碳极

By analyzing the ratio of carbon-14 to nitrogen-14, researchers can determine, within a narrow margin, when the sample in question last breathed or photosynthesized .

通过分析碳14和氮14的比例，研究人员能够以极小的误差确定被研究的标本最后进行呼吸的时间或最后进行光合作用的时间。

At present, much attention had been paid to the study of the surfactants with four coordinate boron oxygen heterocycles structure, however, the main work was focused on the synthesis of the surfactants containing boron with short-carbon chain alkyls and their basic properties.

目前研究的方向主要是含四配位硼氧杂环结构的表面活性剂，但都是对一些含短链烷基的合成和基本性质研究，对含长碳链的还极少见文献报道。

Designed for comprehensive songbird, targeted micro-particles, palatability strong, selected high-quality animal meat meal, insect powder and fish meal as the main source of high-protein, whit the necessary bird body fat, carbohydrates, complex minerals, vitamins, but also add lactic acid bacteria and digestive enzymes, effectively improve the utilization of food nutrients to help digestion and resistance to pathogens, long-term feeding to ensure a robust body of birds, feathers bright, will enhance the degree of song.
