Result: The nm-HAP-sol present the dispersed and uniformity needle. A431cells inhibition ratio was maximizing at the 5 day in the 400mg/L nm-HAP-sol group, the 200mg/L nm-HAP-sol group and the 100mg/L nm-HAP-sol group, inhibition ratio of the 400mg/L nm-HAP-sol group, the positive control group and the 50mg/L nm-HAP-sol group was respectively (77.89±6.29)%,(77.46±8.26)% and (1.23±0.15)%. It was detected that the number of A431 cells were persistently increasing in the 50mg/L nm-HAP-sol groups while decreasing in the 400mg/L nm-HAP-sol group, the positive control group and abidingly increasing for 4 and 3 days then decreasing in the 100mg/L and 200mg/L nm-HAP-sol group by inverted microscope.

结果：超声乳化法配制的HAP纳米溶胶呈均匀分散的针状；400mg/L、200mg/L和100mg/L溶胶组对A431细胞抑制率在第5天达到各组最大值，此时400mg/L溶胶组与阳性对照组的抑制率分别为（77.89±6.29）%和（77.46±8.26）%， 50mg/L溶胶组抑制率为（1.23±0.15）%；倒置显微镜下见50mg/L溶胶组细胞数目持续增加，聚集成簇，细胞呈现多角形或梭形，胞浆透亮，而100mg/L 和200mg/L溶胶组的细胞数目分别增加至第4天和第3天开始下降，400mg/L溶胶组和阳性对照组细胞数目持续减少，细胞体积缩小，漂浮细胞增多。

The cells were round before adherence,and anomalism fusiform,triangle and polygon when adhered,monocaryon,1-3 nucleole by invert phase contrast microscopy observation.Alkaline phosphatase staining and mineralized nodules staining were positive(≥98.06%).The osteoblastic activity was the highest on day 10,which was observed by MTT and morphological method.

倒置相差显微镜形态观察结果显示，未贴壁的细胞呈圆形，贴壁生长的细胞呈不规则梭形、三角形或多角形，单核，有1~3个核仁；碱性磷酸酶和钙化结节染色均呈阳性（阳性率≥98.06%）；MTT法结合形态学观察结果显示，成骨细胞培养至第10d时活性最强。

RESULTS: In the physiological saline group, the dendritic cells developed into dendritic arborization with large size in subcircular, polygon or star-shapes.

结果：生理盐水组树突状细胞树突分支增加、增粗、近圆形，体积较大，多角形或具有特征性的星形。

CHAPTER 2 is concerned with the nonlinear hyperbolic equationswhere Ω is a bounded domain with smooth boundaryΩ.

In this paper, the author has introduced a new volume calculation algorithm for polygon model. The general assumption here is that the model is of closed surface .The algorithm described here is based on Mento Carlo method and has a 3D Widgets interaction style.

本文提出了使用蒙特卡罗算法和3d widget交互工具相结合的方式来计算自封闭多角形网格体积的方法，并且分别给出了该方法在Visual Tool Kit和Microsoft Direct3D的实现方案。

After 7 days, some black, circular RPE cells climbed out slowly. Ten days after, cells became irregular, polygon with monolayer-coalesce in bottle bottom, which symbolized as the typical cobble-stone modality after about 13 days.

结果：组织块1d后贴壁，7d后可见有黑色、圆形的RPE细胞缓慢爬出，10d后细胞变成扁平不规则多角形，约13d后细胞基本单层融合长满瓶底，形成典型的鹅卵石样。

RESULTS:①Cytocompatibility of PEG-PLA-PGL membranes with HUVECs: The observation result of phase contrast microscopy showed that, endothelial cells planted on the PEG-PLA-PGL membranes began to attach and stretch after being planted 4-6 hours. Three days later, cells grew in colonies rapidly, after 5 days, colonies began to fuse and seemed like cobble-stone. The cells were shuttle or polygon in shape after passages.

结果：①人脐静脉内皮细胞与聚乙二醇-聚乳酸-聚谷氨酸三嵌段共聚物膜片的细胞相容性：相差显微镜下种植在聚乙二醇-聚乳酸-聚谷氨酸三嵌段共聚物膜片上的细胞4~6 h后即开始贴壁、伸展，3 d后细胞开始呈集落样生长，生长较快，5 d后细胞集落开始融合，呈现特征性的鹅卵石样形态，经多次传代后，细胞呈长梭形或多角形，与对照组相比无明显差异。

Rod material specification regarding to the diametre of round rod.

棒材规格指圆棒直径、如方棒及多角形棒指内切圆直径。

The cortical cells had thin walls and mitochondrium, and nucleus wassurrounded by chloroplasts, and vesicles were next to cell plasmalemma. However, cellwalls of velamen, cortex and exodermis in the mycorrhiza of D. nobile had ring orpapillary thickenings in many cases. The hyphae were surrounded by moremitochondria and vesicles of plant, and the hyphae were digested and their structure waschanged at last. The cell wall of endodermis also had typical ring thickenings, and manysieve orifices in sieve tube elements of phloem were covered by callose, while therewere liaison cords in a few sieve orifices.
