在数千年的造纸发展史上,传统的湿部化学品的加入和混合一直是利用加后稀释水的方法通过静态在线混合器来完成的,由于湿部化学品的加入量很小,,其流量仅为 0.1~1升/秒甚至更小,而要将如此之小的流量加入到纸机流浆箱300 ~2000 升/秒的工艺系统浆料流体中,同时达到化学品与造纸纤维均匀接触,即使是消耗大量的清水和使用在线混合器也很难达到&完全&且&有效&地混合,于是就又产生了将化学品的加入点,提前到远离流浆箱的工艺位置,这样可以延长混合时间,但人们忽略了在过早加入化学品的同时也带来了化学品的流失、化学品在短循环系统循环产生有害副产物生成浆管悬挂、化学品水解失效等一系列弊病。

I used the homemade ECDL to measure the 2S-3D two photon transition spectrum of Helium , the advantages are that the expense of homemade ECDL is cheap and have good output power. At the same time, I used the electronic part can be got in the market to manufacture a pulse generator in the experiment, the pulse generator can control the output frequency, the pulse width, the relative phase and also can simultaneously control four sets of systems or instruments need the TTL pulse control. The advantage is that the cost of the pulse generator is cheap and the pulse generator is stable. To isolate the magnetic field I used the magnetic foil to helium cell. I also built a gas discharge system, the switch sequence of this system can be controlled by the pulse generator. Finally I built a detecting system can measure the helium energy state. It is cheap and can be combined with the comb laser system in my laboratory.
