Another new spatial 3-RPS parallel pyramid manipulator mechanism is studied. The principal screws of this mechanism under three different configurations are identified by means of the conic section and the quadric degenerating theory, respectively. The planar conics representing the relations between the pitches of the output twists and the three linear inputs are described, and the three-dimensional distribution of the axes of all the twists with the same pitch is illustrated under each of the configurations.

研究了另一种新的空间三自由度3-RPS并联角台机构，分别用二次曲线和二次曲面分解法识别该机构在三种位形下的主螺旋，绘制了其在每种位形下的输出运动螺旋的节距与输入之间的平面图以及具有相同节距的所有运动螺旋轴线在每种位形下的空间分布的立体图。

It was about 8 years ago. And we started from the notes. I thought the notes were too difficult to learn, because I couldn't make a difference of the minim and the crotchet.But my parents and my teacher were really great, they had patience to teach me how to partition them.

大约是在8年前，那节课讲的是音符，我当时觉得音符特别难学，因为我分不清二分音符和四分音符，但是我的父母和老师对我非常好，他们很耐心的教我如何分辨它们。

The traits of dedifferentiation and redifferentiation of the explants form H. sampsonii show that the calli the stem and leaf usually form buds at its parietal cells. In the presence of auxin, the parenchyma of the leaf gap at the node is initiated firstly, then, develops blastemata that form buds in a cluster on the node without callus. These show that the various parts ofthe herb differ greatly in cell initiation and organ differentiation.

研究元宝草外植体的脱分化和再分化的特点结果表明，茎段和叶片启动形成愈伤组织，其不定芽通常发生在愈伤组织的周边区，茎节叶腋的叶隙薄壁组织在激素的诱导下启动、分裂，不形成愈伤组织而直接器官分化成芽原基，并在节结处产生一圈成簇的不定芽，表明元宝草不同部位的细胞启动及器官分化调控存在差异。

Objective to evaluate the functional recovery of acute spinal cord injuried rats treated with exogenous wnt-3a signal protein administration and to explore its mechanism.methods moderate spinal cord contusion injury was made in 40 adult sprague dawley rats at t10.twenty rats served as contusion controls(group 1).twenty rats were treated with wnt-3a for three days after injury (group 2).the functional recovery of the rats was observed through basso,beattie,bresnahan open field locomotor score.rats were killed at 14 or 28 days after injury,then spinal cords were removed for histopathological examinations,and the expression of the bromodeoxyuridine plus neural cell markers was stained with immunohistochemical method.results rats of two groups receiving a contusive injury recovered substantial function within 1 week.by 28 days,rats in groups 2 scored 7.0 points better on the bbb scores than rats in group 1 group 2=16.94,after 28 days vs.

目的 研究外源性wnt-3a信号蛋白对脊髓损伤的修复作用，并探讨其作用机制。方法取40只成年雌性sd大鼠在t10节段制备适度脊髓挫伤模型。随机从中取20只为损伤对照组(group 1)，另外20只为损伤治疗组(group 2)。脊髓损伤3天后用wnt-3a蛋白治疗。这些大鼠的功能恢复通过basso、beattie、bresnahan开放视野运动评分来观察。这些大鼠分批在损伤后14天或28天被处死，取出损伤节段脊髓用来组织病理学检查，同时用5-溴脱氧尿嘧啶核苷和神经细胞标记物进行免疫组化染色。结果两组大鼠在伤后一周运动功能有明显的恢复。不过，到损伤后28天，我们观察发现，损伤治疗组中的大鼠bbb评分比损伤对照组中的评分高出7.0分左右(group 2∶16.94±1.18，group 1∶9.89±1.29；p.05)，光镜和电镜检查发现wnt-3a蛋白对髓鞘形成和轴突再生有一定的修复效果。

Panicle dense, narrowly oblong in outline, 10–22 cm; branches 2–5 cm, branchlets many, short, pilose in axils; racemes 2–4-noded with 7–11 spikelets, disarticulating at maturity, one spikelet of a pair sessile, the other pedicellate; internodes and pedicels 2–2.5 mm, slender with expanded tips, densely ciliate.

Playing in front of a capacity crowd that featured New Orleans Saints quarterback Drew Brees, the rapper Bow Wow and the retired wrestler Ric Flair, the Hornets did not go quietly. They used a 13-3 run to cut the Spurs' 14-point lead early in the fourth quarter to 81-77 on two free throws by guard Janerro Pargo with 3 minutes 10 seconds left.

在新奥尔良主场天才橄榄球手Drew Brees，Bow Wow 以及退役的摔跤高手Ric Flair的助威中，黄蜂队打得非常之顽强，第四节最后3分10秒，后卫Janerro Parg两罚全中，至此，黄蜂以一波13比3的攻势把比分追近到81比77，此前马刺以14分领先。

Lakers' run to start the second quarter to give them a 15 point cushion at half time.

12--4。湖人队的球员在第二节时打出了一波12--4的小高潮，使得半场分差为15分。

The results showed that (1) compared with conventional N treatment, the N loss of economic N treatment reduced while NUE and N residue in soil improved under water-saving condition;(2) Use efficiency of fertilizer applied as basal fertilizer was higher than that as top-dressing fertilizer under water-saving condition;(3) The fertilizer N residue rate was from 29% to 41%, and 60% of N residue, which distributed in 1m depth soil concentrated in 0～20cm surface layer;(4) In whole growing stage of wheat, fertilizer N hadn't leach to 130cm depth;(5) NUE of economic N treatment under conventional irrigation decreased by 16.6% compared with the same N treatment under water-saving condition.

结果表明，与常规施氮量处理相比，节水灌溉条件下节肥施氮量处理的氮肥损失率降低，氮肥当季利用率和土壤残留率提高；基施氮肥的利用率高于追施氮肥；土壤肥料氮的残留率在 2 9%～ 41 %之间，分布于 1m土层中，其中60 %以上集中在 0～ 2 0cm土层；在整个小麦生长季内，肥料氮并没有淋洗到 1 30m以下。节肥施氮量在常规灌溉下的当季利用率比在节水灌溉下降低 1 6 6%。
