铣床

The hardware system of this machine is as follow: taken AC-servo-motor as power, taken ball screw as driving equipment, taken position transducer as feedback source gainer. The CPU of UP-PC is used of embedding chip, PXA-255 ofInter, and its system board is directly used of Intel's Sitsang board. On the other hand, the CPU of DOWN-PC is chosen of PMAC-104,which is the product of Motorola.

本铣床系统硬件构成如下：动力源选用交流伺服电机，传动装置采用丝杠，反馈量由位置传感器获得，上位机的处理器为嵌入式芯片Intel公司SXcale架构的PXA-255，上位机的系统板直接选用Intel公司的Sitsang板，下位机选用Motorola公司的运动控制器PMAC-104。

对82CNC数控铣床PC控制主机的升级改造涉及硬件系统和软件系统两个方面：在软件方面，采用硬盘克隆的方式并注意掌握好克隆过程中的关键技术细节，根据升级后所选用的功能组件和运行的硬件平台的不同来合理地裁减和配置相关的内核、驱动、BIOS设置，不仅可达到&事半功倍&的效果，还能彻底摆脱外方在技术上的封锁和限制，构建真正适用于企业环境的MMI操作界面，并拥有灵活的组网方式和自主的维护方法。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
