判定中药膏滋收膏终点的实用方法研究

目的:比较不同判定膏滋收膏终点的控制方法,确定科学、便捷、实用的控制方法,以求指导运用于膏滋制剂的生产。方法:采用振荡型密度计法、比重瓶热测法、黏度法、水分法、温度对比法、折光率法分别测定不同品种膏滋在不同的相对密度下对应参数,对不同测量方法下对应测量结果的准确性、便捷性进行分析比较,筛选出简便、快速、准确的控制方法。结果:膏滋的相对密度与温度和水分含量有着密切关系,与传统相对密度测定方法相比较,振荡型密度计法和折光率法可以快速测定膏滋的相对密度,操作便捷、准确度高、重现性好。可有效控制膏滋收膏工艺,指导膏滋制剂生产。结论:结合实际生产情况,从经济、便捷、准确等方面综合考虑,相比振荡型密度计法,折光率法投入的经济成本更低,普通生产型企业更易购置,有利于大规模普及应用,最终确定折光率法更适宜用于判定中药膏滋收膏终点,有利于完善膏滋生产质量控制体系,准确地对膏滋收膏终点实现精准判断,为中药膏滋制剂生产提供参考。

Evaluating and Measuring Relational Capital by Defining Knowledge

As we are in the knowledge economy, the main purpose of this research is to define the value of relational capital by measuring it with an innovative model. To this end, this paper will explain the meaning of intellectual capital （human capital, structural capital, and relational capital） in the field of knowledge economy and what relational capital is and how we can measure its value. The research is qualitative in nature and was developed through the study of the international literature. The research presents some theoretical evidences that permit defining a method for the evaluation of relational capital. In this direction, the above method will need to have some integration in the future research. Moreover, this approach should consider some empirical evidences to establish the practical value of the method. In fact, the method presented encourages debate and a critical attitude towards the evaluations of relational capital and intellectual capital.

Experimental Study on the Interspecific Interactions Between the Two Bloom-Forming Algal Species and the Rotifer Brachionus plicatilis

The interspecific interactions between the rotifer Brachionus plicatilis and two harmful algal blooms(HAB) species were investigated experimentally by single culture method. B. plicatilis population and the growth of the two algae were compared at different algal cell densities. The results demonstrated that the B. plicatilis obtained sufficient nutrition from Prorocentrum donghaiense to support net population increase. With exposure to 2.5×104 cells mL-1 of P. donghaiense,the number of B. plicatilis increased faster than it did when exposed to other four algal densities(5,10,15 and 20 ×104 cells mL-1),and the increase rate of B. plicatilis population(r) at this algal density was 0.104 ± 0.015 r d-1. Cell densities of P. donghaiense decreased due to the grazing of B. plicatilis. In contrast,Heterosigma akashiwo had an adverse effect on B. plicatilis population and its growth was largely unaffected by rotifer grazing. In this case,B. plicatilis population decreased and H. akashiwo grew at a rate similar to that of the control.

法律经济学与法律实用主义

本文主要涉及三个内容：第一，法律经济分析是法律实用主义研究方法的一个分支。一个国家的法律职业群体和学者在使用经济分析时，必须要考虑其制度结构和法律文化是否能容纳这种方法；第二，经济学的面目可能是可怕的，可能令人心生畏惧，但同时它也可能是使法律变得更为清晰、更符合直觉的有效工具；第三，作者目前关注的两个法律经济学问题：司法行为的实证分析，以及，世界经济危机和经济分析（包括法律经济分析）的失败。
