采用XRD、XPS、BET吸附、脉冲中毒、TPD、IR等方法,探讨了硼改性后HZSM-5沸石分子筛孔结构和表面酸性的变化对甲苯和乙醇烷基化反应活性和选择性的影响。BHZSM-5沸石催化剂能在活性稍有降低的基础上使甲乙苯产率和对甲乙苯选择性大大提高。当烷基化剂乙醇含水量少于3.%时,也得到相近的结果。处理剂H_3.O_3.以B_2O_3.形式分布于沸石晶内外的,使其晶面间距,比孔容、比表面减小,而Γ_(p-ET)/Γ_(m-Et)增大。表明沸石孔道变窄,对甲乙苯相对更易扩散。同时,B_2O_3.调变了HZSM-5沸石的表面酸性。外表面酸中心为B_2O_3.覆盖,以致脉冲中毒实验中,4.甲基喹啉基本不起作用。TPD谱中表征强酸中心的高温峰消失。IR谱中表征B酸中心、L酸中心的特征吸收带强度变弱,即B、L酸中心数同时减少。不是所有酸中心都是活性中心,只有处于一定大小空间、具有适当强度的酸中心才能满足对烷基化反应活性和选择性的要求。此外,ESR谱表明,L酸中心参与了甲苯烷基化过程。

用新生大鼠的迷走神经结状神经节与心肌细胞进行联合培养，用扫描电镜观察了神经纤维或神经终末与心肌细胞之间的关系。在低倍下可见结状神经节组织块长出的神经纤维呈放射状向四周延伸，到达分散的心肌细胞表面；在扫描电镜高倍下所观察到的神经纤维或神经终末的形态不同，神经纤维粗细不一，在单个心肌细胞表面相互交织成网状。有的神经纤维在行程中粗细基本均匀一致．而有的神经纤维则在行程中出现膨体样结构。终止于心肌细胞表面的神经终末的形态也不相同，有的末端膨大终止于心肌细胞表面，有的末端膨大并呈扇形展开后紧贴于心肌细胞表面，这种膨大的神经末梢与心肌细胞之间的关系似比在体时更为密切。

In this paper, 2-(1, 3. 4.triazolylazo)-5-diethylamino phenol (TZAPN) and 2-(5-carboxy-1, 3. 4.triazolylazo)-5-diethylamino phenol (CTZAPN) were prepared, the protonation behaviour and the condition of spectrophotometric determination of cobalt with the reagents are reported. The results show that the new colour reagents react with cobalt to form a stable purple red complex (1:3.. However, the complex formed could be changed into another species of stable absorptivity by addition of mineral acid (1+1). The method is highly selective and sensitive and has been applied to the direct determination of cobalt in some alloys with satisfactory results.

本文采用Lugiato的绝热消除方法讨论多光子理论。得出无论是良腔、还是劣腔情况其结果不仅包含了以前用Gordon绝热消除方法所得的,而且还能直接计算已被绝热消去的变量的关联,特别是在劣腔情况用两种方法计算得的场算符涨落的关联稳态值是不同的。由于Lugiato方法是自洽的,所以更为合理,在附录中还给出了劣腔情况多光子原子压缩公式及透射光谱公式。
