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.

同时由于有机组分甲基和亚甲基的引入，结构均匀致密，并具有一定的疏水性；电化学测试结果表明BMBSE膜的极化阻抗比不锈钢大4个数量级，自腐蚀电流密度也下降低了4个数量级左右，具有良好的耐腐蚀性能；成膜的影响因素优化结果表明BMBSE、EtOH、D.I.water摩尔比为1∶4∶3，热处理温度为200℃时，更有利于制备结构均匀、致密、耐腐蚀性能好的薄膜；静态浸泡腐蚀实验结果说明，在180℃、55%的高温溴化锂溶液中BMBSE膜能起到良好的腐蚀防护作用。

Furthermore, in this experiment, the chopped sugarcane should be stored at the tempreture of 10 C belove zero and the humidity level of 90%, besides, it should be packed with B preservative film, for which is good at keeping water and storing

The hydrophobicity and topology of the surface of the lotus leaf are a consequence of its special surface structure (branchlike nanostructures on top of micropapillae), which gives rise to a super-hydrophobic surface with a large CA and a small sliding angle.

24疏水性以及对荷叶表面的拓扑结构是其特殊的表面结构的结果（branchlike 纳米结构的micropapillae顶部），这就会引起超疏水表面有大量CA和一个小滑动角。

The achievement of this project can be briefly summed up as following:(1)the carbon contributing to karst processes mainly comes from ecological system itself under the condition of existence of vegetation and soil covers;(2)results indicates that the depositing processes of rainfall to CO2 is an important "sink" to global carbon cycle;(3)owing to the differences of vegetation and surface covering, the adjusting effect of ecosystem to environmental humidity, temperature and CO2 concentration near surface air which indicates different benefit of preventing water and soil from lose is marked;(4)the preponderant species of vegetation in the karst ecosystems which have different kinds of carbonate rocks are obviously variant, and this situation results to the clearly differences of the micro － habitat , structure of surface cover and water holding capacity;(5) the relevant study showed that the carpophagous animals and birds make a important role in the spreading of vegetation seeds. The designed experience for the study of seed reservoir was not able to obtain a satisfactory result.

主要研究成果包括：通过对表层系统碳库的研究，认为在有土壤和植被覆盖时，岩溶作用过程中的碳主要来自生态系统本身而不是母岩；降雨对大气碳具有重要&沉淀&作用，是碳的一个重要汇；不同植被类型表层岩溶系统对系统水份、空气湿度、气温、土温和近地表 CO2浓度等具有明显调节作用，具有不同的水土保持效益；不同母岩的岩溶生态系统的植被优势种、属差异明显，由此形成的小生境、地被物及其持水性差异巨大；对典型岩溶表层系统种子库的试验研究没有取得满意结果，但食果动物、鸟类对种子传播起到一定作用。
