乙酸乙酯分离竹子中木质素制浆造纸研究

用乙酸乙酯浸提竹子制取纸浆，并用造纸行业相关国家标准对纸浆进行了分析。探讨了乙酸乙酯浓度、反应温度、反应时间、原料与溶剂的固液比对纸浆质量的影响。实验结果表明：当乙酸乙酯浓度为60％、反应温度为180℃、反应时间2h、原料-溶剂比为1：6时，制得的纸浆中残余木素含量相对较低、纸浆得率较高。     

也论中西精神--与张秀成先生商榷

本文认为，中学和西学各有优劣，应互相吸取，但在总体上是西学优于中学。首先，在思维方式上，西学的分析思维，使西方社会分工较细，促进了社会化大生产的产生；也使西学学科门类众多；西学在方法上崇尚专精深，对任何问题都穷追不舍，非要证明或证伪，促进了科学的进步。中学的综合思维则使中国社会分工不细，学科门类不多，在研究方法上则不究细节。其次在义利关系上，西方私有神圣，最后却私也有了公也有了；中国公有神圣，改革开放前却公也没有私也没有。再次，在男女关系上，西学以个体为本，正是为了自身的尊严不受侵犯，才不得侵犯他人的尊严，这就有了平等精神。相反，古代中国的根本大法是三纲五常，夫为妻纲、男尊女卑，被论述为符合阳主阴辅的天道法则，追求男女平等，就是违反天道，就会被天诛地灭，中国没有男女平等。

The behavior of the homozygous and heterozygous sub-types of rats which are genetically-selected for diabetes insipidus: A comparison with Long Evans and Wistar stocks

Several aspects of spontaneous and conditioned behavior (food and water intake, locomotion and emotionality, passive and active avoidance acquisition and retention) of standard (albino and pigmented) rats, and rats heterozygous (HEDI) and homozygous (HODI) for diabetes insipidus, are reviewed. As would be expected, HODI rats have been repeatedly found to consume far more fluid than either HEDI or control rats. Pigmented rats appear to be more active than albinos. HODI rats exhibit less marked emotional responses than do control rats, among which the pigmented ones exhibit the highest emotionality. Light aversion is more evident in albino than in pigmented rats. No differences are found among HEDI, HODI and normal Long Evans rats. It is quite difficult to provide a clear-cut statement concerning inter-strain differences in passive avoidance behavior, possibly because of the variety of techniques employed. In any case, HODI rats do not perform worse than normal controls do. In one-way active avoidance paradigms, pigmented rats perform better than albinos, and the performance of HODI rats does not differ from that of controls. In two-way avoidance paradigms, albinos appear to outperform pigmented rats. Once again, there are no obvious differences between HODI and control animals.In addition to indicating that HODI rats may actually be less emotional than the other groups of rats reviewed here, the studies described once again fail to confirm the previously alleged functions of vasopressin in memory consolidation.
