查询词典 Moon

In an annular eclipse, the moon appears smaller than the sun.

日环食发生之时，月亮看上去比太阳要小。

Why Could We Observe Eclipse instead of Annular Eclipse of the Moon?

为什么能观察到日环食，而不能观察到月环食？

The thin ring of sunshine encircling the moon during an annular eclipse is called an annulus.

在日环食期间，绕着月亮的那轮浅浅的太阳光就被称为环面。

An annular eclipse occurs instead of a total eclipse when the Moon is on the far part of its elliptical orbit around the Earth.

而发生日环食而不是日全食的是因为月亮运行到距离地球较远的轨道上，于是月亮的本影只能遮到太阳的中心。

Annularity 环食阶段 The period when the Moon is fully inscribed in the Sun.

为日食中月球影子完全在太阳圆盘里面的阶段。

The next five members of Saros 136 were all annular eclipses; the duration of annularity steadily decreased with each eclipse as the Moon passed progressively closer to Earth.

沙罗136中以下五次都是日环食；当月球日益靠近地球，环食稳定持续时间减少。

As we have seen, this anomalistic cycle coincides with the synodic cycle again after 1 full moon cycl e.

正如我们见到的，这个近点周期和会合周期在每次满月之际都必须符合。

The anorthosite and similar rock types in the highlands and basalt lavas in the marea are the Moon's basic building blocks.

斜长岩和类似的岩石在高地典型，而玄武岩沉积在月球低地构成了月亮基本的建筑积木。

Working from outside the basin in to the Mare Basalts, they find the surface composition changes from Feldspathic breccias (Feldspar is a rock that crystallizes from magma) to shocked Anorthosite (a type of feldspar that makes up the light areas of the moon), to unshocked crystalline anorthosite, to high Calcium pyroxene (a rock made of silicate minerals) and pyroclastic rocks in the center.

研究发现：从盆地外边到盆地内部的玄武岩海（盆地内部的熔岩形成的地质结构），月球表面的地质结构依次是：长石质的角砾岩（长石是火山熔岩结晶形成的岩石）、经过冲击的粒状火成岩（构成月球阳面的一种长石）、没有经过冲击的粒状火成岩结晶体、高钙辉石（一种由硅酸盐构成的岩石），最中心的位置是分裂状的火山岩石。

This conclusion, combined with the data obtained from the short-lived Hf-W and Sm-N d isotopic systematics, suggests that the Moon was initially accreted at 4.5 Ga, followed by development of the global lunar magma ocean. The primary lunar crust is composed by ferroan anorthosite which was produced by flotation of plagioclase during crystallization of the LMO. However, the mafic minerals, coevally crystallized with the plagioclase, sank to the base of the LMO due to their high density, and made up the main part of the lunar mantle, which served as the source during later mare basaltic magmatism.

根据这一年代资料，结合对月岩样品进行的短半衰期Hf-W与Sm-Nd同位素体系的研究结果，认为月球大致形成于45亿年，其后开始由岩浆海导致的内部核－幔－壳的分异，岩浆结晶的低密度斜长岩构成最初的月壳，而密度大的岩石构成月幔，而此月幔则成为后来月海玄武岩的主要岩浆源区。

The receding calculations and experiment analyses in this subject are built on the blood cast of pig tongue.

本研究课题的前期工作是采用猪舌血管铸型模拟人舌而进行的数值计算与实验分析。

"Each human infection constitutes an opportunity for genetic modification of the virus through reassortment, mutation, or both...."

&每一次人类的感染都暗藏着一次基因修改的机会，无论是通过病毒的整合、突变或者兼而有之。。。。&
