Based on this thought, in this thesis, the alternation theorem is first extended to the Chebyshev approximation problems with inequality constraints, and then two algorithms are devised for designing linear phase FIR filters with inequality constraints in Chebyshev sense according to the extended theorem.

L.J.Karam和McClellan在文献[20]中把交错点组定理扩展到复数域，并提出了求解复系数FIR滤波器的复Remez算法，但由于此扩展定理只是一个充分条件，所以此算法不能保证得到最优解。在文献[23]中，他们对复Remez算法进行了完善，使其收敛到最优解。

At the same time, with the development of the people's recognization to the principle of the social affairs and alternation of the governmental social management, the incompulsory methods will more and more function comparable to the compulsory methods.

The most suitable range of temperature is 25~30℃ and lethal temperature is 56℃ for hypha growth, the most suitable temperature is 25℃ for produce more conidiospore and lethal temperature is 56℃ for conidiospore. Within the pH range of 3~11 the hypha could grow and produce conidiospore. The optimum pH is 5~7 for hypha growth and 3, 9, 10 for produce more conidiospore. The range of glucose concentration is 2%~8% for hypha growth, the most suitable glucose concentration is 2% for hypha growth and produce more conidiospore. The effect of illumination on Bipolaris cynodontis was significance to the growth hypha and spore numbers. The whole light is advantage of hypha growth, but could not produce conidiospore. Alternation of light and darkness for 12 hours is advantage of hypha growth, as well as produce conidiospore.

菌丝最佳生长温度是25~30℃之间，在25℃时最利于产孢，菌丝生长和分生孢子的致死温度是56℃；该菌在pH 3~11范围内均能生长，产生分生孢子，菌丝生长的最适pH 5~7，产孢量最大的pH是3，9，10；糖浓度在2%~8%菌丝能生长，在糖浓度为2%时菌丝生长最好，产孢量最高；光照对病原菌的菌丝生长和产孢有明显影响，在全光照的条件下有利于菌丝的生长，但不会产孢，黑暗12h光照12h既利于菌丝生长又利于产孢，而全黑暗的条件下不利于菌丝生长和产孢。
