To further reveal the structure of monocotyledon lignin, carbon 13 enrichment of specific carbons of rice stalk lignin was achieved by feeding coniferin [α 13 C], coniferin [β 13 C] and coniferin [γ 13 C] into an internode cavity of the stalk of a growing rice plant Oryza sativa L.

为了进一步了解单子叶植物的木素，向生长中的水稻(OryzasativaL 。)茎秆节间的腔体分别注入在侧链α、β、γ位带13 C标记的松柏醇葡萄糖甙，得到侧链带13 C标记的稻秆木素。

Methods Six cadaveric lumbar vertebrae were harvested and evaluated with dual-energy x-ray absorptiometry and quantitative computed tomography to assess bone mineral density. Matched, polyaxial pedicle screws were then randomly assigned by side and placed using the Magerl, Krag or caudad trajectory technique assisted by Iso-C 3D scan and 3D navigation system. Cyclic loading tests were performed with a maximum 250 N load at 3 Hz up to 30000 cycles while recording load and displacement. Stiffness quotients were calculated it comparison.

从尸体中获取6节腰椎椎体经DEXA和QCT检测骨密度值，证实为骨质疏松后在计算机导航下按随机分组的方法向12个椎弓根中置人不同方向的椎弓根螺钉，使用MTS-858生物力学仪脊柱力学测试平台进行±250N的循环负荷疲劳测试，记录负荷循环中的螺钉位移，计算系统的刚度系数并进行对比分析。

For bulk lamella-forming diblock copolymers, perpendicular lamellae and concentric lamellae spontaneously form under the neutral and strongly preferential surface, respectively. When the surface preference is relatively weak, novel structures such as parallel lamellae, helices and catenarian structures are observed.

对体相形成层状相的双嵌段共聚物，我们发现在中性孔壁下共聚物自组装形成垂直于孔壁的垂直层结构，在强选择性孔壁下形成一系列的同心层结构，而在弱选择性孔壁下形成平行于孔轴的平行层、螺旋和链节等新奇结构。

Some explants were collected indirectly from epicormic shoots which sprouted from branches of plus trees raised on wetting sands, and some were from grafts of plus trees when their scions were grafted onto seedlings for 3 months.

取这些获选表型母树之桉穗、或剪取母树的粗枝在湿砂床上培养萌出之簇生芽、或嫁接成功之接穗新长出枝条上的顶芽或带腋芽的节为培植体，进行试管内培养。

BrdU labeling indicated that the positive cells in the lateral ganglionic eminence migrated in a similar way to those in control group 6 h following Xray irradiation, the positive cells were observed to be around the cystic cavities in cortexstriatum 2 days later and migrated to the ventral cortical plate 4 days later.

BrdU标识显示腹侧端脑的外侧节隆起的神经细胞移动类似于正常对照组，2 d后阳性细胞分布在皮质纹状体区形成的空洞周围，4 d后移动到腹侧皮质板。

The main girder is designed to apply C60 pumpable high performance concrete with set retarding, high early strength and good volume stability to avoid cracking and meet the time requirement for the project.

主梁混凝土设计为C60泵送混凝土，采用8米挂篮悬浇工艺施工，混凝土技术要求很高：不仅坍落度损失要小、易于泵送，而且还要具有较长的缓凝时间，以保证一个梁段一次浇筑完成；有较高的早期强度，可在3至4天内进行预应力张拉，以缩短节段悬浇周期；有较好的体积稳定性，以避免梁体产生有害变形和开裂。

Stems of Ipomoea batatasLam in vitro were cultured on MS rhizogenic base medium. ifferent combinations of CO2 concentration and photosynthetic photo flux density in microenvironment were controlled and recorded by special system. The plantlets getting the highest net photosynthetic rate were treated by the combination of (Ci=8 720 μmol mol-1,PPFD=250 μ mol m-2 s-1). Then, the plantlets had been further cultured for 21 d in such microenvironment.

以新兴蔬菜叶用甘薯组织培养苗的茎节段作为外植体，用MS低糖、无激素培养基进行生根培养，设置不同的CO2浓度和光合光量子通量密度对组培植株进行环境调控处理，获得小植株净光合速率最高的处理组合=8 720 μmol mol-1， 250 μmol m-2 s-1），并在此组合下继续培养21 d。

However, when trans-4-aryl-3-buten-2-ones were taken as the substrates, the electron-rich but less sterically hindered ligand 9c gives the best results (up to 96.4 % ee) with highly catalytic activity.

而富电子但空间位阻小的配体9c对亚节基丙酮类底物获得最好的结果(%。4%ee)，同时还表现了最好的化学活性。

The results indicate there are different salinity tolerances during development, and following the increasing tendency as nauplii copepodites adults.

结果显示不同发育期的个体具有不同的生理耐盐范围，耐盐能力随著个体发育呈无节幼体＜桡足幼体＜成体的趋势增长。
