The detailed analyzed and simulating of focusing error signal of optical pickup based on oblique parallel plate glass was carried out. The new scheme for generating focusing error signal based double reflection plane BSP was proposed. As a result, the structure of optical pickup was simplified, and the cost of optical pickup was reduced. The scheme was not reported in domestic and international literature formerly. Now, author obtained the patent on this scheme.

However, in some situations, models are hard to satisfy these assumptions at the same time. We meet a number of random errors with serial correlation and heteroscedasticity in practical problems. The rationality of these assumptions for random errors is doubtable. Therefore, it is necessary to test for correlation and heteroscedasticity in regression, which is an important step of dealing with regression problems and plays an important role in theory and practice.

但实际问题中，回归模型很难同时满足Gauss-Markov的三个假设，人们在实际问题中发现许多随机误差出现序列相关和方差不同的现象，因此对回归模型的随机误差的独立性和方差齐性的假设产生了质疑，从而展开了回归模型的相关性和异方差检验的研究，它是处理回归问题的重要步骤，在理论和应用上都有十分重要的意义。
