| | According to the fundamental relations of projectionu for inclined holcs, the writers made a BASIC program for calculating projection lines (five at the same time), printing data sheet and drawing, synthetic projections.A new formula is given. It can be used to compute the true dip of a stratum and determine whether it is positive or negative. In addition,the regularity of the projection displacement is discussed. The program and the regularity are appropriated to both stratiform and stratoid deposits. | | 根据斜孔投影原理编制出一个BASIC程序,可同时计算五种投影、打印数据和绘制综合投影图件。文中推出的公式,可用已知的测斜数据(方位角、天顶角、岩心倾角、岩层走向)准确计算岩层真倾角并判定钻进的顺逆。探讨了投影位移规律。上述程序和规律,适用于各类层状或似层状矿床。 | | 文摘来源 | | According to the scheme in design of main drift chamber (MDC) on BESIII, the error matrix of five parameters are calculated with TRACKERR. The five parameters are ζ(the displacement in Z), s(the tangent of the dip angle, the dip angle is λ(=π/2-θ),ξ the displacement in the x-y plane perpendicular to the projection of the track direction vector onto that plane), φthe azimuth of the particle's direction), and K (the inverse of the radius of curvature). At the same time , the responding momentum resolution an... | | 根据BESIII主漂移室(MDC)的设计方案,利用TRACKERR程序对主漂移室的带电径迹的5个参数ζ(Z轴方向的位移)、s(dip角的正切)、ξ(带电径迹在XY平面的投影位移)、φ(方位角)、Κ(横向动量的倒数)进行误差计算,得到了相应的误差矩阵。给出主漂移室对动量为1GeV/c的带电粒子的动量分辨率和空间分辨率。 | | 文摘来源 | |   |
