This time five minutes have passed, the first batch of implementation debarkation flight vehicle group formation, the major part already has mounted this fully was the pothole mist layered planetoid, and inserted difficultly belonged to them, the first serial number was 001 group red war flags; After they land, immediately puts on specially made the universe exposure suit, harbors several big courages, went out the starship; They pull under Farr's leadership in party chief, is putting on the specially made adsorption shoes, is braving the steam which raids intermittently, carries on the tense starship fixed task, sees only universe super all-purpose adhesive which they use to prepare beforehand, clinched the anchor chain acme anchor sticks tightly in, in this planetoid hard gloomy outer covering or the every large or small slit edge, then started immediately for other debarkation group, the clear signal direction and the debarkation location choice as well as the establishment direct work and so on supreme headquarters, facing is being stepped on by them under the foot, huge terror rapid advance this planetoid, they were already growing the universe soldier who most stood out for the humanity!

此时五分钟过去了，第一批实施登陆的飞行器小组编队，绝大部分已经登上了这颗满是坑洞雾气重重的小行星，并艰难地插上了属于他们的，第一面编号为001的小组红色战旗；他们登陆后，就立即穿上特制的宇宙防护服，怀着几大的勇气，走出了星际飞行器；他们在队长拉法尔的带领下，穿着特制的吸附鞋，冒着阵阵袭来的热气，进行紧张的星际飞行器固定任务，只见他们用事先准备好的宇宙超级万能胶，把锚链尖端的锚钩紧紧地粘在了，这颗小行星坚硬灰暗的外壳上或大大小小的缝隙边缘，然后立即开始为其他登陆小组，进行信号指引和登陆场地选择以及建立指挥大本营等工作，面对着被他们踩在脚下，庞大恐怖正急速前进的这颗小行星，他们已经成长为人类最出类拔萃的宇宙战士！

Compared with 810S,the total photosynthetic pigment content of Biao 810S was aabout 50%lower;which was the main cause of the yellow green leaf.2、The spikelet numbers,stigma exsertion rate and flowering time of Biao 810S were same as that of 810S.There were no significant difference of the agronomic traits between the the cross combination which came from the maintainers D100 and R96-1 and the combination from 810S.3、The photosynthetic rate of Biao810S was higher than 810S under strong light and lower under weak light.

叶绿素含量下降是标810S叶片呈淡黄绿叶色的根本原因。2、标810S的颖花数、柱头外露率和开花时间与对照基本相当，与恢复系D100和R96-1配制的杂交组合农艺性状与用810S配制的相应推广组合无明显差异，表明标810S可替代810S应用于两系杂交水稻，其淡黄绿叶色性状可应用于杂交制种田的不育系群体除杂，同时可根据幼苗期淡黄绿叶色性状植株的比例用于鉴定杂交组合中不育系的混杂率。3、弱光条件下标810S的光合速率低于810S，强光条件下标810S光合速率比对照高，且标810S在光强2400μmol·m~(-2)·s~(-1)以下没有光饱和点和"午休"现象。

This study was to evaluate the action mechanisms of 6-BA applyed exteriorly on the growth and chilling resistance of oilseed rape seedlings before or under a low temperature (4℃) stress and resuming growth. Results showed that under low temperature, the oil rapeseed seedling was damaged at a certain extent. 5 mg L~(-1) of 6-BA accelerated the growth of seedlings, controled the chemical matter in cell and protected the stabilization of cell membrane, so 6-BA improved the chilling resistance of seedlings.

通过对低温(4℃)胁迫前、低温胁迫后和恢复生长4d后油菜幼苗的相关生理指标研究发现，低温下油菜幼苗受到一定的伤害，但5mg L~(-1) 6-BA通过促进幼苗生长，调节细胞内化学物质，保护细胞膜的稳定，提高了幼苗抗寒性。

The method is realized by that polyether ether ketone is added into concentrated sulfuric acid to carry out sulfonation reaction, thereby obtaining sulfonated polyether ether ketone, then the sulfonated polyether ether ketone is dissolved in organic solvent, N, N (1)-Carbonyldiimidazole is added to stir for one to three hours, coupling agent is mixed for stirring the reaction for 1.5 to 4 hours, then inorganic crosslinking agent is mixed to react under the temperature of 50 to 80 DEG C. Proton conductors are mixed to continue getting the mixed solution of the sulfonated polyether ether ketone or the inorganic crosslinking agent or proton conductors under the temperature. Finally the proton exchange membrane for a direct methanol fuel cell is obtained by that the mixed solution of the sulfonated polyether ether ketone or the inorganic crosslinking agent or proton conductors is/are processed through membrane forming, drying and exuviation.

该方法首先将聚醚醚酮加入浓硫酸中进行磺化反应得到磺化聚醚醚酮；然后将磺化聚醚醚酮溶于有机溶剂中，加入N，N′-羰基二咪唑搅拌1～3小时后加入偶联剂搅拌反应1.5～4小时，再加入无机交联剂在50～80℃下反应，然后加入质子导体继续在此温度下反应得到磺化聚醚醚酮/无机交联剂/质子导体的混合溶液；最后将磺化聚醚醚酮/无机交联剂/质子导体的混合物溶液成膜，干燥，脱膜即得到所述的直接甲醇燃料电池用质子交换膜。

Comparisons between market performance under auction mechanisms and that under market maker mechanisms are made in terms of liquidity, stability, efficiency and transparency. The comparative results show that certain price formation mechanics integrated with specific market environment can affect market performance. The results of the test that is used to verify the liquidity of security market in China indicate that current price formation mechanics can provide the securities market with better liquidity. But the fixation of the minimum changing price lowers the liquidity of the market factitiously and close call auction mechanisms result in increased price fluctuation and price manipulation. Through the analysis on the competitive strategy of securities market, the objects and principles of the design of price formation mechanisms are established.

本文推导出了竞价机制和市商机制下证券市场的均衡价格，结果表明不同的价格形成机制对资产的真实价格有着不同的反映；从证券市场的流动性、稳定性、有效性和透明度等四个方面分别对竞价机制和做市商机制下的市场绩效进行了比较分析，结果表明一定的价格形成机制和特定的市场环境相结合就会对市场绩效产生不同的影响；通过对我国证券市场的流动性进行实证检验，发现当前我国证券市场价格形成机制能够为市场提供较好的流动性，但固定的最小变动价位人为地降低了市场流动性，并且封闭式的开盘集合竞价导致价格波动加大和市场操纵。

The first special person is the tooth fairy, and the tooth fairy gives you money for your teeth, so it works like this: when you're very young you lose all your teeth, usually one by one, so every time you lose a tooth you put your tooth under your pillow and when you wake up the next day, magically there is money under your pillow, usually it's a silver dollar
