To investigate the effect of high temperature treatment on essential oil in fennel ,fruit of fennel was held at three temperature(40 ℃,60 ℃,80 ℃) and 25 ℃ for 7 days,then extracted essential oil and identified components by GC/MS.

结果表明：随着温度的升高，精油含量与主要成分的相对含量均呈先升高再降低的趋势，其中精油含量依次为0.93、3.04和3.17和1.51ml。

The content and composition of Germanic great fennel essential oil obtained by simultaneous distillation and extraction were investigated at three different time during distillation.

以德国大茴香为实验材料，采用同时蒸馏萃取法，分3个蒸馏时段研究了茴香精油的得率及精油成分的相对含量。

Neck care products suitable for the active ingredients are orchid oil, fennel essence, ginseng essence and so on, they have anti-oxidant, moisturizing and revitalizing the role, but also easy to cause skin allergies.

适合颈部护理的产品有效成分有兰花油、茴香精、人参精等，它们具有抗氧化、保湿及赋活的作用，而且不易引发皮肤过敏现象。

There was obviously negative revelance between essential oil and content of full nitrogen, proteinic nitrogen. In a word, 1n concentration N,P,K was fit to improve quality and yield of essential oil of fennel, increasing or decreasing concentration of N,P,K all decreases them.

以提高茴香精油产量和品质为目的的栽培应以标准配方的氮、磷、钾浓度来施肥，增加或减少它们的浓度都会导致精油产量和质量的降低。

Extracted plant essential oil from Ferula sinkiangensis K. M. Shen, Cumimum cyminum and Trigonella foenum-graecum by method of wet distillation and researched the repellent effect to Tribolium castaneum.

方法］采用水蒸气蒸馏法，从阿魏、孜然粉、香豆粉中提取植物精油，并研究了不同浓度植物精油对赤拟谷盗的趋避作用。

In this thesis we carried on the preliminary study to the extraction process of plant essential oil, and measured the biological activity of plant essential oil on red flour beetle, Tribolium castaneum and the housefly, Musca domestica vicina.

采用三因素四水平正交试验设计对植物精油进行提取工艺研究，最佳提取工艺条件是A_2B_3C_3，即50g供试植物加入1000ml水，水蒸气蒸馏120min后，用石油醚萃取，萃取液浓缩以后得到的精油可获最大收益。

Considering the problems of spurgear precise plastic forming, such as high deformation resistance, poor flowability and especial hardness to fill cant of gear, technological plan was developed based on precise plastic forming technique, successive control principle and consecutive local deformation theory. Moreover, structures of the rolling preform die and the die with up and down wellrounded forcer for stamping-extrusion and bulge-extrusion combining forming were designed too.

因此本文的主要研究内容和结果如下：本文以某种直齿轮：模数m＝2，齿数z＝20，压力角α＝200，变位系数x＝0为对象，针对直齿轮精密塑性成形变形抗力大，流动性差，特别是成形中齿轮角隅部分更加难以充满问题，基于精密塑性成形技术、逐次控制原理以及连续局部变形原理提出了"直齿轮滚轧制坯－镦挤、胀挤复合精成形"的工艺方案，设计了滚轧制坯的模具结构和上下冲头带圆角的镦挤、胀挤复合精成形的模具结构。
