爬行

Two days after bone marrow MSCs compounded to nano-CS/COL scaffold, bone marrow MSCs presented globular shape and were scattered; Four days later, bone marrow MSCs presented shuttle shape, extended and anchored on the surface of nano-CS/COL by pseudopods; Eight days later, bone marrow MSCs proliferated and fused each other, and they secreted a lot of extracellular matrix, then which covered most material particles.

骨髓基质干细胞复合到纳米壳聚糖-胶原纤维支架后2 d，细胞呈球形散在分布；4 d 后细胞呈梭形，延展爬行且有伪足与材料表面锚靠；8 d 时细胞增殖，相互间融合，并有大量的细胞外基质分泌，大部分材料颗粒被覆盖。

They are crawling on precipices that are by the sea.

这些生物，爬行在峭壁之上，而峭壁又君临大海。

This paper develops Prof. Ichi1aw's creep theory. A series of creep ealculation formulas of the hydraulic motor are devrived. Taking Staffa motor for example, this paper conducts theoretical calculation and some experiments and computer simulation. The results are in such correspondence that it is possible to pre-estimate and determine the minimum steady rotatory speed.

本文对日本市川常雄教授关于&爬行&的研究进行了拓展，推导出了一系列液压马达低速指标计算公式，并以Staffa型液压马达为具体研究对象，进行了理论计算、台架试验测定和计算机仿真，其结果有较好的一致，从而实现了对液压马达最低稳定转速进行预估和标定。

I could see the many palps of its complicated mouth flickering and feeling as it moved.

我可以看到它爬行时，结构复杂的嘴里伸出许多触须在摇曳探索。

Dinosaurs did not achieve their great size or domination overnight - they evolved alongside reptiles and mammals, but managed to outcompete them.

他们像爬行，哺乳动物一样进化着，不过他们也想战胜其他物种。

It was the first of several orbiters that are surveying the cold, barren landscape, looking especially for signs of water and relaying signals from the two robotic rovers crawling over the terrain.

这对多个卫星来说都是第一次在这个寒冷贫脊的土地上勘探水的痕迹。这两个机器人式的漫游者在火星上爬行并将信号发射出去。

Newts, crawling things in slime and mud, poisons

蝾螈，在污泥浊水中爬行的东西，毒药

For example fish, newts and reptiles have been moved to local sites during the construction phase of the project and artificial nests were created for sand martins along the Lower Lea Valley.

比如，在进行工程施工时，鱼类、蝾螈和爬行类动物已经被转移到其他地方，并沿着下利河谷区搭了很多人造鸟巢，供堤燕居住。

Those microorganisms are the major cause of the wood rot for your crawl space .

主要原因是这些微生物的木材腐烂您爬行空间。

The lark's on the wing, the snail's on the horn .

云雀在空中飞翔，蜗牛伸出触角爬行。

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。
