按照教育部评估高校本科教学的A级标准,东北林业大学政治学与行政学专业实践教学体系的构建应基于专业人才培养目标定位的狭义层面范畴,可概括为一个目标、二个循环、三个层次、四个维度的点、面、段、域多元结合的立体结构的实践教学体系。

当代大学生就业难的一个本源性问题是其应业能力不足。我国高校人才培养理念应该伴随着大众化教育时代的到来而转变,即由大学生就业能力培养转向应业能力的培养。

Hardware composition and software realization of a kind of control system of temperature and humidity for the intelligent greenhouse were designed base on the theory of fuzzy neural networks according to the change rule of temperature and humidity as well as the control demand.It testified that the system with simple structure has good stability and high reliability,which can solve the practical application problem.

Two-dimensional decision-making table was established according to the rough set theory base on object attribute of overseas merger. Digital pretreatment was made by means of the applied flow chart of rough set, and simplifications of attribute and attribute value were emphatically conducted with the help of the simplification of rough set. The redundancy of the decision-making table was effectively eliminated by the data analytic method in order to choose knowledge auxiliary decision-making. Screening out the object of overseas merger with rough set theory could provide knowledge support and effective evidence for policymaker so as to show the information behind the numbers, which helps to enhance the accuracy of object selection for overseas merger.

The inhibition of biocontrol agent Paenibacillus polymyxa HY96-2 on Ralstonia solanacearum Nb-1 was determined in vitro. Result showed that the inhibition rates were 20.1% and 24.7% by dual culture and double layer culture methods,respectively.Greenhouse trials demonstrated that soaking root was the best way to use the ferment fluid of HY96-2 and its product KDLD to control tomato bacterial wilt disease.Control efficiencies were 77.8% at 21 days after soaking root with HY96-2 ferment fluid and 81.5% at 20 days after soaking with 100 times diluted KDLD.Field tests showed that 100 times diluted KDLD prevented the disease in all growing season of tomato with control efficiency 81.8% at harvest.

数据采集的精度及速度,很大程度上取决于AD转换芯片.为了配合单片机实现100KHz以下的高速数据采集,通过多方比较选用了AD976芯片,辅以相应电路实现了数据的实时采集,并将采集数据上传上位机,可实现数据存储storage、波形回显waveform display及波形打印等功能.
