Based on the ratio of the minerals, the team reports in tomorrow's issue of Nature that CO2 levels during the Archean could have been no higher than about 1000 parts per million—about three times the current level of 387 ppm and not high enough to compensate for the weak sun.

根据两种矿物的比例，研究小组在明天出版的《自然》杂志上报道说：在太古代期间，二氧化碳的水平决不会高于大约百万分之一千（1000ppm）——大约三倍于目前的水平（387ppm），不足以弥补阳光的弱势。

Applied conductance law is kinetic to reaction of bee glue enzymatic catalysis undertake study, result discovery, in bee glue - in enzymatic system, be in without oscillation phenomenon; bee glue - enzymatic - inside NaCl system, electrical conductivity lifts quickly, appeared only 3 more apparent fluctuant peaks, accumulate period longer, it is 10~20 Min about, accumulate period afterwards, electrical conductivity lifts quickly reduce quickly again, fluctuant and gently; is in after 40 Min bee glue - enzymatic - inside KCl system, response is quick, oscillation period is 20 Min about, the wave motion after 30 Min is slow till platform reacts,stop.

应用电导法对蜂胶酶催化反应动力学进行探究，结果发现，在蜂胶-酶体系中，无振荡现象；在蜂胶-酶-NaCl体系内，电导率急剧升高，只出现了3个比较明显的波动峰，积累期较长，大约为10~20 min，积累期过后，电导率迅速升高又迅速降低，40 min后波动平缓；在蜂胶-酶-KCl体系内，反应迅速，振荡期大约为20 min，30 min后波动缓慢直至平台反应终止。

This formation once occupied only about 5 percent of the country, but has now expanded, largely as a result of fire disturbance, to cover some 4,400 km , or 23 percent of New Caledonia.

由於火干扰，一次被占领的这种形成仅大约国家的5%，但是现在扩展，主要，包括大约4，400 km 或者新卡里多尼亚的23%。

Successful treatment is dependent on an accurate diagnosis of the cause of ascites; e.g., peritoneal carcinomatosis does not respond to diuretic therapy.

病史美国多数腹水患者（大约85%）有肝硬化（表2）10，有大约15％的腹水患者，是由于非肝源性原因引起的体液潴留，对腹水患者的成功治疗取决于准确的腹水病因的诊断；例如利尿剂治疗对腹膜恶性肿瘤没有效果。

Much of the gas in the disk of the Circinus spiral is concentrated in two specific rings -- a larger one of diameter 1,300 light-years, which has already been observed by ground-based telescopes, and a previously unseen ring of diameter 260 light-years.

在圆规座的漩涡星系中的大部分气体都与两个具体的"环"有密切的联系。那个较大的，直径大约有1，300光年，它已经被地基望远镜观测到了。而先前，我们没有观测到的那个小"环"，直径大约有260光年。

After about sixty days, LRO will enter its operational circular polar orbit, about 31 miles above the moon's surface.

经过大约在60天LRO将进入月球极低轨道，大约处于月球表面31英里。

I am therefore compelled to conclude that the actual final lot of the Chinese working class is inextricably bound with British history firstly with the Industrial Revolution and then with the development of the theory of the Revolution of the Proletariat.

目前我已经收集了大约150个下岗工人的"声音"（实际上是他们在讲述他们自己的故事），因为GRAIN艺术展的声音播放的时间是2小时，所以我会精选30个工人的声音（每个声音大约5分钟）连接在一起，作成一个声音文件，在GRAIN艺术展现场播放。

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。
