Finally, the feasibility and applicability of the designed system was verified by practical particleboard hot-pressing experiment. The development of the Automatic measurement system for monitoring the internal-mat environment was based on LabVIEW program which is a powerful virtual instrument design workbench. Developed system in this paper can provide a friendly interface, an animated process-monitoring window including a real-time data acquisition of 2 pressure signal channels and 4 temperature signal channels, as well as the asynchronous serial communication between measuring computer and the data acquisition. Practical application testing and data analysis showed that this measuring system was useful and easy to operate by providing accurate and reliable data.

In the experiments, soil was tilled by rotary tiller at the depth of 10 cm, and compacted by holder/ walking tractor, wheel tractor and crawler tractor in one pass (T1), two passes (T2) and four passes (T3), while no compaction (T4) was applied as control.

试验中,先用旋耕机对田块进行旋耕,耕深10 cm,然后使用手扶式、轮式、履带式拖拉机在旋耕后的田块中通过1次(T1)、2次(T2)、4次(T3)以对土壤进行压实处理,对照组(T4)不作任何压实处理。

The results show that the decalescence of catalyst bed affects the process of hydrogen peroxide catalytic decomposition greatly. If the catalyst bed is preheated or made up of materials with low thermal conductivity, that influence can be depressed. At the same time, the response characteristic of catalyst bed and the efficiency of catalytic decomposition can be improved. The low frequency pressure instability of catalyst bed occurs because of the coupling of catalytic decomposition and supplying. The decomposition plane pushes all the way through the catalyst bed during pressure oscillations, causing unreacted liquid hydrogen peroxide to be exhausted from the bed and leading to the appearance of liquid hydrogen peroxide channeling. Consequently, how to prevent or at least limit this channeling is the key to eliminate the pressure instability of catalyst bed. It was found that adding clapboard to the catalyst bed can depress the pressure instability efficiently.

结果表明催化剂床及催化剂的吸热对过氧化氢分解过程影响很大,对催化剂床进行预热或采用热导率低的材料制造催化剂床等措施,可以降低催化剂床壁面吸热对催化分解过程的影响,提高催化剂床的响应特性和催化分解效率;催化剂床的低频不稳定是催化分解过程与供应系统耦合产生的,催化剂床气体界面的波动过程中,液体过氧化氢穿透催化剂床形成过氧化氢液体通道,过氧化氢液体通道的产生和扩大是催化剂床不稳定的主要原因,也是消除催化剂床不稳定的关键,试验中在催化剂床内加入分流板成功地抑制了催化剂床的低频不稳定。
