查询词典 exoplanet

But all exoplanet detections had been of the squiggly variety.

但是，所有系外行星探测已变得形形色色。

With an estimated temperature of just 50K, OGLE-2005-BLG-390L b is the chilliest exoplanet yet discovered.

根据估算的50K温度，OGLE-2005-390L b是一颗至今发现的寒冷的外部星球。

A Jupiter-mass exoplanet was detected in 2000 by the radial velocity method in which astronomers look for wobbling motion of a star due to the gravitational tug of a planet.

在径向速度法中，天文学家们往往寻找恒星摆动的迹象，这种摆动是由于行星的引力作用造成的。

The gentle pull of an exoplanet as it orbits the host star introduces a tiny wobble in the star's motion — only about 7 km/hour,corresponding to brisk walking speed — that can just be detected on Earth with today's most sophisticated technology.

系外行星在轨道上对宿主恒星的引力是如此&温柔&，对其运动产生的扰动仅有7km/h——相当于我们快步走的速度，今天刚好能被地球上最尖端光谱仪探测到。

Astronomers say they have directly imaged a giant exoplanet orbiting its parent star.

天文学家们称：他们直接拍下了一颗围绕主恒星旋转的巨大行星。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
