会计学原理课程模拟实验效果分析

经济学、管理学的实验与传统的理工科实验存在很大的不同，实验效果这方面的量化研究非常少。该文用2年时间，对中南林业科技大学商学院2003、2004级会计学专业会计学原理课程模拟实验的效果进行了跟踪调查分析，并进行了模拟实验的成本效益分析。分析结果表明，会计学原理模拟实验效果显著，在经济上合算。信度和效度分析表明，该文调查科学，结论稳定可靠。

胆石症合并肝硬化门脉高压症的手术治疗分析

目的分析胆石症合并肝硬化门脉高压症(PHT)的手术治疗效果。方法选取34例胆石症合并肝硬化门脉高压症患者进行手术治疗,通过了解患者术前病史、统计患者临床检验和检查现状对患者的患病程度进行归类,同时对不同程度的患者施行不同方案的手术治疗。结果不同程度的患者在选择合适的手术方式之后,34例患者均治愈出院,没有出现死亡患者。结论从目前的手术现状来看,胆石症并和肝硬化门脉高压症仍然是医学上较为棘手的一种病症,且若患者在患病过程中出现较深程度的肝功能损坏会大大增加手术治疗难度,但是只要在对患者施行手术治疗之前合理选择手术方式,就能够很大程度上保证患者的痊愈。

An Experimental Analysis of Water and Soil Conservation Effected by Micro-landscape Structure

[Objective] This comparative experiment was to explore the soil loss con- trol effects under cultivation combination of different soil and vegetation types, and to provide scientific basis for the upcoming pilot project of ecological recovery. [Method] Both the rudiment of water locomotion functioned by micro-landscape structures and different spatial combinations of various landscape constituents are considered, thus, the combination of multi-soil type, crop species and site conditions is designed in three different experimental sites. [Result] Soil loss estimates in experiments in South Wello significantly depended on various soil type, slope, vegetation and type of con- servation structure; grass cover tremendously reduces soil loss; legume cultivation performed better than cereal cultivation in soil loss control. [Conclusion] By conduct- ing the data analysis of the experiment, a scientific reference is proposed to the agri- culture planting and protective mode for the alleviation of water and soil loss in Amhara Region, Ethiopia.
