Sensory grade,TMA ,pH ,TVB-N and TBA were lower than blank test sample's ,but the difference was in-apparent;The impact on froze pickled carp's TMA, pH, TVB-N and TBA was limited.Yunhe lake has abundant fishery resource .However, little fish such as Culter erythropterus, Hemiculter leucisclu are apt to die owing to short fuse.

而比较腌制后的空白样和处理样，水分、粗脂肪、粗蛋白质、粗灰份、氯化钠含量全都非常接近；比较感官、TMA、pH、TVB-N和TBA测定结果发现，该四项指标处理样都低于空白样，但是彼此的差异不够明显，新鲜的蒜、姜和洋葱的直接添加进腌制液中，对低温腌制后的鲢鱼的TMA、pH、TVB-N和TBA影响有限。

In the case of Li, the γ-peak (nitrate and nitrite species on surface) of NO desorption increases, the intermediate N〓O desorbs at higher temperature. In the case of Ce, the α-peak (species on the 〓 acidic sites) of NO desorption decreases, and N〓O desorbs at lower temperature.

Based on the comparison of the infrared spectra of polyamide homologues, on the changes in the infrared spectra of deuterated and iodine-treated samples of polycaprolactam, and also on the observations of the infrared dichroism of drawn film , the main absorption bands of polycaprolactam in the region 400 cm(-1)-1400cm-1, which are rather structure sensitive, have been assigned as follows: 1370 cm-1 band-VC-N;, 1265 cm-1 and 1205 cm-1 bands-; 1170 cm-1 band-VC-N; 730 cm-1 band-γCH2 of (CH2)n w...

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_。

Results The body weight, visceral fat and body weight ration, as well as the levels of blood glucose, insulin, triglyceride, total cholesterol, LDL, and total FFA, were significantly lower in high fat-fed group than in control group (P.01). 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.
