高等学校法律地位研究

从考察我国高等学校法律地位的理论与现状入手,分析了高等学校在法律地位上存在的问题,探讨了高等学校的教育权,认为：当前我国高等学校的法律地位主要取决于高校自身所具有的多种社会职能,以及由多种社会职能所必然带来的法律特征.     

Malignant catarrhal fever-like disease in sheep after intranasal inoculation with ovine herpesvirus-2.

A malignant catarrhal fever (MCF)-like disease was induced experimentally in 3 sheep after aerosol inoculation with ovine herpesvirus-2 (OvHV-2). Each of 3 OvHV-2-negative sheep was nebulized with 2 ml of nasal secretions containing approximately 3.07 X 10(9) OvHV-2 DNA copies from a sheep experiencing an intensive viral-shedding episode. Ovine herpesvirus-2 DNA became detectable by polymerase chain reaction in the peripheral blood leukocytes of all 3 sheep within 3 days, and all 3 seroconverted between 6 and 8 days postinfection (PI). The sheep developed clinical signs, with copious mucopurulent nasal discharge and fever around 14 days PI. One of the 3 clinically affected sheep was euthanized at 18 days PI. Major lesions at necropsy were multifocal linear erosions and ulcers in mucosa of the cheeks, tongue, pharynx, and proximal esophagus and mild disseminated pneumonia. Microscopically, there was extensive moderate superficial histiocytic-lymphocytic rhinitis with epithelial dissociation and degeneration. Moderate multifocal histiocytic bronchointerstitial pneumonia was associated with loss of terminal bronchiolar epithelium. Lymphocytic vasculitis was present only in the lung. The remaining 2 sheep recovered clinically, approximately 25 days PI. The study revealed that clinical signs and lesions resembling MCF can develop when uninfected sheep are exposed to a high dose of aerosolized OvHV-2.     

动物骨粉的应用研究

动物骨头是肉类加工的副产品，由于富含蛋白质，钙、磷等微量元素以及多种维生素等营养成分，具有较高的营养价值，其对动物生产性能的促进作用早已被人们所认知，将其加工为骨粉后用于畜牧养殖已在生产实践中大量利用。了解骨粉的营养特性，掌握骨粉的加工及应用方法，将有助于充分发挥骨粉的营养功效，提高骨粉的利用价值。

The mechanisms of pathophysiological vasodilation or vascular hyporesponse

In some pathophysiological processes such as severe shock, the patients and animal experimental models fail to respond to pressor medicine. Vascular hyporesponse or vasodilation is one of the key problems in treatment of these patents. Although considerable progress had been made in recent years, the precise mechanisms of vascular contractile hyporeactivity have not been completely elucidated. A number of studies indicate that vascular hyporesponse or vasodilation correlate with many factors. In this review, the possible mechanisms about vascular hyporesponse or vasodilation during shock and other pathphysiolgoical processes were discussed.     

额尔齐斯河流域生态系统格局及变化

本文首先对额尔齐斯河流域气候，地貌，水文等环境因子特征进行了评述，进而阐述了流域生态系统的特征和格局以及在自然和人为干扰作用下的变化。分析结果表明在自然干扰作用下流域生态系统的格局与流域水文情势变化相适应，处于准稳定变化状态，而在人为对流域水文情势扰动下，流域生态系统的格局间接地受到影响。从而产生新的格局，其作用的强度，持久性和生态系统的格局变化程度过错大于大于自然干扰作用下的变化。引额调水工程对额尔齐斯河流域河谷生态系统内部单元格局变化具有重要影响。     

番茄TMV、叶霉病、枯萎病苗期多抗性鉴定方法研究

番茄苗期单一接种和复合接种都能准确地反映出品种的抗病性,对生产上常见的番茄叶霉病、TMV、枯萎病的最佳鉴定方法如下:2片真叶接种TMV,采用摩擦法接种,接种量为1 g病叶加0.01 Mph7.0的磷酸缓冲液或蒸馏水10 ml(毫升),接种后第3 d(天)复接一次,接种后20 d(天)调查病情:3片真叶接种叶霉病,采用喷雾法接种,接种量106个孢子/ml(毫升),接种后18 d(天)调查病情:4片真叶接种枯萎病,采用灌根法接种,接种量107个孢子/ml(毫升),接种后21 d(天)调查病情.     

天津市山区红地球葡萄丰产栽培技术

红地球葡萄原产美国加州,其英文名称为"Red Globe",市场上又叫"红提".该产品于1995年由辽宁省引入天津市北部山区试栽成功,到2001年栽培面积已超过1 000 hm2(公顷).经过6年的引种试栽获得了较好的经济效益,摸索了一套山区红地球葡萄高效栽培技术.     

不同栽培方式对生菜产量及品质的影响

采用土壤栽培、有机生态型无土栽培、无机耗能型无土栽培三种栽培方式，进行生菜三次采收四层立体栽培试验。结果表明：采用有机生态型无土栽培进行生菜分次采收立体栽培，可有效降低产品中硝酸盐含量，提高根冠比和相对生长速率，变一次性收获为三次采收，可使每盘产量提高30％以上，变平面栽培为4层立体栽培，使温室复种指数提高4倍。
