In another moment she felt the train go straight up into the air.

过了一会儿，她感觉火车空中开去。

Previously when the Shenzhou-14 manned spacecraft docked radially with the space station, it weighed only 47 tons.

以前，当神舟14号载人飞船与空间站进行对接时，它的重量只有47吨。

Except Ctenoimbricata didn't have radial symmetry.

除了 Ctenoimbricata 没有对称性。

And just like other forces, vector addition also applies here, too.

它们吸引，并且像其他力量一样， 我们将求和应用于我们的案例。

So how did the ancient ancestors of starfish go from having bilateral symmetry to having radial symmetry?

那么海星的远古祖先是如何从左右对称变对称的呢？

But why five-part radial symmetry, specifically?

但具体为什么是五部分对称呢？

Those who use public transport often need radial routes whereas most systems favour commuters heading from the suburb to the centre of town.

那乘坐公共交通的人通常需要路线，而大部分交通体系偏于让通勤者从市中心。

The evolutionary past of starfishes from bilateral to radial animals is also echoed in their development.

海星从双侧动物动物的进化历史也反映在它们的发展过程中。

Sea cucumbers are members of the phylum Echinodermata, along with sea urchins, starfish and other radially symmetrical, " spiny-skinned" marine invertebrates.

海参是棘皮动物门的员，还有海胆、海星和其他对称的“多刺”海洋无脊椎动物。

The first radially symmetrical echinoderm known from the fossil record is Camptostroma, which showed up between 516 and 513 million years ago in Pennsylvania.

化石记录中已知的第一个对称棘皮动物是 Camptostroma，它出现在 516 5.13 亿年前的宾夕法尼亚州。

At 4: 29 pm on Tuesday, some six and a half hours after launch, the Shenzhou-16 spacecraft docked with the Tianhe core module's radial port, announced the CMSA.

中国航天局宣布，周二下午4点29分，发射约6个半小时后，神舟16号飞船与天河核心舱的端口对接。

Unlike the Grand Canyon, it wasn't carved by water; it may have formed when the Tharsis bulge rose up, creating the valley as a radial crack in the surface.

与大峡谷不同，它不是由水流蚀刻而的；水手谷可能是在塔尔西斯隆起升起时，在火星表面形的裂痕。

Our adieux were limited to a hasty bow, and then I pushed forward, trusting to my own resources; for the porter's lodge is untenanted as yet.

我们的告别仅限于匆忙一鞠躬，然后我就前去。相信我自己有本事，因为守门人的住处还没赁出去。

If you're just going to sit still, capture food, and not move around, the radial body plan may help you better access food in 360 degrees.

如果您只想坐着不动， 捕捉食物，而不是四处走动，身体计划可能会帮助您更好地 360 度获取食物。

This is the first manned space mission in the space station's application and development phase, and the first radial rendezvous and docking performed under the T-structure formed by the three modules.

这是空间站应用和发展阶段的第一次载人航天任务，也是三个模块组的T型结构下进行的第一次交会对接。

They have radial symmetry - with a mouth at their center and their other body structures repeating around it in sets of five, like the spokes on a wheel.

它们具有对称性——在它们的中心有一张嘴， 它们的其他身体结构以五个一组的形式围绕它重复，就像车轮上的辐条一样。

Radial gates control how much water is released and massive  concrete blocks at the bottom of the chute, called dentates, disperse the flow to reduce erosion as  it crashes into the Feather River.

闸门控制释放的水量，滑槽底部的巨大混凝土块（称为齿状）可以分散水流，以减少水流流入羽毛河时的侵蚀。

The facility consists of an earthen embankment which forms  the dam itself, a hydropower generation plant that can be reversed to create pumped storage, a service spillway with 8 radial floodgates, and an emergency overflow spillway.

该设施包括形大坝本身的土堤、可反转以形抽水蓄能的水力发电厂、带有 8 个闸门的服务溢洪道以及紧急溢流溢洪道。
