This paper has studied the physiological and biochemical changes during the period of forming strong buds of tree peony, and expect to provide academic basis for extending its view value and economic benefit . The main results are as the following:1 Under the field condition, Characteristics of photosynthesis of tree peony are very regular. From before blooming to the prophase of abducting buds that after blooming ,that is April,May and June,the net photosynthetic rate of tree peony is higher than the other period .It indicates that this period is very important for accumulating photosynthetic products of tree peony . So, if we want to get quality flower of tree peony ,it is very important to strengthen the management of tree peony cultivation and to ensure provide the fertilizer and water.2 From the middle ten days of June, with the time elapsing and with the environment conditions worsening, the characteristics of photosynthesis of tree peony decline deeply. But it is different among different tree peony breeds. For example , cv. Wu Long Peng Sheng can also has higher net photosynthetic rate, it indicates that cv. Wu Long Peng Sheng is super than the other two tree peony breeds when adapting the environment conditions and cv. Wu Long Peng Sheng has wide prospect to extend .3 The main factors of effecting the characteristics of photosynthesis are stomatal factor and non-stomatal factor ,that is the ability of photosynthesis of leaf cells. Under the environment of high light intensity in midsummer, if overshadow tree peony properly, then it can slow the declining of chlorophyll content, and increase the net photosynthetic rate and benefit for the accumulating of photosynthetic products.4 The content of soluble sugar in the root of tree peony is the highest among different organs during the period of forming strong buds . According to analyse ,we believe that the soluble sugar will compose starch then, and provide the solid base of material for the growth and development next year. It provide us strong academic basis of adopting the method of cultivating root and protecting root under thefield environment conditions .In other words ,it will help to increase the health level of the whole plant of tree peony and will be beneficial to forming quality tree peony flower if we strengthen the management of root. 5 To tree peony, the endogenesis hormone is important for its growth and development .In the prophase ,that is about the blooming of tree peony and the mid-summer ,IAA and ZR contents are higher and GA content is lower and its changes are very little, and the content of ABA is decreasing . This indicates that IAA and ZR act the important promote function for growth and development of tree peony in this period, and the function of GA is not important. Bur in the period of anniversary senescence of tree peony , the content of IAA and ZR begin to decrease ,while the ABA content has a certain rebound .T

本研究对几个牡丹品种壮芽形成过程中的某些生理生化变化做了研究，以期了解牡丹生长发育过程中生理生化的变化规律，探讨大田栽培条件下提高牡丹花质量的栽培措施和管理技术，为提高牡丹的观赏价值和经济效益提供理论依据，结果如下：1 大田栽培条件下，牡丹光合特性在生长发育过程中表现出极强的规律性，牡丹各品种的光合速率从牡丹开花前，到牡丹花谢后的花芽诱导期前期（6月10日之前），也就是在4、5、6月份，各牡丹品种的净光合速率相对与其他时间都维持在比较高的水平，这说明，在这段时间，是牡丹光合产物积累的重要时期，因此，要保证得到高质量的牡丹花，在这段时间加强对牡丹的栽培管理，保证这个时期的肥水供应十分重要。2 从6月中旬后，随时间的推移，环境条件的恶化，牡丹的光合性能剧烈下降，但是不同牡丹品种间仍有差异，比如，乌龙捧盛仍可维持较高的光合水平，这说明了乌龙捧盛这个牡丹品种对于环境的适应性较之其他牡丹品种高，有着广泛的推广前景。3 影响牡丹光合性能的主要因子是气孔因素和非气孔因素即叶肉细胞的光合能力，在盛夏高温高光强的环境条件下，对牡丹进行适当遮荫，能缓解牡丹叶绿素水平的下降，适当提高Pn，有利于光合产物的积累。4 可溶性糖在牡丹各品种的壮芽形成过程中，根中可溶性糖的含量在牡丹各部位中始终维持最高水平，分析认为这些可溶性糖在根系中进一步合成淀粉等储藏性物质，为来年牡丹的生长提供雄厚的物质基础，这为我们在大田栽培条件下对牡丹采取养根护根的栽培措施提供了有力的理论依据，即在大田栽培条件下，加强对牡丹根系的管理，有助于提高牡丹整株的健壮程度，有益于形成高质量的牡丹花。5内源激素对牡丹的生长发育调节作用是十分明显的，在前期，即开花前后和盛夏，IAA和ZR含量维持在比较高的水平，GA含量低且变化不明显，ABA含量逐渐降低，说明了IAA和ZR对牡丹在这段时间内的生长发育起到重要的促进作用，GA的作用不是很明显，ABA可能在高温高光强下有明显的升高，也说明了ABA的确有一些促进作用，但是到了牡丹周年衰老期，IAA和ZR的含量开始下降，ABA含量却有了一定程度的反弹，说明了IAA和ZR的作用开始降低，ABA起到了促进衰老的作用

The inward current in OHCs was totally inhibited after the superfusion of 100μmolIL and 200μmo1/L linopirdine respectively. The outward rectifier K(superscript +) current I(subscript K was the dominant K(superscript +) current in the whole cell currents in Deiters' cells. In the presence of 200μmol/L linopirdine, the current was not significantly affected.

