To meet requirement of production and quicken rolling speed, No.2 heating furnace was put into operation in 2002 and No.3 in 2007. All automatic control was adopted, displacement of walking beam was detected by displacement transducer, and acceleration and deceleration control of walking beam was carried out through proportional valve and by use of slope technique in program of GE 90-70 PLC, thus, travelling speed of walking beam can be controlled and lift and release of slab can be operated lightly.

在双频激光干涉测量系统中，Wollaston棱镜是不可缺少的重要光学元件，它可将双频激光按偏振方向分为测量光和参考光，从而实现高精度测量；但是，如果Wollaston棱镜的安装方位相对入射光线方向以及与聚焦透镜距离不同时，测量结果将会不同。

Finally, from the view point of recording high-fidelity data page, we optimized the storage system by using beam shaper in signal beam, and redesigning geometry to increase the uniformity of reference beam. In the final demonstration experiment, we encode 10KB Flash to four data pages, each including 512×512 bits. The data pages are 1:2 pixels matched. These four data pages were stored in a single point in a photopolymer media of Aprilis Corporation by using angle multiplexing method, and successfully retrieved.

根据我们设计的串行二进制数字数据与数据页之间的编解码方法，将一段10KB大小的Flash视频编码为4幅512×512幅面，1：2匹配的数据页，并成功的在美国Aprilis公司光致聚合物材料中完成了这4幅数据页的单点角度复用存储，再现数据页经过偏移补偿算法和PMSF算法处理后的平均原始误码率为2.4×10-4，这样低的误码率完全满足后期软解码的需要，并使得解码后的数据可以满足用户误码率的要求。

The electron beam current measured by the beam current monitor (BCT3) is almost in direct proportion to the induced voltage of the fundamental harmonic. When the parameters of the pre-buncher and buncher are adjusted greatly while the beam current being unchanged, the fifth harmonic signal has a great change, but the fundamental signal changes gently. The test results are all in good agreement with the theoretic analysis.
