In the ESI+ mode the compound isolated from fraction III/9 showed a pseudo-molecular ion of m/z 261 ([M + 1]+) as well as sodium and potassium adducts with m/z 283 and m/z 299, respectively, thus suggesting a molecular mass of 260 Da.

在 ESI+模式下，从子馏分 III/9中提取出来的化合物分别出现了伪分子离子 m/z 261 ([M + 1]+)和纳钾加合物 m/z 283 and m/z 299，这样就暗示了260 Da 的分子质量。

Accordingly, as catalyst of light oil sweetening,the binuclear cobalt sulfonate phthalocyanine was selected in this paper. Due to the double active centers in a plane, bi-CoSPc not only increases the solubility in alkaline, but also avoids its dimerisation, which expects to increase the catalyst activity in sweetening process.

为此，本文选用双核酞菁钴磺酸盐作为轻质油品脱臭催化剂，该催化剂具有平面双核的分子结构，这不仅增加了其在碱液中的溶解度，同时也减弱了二氧加合物的形成趋势，有望在轻质油品催化氧化脱臭工艺中具有更高的催化活性和使用寿命。

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.
