运行持续时间

The tracked shot-blast machine is with simple operation. Put the work-pieces into tracked rubber roller and close the shot-blast chamber door. Then setup shot-blast time and push the RUN button. Now, the shot-blast cleaning is beginning. The track circumrotates in the forward direction. The work-pieces can be equably and completely cleaned with equal emission of high-speed shots from the impeller of shot-blaster.

履带抛丸机操作简单，将工件放入橡胶履带滚筒中，关闭抛丸室门，设定抛丸时间，操作人员按下&运行&按钮，抛丸清理开始，履带正向旋转，使工件持续收到抛丸器叶轮中高速抛出的弹丸均匀抛射，工件可完全、均匀地得到清理。

Based on those analyses and conformed international and national economic condition in china and some intrinsic defects of target zone regime, author transform target zone exchange rate regime by dividing two layers and bring forward a new exchange rate regime: double-layer-monitor exchange rate regime, the new model have possessed two merits, one is that the new model make "hollymoon effect" of target zone recurrence,and the merit can alleviate the fluctuation of exchange market;another merit is that the new model is a self-regulation system, that is say, the model can avoid long-term misalignment of exchange rate, those merit have major significance for china economy sustainable development and Chinese financial system more perfection, in paper we also present some fiscal policy and money policy served as a foil to double-layer-monitor exchange rate regime in order to make it work well, at last, we conclude that the new model will be the prior selection of RMB exchange rate regime reform for a long time form now on, and it also can serve as the bridge of RMB exchange rate regime steering to one of bipolar—free float.

在这些分析的基础上，并考虑到当前中国所面临的国际国内经济环境，针对汇率目标区的一些固有缺陷，笔者又对汇率目标区模型进行了分层改造，提出了一个新的汇率机制模型：汇率目标区双层监控模型，该模型有两个主要优势，一是可以使&蜜月效应&得以重现，从而避免外汇市场的过度波动；二是该模型是一个自稳定系统，能够进行自我调整，使实际汇率同长期均衡汇率保持一致，从而避免实际汇率的长期错位。这些优点对于我国经济的可持续发展，对于我国金融的更加完善，有着十分重要的意义。为使汇率目标区双层监控模型良好运行，论文还就相应配套的财政政策、货币政策措施作了探讨。最后得出结论，按照汇率制度&并存继起&假说，今后很长一段时间内，汇率目标区双层监控模型都将是人民币汇率制度的合意选择，另外，它也可作为人民币汇率制度向独立浮动制过渡的桥梁。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
