Sessile spikelet lanceolate, 4–5 × 1.2–1.4 mm; lower glume leathery with expanded rounded flanks below middle, herbaceous, strongly veined and sharply 2-keeled above, glabrous or villous, keels usually winged, apex 2-toothed; upper glume attenuate into mucro or awnlet to 2 mm; awn of upper lemma 1.2–1.5 cm. Pedicelled spikelet laterally compressed, similar to sessile, upper lemma awned.

无梗小穗披针形， 4-5 * 1.2-1.4 毫米；下部颖片革质具膨大圆形侧面中间以下，草质，龙骨状的脉粗壮和锐的2在上面，上面颖片渐狭窄成为短尖头或awnlet到2毫米；上面外稃的芒类似于无柄，上面的外稃具芒的1.2-1.5 厘米Pedicelled小穗侧面压扁。

At the same time, due to 2~1S_0、 3_1S_0 are the radical excitations of 1~1S_0,we can use Regge trajectory on the (n,M~2)-plane with the approximate same slope to describe the mass of isoscalar of 3~1S_0 nonet (1926MeV). The two results derive from different ways are approximate. 2 The mass of the isodoublet of 2~3S_1 nonet is analyzed in the quarkonium-quarkonium mixing scheme, the results (1584±16.7MeV) is far from the K~*(1410)(1414±15MeV). 3 Based on "glueball dominance" picture, we establish glueball-meson mass relations. For the 2~ glueball mass and 4~ glueball mass used as input parameters, these relations predict the mass of isoscalar of 1~3F_4(4~)(2076±19.66MeV).

的质量(1900±12MeV)；同时考虑到2~1S_0、3~1S_0为1~1S_0的径向激发态，在(n，M~2)雷吉轨迹图中应该具有近似相同的斜率，利用雷吉轨迹可以得到其对应质量为(1926MeV)，两种方法得到了两个十分自洽的结果。2在介子—介子混合框架下，对2~3S_1介子九重态中同位旋二重态的质量给出估计，得到(1584±16.7MeV)，这个结果相对于K~*(1410)=1414±15MeV有较大的偏离。3在胶球为主的图像下，利用介子—胶球质量关系，选择2~与4~胶球的质量作为输入参数，我们得到1~3F_44~(介子九重态中同位旋标量态？

According to the observation experiment at the Jiufeng station where there is smaller environment noise, the conclusions are drawn as follows.In the normal atmosphere, the observed value is about 500×10-5ms-2, which is greater than theoretical value about 30×10-5ms-2, and if in the low vacuum, the observational error about 2.3×10-5ms-2 is generated. The vacuum maintaining system in falling room can not work normally, which will yield 0.1~4.1×10-5ms-2 error to the gravimetric observation. In the case of that the measurement is in the stable geological conditions and the smaller environment noise, the action of vibration isolating spring is not obvious, but it yields greater effects on measurement accuracy.

通过在环境干扰较小的九峰站观测实验，得到如下结论：在正常大气压状态下所观测到的空气阻力影响约500×10-5ms-2，比理论估算值大近30×10-5ms-2，若在低真空状态测量空气阻力也将产生2.3×10-5ms-2观测误差；落体室真空度维持系统工作不正常，空气阻力也将对重力观测造成0.1~4.1×10-5ms-2的观测误差；在地质条件比较稳定，环境震动干扰较小的基墩上测量，隔震弹簧的作用对观测结果影响不明显，但对测量精度影响较大。

Two kinds of dsDNA intercalating fluorescent dyes, [Ru2]2+(phen = 1,10-phenanlinthroline; dppz = dipyrido [3,2-a:2',3'-c] phenazine) and BOBO-3 2,2\'-1,3-propanediylbis[(dimethyliminio-3,1-propanediyl -1(4H)-pyridinyl-4-ylidenemethy-lidynebis[3-methyl]-benzothiazoe were employed in this chapter, and two non-covalent labeled fluorescence sensing systems for thrombin determination were successfully developed and compared based on its 29-mer aptamer.

Base on above studies, some conclusions were obtained as follows:(1) ore-forming background of the studied ferromanganese crusts are mainly controlled by intensity of Antarctic Bottom Waters and variations of material source;(2) it is confirmed that the ferromanganese crusts are mainly hydrogenetic and their composition are affected by volcanic and continental material simultaneously; there are no obvious phosphatization reconstruction and element reaction occurred in them, so they have important paleoceanological significance;(3) from researches on element occurrence modes in the new-type ferromanganese crusts and the lying sediments, it is proposed that there is no great biological affection on the crusts formation and their composition mainly came from the adsorptive action of the ferromanganese oxides in them;(4) two major types of ore-controlling factors are identified through compilation of ore-controlling factors, which are geological and oceanic factors;(5) considering the long-term variation trends of the crusts composition, combing the U-series and 10Be isotope dating results, it is proposed that the ore-forming processes of ferromanganese crusts in the studied areas can be divided into three major stages (5.6~2.8 Ma, 2.8~2.7 Ma and since 2.7 Ma), and then the activities of AABW since the Late Miocene, changes of input flux coming from volcanic and continental material are confirmed.

通过研究，得出如下结论：(1)研究区铁锰结壳的成矿背景主要受控于南极底流强弱及物源供给的变化；(2)证实铁锰结壳主要为水成成因，同时其物质组成也受一定程度的火山和陆源物质的影响；结壳自形成以来没有遭受到明显的磷酸盐化等成岩后期改造和元素再迁移，具有重要的古海洋学意义；(3)通过新型铁锰结壳及下伏沉积物元素赋存状态的研究，认为生物作用对研究区结壳的形成并没有很大的直接影响，其物质成分主要来自于结壳中铁锰氧化物的吸附作用；(4)在控矿要素的研究中，归纳出了地质与海洋两大类结壳控矿要素；(5)根据结壳成分长周期变化趋势，结合铀系和10Be测年结果，将研究区结壳的形成过程划分为三个主要阶段(5.6~2.8 Ma，2.8~2.7 Ma和2.7 Ma以来)，并确定了晚中新世以来研究区南极底流的活动情况、火山和大陆来源物质输入量的变化。

SW480 and SW620 cells were also used to study the gene regulation with high carbohydrate intake, where it was shown that during glycolysis eight genes, HK1 (nuclear gene encoding mitochondrial protein, transcript variant 1), GPI, GAPD (glyceraldehyde-3-phosphate dehydrogenase), PGK1 (phosphoglycerate kinase 1), PGK2 (phosphoglycerate kinase 2), ENO2 (enolase 2), PKM2 (pyruvate kinase, muscle, transcript variant 2) and GLUT1 (facilitated glucose transporter, member 1) are over-expressed. In our study, we also found that during hypoxia of cancer tissues the resulting up-regulation of HIF-2α(hypoxia-inducible factor 2, alpha subunit) would in turn up-regulate the GLU1 gene, further activating glycolysis.

另一方面，在高碳水化合物的调控研究上，吾人也利用SW480和SW620细胞株分析证实醣解水解活化过程中，其六碳醣激酶-1(HK1)、葡萄糖磷酸异构酶、3-磷酸甘油醛脱氢酶、磷酸甘油酸激酶-1(PGK1)、磷酸甘油酸激酶-2(PGK2)、烯醇酶-2(ENO2)、丙酮酸激酶-2(PKM2)以及葡萄糖输送蛋白-1(GLUT1)等共有8个基因是连续上升的过度表现；此外，吾人也发现当癌细胞在缺氧的组织中，其缺氧转录子-2α基因(HIF-2α)表现上升后，会活化GLU1基因上升，进一步活化醣解代谢的进行。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
