Giant in the core technology to set up in zhejiang Quzhou City, mainly through the investment or acquisition electronic chemical materials realize the endogenous development of industry and through the integration of domestic and foreign excellent electronic materials enterprises implement denotation expansion. In the establishment of giant core technology help the company to seize electronic chemical material industry development opportunities and gather the development resources, accelerate the process of product localization and industry overtaking corners, and achieve the transformation and upgrading of the enterprise and the sustainable development, realize sustainable return on investment. High compression ratio if choose low grades of gasoline engine, can make the cylinder temperature rises, the incomplete combustion of gasoline, strong vibration machine, so that the output power down, damage to the parts, fuel consumption and driving. If lower compression ratio engine with high grade oil, can appear "delay" phenomenon, namely the compression ratio is less than the highest point of spontaneous combustion, as will appear incomplete combustion phenomenon, the engine is no good. Famous British economist hicks and others argue that the above theory did not consider the factor of income, and therefore unable to determine the level of interest rates, in 1937, and puts forward the is-lm model on the basis of general equilibrium theory.
