METHODS: The 15 hybrid dogs were randomly divided into 2 groups. In the experimental group (n=9), a hole was drilled at the slope beneath the tibial plateau to reach the medullary cavity. The cavity was enlarged by an appropriate drill to confirm the size of the cavity. The absorbable polyamide intramedullary rods were inserted from the hole in tibial superior extremity, and the fracture was anatomically reduced with the rod passing through the fracture. Two locking nails, which were cylinder polyamide rods, were respectively located 2 cm from the cutting site, in the distal and proximal ends. Auxiliary plaster external fixation was performed for 4 weeks. In the control group (n=6), quincunx intramedullary nails of the same diameter with 4 pre-drilled holes were accordingly inserted into the cutting segment, and 2 screws were locked in the distal and proximal ends, respectively.

15只杂种犬随机分为2组，实验组(n=9)：在距离胫骨平台下斜坡处钻孔入髓腔，用合适钻头扩大髓腔，确认髓腔大小，从胫骨上端开孔插入聚酰胺钉，解剖复位骨折端并使该钉通过骨折处，在距离截骨处2 cm处的远近端分别锁上2枚锁钉，锁钉为圆柱形聚酰胺棒，辅助石膏外固定4周；对照组(n=6)：同样插入相应直径的、已预钻4孔的梅花形髓内钉截段，在骨折端的近端及远端分别锁2枚螺钉，辅助石膏外固定4周。

The invention relates to a method for adopting a compound reducing agent to reduce and decompose phosphogypsum; the method comprises the following steps of: using high-sulphur coal and coal gangue to prepare the compound reducing agent; utilizing tail gas to dry the phosphogypsum and the compound reducing agent which are ground and mixed evenly and then transferred into a reducing and decomposing furnace; carrying out reduction and decomposition till the reaction is completed.

要約 本发明涉及一种采用复合还原剂还原分解磷石膏的方法，该方法将高硫煤和煤矸石配成复合还原剂，再将磷石膏、复合还原剂利用尾气烘干、磨细后混匀送入还原分解炉，进行还原分解，直至反应完全。
