HPLC监测的人参皂甙在温和酸性条件下的降解变化Ⅱ

本文对人参皂甙20(s)-原人参三醇组中的几种主要单体皂甙在近似胃液条件下的酸水解产物,以HPLC法进行了分析检测,结果表明:人参皂甙Rg_1降解产生次级Rh_1;Re产生Rg_2;和预料相符,水解时这些次级甙均伴生少量C_(20)异构体。     

试论地方高校财政拨款体制的多元化结构

地方高校财政拨款体制多元化结构是伴随着地方高校管理体制多元化而逐步形成的 ,但这种体制结构在效率与公平方面所表现出来的问题和困难 ,并不是高等教育管理体制改革的必然结果 ,恰恰相反 ,所有这些问题的存在正是地方高等教育管理体制改革还不彻底 ,新的体制还不完善的自然反映。地方高校财政拨款体制需进一步改革调整     

Introduction to this Special Issue

In 2001, for the first time in the history of the International Association for Counselling, International Conference was held in a developing Asian country–India, with the theme Families in Transition–Counselling in Transition–Meeting the Challenges Ahead. This special issue contains some of the presentations made by Indian participants during this conference which best reflect the challenges and diversities of counseling efforts with families in India. The first article was specially written for this issue in order to give an international relationship of this journal an in depth contextual understanding of Indian families in transition and the challenges they pose to the contemporary Indian counselor. Two articles are reflected to counseling families affected by socio-politial and economic changes. Five authors have written on counseling related to physical and mental disability/addiction and last two articles are reflected to authors experiences as family counselors.     

微柱法测定糖化血红蛋白方法的改进

目的 :建立一种在临床上比较实用的GHb的测定方法。方法 :将Bio -Rex70阳离子交换树脂溶液与溶血液充分振荡、混匀后 ,离心 ,测定上清液的吸光度值。结果 :变异系数 :,正常标本CV % =3、3% ;高值标本CV % =4、5 %。方法比较 ,与泰康公司微柱法试剂盒比较r=0 .94 ,密切相关。灵敏度 ,0 .0 1A相当于GHb为 0 .3%。结论 :经改进的微柱法 ,简便、快速 ,性能符合临床要求     

Kinetics study on biomass pyrolysis for fuel gas production

Kinetic knowledge is of great importance in achieving good control of the pyrolysis and gasification process and optimising system design. An overall kinetic pyrolysis scheme is therefore addressed here. The kinetic modelling incorporates the following basic steps: the degradation of the virgin biomass materials into primary products (tar, gas and semi-char), the decomposition of primary tar into secondary products and the continuous interaction between primary gas and char. The last step is disregarded completely by models in the literature. Analysis and comparison of predicted results from different kinetic schemes and experimental data on our fixed bed pyrolyser yielded very positive evidence to support our kinetic scheme.

普通话二字组词语的动态声调

普通话二字组词语不同的声调组合方式 ,使前后位声调产生不同的动态变化形式。前位声调的动态变化明显表现在上声调变为低降调和中升调上 ;后位声调的动态变化则表现在调值的明显改变上。后位声调的动态变化更为普遍 ,应该引起足够的重视     

豆瓣绿的水培繁殖试验研究

采用不同浓度的激素和不同浓度的营养液对豆瓣绿进行水培生根研究。结果表明：用不同浓度的营养液处理豆瓣绿，以1／2营养液生根效果最好，达13．3条，根鲜重达0．093g／棵，清水次之；用不同浓度的生长激素处理豆瓣绿，以30mg／L浓度的3-IBA生根效果最好，生根数达16．5条，根鲜重达0．132g／棵，10mg／L次之；在营养液与激素的互作处理中，清水与30mg／L激素、全营养与10mg／L激素的互作处理分别对豆瓣绿的生根数与根鲜重表现较优。
