The method is realized by that polyether ether ketone is added into concentrated sulfuric acid to carry out sulfonation reaction, thereby obtaining sulfonated polyether ether ketone, then the sulfonated polyether ether ketone is dissolved in organic solvent, N, N (1)-Carbonyldiimidazole is added to stir for one to three hours, coupling agent is mixed for stirring the reaction for 1.5 to 4 hours, then inorganic crosslinking agent is mixed to react under the temperature of 50 to 80 DEG C. Proton conductors are mixed to continue getting the mixed solution of the sulfonated polyether ether ketone or the inorganic crosslinking agent or proton conductors under the temperature. Finally the proton exchange membrane for a direct methanol fuel cell is obtained by that the mixed solution of the sulfonated polyether ether ketone or the inorganic crosslinking agent or proton conductors is/are processed through membrane forming, drying and exuviation.

According to the direct or indirect method of being influenced, Taoistic poems can be divided into two categories correspondingly. Those poems influenced directly by Taoism includes intercourse eulogy between poets and priests, and depressed Taoist landscape poems. Those poems influenced indirectly by Taoism includes poems imitating placid style and autarkic reclusion of Tao Yuanming, poems imitating unrestricted style and fairyism of Li Bai and Li He, and poems admiring Taoist inclusion and deity's immortality.

这些诗从影响方式可分为受道教直接影响的诗歌与受道教间接影响的诗歌，前一类型包括两种：一为诗人与道士之间的赞美式的酬唱赠答诗，二为带有沉重思绪的游宫观山水诗；后一类型包括三种，一为学陶渊明的冲淡诗风和躬耕隐居的诗歌，二为学李白、李贺的自由张扬与具有神仙思想的诗歌，三为羡慕道徒隐居和飞升成仙的慕道诗。
