所有测试材料，无论表面吸附了多少电荷，都有这样的区域。
All materials they tested, no matter what overall charge they had picked up, showed this Mosaic pattern.
得到的吸附等温线分为三个不同区域：低压区等温线对压力轴呈凹形，高压区呈凸形，中间部分近似为直线。
The isotherm was devided into three different sections, at low pressure it is concave, at high pressure it is convex and the middle section it is nearly linear.
双切割区域可供交替工作，真空吸附系统可让材料紧贴切割台面。
The double-cutting area can work alternatively and the vacuum sucking system can make materials cling closely to the cutting interface.
