These fats usually contain less than 20% saturated fatty acids, with oleic and linoleic acids being dominant.

这些油脂含饱和脂肪酸通常低于20%，且以油酸和亚油酸为主。

The increase of salt content improved the production of palmitic acid and linoleic acid, but reduced that of oleic acid. The influence of salt content on stearic acid and linolenic acid was not singnificant.

土壤含盐量的增加，促进棕榈酸、亚油酸的生成，抑制油酸的生成，但硬脂酸、亚麻酸的变化受土壤盐含量的影响不明显。

The weight of oil and fat producing by fusants was 48.5% of dried cell. Palmitoleic acid was 47.29% of total oil and fat , which accounted for 22.95% of dried cell.

产脂和产棕榈油酸分析表明，融合子的产脂量为菌体干重的48.53%，其中棕榈油酸占油脂总量的47.29%，为菌体干重的22.95%。

Of them,the percentagefalling of palmitoleic acid was most significant(P＜0.01),the percen-tage falling of oleic acid was slow.

其中以棕榈油酸含量下降最为明显，油酸下降较少。

QUALITIES:Feels similar to coconut oil. It is fine, clear to cloudy and odourless. King of nuts, sometimes known as the vanishing oil, as it absorbs very quickly into the skin. Contains around 58% oleic and 21% palmitoleic acids, is an excellent emollient, and particularly good for dry or wrinkled skin. Macadamia oil may help in the fight to prevent premature aging of skin.

特性：感觉和可可油类似，澳洲坚果是坚果之王，有时也被称为&正在消失的油&，由于它含有大约58%的油酸和约21%的棕榈油酸故能迅速的进入皮肤，是一种优质的润肤剂，尤其对干燥或出现皱纹的皮肤特别好，澳洲坚果油能很好的防止皮肤过早老化。

High palmitoleic acid-producing strains were obtained by protoplast fusion between Saccharomyces cerevisiae No.12.926 producing palmitoleic acid and Rhodotorula No.12.908 producing oil and fat.

采用原生质体融合技术进行产棕榈油酸酵母Saccharomy cescerevisiaeNo.12.926和产脂酵母RhodotorulaNo.12.908的融合研究，获得了棕榈油酸高产酵母工程菌株。

The optimum conditions were obtained as follows: the weight ratio of fatty acids and 85%acetic acid is 1:4, ozonolysis temperature is 20-25℃, manganese/copper acetate as catalyst, and the amount of catalyst is 0.15% of fatty acids, oxidation decomposition temperature and oxidation decomposition time are 90-95℃ and 4 hours respectively. the yields of azelaic acid and pelargonic acid are 57.4% and 51.6% respectively.

以菜油酸为原料、85%醋酸水溶液为溶剂，经臭氧化、氧化分解、重结晶等过程制备壬二酸和十三烷二酸的最佳反应条件为：m：m(85%醋酸)=1：4，臭氧化温度20-25℃；氧化分解温度80-85℃，催化剂醋酸锰/醋酸铜用量为原料菜油酸质量的0.12%，氧化分解时间3h，重结晶溶剂壬酸的用量为5倍质量的氧化分解产物时，十三烷二酸的收率为58.3%，壬二酸的收率为57.2%。

Factors were reviewed, and optimum conditions was obtained,these experiments provide effective data for industrial manufacture.On the condition of using fatty acids of cottonseed oil as raw material,85% acetic acid as solvent,this paper prepared azelaic acid and pelargonic acid by ozonolysis, oxidation decomposition , extracted by boiling water,active carbon absorpting etc.

以棉油酸为原料、85%醋酸水溶液为溶剂，经臭氧化、氧化分解、沸水萃取、活性炭吸附脱色等过程制备壬二酸的最佳反应条件为：m：m(85%醋酸)=1：4，臭氧化温度20-25℃；氧化分解温度90-95℃，催化剂醋酸锰/醋酸铜用量为原料棉油酸质量的0.15%，氧化分解4h，壬二酸收率为57.4%，壬酸收率为51.6%。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
