Raman spectra of a complex perovskite system(Pb_(1-x)Ba_(x))(Yb_(0.5)Ta_(0.5))O_(3),x=0.0;0.1 and 0.2 have been studied at low temperature in the range of 10–250 *** fascination of the system is that it undergoes a crossover from a highly ordered antiferroelectric(x=0.0)to ferroelectric(x=0.1)to disordered relaxor ferroelectric(x=0.2).The nature of splitting that prevails in F_(2g)(≈60 cm^(-1)),F_(1g)(≈538 cm^(-1))modes and their gradual merging and disappearance with x indicates an orthorhombic symmetry for x=0.0 and a pseudo-cubic structure for x=*** mode at 420 cm^(-1) suggests the existence of rhombohedral distortion in all the *** soft mode behavior of the F2g modes has been analyzed by fitting the data with the power law ω_(s)=A(T_(C)-T)^(β).

应用分子建模的方法可以模拟植物鞣剂对蛋白质的鞣制作用，识别相互作用位点，计算配位化合物的结合能，有助于理解胶原多肽与没食子酸之间的相互作用。计算不同几何结构的结合能范围为6—13kal／mol。研究发现，一些配合物之间显示出氢键，同时在没食子酸稳定蛋白质方面，静电作用占主导性，n—OH在维持多肽稳定性方面也起着一定的作用。600ps的分子动力学模拟（MD）说明，胶原多肽和没食子酸之间可能存在氢键。
