Refrigeration of boiled water nature comes to 20 ℃ when 25 ℃, before the gas of deliquescent amid compares boiling, decrease 1/2 the left and right sides, water quality also produces change subsequently, cohesive force increases, between element and element more close together, exterior tension is strengthened.

开水自然冷却到20℃至25℃时，溶解在其中的气体比沸腾前减少二分之一左右，水质也随之发生变化，内聚力增大，分子与分子之间更加紧密，表面张力加强。

Furthermore, a theoretical Molecule-In-Molecule approach was used to rationalize the excited state delocalization pathway of cyclophandiene molecules.

透过分子内分子(Molecule-In-Molecule)的方法，可以进一步解环芃二烯在激发态非定域化的途径。

Second, guanidine chloride is another important denaturant used commonly for protein unfolding. It is believed that guanidine chloride and urea have a similar mechanism of action.

其次，盐酸胍是常用于使蛋白质变性的另一种重要变性剂，盐酸胍分子与蛋白质分子相互作用的机理和尿素的情形具有相似性。

PCR is one of the common techniques in molecular biology, which can amplify nucleic acids through the cycle of denaturation, annealing and extension.

PCR是最常用的分子生物学技术之一，通过变性、退火和延伸的循环来完成核酸分子的大量扩增。

The mechanism of protein precipitate was mainly described to the denature agglomeration of proteins which then developed macromolecular proteins with their molecular higher above 10,000 （proteins with molecular weight between 10,000～5,000 easily produced precipitates）.

黄酒蛋白质的沉淀机理主要是由蛋白质的变性团聚，产生分子量大于10000的蛋白质分子，分子量在10000～5000的蛋白质分子易使黄酒形成沉淀；酒体中的多酚、金属离子、乙醇也会引起蛋白质沉淀。

Generally, B in the configuration closest cell's DNA conformation, it and the double helix model are similar. A-DNA and when RNA member double helix area as well as duplication forms the DNA-RNA hybrid molecule conformation is close. Z-DNA take the nucleotide dimer as the unit left-hand winding, its principal chain assumes the denticle the shape, therefore.

一般认为，B构型最接近细胞中的DNA构象，它与双螺旋模型非常相似。A－DNA与RNA分子中的双螺旋区以及转录时形成的DNA－RNA杂交分子构象接近。Z－DNA以核苷酸二聚体为单元左向缠绕，其主链呈锯齿形，故名。

Equilibrium equations of a binary mixture for molecular distillation were derived on the basis of heat and mass transfer in liquid films. Simulation on separation of tocopherol from rapeseed oil deodorizer distillate was carried out.

通过对分子蒸馏液膜表面流体流动和传质、传热分析，建立了二维分子蒸馏模型的传质和传热方程，并对菜籽油脱臭馏出物中维生素E的分离进行模拟。

It is widely used in molecular diagnostics,molecular biology research and animal and plant quarantine,etc.
