Nowadays chemosynthesis pigment is used mainly. Along with the problem of food safety is concerned, the application of chemosynthesis pigment is limited.

目前常用的色素主要是化学合成色素，随着人们对食品安全问题的关注，国内外已很大程度上限制化学色素的使用。

We adopt chemosynthesis and template assembly choosing different templates and different approach to change the sizes and structures of nano-micron porous materials and realize the regulation of new materials'' structures and physical properties, hunting the feasibility and application foreground of composing devices.

我们采用化学合成的方法，用模板组装的技术，选择不同的模板及不同的合成路线，改变纳、微孔径的尺寸和孔结构，实现新材料结构与物性的调控，探求组成器件的可行性及应用前景。

As a nature biosynthesis gum,xanthan gum is much more environmental friendly than chemosynthesis gum

同时，由于黄原胶是一种纯天然的生物合成胶，与其他化学合成胶相比更具有环保性。

The method of photocatalysis with TiO_2 catalyst is not only used in the filed of dealing with pollutants, but also has some potential in the field of chemosynthesis because it is usually employed at normal temperature and normal pressure for chemosynthesis without second pollutants.

以TiO_2为催化剂的光催化法不但已经应用于环境污染处理领域，而且也开始在化学合成领域逐渐显示潜力，这无疑会给化学工业带来新的憧憬，因为光催化合成通常在常温常压进行，易操作，一般不会产生二次污染。

According to the results described above, we try to synthesize the long peptide chain of Lys fragment to prove these results and also to get enough sample to do X-ray and 2D NMR analysis.

根据上述结果我们试图对长链26肽进行化学合成，一方面从合成角度进一步证实以前的结果；同时为了得到足够的样品进行晶体结构或二维核磁共振的研究。

Methods: In this paper, a quinazoline purine analogues for the parent nucleus, respectively, and four of its seven introduced to replace the structure of diverse and flexible side-chain amino-benzene, design a series of 4 - to replace the aniline-based -6 - methoxy --7 -(2 - hydroxy replace C oxy) quinazoline compounds.

目的：通过各种化学合成方法完成目标化合物4--6-甲氧基-7-(2-羟基取代丙氧基)喹唑啉的合成并对目标化合物进行结构修饰，以期获得高活性的表皮生长因子受体酪氨酸激酶抑制剂。

According to the spetial conformational analysis and physical/chemical property analysis and by the aid of computer it can make molecular design of mimic polypeptide and designs the polypeptide molecule with activity for neutralizing LPS, and adopts the solid phase polypeptide chemical synthesis method to synthesize antibacterial/antiendotoxin mimic peptide with total or partial BPI bio-function.

本发明公开了通过计算机模拟设计、人工合成的66个抗菌／抗内毒素模拟肽，根据对BPIN端三个LOOP区的空间构象分析及物理化学性质分析，在计算机辅助下进行模拟多肽的分子设计，设计出具有中和LPS活性的多肽分子，用固相多肽化学合成方法合成抗菌／抗内毒素模拟肽，本发明的抗菌／抗内毒素模拟肽具有全部或部分BPI的生物功能，可以用于治疗G－细菌感染、人内毒素血症，具有分子量小、可以稳定重复生产的特点。

Peptides are traditionally synthesized in liquid phase, such methods are DCC, mixed anhydrides, acyl chloride and azide etc., which provide more choices for peptides synthesis.

传统的肽类合成多采用液相化学合成，常用的包括碳二亚胺法，混合酸酐法、酰氯法、叠氮物法等等，为多肽的合成提供了多种选择。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
