The results showed that among the main saturated fatty acids,palmitic acid content keeps the highest,myristic acid content was in the middle,and lauric acid content was the lowest.

在不饱和脂肪酸中，亚麻酸的含量最高，亚油酸的含量次之，油酸含量略低于亚油酸。亚油酸含量表现为随生长期延长而降低；亚麻酸含量在7月达到最大累积，随后急剧降低。

In the adipose tissue of obese pigs,the percentagesof myristic acid(C14:0),linoleic(C18:2)and linolenic acid(C18:3)were lower(P＜0.01),and that of palmitate(C16:0)and stearic acid(C18:0)were higher(P＜0.01),the percentages of the total SFA washigher,and that of total UFA and total PUFA were lower,than thatof lean lean pigs respectively.

肥胖型猪脂肪中豆蔻酸、亚油酸和亚麻酸含量较低(P＜0.01)，而棕榈酸(C16：0)和硬脂酸(C18：0)含量则较高。含量最多的油酸差异不明显。从各类脂肪酸总量来看，脂肪型猪的SFA含量较高，而UFA和PUFA含量较低(P＜0.01)。尤其是PUFA的差异最为明显。并进一步探讨了这种差异对脂肪最终品质的影响。

The results showed that the niobic acid treated with the other acid had obvious crystal structure and higher surface acid strength.

Methods: After the sorting and analysis of data in the physical examination of 4640 cases, the comparisons between the BMI and blood lipid, the levels of blood sugar and hematuria acid were compared in the groups according to sex and age. The levels of blood lipid, blood sugar and hematuria acid were compared in the fatty and nonfatty groups according to BWI. The levels of blood lipid, blood sugar and hematuria acid were also compared in the two groups according to sex and BWI.

对4640例体检者检查资料进行整理分析，按性别、年龄分组，比较体重指数与血脂、血糖和血尿酸的水平；按BMI分为肥胖组和非肥胖组，比较两组之间血脂、血糖和血尿酸的水平；进一步按性别和BMI比较两组之间血脂、血糖和血尿酸的水平。

The results were as follows the change of vitamin C content was a "trial apex"-shape curve, higher in young fruit,incrustation and maturation stages, lower in other periods; the total acid content was the highest in young fruit, after that, it decreased rapidly, maintained lower level, and reached lowest when the fruit matured; the total content of soluble sugar inosculated with the fruit development, it was high when the fruit development was quick, and low when the fruit development was slow; before 59 d after anthesis, the reducing sugar content was high in the total content of soluble sugar and after that ,the nonreducing sugar content was high; before 45 d after anthesis, free amino acid content was obviously correlated with protein content, and they inosculated with the fruit development;4559 d after anthesis, free amino acid content increased quickly, and protein content decreased gradually, this was also the most shaping period of the embryo and endosperm.

结果表明，Vc含量呈&三峰&型曲线，幼果时、硬核后和成熟时较高，其他时期较低；有机酸含量以幼果期最高，以后迅速下降并维持较低水平，果实成熟时含量最低；可溶性总糖含量与果实发育状况基本相吻合，果实发育速度快时含量较高，慢时较低；在谢花后59 d以前，可溶性糖以还原糖为主，之后以非还原糖为主；游离氨基酸和蛋白质含量，在谢花后45 d以前两者呈高度相关，且与果实生长速度相吻合，谢花后4559 d是胚和胚乳的主要形成期，此期游离氨基酸含量迅速增加，蛋白质含量持续下降。西北林学院学报21卷第5期张传来等金光杏梅果实发育期间主要营养成分动态变化研究
