Cooperation: the Main Fountainhead of Divisible Efficiency in Modern Libraries - HaiChao, Su
Cooperation has been the main fountainhead of divisible efficiency in modern libraries，and it also has caused the integration of the two forms of library division including internal division and social division ，so correspondingly some hot issues on modern libraries can be integrated basing on the cooperation.

厦门大学图书馆数字化建设回顾与展望 - 黄国凡; 萧德宏
Since year 2000, we have provided solid ground for further digitalization development. Our long term goal is: focusing on network improvement, establish a large-scale, well-distributed and well-organized database and knowledge base system, provide available services for users to meet their academic information needs; materialize or partially materialize digitalized collection, automated operation, network information delivery, free information retrieval and saving, shared resources and well-connected structure. We will keep focusing on providing improved service quality and level to readers and users.

催化反应转化率与催化剂组分含量的关系式 - 李枫; 伊晓东; 林凌; 王跃敏; 方维平; 万惠霖
[中文文摘]针对三种不同物料连续流动催化反应系统:(1)MoVTeNbO/SiO_2用于丙烷选择氧化制丙烯醛反应;(2)KMoNi/SiO_2用于高硫合成气制甲硫醇反应;(3)MoNiP/Al_2O_3用于噻吩加氢脱硫反应。在各自的固定反应条件下,研究催化反应转化率与催化剂组分含量的关系,提出半经验表达式:x_A=1-exp[-G(w_i)],G(w_i)=。利用此式拟合上述3个催化反应系统的实验数据,平均相对偏差分别为1.97%,1.54%和1.42%,拟合精度较高,证明所提出的关系式是合理的,而且颇有普适性,可用于优化设计催化剂组分的含量。[英文文摘]Relationship of conversion to catalyst contents was studied for three different material catalytic reaction systems with continuous -flow of reactants as follows:(1) MoVTeNbO/SiO_2 catalysts for selective oxidation of propane to acrolein;(2) KMoNi/SiO_2 catalysts for methanethiol synthesis from high H_2S-containning synthesis gas;(3) MoNiP/Al_2O_3 catalysts for thiophene hydrodesulfurization. A semiempirical expression of relationship of conversion to catalyst contents was put forward and used to correlate the experimental data of the above reactions.Average relative deviation(ARD) are 1.97%,1.54%and 1.42% respectively. The high fitting precision indicates that the expression proposed is reasonable,widely applicable and can be used for optimizing component contents of catalysts.
