematically studied the effects of the host, addition agents and reaction atmosphere on the valence change and fluorescence property of europium ions.

经过系统的研究总结得到以下的结论与成果： 1采用高温固相反应法合成了一系列稀土离子掺杂的硫氧化镧发光粉，发现了该体系中Eu~(3+)的长余辉发光，从而得到一种迄今未见文献报道的红色长余辉发光材料：La_2O_2S：Eu~(3+)，Mg，Zr； 2在Gd_2O_2S，Mg，Ti磷光粉中观察到橙色的长余辉发光现象； 3采用高温固相反应法合成了一系列稀土离子掺杂的硫氧化钆磷光粉，在掺杂Eu~(3+)、Sm~(3+)、Tm~(3+)、Yb~(3+)、Dy~(3+)、Er~(3+)、Nd~(3+)、Ho~(3+)的Gd_2O_2S中观察到红色和橙色长余辉发光； 4首次采用微波法合成了Gd_2O_2S：Sm~(3+)，Mg，Ti磷光粉，该磷光粉经紫外或可见光激发后呈现明显的橙红色长余辉发光； 5在YOX中同时观察到Eu~(2+)和Eu~(3+)的发射，系统研究了基质、添加剂及反应气氛对Eu价态和发光的影响。

It is also suggested that the correlations between pollen-ovule ratio and pollen size , and ovule size should be accounted for in terms of sex allocation theory.
