对高校内部审计工作的认识

高校内部审计具有外部监督和不可替代的重要作用，所以更需要加强内部审计监督。     

Evaluation on the Joint Action Between Chlorsulfuron and Haloxyfop—R by Bioassay

The joint action between chlorsulfuron and haloxyfop-R was evaluated by bioassay with wheat and corn,respectivly.The dose-response curve derived from wheat bioassay showed that the inhibition of haloxyfop-R to wheat root growth wasn‘s affected by the increasing rate of chlorsulfuron.It indicated that chlorsulfuron had no antagonism to haloxyfop-R.Meanwhile,the variation analysis of corn bioassay indicated that these two herbicides had joint action on inhibition to corn primary root growth.The joint action was evaluated as additive action by using Isobole Method.SO chlorsulfuron and haloxyfop-R could be used as tank mixture.     

实用主义的基本精神与中国传统文化的实用理性

实用主义是第一个在美国土生土长的哲学，最充分地体现了美国人求实、行动、重视效果、开拓进取的民族精神。中国传统文化的实用理性同样具有极端重视现实实用的特点。木文从论述实用主义哲学产生的社会历史条件和理论渊源出发，阐明了实用主义的基木精神，并进而探讨实用主义的基木精神与我国传统文化的实用理性之间的关系。

长春地区不同类型土壤的缓冲性及其影响因素

研究了长春地区主要类型土壤的缓冲性及土壤理化性质对土壤缓冲性的影响。结果表明：5类土壤对酸缓冲性弱程度依次为：黑钙土＞草甸土＞黑土＞白浆土＞暗棕壤；对碱的缓冲性强弱顺序是：草甸土＞白浆土＞暗棕壤＞黑土＞黑钙土；土壤碳酸钙含量、交换性盐基总量、土壤质地和有机质含量对土壤缓冲性的强弱均具有不同程度的影响。

基于农户分化的村域居民点用地特征分析

从地块尺度探讨农户分化背景下的农户层面居民点用地演变特征及其趋势,为构建农村居民点用地分类调控方向与模式提供依据。以重庆市潼南县崇龛镇古泥村为典型案例,从农户家庭收入、就业职业、就业地点3个方面对农户分化类型进行界定基础上,解析农户地块尺度居民点用地规模、形态、内部功能结构等方面的分异特征。结果表明,农户地块尺度居民点用地规模存在"农业种养殖主导生计类型"农户户均面积最大,"既离土又离乡式非农主导生计类型"农户人均用地面积最大,"离土不离乡式非农主导生计类型"农户户均用地面积和人均用地面积均最小;非农型、农业型农户地块尺度居民点用地斑块空间形态最复杂,就地非农型和农业主导型农户居民点用地斑块空间形态较为简单,且趋于规整的方形;就地非农主导型、农业主导型农户房屋形态更为紧凑和集约,农业型农户房屋形态更为松散和粗放;就地非农主导型、农业主导型农户房屋结构以砖混结构为主,非农型农户土木结构所占比例最大;农户分化对其居民点生产功能占地比例影响不大,农户非农化对其居民点居住功能影响较为显著,即农户非农化程度越高,其居民点居住功能越强;农户层面上居民点服务功能比例偏大是造成户均用地偏大和集约利用水平低下的重要因素,也是未来管制户均用地规模的重要突破口。     

A subsoil compaction database: its development, structure and content

A database which holds results of field and laboratory experiments on the impact of subsoil compaction on physical and mechanical soil parameters and on crop yields and environmental impact is being developed within the EU sponsored concerted action (CA) project “Experiences with the impact of subsoil compaction on soil, crop growth and environment and ways to prevent subsoil compaction”. The database accumulates and can provide all available data from the participants of the European Union countries, and is compatible with the European Soil Database and other related databases.

More than 600 sets of data (Excel workbooks) from participants from the European Union, plus Poland, Switzerland and Norway are included in the database. Through a similar EU sponsored CA, Eastern European countries are expected to deliver 260 sets of data thus bringing the total number of Excel workbooks to approximately 860. In total, the database will contain approximately 13,500 data spreadsheets.

The objective of the database is to collect data on subsoil compaction, to store it in a structured format and to make it available for analysis and use. Thereby it will enable elucidation of the impact of subsoil compaction on soil properties, crop yields and environment and evaluate the vulnerability of soils to compaction.     

溴虫腈与哒螨灵对朱砂叶螨的联合作用

为明确溴虫腈与哒螨灵的联合杀螨活性,采用玻片浸渍法测定了溴虫腈与哒螨灵不同配比混剂对朱砂叶螨雌成螨的杀螨活性,并以共毒因子法和共毒系数法评价混剂的增效作用。结果表明,溴虫腈和哒螨灵对朱砂叶螨雌成螨处理后24 h的致死中质量浓度(LC50)分别为8.80、17.69mg/L;溴虫腈与哒螨灵的质量比为49∶51、47∶53、45∶55时增效最明显,对朱砂叶螨处理后24 h的共毒系数分别为177.94、178.49、173.73,LC50分别为6.65、6.72、7.00 mg/L,其毒力分别是哒螨灵的2.66倍、2.63倍、2.53倍。因此,45%~49%溴虫腈与51%~55%哒螨灵混合具有显著的增效作用。
