查询词典 at a distance

Imaging-based measurements of introversion angle, declination angle, entry point and distance of spinous process at the horizontal plane are important data for percutaneous vertebroplasty. According to pedicle shape features at different stages, included angle, puncture point, path and depth, the vertebroplasty could be performed accurately and safely with reduced damage. Moreover, reliable data are provided for the design of a three-dimensional puncture-oriented device.

He also figured out the planet goes faster when it's at perihelion, nearer the sun, than when it's at aphelion, its furthest distance. Which would explain why summer seems to zip by, except the seasons are a function of the tilt of the earth's axis, not its different distances from the sun.

他还计算出地球在近日点时运行速度，比在远日点更快，这就可以解释为什么夏天好像比较短，另外，季节与地球轴的倾斜相关，不是因为地球与太阳距离远近的不同而造成的。

He also figured out the planet goes faster when it's at perihelion, nearer the sun, than when it's at aphelion, its farthest distance-which would explain why summer seems to zip by , except the seasons are a function of the tilt of the Earth's axis, not its different distances from the sun.

他还计算出地球在近日点时运行速度，比在远日点更快，这就可以解释为什么夏天好像比较短，另外，季节与地球轴的倾斜相关，不是因为地球与太阳距离远近的不同而造成的。

At and , we can get a univariate cubic equation in and its three roots . By the dependence of the roots and the coefficients of the equation, we can choose corresponding space points ( such that the distance is the shortest from to the point with parameters and . Thereby we can get all the data of discrete points on the cubic curve of blending surface at . Again we denote the maximum value and minimum value of planar parameter with which meets by and respectively.

利用根与系数的连续相依性，可以选相应的空间点使其距离的圆截线上对应值的点最近的两个根，从而得到处拼接曲面的截线的离散点的数据并确定出与相截的平面参数的最大最小值类似地由处拼接曲面截线的离散数据得到处的离散数据，这样可以依次计算出拼接曲面上对应所有参数点的离散点的坐标。

The results that the ultrasonic intensity have a direct ratio to the currents at electrode, when using this methods in the reduction of 〓 at Pt microelectrode, shown the manner of ultrasonic effect on the mass transfer on the electrode surface. And the inverse ratio relationship of current amplitudes to the separation of horn-electrode shown the decay law of ultrasonic intensity with distance.

将这一方法应用于铂电极上铁氰化钾还原反应体系中的研究结果表明，超声功率与电极反应电流幅值信号呈正比的关系，反映了超声能量对电极表面传质过程的影响程度的对应关系；电流信号幅值与超声作用距离的反比例关系则反映了超声振动能量随其辐射距离增大而衰减的规律性。

At first, using the gravitation mode the article confirms the range of Xi'an district, then the article carries on the analysis of the distance optimizing, economic linking, perimeter urban industry basic and water resources protection, then propose " a pair of axis "and" a pair of level " mode, and establish the xi'an satellite city, they are Xianyang, Lintong, Changan, Yanliang, Gaoling, Huxian, Xingping , Liquan , Jingyang , Sanyuan , Qianxian. Then on the basis of analyzing the industry shift of Xi'an, he article confirm the function of every satellite city; At the same time point out the study and adjust of Xi'an satellite city should be strengthened, and strengthen the industrialization construction of the infrastructure, then propose to build one pair of rings structure of traffic facilities.

文章首先应用引力模式确定西安都市区范围，继尔经过优化距离分析、经济联系紧密度分析、周边城镇产业基础分析及水资源保护限制分析后，提出了&双轴线、双层次&发展布局模式，确立了西安包括咸阳、临潼、高陵、户县、兴平、礼泉、泾阳、三原、乾县、阎良、长安十一个卫星城；继而在分析西安市产业梯次转移的基础上，确定了各卫星城的职能；同时指出要加强西安卫星城基础设施发展的研究及调控，要加强基础设施产业化建设，提出建设交通设施的双环结构。

At 400 kilovolts, a standard value for long-distance transmission, an alternating current 30 metres (100 feet) from the ground has a fortieth of the loss of a similar cable at ground level.

在远距离传输的标准电压400千伏下，电缆离地30米（100英尺）时的电量损耗是同样电缆在地面时损耗的四十分之一。

At 400 kilovolts, a standard value for long-distance transmission, an alternating current 30 metres (100 feet) from the ground has a fortieth of the loss of a similar cable at ground level.
