采用自制薄膜球盘磨损试验机，研究用IBAD技术制备碳膜的碳膜的摩擦学性能，并与CrN Cu膜进行对比。

When you start up on a very low carbohydrate diet such as Atkins or a Ketogenic diet you enter into what is referred to as ketosis where your body switches from running on carbohydrates as fuel to using a source called ketones.

当你开始每天食用低碳水化合物的食品例如减肥专家或者生酮膳食，也就和糖尿病酮症患者的饮食差不多了，即本来以碳水化合物为身体主要能量变成依赖酮体作为身体能量。

On the other hand, reaction of lactol derived from D-mannose and D-glucose with Grinard reagent of propargyl bromide also proceed both withanti stereoselectivity and with high anti-specificity.

链增长及目标分子中的碳碳双键是由一步Wittig反应和一步末端炔的烷基化再部分氢化而获得，双键构型-选择性可达到95％以上。

Carbohydrate contents were determined to study the carbon metabolism in bulbs of Lilium Oriental hybrid Sorbonne'.

本文通过测量不同发育时期的碳水化合物含量来研究东方百合&Sorbonne&的碳代谢。

Based on the results of 1H-NMR, 13C-NMR, ESI-MS and UV spectra, the structures of three compounds with antitumor activity were identified as Prodigiosin、7-Hexadecenoic acid、7,10-Octadecadienoic acid, respectively; another compounds (no activity to above tumor cells)was identified as Myristic acid.

运用核磁共振（1H-NMR、13C-NMR）、质谱、紫外光谱等现代波谱技术分析，将其中3种具有抗肿瘤活性的化合物分别鉴定为灵菌红素、7-十六碳烯酸（7-Hexadecenoic acid）、7，10-十八碳二烯酸（7，10-Octadecadienoic acid）；鉴定另一种对上述肿瘤细胞无活性的化合物为肉豆蔻酸。

This paper describes the determination on the activity of carbonic anhydrase (CA,EC4.2.1.1) of plant species in karst areas of Southwest China. CA was extracted from leaves of Vitex negundo. The thermostability of CA and the effects of anions and metallic ions on CA activity were investigated.

研究表明西南岩溶地区几种植物叶片中含有明显活性的碳酸酐酶(carbonic anhydrase， CA)，从黄荆叶片提取碳酸酐酶，该酶具有良好的热稳定性。

The result indicated that octadecyl isocyanate was successfully introduced onto the surface of the MWNTs,and the dispersion of nanomaterials was thus improved.

结果表明，在MWNTs表面成功地接枝上含有十八个碳原子的小分子，有效提高了碳纳米管在溶液和基体聚合物中的分散性，这种烷基化处理相对简单、廉价。

Unsaturated fatty acids including linoleic acid、γ-linolenic acid、 dihomo-γ-linolenic acid、 arachidonic acid and eicosapentaenoic acid have played important roles in prevention and treatment of heart disease and high blood pressure、 in the inflammatory area (for example, treatment of asthma、 arthritis and psoriasis) and for some cancer treatment Natural sources of UFAs are animal and plant, such as EPA in fish oils, arachidonic acid in porcine liver and y -linolenic acid in Oenothera biennis L..

不饱和脂肪酸包括亚油酸、γ-亚麻酸、双高γ-亚麻酸、花生四烯酸和二十碳五烯酸等在内对心脏疾病、高血压、炎症(如哮喘、关节炎和牛皮藓)和某些癌症的预防和治疗均有显著效果。不饱和脂肪酸的自然来源主要是动植物，如二十碳五烯酸存在于深海鱼油，花生四烯酸存在于猪肝而γ-亚麻酸多来源于月见草等植物种籽。

The empirical rule governing the position of double bonds in olefinic acids was referred to by analyzing electron impact spectra of the chemical products modified by 2-amino-2-methylpropanol of the fatty acids. This method provides a new technical tool for analyzing fine structures of unsaturated fatty acids.

通过解析不饱和脂肪酸2-氨基－2-甲基丙醇化学修饰产物的EI质谱图，得到了不饱和脂肪酸中碳碳双键的定位规则，从而为分析不饱和脂肪酸精细结构提供了手段。
