Meanwhile, the coated surface was hydrophobic with a contact angle of 107.2°since the introduction of methyl groups and methylene groups. Static immersing corrosion test, potentiodynamically polarization curve and electrochemical impedance spectroscopy were conducted to evaluate the film corrosion performances. The results of potentiodynamically polarization curve and EIS in 55wt% LiBr solutions at room temperature in atmospherical pressure indicated that the corrosion current density of BMBSE film coated surface was 4 orders of magnitude smaller than that of bare SUS304 steel, and the impedance was increased by a factor of 10000. Static immersing corrosion test presented that the BMBSE film can significantly increase the corrosion resistance in 55wt%LiBr solution at 180°C compared with stainless steels.

The whole curve appears near S shape curve which revealed that the compound eyes of green lacewinng have strong adapting ability to light stimuli.4 Relation of the dark-adapted time and ERG value indicates that time of day eyes turning to night eyes is not similar in different kind of species. The turn of compound eye from day eyes to night eyes need about 120min in Chrysopa sinica Tjedar,, but is not accord to in different unit the other two species.

以ERG值为指标，在—定时间内，暗适应时间长短影响草蛉复眼的ERG振幅的大小，不同种革蛉其ERG值达稳定所需时间是不—致的，中华草蛉一般都需要120m，ERG值才能达到稳定，而大草蛉、丽草蛉不同个体ERG值达到稳定的时间不完全一致，大草蛉ERG值一般需60-90m达稳定，个别在120m左右达稳定，丽草蛉ERG值一般在60m左右达到稳定。
