We observed that EPCs can regenerate damaged endothelial cells in vascular grafts in apoE-deficient mice, and that abundant vascular progenitor cells are present in the adventitia of the vessel wall.

我们的研究发现，内皮祖细胞可修复apoE缺陷小鼠血管移植物中的损伤内皮并且在动脉血管外膜中存在大量的血管祖细胞。

The underground root systems and the plenty of adventive roots growing on basis trucks can greatly reduce soil erosion by reservoir water. The 1 m×1.5 m allocation density of the Salix viminalis showed the best protection, and sediment yield was 8.64 kg/m^2, which decreased 74.38% compared to CK.

柳树根系及主干基部长出的大量不定根，可减缓水库水流对滩地土层的冲蚀，以青刚柳1m×1.5m密度配置的防护效果最好，冲蚀量仅8.64kg/平方公尺，比对照减少74.38%。

The plant expression vectors were constructed and two genes were transferred into A. thaliana and N. tabacum, antikanamycin plants were obtained.4. The trials of adventive bud regeneration directly and callus induction was conducted to select out the optimal explants and formula. The results revealed that double scale can produce 13~16 adventive buds per centimeter in MS medium added 10.0 mg/L 6-BA, 1.0 mg/ L NAA, 40 g/L sugar and 7.5 g/L agar. Scale, leaves, scape and different tissue of flower can be induced to produce callus in appropriate medium, but the filament with anther was the optimized explant.

构建了两个基因的pBI121和pCAMBIA1300植物表达载体，并通过农杆菌将上述基因转入烟草和拟南芥中，得到了卡那抗性的再生植株。4、以中国水仙不同部位外植体进行了不定芽直接分化和愈伤组织诱导分化试验，结果表明，双鳞片外植体在MS0+6-BA 10.0 mg/L+NAA 1.0 mg/L+蔗糖40 g/L+琼脂7.5 g/L培养基上可以大量地直接再生，再生芽数量平均可达13~16个/cm双鳞片，比传统的鳞茎盘之间分化提高30~50%；鳞片、叶片、花葶及花部不同组织在适宜的配方中均可不同程度地诱导出愈伤组织，但以带花药的花丝诱导出的愈伤组织最好。

Because of the influx of monsters and Visitors, the Adventurer's

由于大量的怪物和游客，冒险家的

In the term of price ,it absolutely belongs to the the first three in the world .it gives a lot of care and money on its material and exterior .its high price is mainly due to its abundant diamonds ,and advertizement .which is not very professional on its core ,usually using other company 's .

伯爵。若单以价格而言，伯爵绝对是前3名的，不过，本人之所以不太看得上它，是因为它的高价格主要是靠运用了大量的钻石和宝石镶嵌，以及市场运作所造成的。伯爵自己不擅长做机芯，通常用别家的机芯，但是在外壳设计和用料上却特别下功夫、舍本钱。

It also presents some advices on how to improve the performance of neural network.

通过大量的股市预测实验，本文研究了各种参数对于预测结果的影响，并提出了改进的方向。

And Yangshao - Majiayao, Changshan different classes, such as culture, the culture of a large number of selected Qijia higher hardness of jade is expected to produce tools, shovel jade, jade adze, Yue Yu, Yu-cutting and other small delicate, regular-type, species polished, sharp edge.

与仰韶-马家窑、常山下层等文化所不同的是，齐家文化大量选用硬度较高的玉料来制作工具，玉铲、玉锛、玉钺、玉凿等小巧精致，器型规整，通体磨光，刃口锋利。

Regarding anisotropic material (including orthogonal aeolotropy) crack expansion question analysis and research, the people although have done the massive research work, but accumulates data is actually limited.

对于各向异性介质中裂纹扩展问题的分析和研究，人们虽已做过大量的研究工作，但所积累的资料却十分有限。

With economic development, the rock material is widely applied in the water conservation、 resources mining、 the civil construction 、 the railway and so on, a lot of problem about rocks urgently is demanded to solve, so there are very important theory and realistic meanings to thoroughly research its nature、 concerning and destroying mechanism,Due to natural function, massive joint and crack with rock, though the scale of these is small, it changes mechanics nature of rock greatly and reduces deforms mould and intensity parameter, and makes it presenting aeolotropy .

随着我国经济建设的发展，岩石材料被广泛应用于水利、资源开采、土木建筑、铁路等领域，与此同时出现许多岩石方面迫切需要解决的问题，所以对其性质、本构关系、破坏机理的深入研究有重要的理论意义和现实意义。由于天然作用，岩石内部存在大量的节理和裂隙，虽然这些裂隙的规模不大，但裂隙的存在大大地改变了岩体的力学性质，使其变形模量及强度参数降低，且使岩体的力学性质呈各向异性。

The crystals exist in parenchyma cells of its petioles. Its petioles have big vessels and much aerenchyma.

叶柄薄壁细胞存在晶体，叶柄的导管管径比较大，有大量的通气组织。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
