矮行星

It is just weeks since Pluto was redefined as a dwarf planet .

冥王星被重新定义为矮行星只是几个星期前的事。

To understand this, we must look at the cosmology of the day of the formation and then we find out that the sun on this day is in conjunction with the dwarf planet Sedna!

要理解这一点，我们必须看看在当天的形成宇宙，然后我们发现，在这一天的太阳与矮行星塞德娜一起啊！

Now Pluto will be called a dwarf planet along with at least two others.

现在冥王星和至少其他两个将被称为矮行星。

According to IAU, a "dwarf planet" should have an orbit around the Sun.

国际天文学联合会的意见认为，&矮行星&应该绕太阳沿轨道运转。

Pluto is now classified as a "dwarf planet".

冥王星现在被归类为&矮行星&。

Ris is real, but it is a dwarf planet similar to Pluto that will remain in the outer solar system; the closest it can come to Earth is about 4 billion miles.

RIS倒是真实存在的，但它也只是一颗在太阳系外围活动的，类似于冥王星这样的矮行星。它与地球的最近距离也在40亿英里左右。

It is just weeks since Pluto was redefined as a dwarf planet.

从冥王星被重定义为矮行星之后仅仅几周。

This dwarf planet is further form the Sun than Pluto.

A planet on the other hand is built up out of the dust that surrounds a star. When a star is formed there is still a disk of gas surrounding it. As this gas cools, it condenses and forms solid grains. These grain particles accrete into large bodies called planetesimals, which then collide and accrete to make protoplanets. These protoplanets evolve into planets like the planets in our own solar system.

行星演化与恒星不同：恒星形成之后，周边的气体尘埃云冷却之后凝结形成，成为行星雏形，众多小行星雏形聚合碰撞，演化成成熟的行星；没有内部的核聚变；质量超过木星13.6倍，就会产生核聚变，如果还未至木星86倍，尚处于棕矮星的阶段，将会向恒星演化；持久的核聚变需要足够大的质量来支撑，温度也不足支撑氢向氦的转变。

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.

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。
