The main compositions were trans-β-farnesene,β-pinene, caryophyllene oxide, spathulenol, nerolidol, which were much different from other Compositae plant.

主要成分为反式-α-香柠檬烯、β-蒎烯、石竹烯氧化物、匙叶桉油烯醇、橙花叔醇等，其主要成分与菊科其他植物的明显不同。

Results:The experiments showed that 59 components were identified,accounting for 72.91 percent of the total essential oil.The essential oil was mainly composed of dehydrocostuslactone、costunolide、cedrenol、α-elemene、1,3-cyclooctadiene、eudesmol、α-selinene、β-caryophyllene、-longifolene、3,4-octadiene,7-methyl-etc.Among them Lactones like Dehydrocostuslactone and costunolide are essential components.

结果：GC-MS法分析鉴定了木香挥发油中59个成分，其主要成分为去氢木香内酯、木香烃内酯、雪松烯醇、α-榄香烯、环辛二烯、桉叶醇、α-芹子烯、丁子香烯、长松叶烯、7-甲基-3，4辛二烯等，占挥发油总量的72.91%；首次发现木香挥发油及去氢木香内酯、木香烃内酯具有抑制ADP诱导的血小板聚集活性。

From biolinguistic perspectives,the author proposes that besides thematic information,categorial information plays a key role in determining the order of merge within VP and that structurally complex complements should be merged before simple ones.

本研究发现，除语义信息外，语类信息在决定VP内各成分合并顺序方面发挥关键作用。成分结构的复杂程度对合并顺序的影响说明，生物学因素，如人类语言机能的处理能力、活动记忆的容量等对语言生成发挥重要影响，是语言研究不可忽视的因素。

Celangulins is a novel botanical insecticide from Chinese traditional insecticidal plant, Celastrus angulatus Max.

是我国著名的传统杀虫植物，基于其中杀虫活性成分开发的植物源杀虫剂苦皮藤素已获得了3项中国发明专利，6β-丙氧基苦皮藤素Ⅴ是近年来通过苦皮藤素Ⅴ衍生合成得到的毒杀成分。

Now, Flavonoids and ginkgolides were mainly extracted from the leaves of Ginkgo biloba., but the leaves often contain high content of corious and cereous, and the effective constituent is very different under the various conditions. In addition, the constituent of ginkgolides is very low in the leaves, and thus the quality of extraction is difficult to reach the international standards.

目前人们主要从银杏叶中提取银杏黄酮和萜内酯，但由于银杏黄酮和银杏内酯的含量很低，尤其银杏叶中最主要的有效成分银杏内酯B主要存在于根中，在银杏叶中含量极低(＜0.1％)，且是在生长状态的叶中含量最高，采叶影响树的生长；又因银杏叶中主要的有效成分受多种因素的影响又有很大差别，银杏叶革质化、蜡质化程度高，使得国内银杏叶提取物的质量很难达到国际标准。

To study aroma characteristics of Chaenomeles fruits and expand developing channels of Chaenomeles industry, aroma components of three different cultivars of Chaenomeles fruits were extracted with the method of Simultaneous Distillation and Extraction and identified by GC-MS.

为了深入了解木瓜的香气特征，扩大木瓜的开发利用途径，采用同步蒸馏－萃取法对长俊、狮子头、玉兰3种木瓜果实的香气成分进行了提取，并用GC-MS分析了3种木瓜果实香气成分的组成。

Aqua, Rosa Damascena Flower Distillate, Hydrogenated Jojoba Oil (solid jojoba beads which do not break down or disperse on the skin), Sucrose Cocoate, PEG-60 Almond Glycerides, Aloe Barbadensis Leaf Extract, Camellia Oleifera Leaf Extract, Chamomilla Recutita Extract, Glycerin, Disodium EDTA, Carbomer, Benzophenone-4, Triethanolamine, Imidazolidinyl Urea, Methylparaben.

和上面的洁面完全是一样的清洁体系，有效成分也是那几个，唯一的不同是有霍霍芭颗粒做磨沙介质和霍霍芭油，基本上没有太大区别，如果硬是要挑毛病，建议mir换个不透光瓶子，就可以把Benzophenone-4这个保护产品的防晒剂去掉了，不过在清洁产品中这个成分没有太大的风险。

Our study was to analyze the chemical constituents of volatile oil from Chenopodium ambrosioides L.. The volatile oil was extracted by steam distilation.

采用水蒸气蒸馏法提取土荆芥挥发油，应用GC-MS对挥发油成分进行分析鉴定，鉴定了挥发油中的12种化学成分。

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。
