查询词典 median line

An influential exponent of the first approach was Lester Thurow of the MIT's Sloan School of Management, who took as his reference point the median income in America—where there is an equal number of people above and below the line—and defined the American middle class as the group with incomes lying between 75% and 125% of the median.

第一种方法有影响的倡导者是麻省理工斯隆学院的莱斯特·梭罗，将美国收入的中间值作为他的参照点——在这个线的上方和下面有相同的人数，然后他定义收入在平均收入75%到125%的范围内的群体为美国的中产阶级。

The median voter theorem is a mathematical result that shows that if voters are choosing a point along a line and each voter wants the point closest to his most preferred point, then majority rule will pick the most preferred point of the median voter.

中值选民定理是一个数学结论，这个结论表明如果要选民沿着一条线选择一个点，而且每个选民都想选离他最偏好的点最近的点，那么多数规则将选出中值选民最偏好的点

The peak of the bulge accorded with the vertical line through the posterior convexity of superior articular surface of atlas. The superimpose rate of the vertical line with the M line were 48% to left and 65% to right. The surplus existed in l～2mm to lateral of M line. The exit point of screw was the median point of vertical line on the anterior cortex of lateral mass. The superimpose rate of BB line the line linked with the

寰椎后结节中点及上关节突后凸尖下的骨质弧形隆起的顶点可作为寰椎椎弓根螺钉进钉点的准确标志，上关节突后凸尖及横突尖可作为寰椎椎弓根进钉点的大体标志；沿寰椎椎弓根轴线进钉较为安全，内倾17°，仰角变异大，出钉参照前结节顶点；椎动脉沟中外的厚度及进钉点处寰椎后弓的高度是寰椎椎弓根螺钉固定的主要限制性因素。

When the digitalsignal carries on the long distance transmission, the high frequencycomponent weaken increases along with the distance increases, theelectric cable median line also advances to the betweenelectromagnetic radiation along with the frequency intensifies, thusthe clipped wave transmitting range and the transmission quality,simultaneously in the channel often also exists separates the directcurrent electric capacity and the coupling transformer, they cannottransmit the direct component and have a bigger weaken to the lowfrequency component, therefore high frequency and low frequency arepartial regarding the common channel is limited.

当数字信号进行长距离传输时，高频分量的衰减随距离的增大而增大，电缆中线对之间的电磁辐射也随着频率的增高而加剧，从而限制信号的传输距离和传输质量，同时信道中往往还存在隔直流电容和耦合变压器，他们不能传输直流分量及对低频分量有较大的衰减，因此对于一般信道高频和低频部分均是受限的。

The lingual nerve and its neigh-bouring structures were investigatedon 33 sides of head-neck specimensand 61 mandibulae.At median line ofthe third molar,the distance betweenthe lingual nerve and the gingive me-asures 11.7mm.

在33侧成人头颈部标本和61块下颌骨标本上对舌神经在下颌第三磨牙舌侧区的位置及其与周围结构的毗邻关系进行了观测。

The improved model possesses band-pass filer characteristic, diffuses processing stability and satisfies the max-min principle. The simulation results show that the median filter is only proper for outlies noise and removes the thin line and corners of image. The linear filter extends or blurs the boundary of image. The anisotropic diffusion removes random noise effectively, but it brings about illusive edge and back diffusion for outlies noise. The improved model that possesses both median filter characteristics and anisotropic diffusion capability is proper for various mixed noise and can sufficiently protect the detailed characteristic such as corner, thin line and edge.

研究结果表明：中值滤波作为一种经典的非线性滤波方法仅适合于&飞点&噪声的滤波并引起图像的角点、线条损失，线性滤波扩大或使图像边界范围模糊；传统的各向异性扩散能对随机噪声有效地压制，但对&飞点&噪声会产生虚假的边缘甚至反扩散，而改进模型既具有中值滤波的特性又具有传统各向异性扩散的性能，适合于平滑不同强度与形状的混合噪声，并对角点、线条、边缘等细节信息提供足够保护。

The right parietal bone of anesthetized rats was exposed, and bone window of 5 mm was opened 2 mm near median line, then moderate brain injury was made by sap pressure, and the rat models of tibial fracture were established. The fracture group was only subjected to cranial bone window, and the control group was not given any treatment.

实验方法：麻醉后显露大鼠右颅顶骨，中线旁2 mm 处开直径5 mm 骨窗，液压打击致中度脑损伤，并制备大鼠胫骨骨折模型，其中单纯骨折组头部只做颅骨开窗，正常对照组不做任何处理。

Unlike the Pointer, the median line between the eyes at the forehead is not too deep and the occipital bone is not very conspicuous.

最重要的特点是骨骼的尺寸不能太夸张，而是希望骨骼与身躯能形成正确的比例。

Unlike the Pointer, the median line between the eyes at the forehead is not too deep and the occipital bone is not very conspicuous.

不像指示猎犬，前额两眼间中线不太深，枕骨部不太明显。

The skull mayshow some median line; the occipital bone is not conspicuous in maturedogs.

头部略微显示出一点中心线；成熟狗的后枕骨不显著。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
