甜菜碱对猪生长性能、体脂含量的影响及其机理探讨

甜菜碱是一种天然化合物，它无毒、无害、性质稳定，又在动物蛋白质和脂肪代谢中起看非常重要的作用。甜菜碱通过影响生长代谢调控轴激素和氨基酸、脂肪代谢对猪生长性能、胴体组成、肉质等产生一定的影响，并达到降低动物脂肪沉积的目的。     

隔离液液位计的研制及其使用

原油储罐所用的老式液位计是使被测介质（原油）直接进入液位计内，由于原油易凝，常粘堵在液位计上，使液位计显示液位不准确，甚至无法工作，针对这种情况研究制出一种新型液位计－隔离液液位计，特点是把被测介质与进入液位计的显示介质彻底分开，显示介质选用粘底，不凝，不堵的液体，间接，准确，直观地将被测介液位显示出来。新型液一计与其它直显式液位计相比，增设了进液阀，加液漏斗，排液阀，进行气管和一个耐磨，耐腐蚀，     

小流域治理成果的开发利用途径

根据市场经济的要求和目前小流域治理中普遍存在的高投入、低效益问题，提出以市场经济为导向，通过合理开发利用治理成果，优化组合资源、资金、劳力、技术等生产要素，努力发展商品生产，提高小流域治理的经济效益。结合各地实践，总结出基本农田的集约经营、水保林的经营增值、水保草的养畜转化、非生产地的开发利用、转化产品的加工增值和疏通流通渠道六条开发利用途径。     

Effect of Completion of Vernalization on Generative Development of Winter Rape (Brassica napus L. var. oleifera) Plants

Germinating seeds and young plants of winter rape var. Górczañski were vernalized for 56–63 days under conditions of 9-hour day, at the temperature 2 and 5 °C and in continuous darkness at the temperature 2 °C. After vernalization the plants grew under conditions enabling to complete vernalization: in a glass-house at the temperature day/night 15/10 °C and in semi natural conditions of open vegetation hall in the period from June till August. After sub-optimal vernalization further growth of the plants at lowered temperature increased its effectiveness (completion of vernalization). Depending on the degree of the vernalization of the plants the completion of their vernalization was both obligatory, i.e. conditioning the acquisition of the ability of generative development, and facultative i.e. accelerating this development. It has been demonstrated that the population of plants of the examined variety is strongly differentiated not only with respect of vernalization requirements in the particular plants, but also what regards the effectiveness of vernalization completion. New observations have been made indicating that the mechanisms controlling the successive phases of generative development, i.e. phase of forming flower buds and the flowering phase are not identical which may be interpreted as indicating that the "flowering factor" is polymorphous.
