Unpiloted and looking rather like a large, fat fighter aeroplane , it is launched from a converted Boeing 747. Having released the upper stage at about one half satellite speed, the rocket-powered lower stage glides back to base and lands

X-34无人驾驶，外观更像一个庞大的战斗机，它从一个经过改造的波音747飞机上发射，当以约为卫星的一半速度释放上部一级火箭后，采用火箭发动机驱动的下部一级火箭就滑降回基地并着陆。

The most senior tranches, rated AAA, received the lowest returns, and then they went down the line to lower ratings and finally to the unrated "equity" tranches at the bottom.

最好的那些"块块"被定级三A，收益率是最低的，评级较低的收益率就略高，一级一级排到底。〔因为评级低的"资产"风险大，所以"价格"就高，收益率就高

The result showed that the oxidation reaction of abietic acid is first-order reaction during the initial period but then isn't first-order reaction because of oxidant film.

实验结果表明，枞酸氧化反应动力学在初期阶段呈表观一级，后期受氧化膜影响不呈表观一级。

The experimental results showed that the aquation of JM216 follows the pseudo-first-order- rate law, of which the observed-rate constant kobs is 5.0×1.0-6min-1and the half life period t1/2 is 96.25 days at 37℃.

柘林湖位于修河中部，地跨永修、武宁两县，湖区面积308平方公里，有997座大小不一、形态各异的岛屿，被誉为&一级空气、一级水质的休闲度假乐园。&

Path analysis showed internodal distance,first lateral branch number and whole-plant leaf weight with a significant positive effect on vindoline content (P.05), with path coefficients of 0.959, 0.716 and 0.431 respectively, which suggests that internodal distance, first lateral branch number and whole-plant leaf weight are the important factors in breeding C.

通径分析结果表明，长春花的主要农艺性状中，节间距、一级侧枝数和全株叶片重对文多灵含量的正影响达到了显著水平(P.05)，通径系数分别为0.959、0.716和。431，说明节间距、一级侧枝数和全株叶片重可以作为高含量文多灵长春花品种选育的重要参考指标。

Results showed that the kinetics of photocatalytic degradation of ethylene by TiO2/ACF desoposited Pt in the simulated cold storage environment for horticultural products could be described using the pseudo first-order equation. The prepared TiO2/ACF-Pt, in the process of which Pt was initially deposited on the surface of ACF and then TiO2 was coated, would promote the activity of ethylene decomposing. When ion sputtering time was 60 seconds (Pt/Ti atomic concentration ratio was 0.112), the apparent rate constant of the reaction of TiO2/ACF-Pt was 1.16 times as much as that of TiO2/ACF. The micrographic structure of ACF was not damaged and an excessive porous structure, which was contributive to absorbing the diluted ethylene, was obtained by the way of ion sputtering Pt.

结果表明：在模拟园艺产品冷藏环境中，TiO2 /ACF-Pt光催化降解乙烯的动力学可用表观一级速率方程来描述；ACF表面先溅射沉积Pt，再进行TiO2附着方案，能提高降解乙烯的能力，当溅射时间为60 s（Pt/Ti原子浓度比为0.112）时，表观一级速率常数是未溅射Pt的1.16倍；TiO2/ACF-Pt的制备方法，对ACF形貌结构没有破坏，并能得到有利于对微量乙烯的吸附的多孔结构。

In studying gobies we noticed that only the largest two individuals, a male and female, had breeding rights within the group," explains Marian Wrong."All other group members are nonbreeding females, each being 5-10% smaller than its next largest competitor.

在对沙鱼的研究中我们发现，只有两个大的个体——一雄一雌在种群中有繁殖的权利，&玛丽安·翁这样解释说，&其他所有群体成员都是不能繁殖的雌性，每一级都比其上一级小5%-10%。

Immunoelectron microscopic examination revealed that mGluR5 was prominently located in some neuronal somata and a lot of dendrites within the superficial layers of the spinal dorsal horn. Some dendrites containing mGluR5 constituted synaptic glomeruli with the terminals exhibiting the morphological characteristics of primary afferent C fiber. The ultrastructural features indicated that mGluR5 in the dorsal horn of the spinal cord may prominently work as a postsynaptical receptor to mediate or modulate the function of glutamate in the primary sensory transmission, including the nociceptive transmission.

免疫电镜研究显示，在脊髓背角浅层内，mGluR5主要定位在部分神经元胞体和大量树突内，并常见部分含mGluR5的树突与具有一级传入C纤维终末形态特征的轴突终末构成突触小球。mGluR5在脊髓背角浅层内的超微定位特征表明，脊髓背角内的mGluR5可能主要作为突触后受体介导或调节谷氨酸传递一级感觉的功能。
