近20年由於「气相同位素比值质谱仪」的改良和氢、氧、碳、氮和硫等稳定同位素的广泛研究，稳定同位素的研究技术已实质增加我们对於这些元素在自然生態系中生地化循环的瞭解。

And you need torches using oxygen to get hot enough - a regular Bunsen burner or even a "MAPP" gas blowtorch from a hardware store is not hot enough.

并且你需要使用氧喷枪来获得足够的热量--普通的气焊不顶用。

In the northeast part of the South China Sea the high salinity water comes from the Philippine Sea, therefore, biologic productivity was high and there was rich organic matter in sediments during the periods of oxygen-isotopes 2, 4 and 6. In these periods the sedimentation rate was very high, so there were very good material conditions for formation of gas hydrate. In addition, from the end of Miocene to present, the Philippine Sea plate collided with Asian plate in Taiwan area, extruding the northeast part of the South China Sea along northwest direction. The extruding force made fluid in the sediments very active, and this is very good for the formation of gas hydrate.

南海冻北部，在氧同位素2、4、6期，由于菲律宾海的高盐度海水的注入，使这里的生物生产率特别高，陆坡上沉积了丰富的有机物质，加上此期间该处的沉积速率高，为天然气水合物的生成提供了物质条件；另外，自中新世末以来，由于菲律宾海板块与欧亚板块在台湾地区发生碰撞，对南海北部产生北西向挤压，加快了流体在沉积物中的活动，为天然气水合物的生成提供了良好的构造环境。

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.
