Look from breed, breed is little and class is low, the horniness beaverboard with slow-moving market still fails to exit historical arena completely; And market demand is bigger high grade plywood, medium density beaverboard and crop of much performance particieboard are opposite people little; All sorts of facing machine the proportion of the product to still be not worth knife ％; The product that undertakes sex of characteristic, function is machined is fewer.

从品种上看，品种少且档次低，市场滞销的硬质纤维板仍未能完全退出历史舞台；而市场需求量较大的优质胶合板、中密度纤维板和多性能刨花板产量相对们少；各种饰面加工产品的比重尚不足刀％；进行非凡性、功能性加工的产品则更少。

The system inherits the advantages of the combustion control systems of single and double cross amplitude limits, having overcome the disadvantages. It not only guarantees the system response performance of change in load, but also takes into account the economic performance of the system.

该系统继承了单交叉限幅燃烧控制系统和双交叉限幅燃烧控制系统的优点，克服了不足，在保证系统变负荷响应性能的同时，还兼顾了系统的经济性能。

As it is only stiffer and having less overhang, both handling and ride are superior.

不是因为它有点僵硬和有些转向不足的话，他们两者的操控性能和驾驶性能都是一流的。

The First Law of thermodynamics and exergy analysis method were used to construct factors such as coefficient of performance , exergy efficiency and exergy index according to the AHT combined Carnot cycle model established. Aimed at the insufficient of the classical thermodynamics analysis method, the optimization relationships between the specific heating load and operating parameters, and between SHL and COP, was reasoned out using the Finite Time Thermodynamics method according to the characteristic of investment and capacity of AHT, and endo-reversible combined Carnot cycle model. Hence, the rationality of the energy utilization and the economic index, which related to the total heat transfer area, were both taken into account.
