When I meet the engine with its train of cars moving off with planetary motion —— or, rather, like a comet, for the beholder knows not if with that velocity and with that direction it will ever revisit this system, since its orbit does not look like a returning curve —— with its steam cloud like a banner streaming behind in golden and silver wreaths, like many a downy cloud which I have seen, high in the heavens, unfolding its masses to the light —— as if this traveling demigod, this cloud-compeller, would ere long take the sunset sky for the livery of his train; when I hear the iron horse make the hills echo with his snort like thunder, shaking the earth with his feet, and breathing fire and smoke from his nostrils(what kind of winged horse or fiery dragon they will put into the new Mythology I don't know), it seems as if the earth had got a race now worthy to inhabit it.
当我遇见那火车头,带了它的一列车厢,像行星运转似的移动前进,——或者说,像一颗扫帚星,因为既然那轨道不像一个会转回来的曲线,看到它的人也就不知道在这样的速度下,向这个方向驰去的火车,会不会再回到这轨道上来,——水蒸汽像一面旗帜,形成金银色的烟圈飘浮在后面,好像我看到过的高高在天空中的一团团绒毛般的白云,一大块一大块地展开,并放下豪光来,——好像这位旅行着的怪神,吐出了云霞,快要把夕阳映照着的天空作它的列车的号衣;那时我听到铁马吼声如雷,使山谷都响起回声,它的脚步踩得土地震动,它的鼻孔喷着火和黑烟(我不知道在新的神话中,人们会收进怎样的飞马或火龙),看来好像大地终于有了一个配得上住在地球上的新的种族了。

The residual stress in bent pile can be ignored. The curvature of batter pile has important influence on additional moment to bent pile under vertical load on top. When the radius of curvature on the upper segment of pile is small, the additional moment can not be ignored.
得到以下结论:桩体由于施打而发生的弯曲在桩体中产生的残余应力可以忽略不计;桩顶竖向荷载作用下桩身的弯矩同桩的偏斜曲线有重要关系,桩顶处的曲率较大时,桩身的弯矩在工程中是不能忽视的。

The morphology and structure of reconstructed tissue was detected by microscope and scanning electron microscope.Results:(1) Compared with the control group, the cellular proportion of laminin group increased in 62 ~M phase, and decreased in Go~Gi phase significantly. As shown by the microscope, the cells of control group were in low density. The cells in mass connected tightly. The microfilament appeared reticular formation. The nucleus were the same in size. The cells of laminin group were in high density and put out so many lamellipodia, filopodia, which connected with the surrounding cells. The microfilament increased, elongated, and changed from reticulodromous to sarciniform, which reached to the pseudopods. The nucleus were different in size .(2) As shown by the inverted microscope and the cell growth curve, comparing with the controlgroup, cells of each test group increased evidently. The cellular proportion of each test group increased in S phase and G2 ~M phase, and decreased in Go~Gi phase significantly, but there was no considerable interations between LN and EGF;(3) As shown by the morphological observations, the cultured cat corneal endothelial cells formed an integrated membrane, and attached to the Descemets membrane closely, which was similar to the natural tissue. The cells connected tightly to each other, and some of them arranged in hexagon approximately.
结果:(1)层粘连蛋白组处于G_2~M期细胞比例较对照组显著提高,Go~G_1期细胞比例显著下降,提示层粘连蛋白促进内皮细胞DNA合成,及细胞分裂增殖;光镜下,对照组细胞分布成团状,细胞密度较低,细胞间连接紧密,细胞内微丝结成网状,细胞核大小一致;与对照组相比,层粘连蛋白组细胞生长旺盛,细胞密度高,向周边伸出大量板状及丝状伪足,细胞内微丝增多、拉长、集结成束,伸入伪足中,细胞核形状大小不一致;(2)倒置显微镜观察及细胞生长曲线显示,各组细胞数目随时间增加而明显增多,各实验组较对照组增生显著,EGF和LN联合应用组各时间点细胞数目最高;实验组处于S期和G_2~M期细胞数目增加,Go~G_1期细胞数目减少;提示EGF、LN单独及联合应用均可促进细胞增殖,但尚不能认为二者有交互作用;(3)倒置显微镜下,组织培养的猫角膜内皮细胞排列成密集的单层,细胞间连接紧密;组织学观察发现,培养的猫角膜内皮细胞形成完整的内皮层,贴附于脱水基质的后弹力膜上,与正常的角膜内皮组织结构相似;扫描电镜下,组织培养的猫角膜内皮细胞间紧密镶嵌排列,可见某些细胞呈近似六边形排列,细胞大小不甚一致,胞核清晰。
