本文利用光谱和电化学方法研究了儿茶酚胺衍生物与小牛胸腺DNA之间的作用机制。

Percentage of dressing, eviscerated carcass decreased significantly as dietaryω6/ω3 was reduced; percentage of abdominal fat, subcutaneous fat and intermuscular fat were higher in birds fed lower ratio diets. Drip loss in both breast and thigh muscle increased significantly in birds fedω6/ω3 ratio from 18 to 2.6. Except b* value in breast muscle decreased as birds fed dietary ratio from 5 to 2.6, the tendency for breast and thigh muscle were almost similar; a* values progressively increased as the diets contained increasingω3 content, changes in b* were also significant but the pattern was almost the reverse for changes in a*. Decreasing the dietaryω6/ω3 clearly increased the contents of ALA, EPA and DPA, but not for DHA.

结果表明：①饲喂10：1的日粮显著增加6周龄AA鸡的体重和日采食量；②随着日粮ω6/ω3比值的降低，屠宰率和净膛率显著下降；低ω6/ω3比值的日粮增加腹脂率、皮下脂肪和肌间脂肪；③日粮ω6/ω3比值从18下降到2.6时，胸、腿肌滴水损失显著下降；除日粮比值从5降到2.6时胸肌b*值下降外，胸、腿肌变化规律相似，a*值和b*值变化趋势相反：a*值下降，b*值上升；④日粮ω6/ω3的降低，ω3 PUFA中ALA、EPA和DPA显著增加；⑤肝脏中ALA含量低于胸肌，而其长链衍生物C20：3、EPA和DHA的含量则是肝脏中含量较高。

Last, but certainly not least, we can understand the fork— and its spinoffs, the dessert fork, the salad fork, and the oyster fork— as part of that efflorescence of the inutile that always accompanies the rise of new money.

最后，也是非常重要的一点，我们可以把叉子———包括其衍生物如甜点叉、拉叉以及牡蛎叉等———看作是总伴随著新生财富出现的浮华风尚的一部分。
