The Character Voltage in Supertwisted Nematic Liquid Crystal Display with Weak Anchoring

弱锚定条件下超扭曲向列相液晶显示的特征电压

All Twisted nematic ( TN) and supertwisted nematic ( STN) LCD, including both active and passive matrix, suffer from poor performance at wide viewing angles due to the electro optical properties of the liquid crystal materials.

扭曲向列型（TN）和超扭曲向列型（STN）LCD，包括有源和无源矩阵，都有一个共同的缺点，即视角狭窄；这是液晶材料的电光特性所造成的。

Meanwhile, explore the plasmid losing rate and the proportion of supertwisted plasmid DNA during fermentation. Results The copy number of plasmids of recombinant strains DH5 α/ pS2. S and DH5 α/ pFP were stable during subculture for 30 passages.

结果工程菌DH5α/pS2.S和DH5α/pFP在连续传代30次后，质粒拷贝数保持稳定。
