Using mordern physical chemistry techniques (such as XRD、 TG-DTA、 IR、 XPS and 〓Xe-NMR)、 chemical adsorption techniques (NH〓-TPD、 H〓-TPD、 TPO、 TPR etc.) and pulse flow microreaction of n-hexane、 methylcyclopentene and n-hexane containing 0.2ppm thiophene, we studied mainly the following three points:(1). the changes occured during the calcination pretreatment of Pt ammine complex supported on β and L zeolites;(2). the effect of structure and acidity-basicity of zeolite on the dispersion and electron state of Pt particles; and (3). the influence of second metal component on the reactivity of nhexane aromatization and sulphur-resistance of Pt/L zeolite catalyst. Several interesting and valuable results are obtained and summerized as follows

To stoop so low as to become foreign mercenaries, for a piece of paper that will not serve as a carte blanche to mainstream society (that remains a function of education, I think), is simply inferiority complex gone wild, and shows an appalling lack of breeding on the part of their families, and a sense of historically amorality that simply beggar belief.

迈克尔杰克逊把皮肤漂白了也做不成白人，一个人越是想进主流社会，越是永远达不到那个心理和文化境界。假设所谓主流社会的入场券不仅仅是钱。我现在只想去巴西，去完巴西去非洲，去完非洲去中东。我真的不在乎美国的主流社会，或任何国家的主流社会。
