The biomechanical tests showed that two kinds of artificial bones had not significant difference on compressive strength and Young\'s modulus(P＞0.05),while the flexural strength of nano-nacre artificial bone was less than the control group(P＜0.05).3.The results of CCK-8 showed that the difference were not significant in each group,the proliferation of osteoblast reached the peak at the 5th day;7 days after being co-cultured,the total protein content of study group was higher than control group and blank group(P＜0.05),while the difference between control group and blank group was not significantP＞0.05The difference of alkaline phosphatase activities among three groups was not significant(P＞0.05The SEM view showed that osteoblast attached and grew well in two kinds of artificial bone.4.X-ray photography showed that two kinds of powder started to degrade in 2 weeks;this phenomenon became more appear in 4 weeks,nano-nacre powder degraded faster than micron-nacre powder,while the hole shadow was easy to be found;in 8 weeks,all the femoral holes recovered and returned to normal bone mineral density in all groups.Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone grew fastest around the bone defect area in study group,while most slowly in blank groupP＜0.05 SEM(scanning electron microscope observation showed that nano-nacre powder degraded more quickly.The same result can be found through the demineralized sections morphometric analysis,and both of the composite artificial bones made from those two kinds of nacre powder had the good connection with the adjacent tissue in rats body without apparent inflammatory response.5.X-ray photography showed that rabbit\'s bone defects healed faster in study group since NNAB implanted than in control group since MNAB implanted.At 24 weeks after operation,bone density in radial defects had nearly accessed to the normal area,while lower in control group,and turned up nonunion in blank group;The checking of BMD showed that results in study group were higher than those in control group at 8,16 and 24 week(P＜0.05), and the difference between the BMD values in study group at 24 week and those in blank group was not significant(P＞0.05).The gross specimens showed satisfactory histocompatibility both in study group and in control group,with bone tissue growing from two sides into the center of implanted materials; Normal slices in HE stain and hard tissue grinding slices in Stevenel\'s blue/Van Geison\'s picro-fuchsin stain showed that the bone growth tendency was better in study group than that in control group,and the medullary cavity had been penetrated to the implanted materials in study group at 24 week;Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone in both groups grew fastest 8 weeks after surgery,while slow down at 16 week.

纳米珍珠层/消旋聚乳酸复合人工骨与微米珍珠层/消旋聚乳酸复合人工骨分别与成骨细胞共培养后，其各时间点CCK-8法检测值与空白对照无显著差异(P＞0.05)，成骨细胞均在第5天达到增殖高峰期；培养7天后，实验组细胞蛋白含量高于对照组及空白组(P＜0.05)，后两者之间则无显著差异P＞0.05碱性磷酸酶活性在三组间均无显著差异(P＞0.05电镜下可见成骨细胞在两种人工骨上都有良好生长贴附能力。4.X-ray显示两种粉体在大鼠股骨骨洞植入第2周时都开始出现了降解，第4周时更为明显，纳米珍珠层粉较之微米珍珠层粉降解更快，而空白对照组骨洞阴影仍可见，至8周时，则所有组骨洞均己闭合修复，X-ray下已不可见原钻孔痕迹，恢复正常骨质密度；硬组织磨片四环素荧光双标记结果显示纳米珍珠层粉植入组较其余两组在骨缺损区周围新骨生长速度更快，空白组速度最慢P＜0.05电镜观察及常规脱钙切片亦可见到纳米粉体降解较快；由以上两种原材料制得的纳米珍珠层/消旋聚乳酸复合人工骨与微米珍珠层/消旋聚乳酸复合人工骨在大鼠体内均与周围组织结合良好，无明显炎症反应。5.X-ray显示纳米珍珠层/消旋聚乳酸复合人工骨植入兔桡骨缺损区后其骨愈合速度较对照组微米珍珠层/消旋聚乳酸复合人工骨植入的快，至植入术后24周，实验组骨缺损区接近正常骨密度，对照组骨缺损区密度较低，空白组则呈现骨不连状态；骨密度测量结果显示术后8周、16周、24周实验组的骨密度值高于对照组(P＜0.05，24周实验组的骨密度值与术前所测得的正常值无显著性差异P＞0.05动物取材大体所见均显示组织相容性良好，骨组织逐渐由植入材料两端向中央生长；常规切片HE染色及硬组织磨片Stevenel\'s blue/Van Geison\'s picro-fuchsin联合染色均可见实验组骨缺损区长势优于对照组，至术后24周，实验组骨髓腔与材料已呈相交通状；硬组织磨片荧光显微镜下观察，两组材料在术后8周处于骨生长最快速时期，16周时速度开始减慢，术后4、8、16周时实验组的新骨生长速度均较对照组的快

The animal model can be established through transverse osteotomy at bilateral iliopectineal crest,which is an effective method to study the mechanism of compression and bone formation at pelvis and acetabulum.Anatomic fixation and persistent compression corresponding with physiological line of force with ATMFS can promote bone union.

通过双侧髋臼臼顶上方的横形截骨能够建立可靠的骨盆弓状线部骨折动物模型，ATMFS的解剖位固定和其产生的持续顺应生理力线的压应力能够促进骨折愈合。

Whereas the proximal part of the tetrapod limb skeleton can easily be homologized with the paired fin skeletons of sarcopterygian (lobe-finned) fish, there has been much debate about the origin of digits.

早期的假设认为，四足动物的足趾与鱼类的放射鳍同源，但根据发育研究结果，同时根据一种名叫&潘氏鱼&、与陆地脊椎动物密切相关的目前已经灭绝的鱼（这种鱼似乎没有末梢的趾状放射鳍）的鳍，这一观点似乎并不可靠。

You can be waylaid by the unexpected baboon sitting atop a fence post by the side of the road, by the odd shovel-mouthed lizard, or by the huge haystacklike homes of sociable weaver birds.

你会为半路出现的无法预料的动物们而驻足，它们可能是坐在路边篱笆桩顶上的狒狒，古怪的铲状嘴蜥蜴，或者是群居织巢鸟的硕大的像干草堆一样的巢穴。

Originally used in medieval architecture as water spouts or means for diverting watering, gargoyles can be not only grotesques as you see here, but may take the shape of animals and humans–even happy, smiling ones.

怪兽状滴水觜起初是用作中世纪建筑物的喷水觜或者是来形成有趣的水柱的，滴水觜并不仅仅是你在这儿所看到的样子，还有动物和人类形状的，甚至有快乐的微笑的样子。

Species had three kinds of diets during the non-breeding season:(1) mainly invertebrates,(2) mainly fruits, and (3) mainly nectar. This study demonstrated that the diets of 14 passerines during the non-breeding season were significantly correlative with tongue morphology (r=0.424, P .05) and were most correlative with brush length and width of the 3/4 position (r=0.62, P.05). For example, Yuhina brunneiceps's primary diet is nectar and it has the brush-tipped tongue with the longest brush length. Niltava vivida mainly forages for fruits and has a tongue with longer width of the 3/4 position.

十七种鸟类在非生殖季时的食性，亦可分为三大类群：（1）主食无脊椎动物；（2）主食果实；（3）主食花蜜。14种鸟类的舌部形态与其非生殖季食性具有显著相关，其中，仅舌分叉长及3/4位置的舌宽与其食性较有关系，可解释非生殖季食性约36%的解释变异量，也就是分叉长较长的舌头属於刷状卷曲舌形，主食花蜜，以冠羽画眉为代表；3/4位置舌宽较大的舌形，主食果实，以黄腹琉璃为代表。
