The coking and deactivation process of benzene and ethylene alkylation reaction over AB-97 zeolite has been studied systematically. The results of acceleration deactivation reaction indicate that deactivation process go through three phases, high level activity stability period, activity decline period and low level activity stability period. The mechanism of this phenomenon was analyzed by the way of the experiment research of pore structure and acid quality of coked zeolite. It is concluded that reducing the strong acid active centers and crystal outer-surface active centers are benefit to improve the activity stability of zeolite.

在AB-97型分子筛催化剂上对苯/乙烯烷基化制乙苯反应体系的结焦失活历程系统实验研究，催速失活实验结果表明失活历程经历高水平活性稳定期，活性衰退期和低水平活性稳定期三个阶段，并通过对失活催化剂的孔结构及酸性质的实验研究，对这一现象进行了机理分析，认为催化剂改性研究中采用降低强酸活性位和晶粒表面活性位这两种手段都有利于改善催化剂的活性稳定性。

Once more than one monolayer Pd is deposited on it and annealing to 700K~1000K, the structure of surface will transfer from planar (111) to faceting{112}, and pyramids with different size are formed on the surface.

所谓的皱化现象是由於bcc(111)本身就是较为不稳定的面，超过一层钯在钨(111)经过退火至700K~1100K，会露出能量较低的{112}面而形成遍布不同大小的金字塔的表面。

Uses the automated control not only on the galvanization production line to be possible to raise the product manufacturing efficiency and to reduce worker's labor intensity, and has the very good economic efficiency and the social efficiency, galvanizes on the production line to be possible to realize the automated control using PLC, PLC has the reliability to be high, the compatibility is broad, has the correspondence function, the structure modulation characteristic, therefore how to use good PLC to become the galvanization production line automation control key, auxiliary to galvanized the automatic production line driving with PLC by the frequency changer to carry on the automatic control, had the structure to be simple, the programming was convenient, the operation was flexible, the use safe, worked stable, the perform reliably and the antijamming ability strong characteristic, was one kind of very effective automatic controlThe way, is galvanizes the production to realize, the low cost, the high grade automated production development direction highly effective.

在电镀生产线上采用自动化控制不但可以提高产品生产效率和减轻工人的劳动强度，而且有着非常好的经济效益和社会效益，电镀生产线上运用PLC则可以实现自动化控制，PLC具有可靠性高，适应性广，具有通信功能，结构模块化的特点，因此如何使用好PLC成了电镀生产线自动化控制的关键，用PLC辅以变频器对电镀自动生产线行车进行自动控制，具有结构简单、编程方便、操作灵活、使用安全、工作稳定、性能可靠和抗干扰能力强的特点，是一种很有效的自动控制方式，是电镀生产实现高效、低成本、高质量自动化生产的发展方向。

A novel double hairpin molecular beacon that has more stable structure than traditional molecular beacon has been designed. Its hairpin structure will not fully open when it hybridizes to cDNA but the hybrid can be cut by restriction endonucleases, which leads to destroy of its structure and restore the fluorescence.
