The total seed storage in topsoil (0-10 cm) was 83499-109141 indm^(-2) for natural wetlands and 9140-47452 indm^(-2) for reclaimed paddy fields. In natural wetlands, the seeds were of 16-30 grass plant species, being dominant with Polygonaceae and Cyperaceae or Cyperaceae and Gramineae; while in reclaimed paddy fields, the seeds were of 7-16 grass plant species, with the dominant of Gramineae. The seed storage and species numbers were greater in Shengjin Lake than in Shibasuo Lake. Higher seed bank storage and more species were observed in the paddy fields from Shibasuo wetland with 30 years of cultivation than from the Shengjin Lake wetland with over 50 years of cultivation.

Results: On dichotic listening task, the schizophrenic patients showed a left ear advantage during the non-forced condition, while the healthy subjects a right ear advantageLI}. An accuracy level of the schizophrenic patients' right ear, however, increased dramatically during the forced-right condition. When attending to the one ear,the schizophrenic patients showed an inability to ignore irrelevant stimuli from the other ear.

结果：两耳分听实验结果显示，非注意条件时，精神分裂症患者为左耳优势，而正常人则表现为右耳优势；精神分裂症患者在注意左耳或右耳时的成绩虽有明显提高，但对另一侧耳信息的抑制能力与正常人相比明显减弱。

Strabismus diorthosis under microscope has clear advantages compared with traditional strabismus diorthosis. The muscle, blood tube and the move of needle in sclera as well as the depth can be seen clearly during the operation which make the operation easy to control, so we can properly and correctly perform the operation, shorten the operation time and avoid complications like blooding, penetrate sclera which often occur during the traditional operation. The strabismus diorthosis under microscope using general micro equipments can also separate structure correctly with fewer operation steps, light reaction after operation, sooner recovery after operation, which is suit to patient who needs strabismus diorthosis.
