子午线

The antipodal meridian of Greenwich is both 180 W and 180 E.

与本初子午线相对的经线既是180 W 也是 180 E。

The virtual assemblage of a rim （22.5×9.00） and a tubeless radial tire （12R22.5） were created by Autodesk Inventor, and the insertion model was designed based on the virtual assemblage of the rim and tire through inplace designing, the interference checkout, the presentation views, and the engineering drawings were associatively created and the consistent data were ensured among them during designanalysisredesign cycles.

利用该软件创建22.5×9.00轮辋和12R22.5无内胎子午线轮胎虚拟装配体，基于装配体在位设计内支撑模型，并进行干涉检查、创建表达视图和工程图。

A coordinate was established with the horizontal, vertical and optical axis defined as the X, Y and Z axis. A circumrotation was then made.

通过建立三维座标系、座标轴旋转、解方程组，求得各个子午线上的二次曲线表达式及Q值。

The ocular accommodation has a great influence on refractive components. It is not only the process by which the refractive power of the lens is increased. But the lens itself moved forward relatively. The accumulation effects of accommodation induced by near-work is the main cause of myopia developed in children. The asymmetry of corneal surface was not only related to keratometer K1 and K2 , even the curvature within the same horizontal or vertical meridian was asymmetry.

调节本身不仅是传统意义上的睫状肌收缩和晶状体变凸，同时还伴有晶状体的相对前移；调节对眼的几乎所有屈光构成因素有着显著的影响，视近活动的累积效应是儿童近视眼发生的主要原因；角膜的非球面性不但表现为两个相互垂直子午线的曲率不等，即便是在同一垂直或水平径线上的屈光分布也是非对称的。

Tte also suggest a possible comparison with the Ediacara trilobozoan fossils-Albumares and Anfesta from the shores of the White Sea in Russia. The re-cent discovery of a few skewed E. octobrachiata and walnut-shaped fossils with several carbonaceous meridian bands believed to represent lateral compressions of the same organism strongly suggests that this octoradial fossil is a ctenophoran.

新发现的倾斜保存的八臂仙母虫化石和碳质条带呈子午线状排列的核桃状化石，可能是该类化石归属栉水母类的有力证据，这一发现推测可将栉水母类的最早化石记录从&澄江生物群&的早寒武世推前大约3千万年。

As one ascends, one begins to reweave the energy flow of the grid work and meridians to increasing levels of light within.

当你提升，你开始重织晶格层和子午线的能量流程，增加内在光明的幅度。

Finite element analysis model of 9.00 R 20 radial tire was built and the static stress－strain distribution in the contact area was analyzed.The material and geometric nonlinear properties,and the anisotropic property of composite materials as well as uncompressible property of vulcanized rubber were studied.The effects of quantity of deflection, inflated pressure and friction coefficient on stress distribution in the contacting area were analyzed.

建立了9.00R20子午线轮胎的有限元分析模型，从轮胎的材料非线性、几何非线性、橡胶帘线复合材料的各向异性，以及橡胶材料的不可压缩性等方面探讨了轮胎与地面的静态接触问题，分析了下沉量、充气压力及静摩擦系数等对轮胎静态接地面内应力应变场的影响。

The time for one complete rotation of the earth relative to a particular star, about 4 minutes shorter than a mean solar day.

春分点相继两次越过一个地方的上子午线的时间间隔，即等于平太阳时小时分/秒。

One product that disinfects water with UV light is called AquaStar made by Meridian Design.

有一种产品叫做AquaStar，就是用UV光线来消毒的，是由子午线设计公司制造的。

One product that disinfects water with UV light is called AquaStar, made by Meridian Design.

有一种用紫外线对水进行消毒的产品叫做Aquastar，由子午线设计公司制作。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
