Nor did they spat over trivia. If the Sina list is like the star-shining sky, there are uncountable grass-root bloggers like glamorous, kaleidoscopic grasslands. When a star shoot across the sky, there will be a big focus (metaphorically the huge blog clicks ) among many people who look up into the sky, but over time we could have sore necks, and we feel uncomfortable in our eyes after meteorites vanish into nothing. When we overlook a small garden or unknown grassland, Obscure as they might be and it might be too small for all people to see, but what we can get there is the tranquility, the aroma of the flowers, the singing of birds and the fresh air that makes us feel our oats.

如果说新浪博客百强排行榜是星光灿烂的天空，那么，成千上万默默无名的草根博主就是繁花似锦、茂草如毯的大地，星空中某颗瑰丽璀璨的恒星、或某粒骤然划过的流星，固然会引来众目仰望，但恒星看多了，脖子会疼，流星看过了，眼睛会酸；大地上某个普通的花园、某片无名的草坪，虽然一时难容太多人观赏，但花香养鼻，草色养眼，曲径通幽，健腿益心。

外在的微生物能够合成不寻常的氨基酸，比如异缬氨酸和叔亮氨酸这些只有在陨石中出现的氨基酸。

According to the studies of maskelynite and the mineral assemblages in the shock veins, it seems that the nowadays shock classifications of meteorites should be further modified.

根据对冲击变质主要压标熔长石性质的最新分析结果和陨石冲击脉体矿物组合研究的成果，指出现有陨石冲击变质分类的主要特点和某些不完善之处。

We suggest that the shocked meteorites could be classified into two groups; the group-A contains high-density phases, such as maskelynite and other high-pressure minerals; the group-B contains low-density phases, for instance diaplectic feldspar glass, molten glass and the assemblages of low-pressure minerals.

本文提出，陨石按照冲击变质特征可以划分为以下两类：一是含高密度相类，如熔长石和各种高压矿物；二是合低密度相类，如长石击变玻璃、低压熔融玻璃和低压矿物组合。

The work involves two of the seven known "nakhlite" meteorites (named after El Nakhla, Egypt, where the first such meteorite was discovered), and the celebrated ALH84001 meteorite that some scientists believe shows evidence of microbial activity on Mars.

他们研究了七个知名的透辉橄无球粒陨石（根据陨石第一次被发现的地名命名，在埃及的 El Nakhla）中的两个和著名的ALH84001陨石（一些科学家认为这颗陨石反映了火星上的微生物活动）。

Dhofar 1180 is a unique lunar meteorite that differs petrographically and geochemically from all other lunar meteorites and lunar samples.It comes from a region on the lunar surface that has not been sampled by any other known lunar rocks.

Dhofar 1180的矿物学、岩石学和微量元素地球化学特征与已知的月球陨石和月岩样品有明显的差异，它来自月球表面的一个新的未知地区。

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.
