摘要
上海浦东国际机场建设占用了部分的滩涂，此部分滩涂是鸟类栖息延徙的活动区域之一。本文研究和比较了长江口浦东东滩和相邻九段沙的生态环境特点，评述了九段沙作为鸟类栖息迁徙重要“驿站”可能性的重要依据，并提出了相应的建议。
Two chiral liquid crystals of one series:(d)3M2CPNOB and (d)3M2CPHpOB were synthesized The phase transition temperature, the liquid crystal states, the hysteresis loop and the spontaneous polarization of (d)3M2CPNOB were determined It was proved that (d) 3M2CPNOB is ferroeletric liquid crystal with large spontaneous polarization
