Based the above research, we chosen 48 cephalometric radiographs of skeletal classⅢocclusion (18-39 years old, ANB4°) and measured with computer assistant Delaire cephalometric analysis. The data were deal with ANOVA analysis through SAS9.0 statistical software. The research divided the cranio-maxillo-facial hard tissue structure feature of skeletal classⅢinto four classifications through Delaire cephalometric analysis including hypo-divergent, hyper-divergent, maxilla normal and glenoid fossa retrocession, nine parameters of four groups have significantly variability through ANOVA analysis(P.05),for example, anterior cranial base angle, sphenoidal angle, percentage of craniospinal area to cranial depth ,percentage of craniofacial area to cranial depth and so on.

Analytic branch amount and branch angle are right produce can influence discovery: Mi Qian is planted increase of number of branch of? of You of that a pavilion or house on a terrace of joyous ǖ of Сざ sew, produce can reduce somewhat, think branch well should not seek overmuch branch amount, with 2~3 branch is advisable; branch angle increases, the yield of much branch well also can increase, but addition extent decrescent.

分析分支数目和分支角度对产能的影响发现：在总分支长度一定的情况下，分支数目增多，产能略有降低，认为分支井不应追求过多的分支数目，以2~3个分支为宜；分支角度增大，多分支井的产能也增大，但增加的幅度变小。

The horizontal and vertical first derivatives of magnetic anomalies of an infinite cylinder are calculated by the cosine transform method, in which the maximum errors are -0.28 nT/m and 0.47nT/m, respectively and the percent errors are generally within -3.57%~3.27% and -1.94%~1.88%, respectively except several data of the boundary and part are bigger because of remains of Gibbus effect. The calculating curve and theoretical curve are approximately coincident, and there is no influence by effective magnetic dip angle in computing. But the errors with the Fourier transform method are -10.62nT/m and 14.42nT/m, there is large departure between the calculating curve and theoretical curve and evident influence by effective magnetic dip angle in computing.