在细胞外液中，加入100μmol/L利诺吡啶后，OHCs中的四乙基二乙胺敏感的钾电流峰电流成分被抑制，稳态电流幅值减小，且电流的失活时间常数明显延长；在细胞外液中加入100μmol/L利诺吡吮后，OHCs的内向性钾电流I被完全抑制；而细胞外液中利诺吡啶终浓度为200μmol/L时，Deiters 细胞的外向整流性钾电流幅值无明显变化。

The outward rectifier K+ current current was the dominant K+ current in the whole cell currents in Deiters' cells. In the presence of 200μ M linopirdine, the Ik current was not significantly effected. Our findings demonstrated that the KCNQ heteromeric or homomeric potassium channel may be the molecular basis for the peak outward K+ current and testified that the inward IKn current is mediated by KCNQ potassium channel.

早期急性和慢性排斥反应分别为7.7 ％和0％。3例死亡的原因分别是移植后2周的真菌性动脉瘤；移植后4月的巨细胞病毒感染；移植后2年的肺部感染。25例病人中的余下的22例（ 88 ％）在最后的随访中（一直随访至8年）都很好。

Light microscope and transmission electron microscopy showed that SMMC-7721 cells induced by SAHA had undergone the restorational alteration in morphology and ultrastructure, which were different from those of nontreated cells but were similar to those of normal cells, and the changes were as follows: the cells turned to be flat and spread; the nucleo-cytoplasmic ratio lessened and nuclear shape became rather regular; the number of nucleolus reduced and its volume lessened; euchromatin increased while heterochromatin decreased in nucleus; in the cytoplasm, mitochondria grew in number with relatively consistent structure and well-developed mitochondria cristae; Golgi complex turned to be well-developed and typical; rough endoplasmic reticulum increased. Immunocytochemistry assay showed that the expression of AFP and PCNA were declined significantly. FCM analysis showed SAHA could arrest SMMC-7721 cells in G0/G1 phase, with an accumulation of the cells in G0/G1 phase while a decrease of cells in S phase. Semi-quantitative RT-PCR detection revealed that the expression of p21WAFl mRNA was upregulated remarkably in the cells treated with SAHA.

结果：倒置显微镜和透射电镜观察显示，经SAHA处理的细胞增殖速度显著减慢，细胞体积增大，细胞核较小，形状较为规则，核仁数量减少、体积变小，核内常染色质增多而异染色质减少，核质比例减小，细胞质内线粒体数量增多、线粒体嵴发达，高尔基体较为典型，粗糙型内质网增多，呈现出与正常上皮细胞相似的形态变化；MTT比色法测定结果显示不同浓度(2.5、5.0、7.5、10.0uM)SAHA对SMMC-7721细胞的增殖均有抑制作用，并有明显的剂量依赖和时间依赖关系；免疫细胞化学检测显示SAHA能显著降低PCNA和AFP在SMMC-7721细胞中的表达；流式细胞仪检测结果显示，SMMC-7721细胞经SAHA处理后，G0/G1期细胞明显增加，S期细胞则明显减少，细胞被阻滞于G0/G1期；RT-PCR检测结果表明，SAHA作用12h后SMMC-7721细胞中p21WAF1 mRNA的表达即有增加，24h后更为明显。

By 17:50, the stadium was almost full. The viewers in the front rows suddenly made a tumult and stood up. Agatha and me promptly placed our telescopes to look around the backstage. After 2 or 3 seconds, I found Nakai walking pass the ring path of our side, I tried to search for Takuya at his back. A few seconds later, Takuya's face appeared on the big screen, I found out that he took the opposite direction and had walked quite far ahead that I could only see his back. I found a silver stick in his right hand, I thought it might be a sword, the black suit swang along with his move.

5点50，观众都差不多进场了，看到坐前排的人突然站起来，我跟阿加莎赶紧把望远镜对准后舞台位置寻找，几秒后看到中居走过我们这边通道，再在他后面找拓哉，几秒后他的脸出现在大屏幕上，才知道他走的方向与中居相反，等我发现的时候，已经只能看到远远背影了，那黑衣服随着他身体摆动着，手里拿的那根银色的棍子，会不会是剑呢？

结果显示：3%甘油冷冻解冻后精液的活率、活力(38.54%、52.24%)显著(P.05)高于2%甘油组(15.63%、28.22%)，但3%甘油组顶体完整率(11.55%)显著(P.05)低于2%甘油组(21.71%)。38℃水浴解冻后的精子在39℃培养箱中4h内活率高于0.3，而50℃水浴解冻后1h后的活率低于0.3。

In the producer gas sulfur originates in the gasification uses the coal, mainly by the H2S form existence, gasifies with the coal in the sulfur has 80% to transform H2S approximately to enter the coal gas, if, gasifies with the coal including the sulfur quantity is 1%, after the gasification changes over to in the coal gas to form about H2S approximately 2-3g/Nm3, but professions and so on ceramics, kleit contain the sulfur quantity request to the coal gas are 20-50 mg/Nm3; If in after coal gas H2S burning transforms SO2 is completely about 2.6g/m3, stipulates the SO2 highest emissions density target compared to the country to outdo many.

发生炉煤气中的硫来源于气化用煤，主要以H2S形式存在，气化用煤中的硫约有80％转化成H2S进入煤气，假如，气化用煤的含硫量为1％，气化后转入煤气中形成H2S大约2-3g/Nm3左右，而陶瓷、高岭土等行业对煤气含硫量要求为20-50 mg/Nm3；假如煤气中的H2S燃烧后全部转化成SO2为2.6g/m3左右，比国家规定的SO2的最高排放浓度指标高出许多。
