合成物质

This paper presents a description of the brief synthesis of hexanoic acid 2-ethyl ester by new methods and its application. It takes two steps and 4.5 h to complete the synthesis of it.

己酸二乙氨基乙醇酯(DA 6)由美国科学家于20世纪90年代初首先发现的一种新型植物生长调节剂，具有高活性，低毒无污染、可与其它农化物质兼容的特点，它的合成与应用研究正日益受到人们的重视[1～7]。

Phospho-tungstic heteropoly(H3PW12O40) was prepared and its catalytic performance for synthesizing of ethyl hexanoate from hexanoic acid and ethyl alcohol were studied.

结果表明：磷钨杂多酸是合成己酸乙酯的良好催化剂，当酸醇物质的量比为1∶2.0，催化剂用量为0.5 g/0.1 mol己酸，甲苯为8 mL，反应时间为150 min时，酯化率可达97.2

He had synthesised it five years before, but had found it "uninteresting" and stopped.

最初的合成可追溯到5年前，只是后来发现这种物质&有点无趣&，他收手了。

This is a precursor to heparin, an important anti-clotting agent that has, at present, to be extracted from blood, rather than being synthesised.

这是肝磷脂的初期形态，一种重要的抗凝固剂，目前要获得该物质就不得不从血液中提取，而不是人工合成。

As the kernel of BPY system, advanced wet degradation technology of waste comprises delivering sorted degradable organic substances into reactor, charging steam to perform wet degradation reaction under certain temperature and pressure for 1-2 hours, killing pathogenic bacteria and grass seeds to eliminate odor, synthesizing partially degraded substances into humus material, and preparing wet-degraded material into commercial fertilizer.

具有领先性的湿解技术是BPY系统的核心。应用湿解技术处理垃圾，将经过分选的可降解有机物输送到反应器内，通入蒸汽，在一定温度、压力和有水存在的条件下进行湿解反应，1～2小时杀灭病原菌和草籽，消除恶臭，同时使有机物的各种组份得到降解，并使部分降解后的物质再合成为腐殖质。然后将经过湿解处理的物料制成商品肥。

The furthest along in development are the glucagon-like peptide-1 (GLP-1) drugs, which pack a triple whammy against the disease, stimulating insulin secretion, suppressing glucagon secretion, and inhibiting gastric emptying. The furthest along in its class is exenatide, a synthetic version of a GLP-1-like substance found in the saliva of the Gila monster. An open-label study reported at the meeting showed that about half of patients failing oral therapy achieved near-normal glycemic control when exenatide was added to their regimen.

最先进的研究是类高血糖因子胜-1（GLP-1）药物，这种药物对於疾病的药效高出三倍，可以刺激胰岛素分泌、抑制高血糖因子分泌和抑制胃清空，其中最先进的一类药物为exenatide，这是一种从希拉毒蜥的唾液所合成的类GLP-1物质，根据一项公开标示的研究显示，无法以口服治疗的患者中，有一半的患者在服用exenatide之后，其血糖接近正常值。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
