简述农作物秸秆工业品加工技术。

答案

参考答案:

农作物秸秆工业品加工技术主要以玉米秸、麦秸、棉花秆等各种秸秆为原材料,综合物理、化学、电气、机械、液压等加工技术原理,利用高压模压机械设备,经辗磨处理后的秸秆纤维与树脂混合物在金属模具中加压成型,制成各种高质量的低密度、中密度和高密度的纤维板材制品,再在其表面加压和化学处理,可用于制作装饰板材和一次成型家具。秸秆板材制品具有强度髙、耐腐蚀、防火阻燃、不变形、不开裂、强度高、美观大方及价格低廉等特点。秸秆板材的开发,对于缓解木材供应数量不足和供求趋紧的矛盾、节约森林资源、发展人造板产业具有十分重要的意义。

     "Do you like my dress?" she asked a stranger. "My mum made it just for me," she said with tears in

her eyes.

     "Well, I think it's very pretty, so tell me, little girl, why are you crying?"

     The little girl answered in a low voice, "After mum made me this dress, she went away. My dad says

that she's up in heaven (天堂) now with Grandfather."

      Finally the woman realized why she was crying. She felt very sorry for the little girl and gently held the

child in her arms.

    Then suddenly the little girl did something a bit strange. She stopped crying, walked back from the woman

and began to sing. She sang softly. It was the sweetest sound the woman had ever heard, almost like the song

of a very small bird.

    After the child stopped singing, she said to the lady, "My mum often sang that song to me before she went

away, and she asked me to sing it whenever I started crying and it would make me stop."

     "See," she said loudly, "it did, and now my eyes are dry!"

     Just before the lady wanted to go, the girl showed her a spot (印迹) on her dress, and said, "Right here is

where my mum kissed (吻) my dress, and here," pointing to another spot, "and here is another kiss, and here,

and here. Mum said that she put all those kisses on my dress so that I would forget my sadness."

     Then the lady realized that she wasn't just looking at a dress, no, she was looking at a mother. The mother

knew that she was going away and would not be there to kiss away her daughter's hurts any longer.

     So the mother gave all her love to her beautiful daughter and put it into this dress. Now her child was

wearing it so proudly.

     The lady no longer saw a little girl wearing a simple dress. She saw a child wrapped (包) in her mother's

love.
