根据对聚酰胺类高聚物红外光谱的类比和对聚酰胺6试样进行氘化和碘处理后红外光谱的改变，以及根据对拉伸过的聚酰胺6薄膜试样的偏振红外光谱的观察，我们对聚酰胺6红外光谱中400cm~(-1)—1400cm~(-1)之间的主要吸收带，作了如下解释：1370cm~(-1)吸收带为ν_；1265cm~(-1)和1205cm~(-1)吸收带为δ_+ν_；1170cm~(-1)吸收带为ν_；730cm~(-1)吸收带为γ_(CH_2)[当(CH_2)_n的n≥4时]；690cm~(-1)吸收带为δ_；580cm~(-1)吸收带亦为δ_。

The aortic tunica intima was intact, the number of foam cells was decreased, and inflammatory cells infiltrated into the med-intima smooth muscle of the n-3 PUFA group. However, with no such changes were observed in control and n-3 PUFAs groups. Little or no expression of NF-κB, ICAM-1 and MCP-1, and a high expression level of IκBα were detected in aortic tunica intima of the n-3 PUFA and control groups, while high expression levels of NF-κB, ICAM-1 and MCP-1, and little expression of IκBα were detected in aortic tunica intima of the high fat-fed group.

结果 n-3脂肪酸组大鼠体重第1~11周均明显降低，空腹血糖、血清胰岛素、TG、TC、LDL-C、总FFA和内脏脂肪占体重百分比均明显低于HF组，HDL-C则明显高于HF组，与对照组无明显差别；n-3脂肪酸组大鼠主动脉主动脉内膜完整无内皮细胞脱落现象，内膜下泡沫细胞及炎细胞浸润减少，内膜的NF-κB呈弱阳性表达，IκBα呈阳性表达，ICAM-1和MCP-1均呈阴性或弱阳性表达。

The maintenance of a yield level of 1000 Kg longan fruits per 667 m2 growing on the red soil hilly lands of south Fujian could refer to the following fertilization program, namely, N, 20～25 Kg N of organic fertilizer making up 40 percent of the total N fertilizer

There was an obvious effect of different N, P and K application rates on N, P, K concentration of stem, leaf, rhizome and total ginger plant in each growth period, the uptake and accumulation of nutrient and distribution increased greatly. Ginger in the treatments of moderate fertilizer application rate of N450, P120 and K450 had a higher N, P and K concentration, which resulted in the increase amount of nutrient uptake and accumulation.

施用不同数量的氮磷钾对各生育期生姜茎、叶、姜各部位及全株N、P、K含量和养分吸收积累量、养分分配有明显影响，中等施肥量的N450、P120和K450处理在整个生育期含N、含P和含K量均较高，养分吸收量和积累量显著增多。
