The molecular weight of broad bean vicilin and legumin measured by gel filtration chromatography were 135000 and 351000, DSC showed that their denature temperatures were 72℃ and 87℃ respectively. The legumin had a lowest solubility at pH 4. 5-5. 0 whereas the vicilin at pH5. 5. Vicilin and legumin were all possessed low levels of α-helical and high β-sheet secondary structure fractions. The total content of α-helical,β-sheet and β-turn fraction of vicilin and legumin reached to 90% and 78% separately showed that they had a high ordered structure in solution.

对两种组分的凝胶层析表明7S和11S的相对分子质量分别为135000和351000；DSC分析显示其热变性温度分别为72℃和87℃；溶解度分析表明：11S球蛋白在pH4.5-5.0之间，7S球蛋白在pH5.5时具有最低的溶解度；圆二色性分析结果显示7S和11S球蛋白的β-折叠结构含量分别高达40.5％和38.1％，证明二者都属于β-折叠型蛋白质，二者的α-螺旋、β-折叠和β-转角结构的含量总和分别达到了90％和78％，从而说明它们在溶液中的结构是高度有序的。

The microstructure of MDF and MDF tested were studied. The results showed that the fibers in MDF are arranged randomly. Some of them arranged separately, most of them arranged in bundles. There are many blind holes between the fiber cells in MDF. The damage of MDF's compressive creep is the result of new cranny occuring, spreading and the combination of old cranny. In the repressing process, besides the pressure, heat is also the main factor on the damage of MDF, which can accelerate the adhension layer to deteriorate and lead to the gule strength decreasing.

结果表明：MDF的纤维排列无规则，纤维排列形态除少量纤维呈单根状外，大量的纤维以纤维束的形态排列；纤维之间存在许多大小不等的孔洞，呈不贯通状；MDF蠕变损伤是不断萌生新的裂隙并扩展和合并原有裂隙的结果；MDF二次加工过程中，除了压力是破坏MDF结构的主要因素外，加热温度使MDF胶层老化，胶合强度下降，也是破坏MDF结构的主要因素；MDF的破坏形态除了有纤维拉断外，还有纤维拔出和胶粘剂脱落。

In the situation of varied water quality of influent, membrane permeate COD was all less than 20mg/L, NH〓-N was less than 1mg/L and turbidity was less than 1 NTU.
