Result The results showed that 34 compounds of the volatile oil were identified, which accounted for 90.10% of all. The main chemical compounds were camphene (10.030%), beta-pinene (8.826%), limonene (7.935%), caryophyllene (12.457%). The antibacterial experiments of the volatile oil showed that the volatile oil had antibacterial activities to Staphylococcus aureus, but had no inhibition against Escherichia coil and Rhodotorula glutinis.

结果］经毛细管色谱分析分离，共确认出其中34种成分，所鉴定出化学成分的质量占总量的90.10%以上，应用色谱峰面积归一法分析各成分的质量分数，其主要化学成分是莰烯(10.030%)、-β-蒎烯(8.826%)、柠檬油(7.935%)、丁子香烯(12.457%)；并发现其化学成分对金黄色葡萄球菌有较强的抑制作用，对大肠杆菌、红酵母无明显作用。

In order to improve interlayer pit mud fermentation, self-made pit mud fermenter was used and pit mud functional bacteria were supplied in each turn of fermentation. Such measures could evidently increase contact area between fermented grains and pit mud, enhance ethyl caproate content in fermented grains (enhanced by almost three times than before) with no adverse influence on liquor yield, and improve liquor quality. Its application could effectively settle the problems such as pit mud odor in liquor, difficult operation, recycle use and unsatisfactory effects etc.

采用自制夹泥发酵器和每轮补充窖泥功能菌的夹泥发酵法进行浓香型白酒生产，结果表明，该方法能明显增大糟醅接触窖泥的面积；提高糟醅中己酸乙酯等香味物质的含量，己酸乙酯的含量比对照糟醅增加了近3倍；不影响曲酒的出酒率；可明显提高曲酒的质量；有效地解决了窖泥易进入糟醅，使酒中出现明显的窖泥味、操作困难、难以循环使用、效果不明显等问题。

Fatty acids, more importantly, the positional isomers, were identified by applying equivalent chain length values based on even-chain saturated fatty acid methyl ester standards.

以线性程序升温等当碳长度值结合标准品对照的方法对17种脂肪酸定性，用面积归一化法定量。

Two methods to draw productive technical plane figures of cutting areas are developed in the paper:one is vector, by which surveying data are put into system and processed to calculate the area and closing error, and finally graphical file is established in vector format.
