This essay explores using micosatellite DNAs to study the genetic diversity, and its major contents are as follows:The contrast among different methods of feces preservation: The methods are that feces was respectively stored in the field during collection at a low temperature after drying at 60 ℃, stored in 75% ethanol, stored in 100% ethanol and directly stored at a low temperature(in the attemperator added the biological ice bag),The result showed that DNA could be extracted successfully from the feces in a short storing period with any of these methods.

本文应用微卫星标记来研究普氏原羚遗传多样性，主要研究内容如下：一、不同普氏原羚粪便保存方法比较：通过将普氏原羚的粪便在野外分别采取60℃干燥后低温保存，75％乙醇保存，100％乙醇保存，直接低温保存。

Extracts with higher antioxidant abilities, including hot water and ethanol extracts of Boehmeria nivea leaves and roots, were screened and then added into soy bean oil to study effects on oil stabilities of oxidation during storage and also to develop new XO paste products containing Boehmeria nivea leaves and roots. The extents of oil oxidation in XO paste were evaluated by measuring POV and TBA values. Results indicated that after 8 day storage at 70℃, the POV values of soy bean oil with addition of 0.1% of ethanol extracts of leaf and root were 56.27± 0.12 meq/kg and 57.13± 0.50 meq/kg respectively, which were both greater than that of control samples(53.33 ±0.31 meq/kg), showing that extracts of leaf and root do not have the abilities to inhibit oxidation of soy bean oil.

第二部分将抗氧化能力较高的萃取物，包括苎麻叶与根的热水及乙醇萃取物添加於大豆油中，探讨其对油脂贮藏安定性之影响及开发加入苎麻叶或根的XO酱产品，并藉由测定油脂中过氧化价(peroxide value，POV)和硫巴比妥酸值(thiobar-bituric acid value，TBA)值评估其油脂氧化程度，结果贮存在70℃下第8天时，添加0.1 %苎麻叶与根乙醇萃取物，其POV值分别为56.27±0.12 meq/kg与57.13±0.50 meq/kg，皆较对照组(53.33 ±0.31 meq/kg)高，显示以0.1 %的苎麻叶和根萃取物添加大豆油中并不具抑制油脂氧化作用。

Many economists, consumer advocates, environmental experts and tax groups have been critical of corn ethanol programs as a boondoggle that benefits agribusiness conglomerates more than small farmers. Those complaints have intensified recently as corn prices have risen sharply in tandem with oil prices and corn normally used for food stock has been diverted to ethanol production.

很多经济学家，为消费者说话的人士，环保专家和税收组织都对玉米乙醇项目持批评态度，认为它实际只对农业巨头有利，对小农场主是没有益处的，最近随着粮价跟随油价一起上涨，这些批评之声更加严厉，因为很多玉米本来应该是产粮的，结果被用来生产乙醇了。
