For this objection, we propose a kind of optimal interpolator in the senes of the minimizing mean square error, which using the image nonseparable autocorrelation function model and characteristic of circular quincunx interpolator's coefficient distribution. The experiments testified that the interpolating characteristic of APIDCSF is similar to the optimal interpolator. A quasi-vanishing moment curve is proposed here.

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.
