The instantaneous current capacity may demonstrate through the nixietube, provides the craft data reference for the operator.8031If the system the setting value carries on again the current capacity actual value the comparison, calculates the control quantity after the PID adjustment operation vi, again transforms into the electric current output signal, after but controls the silicon-controlled rectifier after the enlargement the breakover angle, the realization adjusts the slippery difference electrical machinery magnetic clutch exciting current the function, thus the adjustment implementing agency slippery difference electrical machinery rotational speed, causes to transport on the leather belt the material current capacity to stabilize as far as possible nearby the setting value, and has the good static target and the dynamic performance.

瞬间流量可通过数码管显示出来，为操作人员提供工艺数据参考。8031系统再将流量实际值与其设定值进行比较，经PID调节运算后计算出控制量vi，再转换为电流输出信号，而后经放大去控制可控硅的导通角，实现调节滑差电机电磁离合器励磁电流的功能，从而调节执行机构滑差电机的转速，使输送皮带上的物料流量尽可能稳定在设定值附近，并具有良好的静态指标和动态性能。问题补充：希望大家不要给机器翻译的答案，我想要人工翻译的，谢谢大家了

1 When thickness of the short pitch or long neck flange straight side of Type B doesn't equal to the cylinder thickness connected with it: If cylinder thickness is not larger than 10mm, and thickness difference with short pitch or long neck straight side is larger than 3mm; If cylinder thickness is larger than 10mm, and thickness difference with short pitch or long neck straight side is larger than 30% of the cylinder thickness or 5mm, Type B flange should take the slope value 1: 3, and the long neck flange should be thinned according to Chart 1, or have pile welding on the end of butt welding seam to achieve transition.

6.5.1 乙型法兰的短节厚度或长颈法兰的直边厚度与其相联接的圆筒厚度不等时：若圆筒厚度不大于10mm，且与短节或长颈直边厚度差超过3mm；若圆筒厚度大于10mm，且与短节或长颈直边厚度差大于圆筒厚度的30%或超过5mm时，乙型平焊法兰应按斜率1：3，长颈对焊法兰按图1虚线削薄，或者在对接焊缝的筒体端部按图2堆焊过渡。

It is shown that in Jameson's algorithm is not an orthogonal stream-lines coordinate system, but a local stream-lines coordinate system instead. Nevetheless, because of the finite-difference discretization in Jameson's scheme is not carried out along the direction of s and n, but along the Cartesian coordinates, the analysis on all terms of the full potential equation in Cartesian coordinates reveals that his scheme does take a back-ward difference along the streamwise exactly at all points in the supersonic flow region.

表明其所采用的坐标系不是真正的正交流线坐标系，而是局部流线坐标系；同时由于Jameson方法并不对s，n进行差分离散，而是在原笛卡尔坐标系下作差分离散，对笛卡尔坐标系下的全位势方程中的各项的分析表明，Jameson方法恰好能做到在超音速点沿真正的流线方向作后差分。
