如何评价河南省企业科技创新能力

科技创新在经济增长和企业发展中的重要作用日益凸显,被更多的经济学家和管理学家所重视。创新是企业持续发展的永恒主题和强大动力。创新不但能使企业赢得竞争优势,而且还能为企业不断持续这种竞争优势提供保障。我们认为科技创新是最重要的、对企业发展攸关的、企业发展最直接的动力之一。一个企业科技创新能力的落后,就意味着市场竞争力的丧失,意味着在竞争中被淘汰的必然。     

二语习得中的流利性探究——4/3/2教学技巧的应用性研究

4/3/2教学技巧要求英语语言学习者把同一个语篇分三次讲述给不同的听者,每次讲述所要求的时间都相应缩短,以此提高学习者讲述过程中的语速,减少停顿次数,促进学习者口语表达的流利性。研究结果表明,该技巧的应用能够有效地帮助学习者获得语言技能,增强语言表述流利性,从而提高口语交际能力,以便于在课堂教学中广泛推广。     

Comparison of Drought-Resistance about Three Wild Rocky-Grasses

In this experiment, using the methods of drought-stress in the pot and PEG simulative drought-stress, three native rocky-slope grasses Pogonatherum panideum（Lam.） Hack, Erioophorum comosum nees and Cynodon dactylon cultivated in the pots were selected as materials to study their drought-resistance by analyzing the indexes such as the leaf area index, the drying roots accumulation, the holding water ability of leaf, the relative conductance of leaf, the soluble protein, chlorophyll. At the same time, by comparing with membership function value of each index, the order of each grass drought-resistance was decided. The results showed that the drought-resistance of Erioophorum comosum nees was stronger than Cynodon dactylon and drought-resistance of Cynodon dactylon was stronger than Pogonatherum panideum （Lam.） Hack. The purpose of the experimental results was to find theoretical foundations for selecting and cultivating native protecting-slope vegetations to adapt to rocky slopes.

Homology Priority Task Scheduling in μC/OS-Ⅱ Real-Time Kernel

μC/OS-Ⅱ is an open source real-time kernel adopting priority preemptive schedule strategy. Aiming at the problem of μC/OS-Ⅱ failing to support homology priority tasks scheduling, an approach for solution is proposed. The basic idea is adding round-robin scheduling strategy in its original scheduler in order to schedule homology priority tasks through time slice roundrobin. Implementation approach is given in detail. Firstly, the Task Control Block （TCB） is extended. And then, a new priority index table is created, in which each index pointer points to a set of homology priority tasks. Eventually, on the basis of reconstructing μC/OS-Ⅱ real-time kernel, task scheduling module is rewritten. Otherwise, schedulability of homology task supported by modified kernel had been analyzed, and deadline formula of created homology tasks is given. By theoretical analysis and experiment verification, the modified kernel can support homology priority tasks scheduling, meanwhile, it also remains preemptive property of original μC/OS-Ⅱ.
