The irreparability of the past: once at a performance of Albert Hengler's circus in the Rotunda, Rutland square, Dublin, an intuitive particoloured clown in quest of paternity had penetrated from the ring to a place in the auditorium where Bloom, solitary, was seated and had publicly declared to an exhilarated audience that he was his (the clown's) papa.

317过去的事是已经不可挽回的了。有一回艾伯特。亨格勒马戏团在都柏林市拉特兰广场的圆形建筑里演出，一名富于机智的小丑身穿色彩斑驳的服装，为了寻找乃父，竟走出马戏场，钻进观众席中，来到孤零零地坐着的布卢姆跟前，在大庭广众之下，向兴奋不已的观众公开宣称：他是他的爸爸。

The floral axis pulp, extracts from the bulb, is higher than the leaf slightly, the raceme goes against lives, spends 5~20, each flowered 6 petals, crosswise or the declinator, the funnel shape, the perianth tube long, the base expands,The lobe oval, the counter-volume, likely hemstitching young Zhong, the flower has purple, white, red, yellow, the powder, blue isochromatic, but also has the double petals, the big flower, the early blossoming and polyploid and so on the varieties.

花茎肉质，从鳞茎抽出，略高于叶，总状花序顶生，花5～20朵，每花6瓣，横向或下倾，漏斗形，花被筒长、基部膨大，裂片长圆形、反卷，像个卷边的小钟，花有紫、白、红、黄、粉、蓝等色，还有重瓣、大花、早花和多倍体等品种。

Fund Project: the National Natural Science and Technology Source Program, No. 2001DEA1006*Abstract: Number of neural stem cells is small. NSCs look like circle or ellipse with or without short neurite, with large nuclear-cytoplasmic ratio and deep karyotin. NSCs have no visible differences with other kinds of cells in appearance, and have no cell surface marker. Currently, there are mainly three aspects to identify NSCs: expression of specific nerve antigen, including nestin, Musashi, transcription factor, and cell adhesion molecules; self-renewal ability including single cell clone analysis, BrdU mark and S phase cell; the potential of multi-direction differentiation including immunocytochemical process and reverse transcriptase polymerase chain reaction.

由于神经干细胞的数量很少，从细胞形态来看神经干细胞为圆形或椭圆形，无或有较短的突起，核质比大，核染色较深，形态上与其它种类的细胞没有明显的差异，并且未找到一种细胞表面特异性标志物，因此目前鉴定神经干细胞主要有以下3个方面：特异性神经抗原的表达，包括巢蛋白、Musashi、转录因子及细胞黏附分子；自我更新能力，包括单细胞克隆分析、BrdU标记S期细胞；多向分化潜能，包括免疫细胞化学法、聚合酶链反应色法。

In Kensington Gardens you can see the statue of Peter Pan, or visit the Round Pond, where people put little boats in the water,,and play with them.

在肯辛顿花园，你可以欣赏到彼得·潘的雕像，还可以游览圆形池塘，在那里人们将小船放入水中嬉戏。

Shape: Rotundity and squareness, Can middle keypunch and come picture make to measure.

形状：圆形和方形，可中间打孔及来图定做。

According to shape into round, kidney-shaped, rectangular, circular, elliptical, etc..

Has entered the flowering period of strong ginkgo tree, spur on the shape of the three can be seen traces of traces of the bud scales linear scar, kidney-shaped scar that leaves marks, circular scar is spent stalk marks.

已经进入开花结实期的银杏树，短枝上可以见到三种形状的痕迹；线形痕是芽鳞痕，肾形痕是叶痕，圆形痕是呆柄痕。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
