His letters to Kepler, discoverer of the laws of planetary motion, explain the application of his "calculating clock" to the computation of astronomical tables.

The list starts with Archimedes and Kepler, whose three laws of planetary motion were not, incidentally, called "laws" by either him or Newton.

In putting together this materialist view of the world, Hobbes was influenced by his contemporaries Galileo and Kepler, who had discovered laws governing planetary motion, thereby discrediting much of the Aristotelian worldview.

In many ways, Galileo was a more modern thinker than Kepler (Galileo's contemporary) or Newton (whose single greatest accomplishment, apart from the invention of calculus, was the explanation of Kepler's three laws of planetary motion and their implications for the law of universal gravitation).

在许多方面，比起刻卜勒或牛顿（除了发明微积分外，牛顿的最大成就在於解释刻卜勒行星三大运动定律，以及它们在万有引力定律上的蕴意），伽利略是更现代的思想家。

IYA2009 also celebrates the work of Johannes Kepler, a German astronomer who published Astronomia Nova in 1609. The groundbreaking work was the result of a decade of research on the movement of planets in our solar system. Kepler's models ─ known as Kepler's Laws of Planetary Motion ─ are still used by astronomers today.

此外，国际天文年也同时庆祝克卜勒的成就，这位德国天文学家在一六0九年出版《新天文学》一书，这本划时代的开创性巨作是克卜勒耗费十年研究太阳系星球运行的心血结晶，被称为克卜勒定律的「克卜勒行星运转定律」，至今仍然备受天文学家遵循。

To understand the increasing sizes of the circles according as the celestial body moves farther away from the sun, one has to be aware of Kepler's second law of planetary motion.

为了解各界日益增加的大小根据作为移动的天体远离太阳，人们必须意识到开普勒的行星运动第二定律。

Each planet speeds up when it is nearer the Sun and travels more slowly when it is far from the Sun (this is Kepler's Second Law of Planetary Motion).

各个行星加速当它太阳是更近的并且慢慢地旅行当它在离太阳很远的地方(这是星球运动Kepler's 第二法律)。

According to Kepler's second law of planetary motion the celestial body then should stay 2 squared or 4 times longer in the sign of the zodiac when the planet is most remote to the sun compared to the situation the planet is most nearby to the sun.

根据开普勒的行星运动的天体，然后应留2平方或4倍的星座时，地球最遥远的太阳已签署第二定律的情况相比，这个星球最邻近的太阳。

It took Kepler over thirty years to produce the three laws of planetary motion.

它开普勒三十多年生产三部法律的行星运动。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
