The relation between the spectrographic aperture ratio and elliptical eccentricity, spectral angle is also analyzed according to the elliptical geometry, it will decrease when the x-ray wavelength increases.

根据椭圆的几何关系，研究了光谱相对孔径与椭圆的离心率和谱线探测角之间的关系，它随X射线波长增大而减小。

Once the price of medium-term deviation from the average rate of re-amplification, Italy.

一旦价格对中期均线的乖离率重新放大，则意。

The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

利用基尔霍夫衍射理论计算了四圆孔径衍射屏在菲涅尔深区形成的的干涉光场的强度、零值线和相位的分布，发现干涉光场亮斑关于中心呈对称分布，在距离衍射屏较近的观察面上，光强值为的零点组成光强零值线段，该线段上光强等值线的离心率都接近或等于1，其两侧的光强值变化非常剧烈。

And then the point spread function can be acquired through Abel reverse transform, according to the circular symmetry characteristic of the defocused image.

由于离焦造成的图像模糊是圆对称的，对线扩散函数进行阿贝尔逆变换就得到了点扩散函数。

The third line is called the intertubercular, and runs across between the two rough tubercles, which can be felt on the outer lip of the crest of the ilium about two and a half inches (60 mm) from the anterior superior spine.

第三条线为结节间线，在两粗大的结节间走过，位于髂骨嵴的外唇，离髂前上棘大约2.5寸（60 mm）处。

本研究通过对80例离体上颌第一磨牙行近远中方向，颊舌方向x 线投照，旨在近一步了结其根管的弯曲走向，弯曲程度，弯曲位置。X线片只能反应根管在一个平面上的走向、形态。

The kite has unrolled so you are ready to pull with both lines and fly away.

风筝解开绕线了，你要准备好拉双线并飞离。

A wire tying tool having a set of movable talons (400, 401) for channeling a loop of hard wire fed from a spool (600) around an object to be tied with a wire knot at high speed; a wire drive (364) with a pullback feature to retract the loop under tension to tighten the loop around the object; a clutch-controlled retractable reel to hold the tension on the wire on the reel; a spinner/cutter that extrudes a knot by turning, kinking and cutting the wire, and then rotating to twist the wire into a knot while drawing the spinner away from the work surface.

一金属丝捆扎工具有一组带有引导从一卷线筒（600）高速传送来的围绕将被一金属丝结捆扎的物体的、硬金属丝环的通道的可运动的爪钳（400，401）；一具有回拉功能的以便在拉力状态下回拉此环以拉紧围绕物体的环的金属丝传动（364）；一离合器―控制的可回拉的、保持金属丝张力的卷线轴；当旋转器被拉离工作表面时通过转动、扭结和切割金属丝以及然后旋转、以便扭转金属丝形成一结而挤出一结的一旋转器／切割器。

The train is then stopped and the overhead leads removed. The leading car is then used to drag the rest of the train out of the shed. Care has to be taken to ensure all leads are removed before allowing a train to leave the shed and enter service.

然后列车要停下来，将悬吊线解下，由第一节车牵引列车出库，在列车离库进入运用前，必须确认所有的悬吊线都从车上解下。

The continental divide refers to an imaginary line in the North American Rockies that divides the waters flowing into the Atlantic Ocean from those flowing into the Pacific.

大陆分水岭是指北美洛矶山脉上的一道想象线，该线把大西洋流域和太平洋流域区离开来。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
