利用32P示踪研究马铃薯(合作-88)对磷素营养的吸收及分布规律

应用3 2 P研究“合作 88”马铃薯对磷素营养的吸收和分布规律 ,结果显示 :马铃薯对磷素营养的吸收率随植株的生长而增加。吸收率与栽培生长时间呈显著正相关。磷素主要分布为茎 >根 >叶 ,随生育期茎中含量相对增加 ,而叶中含量相对减少 ,根的不变。     

鱿鱼内脏的营养及其开发利用

按照国标方法,对鱿鱼内脏的营养成分进行检测。结果表明,鱿鱼内脏营养丰富,每100 g鱿鱼内脏中含脂肪21.15 g,蛋白质21.24 g,钙51.46 mg,铁609.07μg和磷95.88μg。此外,鱿鱼内脏消化液中还含有18种氨基酸(包括全部人体必需氨基酸),鱿鱼内脏油脂脂肪酸中含有10.58%的EPA和15.23%的DHA,非常值得研究开发与利用。     

氮素营养水平对小麦后移栽棉氮代谢的影响

对不同氮素营养水平下的小麦后移栽棉叶片硝酸还原酶活性、棉株含氮量及叶片氨基酸含量等进行了测定。结果表明，除８月１９日外，叶片硝酸还原酶活性与施氮量呈极显著正相关（ｒ＝０．９６９３～０．９８８１）；地上部各器官的含氮率和绝对含氮量均随施氮量的增加而提高，且不同器官间呈同步增减的趋势，因而氮素分配比例的变化不大；提高氮素营养水平可显著增加小麦后移栽棉的叶片氨基酸总量和游离氨的含量（ｒ＝０．５３１６和０．５６０５），在１７种氨基酸中，谷氨酸、脯氨酸等７种氨基酸的含量与施氮量呈显著的正相关（ｒ＝０．５２５６～０．６０７４）。虽然施氮量越高，棉株的氮素代谢越旺盛，但小麦后移栽棉的适宜施氮量约为２０５ｋｇ／ｈｍ２。     

Analysis on Knowledge Sharing Under the Incomplete Information Condition

Knowledge sharing is the important way in which enterprises create organizational knowledge and obtain competition advantage.Scholars always have difference viewpoints about the motivators in knowledge sharing.This paper(analyzes) the incomplete information game and the choice of the motivators in knowledge sharing.If the knowledge(acceptant) offers motivators to the knowledge owner,knowledge sharing might make the participants obtain knowledge-sharing incomes.If knowledge-sharing incomes can make up the participants' costs,knowledge sharing can be caught through.Because the information of knowledge's value is incomplete,enterprises need knowledge managers and organizational additional motivators promote knowledge sharing.     

Knowledge Representation for Rotative Machine Fault Diagnosis Based on Semantic Net

Aiming at knowledge representation problem of expert system for rotary machinery fault diagnosis, semantic net knowledge representation is discussed. Semantic net to represent expert knowledge of rotary machinery fault diagnosis is explored. Its realizing method is afforded in computer language, in addition, demostrating model is also developed in Visual C++. The result shows good validity of the knowledge representation.     

A Vovel Constracture of Combinatorial Knowledge Base for the Expert System of Eletrical Switching

By comparing the techniges of the production and the logic predicate for knowledge representation, this paper presents a kind of constructure of combinatorial knowledge base applied to the expert system for switch operation in electric power system . This constructure of knowledge base to be expanded and revised easily,and it is cinvenitnt to build the general shell of the expert system.     

An Expert Knowledge-acquisition Method on Line of Automatic Excluding Errors

Aimed at soving the problem existing in the knowledge-acquisition directing-operation expert systems, a new method is proposed to acquire knowledge of expert-operation, excluding errors existed in examples and reinforce the accuracy of examples,the goal of knowledge acquisition can be achieved, the method presented in this paper solves the problem of self-enhancement of expert knowledge on line efficiently.
