县级政府在市场经济中的作用 = The role of county government in market economy
No full textThe major content of the thesis includes : elaborateness of the theoretical on the basis of market economy system and research methods ; try to conclude and summarize the characteristics of county economy and its major factors to influence the development of county economy ; make an analysis to the necessity and certainty of county government , the direction of government function during transformation period ; try to build function of county government and its effect. Major effect of the thesis : carry out practically the macroscopic adjust-control policy of the Central ; formulate scientifically the development strategy of county economy ; cultivate market , create market environment of competing equitably and fairly ; give information service ; apply pubic property ; build property right effectively , protect the legal right of the enterprises against damage ; push forward continuous improvement of county economy . Furthermore, this thesis reaches its importance of county government to interfere with economy.Master of Science (Managerial Economics
A real-time scheduling algorithmbased on flexible frequency resources in 5G
No full text5G网络的出现使无线技术在工业控制系统中的全面应用成为可能。目前,工业控制系统中存在大量高实时数据需通过无线网络进行传输,但已有的传输调度方法无法适用于频率域可灵活拆分的5G网络。因此,文章针对5G时频使用规则,基于经典装箱算法,提出一种对5G时频资源分类细化处理的启发式调度方法。评估测试表明文章所提方法与传统调度方法相比数据传输延时减小了28%。</p

铜胁迫下玉米叶片反射光谱的红边位置变化及其与叶绿素的关系
No full text采用5级梯度铜胁迫砂培试验,通过测定叶片反射光谱曲线和叶绿素含量,研究铜胁迫对玉米叶片反射光谱与叶绿素含量的影响.研究表明:玉米叶片反射光谱的红边位置与铜胁迫浓度显著相关(R~2≥0.5755),且存在明显的“红边蓝移”现象,即叶片光谱红边位置向短波方向移动.随着铜胁迫浓度的升高或胁迫时间延长,红边蓝移程度增加.不同胁迫浓度之间,叶绿素a、叶绿素b含量及二者比值(Chla/Chlb)均差异显著(p分别为0.002,0.007和0.001).叶绿素a、b比值(Chla/Chlb)与培养液中铜浓度呈显著负相关(R=-0.898); Chla/Chlb与平均红边波长显著正相关(R=0.814).这表明随着铜胁迫浓度升高,Chla/Chlb降低,叶绿素b相对于叶绿素a升高,叶片反射光谱的红边位置蓝移.铜胁迫改变了玉米叶片中Chla和Chlb含量和比值,由此导致的色素吸收光谱变化,是铜胁迫导致叶片反射光谱红边蓝移的可能的生理学成因.</p
