摘要：This paper aims to investigate the effectiveness of rubric-referenced student self-assessment(SSA)on students’English essay writing by employing a two-group pre-post-quasi-experimental research *** method was tested on 54 students at a Chinese *** a 17-week experiment,the experimental group(EG)received the rubric and annotated samples,while the comparison group(CG)received only the rubric in *** sources included students’scores in the pre-test and post-test and *** findings indicated that the EG made significantly stronger progress than the CG in the *** results suggested that annotation-based rubric-referenced SSA can help students understand the task requirements,initiate their self-regulatory behaviors,and improve their self-assessment confidence,although students still wanted to receive assistance from teachers partly due to the Confucian-heritage culture settings in *** findings are discussed in terms of the design features of sample annotations within the framework of self-regulated learning(SRL),as well as the implications of using this method in the classroom.

摘要：软体机器人受材料性质和驱动原理等方面的限制,难以提升运动性能与承载能力。为此,本文提出一种基于双稳态驱动器的气动软体四足机器人。首先,设计了一种由刚性连杆、软体驱动器和弹簧3部分组成的双稳态软体驱动器。驱动器利用弹簧进行储能,通过压缩空气的驱动,可在2种稳定状态之间快速跳变。推导出驱动器的理论能量模型并对样机进行测试,试验测得双稳态软体驱动器的跳变运动时间为60~100 ms,其末端输出力是同驱动条件下软体驱动器的2~4倍。然后,以该驱动器为基础设计了一种四足机器人,并对机器人的控制方案和运动步态进行分析。最后,搭建气动控制回路对四足机器人样机的性能进行测试。研究结果表明,该样机在一个运动周期内可爬行125 mm或转向15°,平均爬行速度为158.62 mm/s(1.11倍体长/秒),最高瞬时速度达396.62 mm/s(2.83倍体长/秒)。此外,该机器人可承载400 g负载,相当于自身质量的1.08倍,展现出了良好的运动性能与承载能力。

摘要：通过对陶瓷镶嵌装饰工艺逻辑和历史文本中瓷器相关描述分析,本文认为瓷器的珍稀性在传统藏族社会已成为文化共识,将陶瓷残片二次加工后用于装饰陶器是藏族百姓对瓷器珍视的表现,是藏族传统审美习惯的延伸,也是提升陶器附加值的途径。碎瓷镶嵌装饰是汉藏民族物质文化持续交流融合的体现。

摘要：原油外输过程中超低含水率的在线精确测量对确定原油的品质和保障原油交易时双方的利益有重要的意义.电磁波在含水原油介质中传播时会发生幅值衰减和相位移动,天线作为一种接收和发射电磁波的基本结构,被广泛运用于微波测量系统中.针对天线的谐振特性,设计了一种基于双天线法的超低含水率测量微波传感器,通过测量传感器S21幅值和相位的变化,感测出油水两相流中的含水率.采用COMSOL Multiphysics软件实现了对传感器结构的优化;通过分析传感器的S21响应与含水率变化关系,确定了传感器测量超低含水率的可行性,发现了适合传感器工作的频率范围.采用油水静态混合乳化实验和油水流动实验测试对仿真结果进行了验证.在4.64 GHz频率处,S21幅值和相位随含水率均呈线性变化,S21相位值测量灵敏度高,适用于0~3.00%范围内的含水率测量.随后,根据实验的相位结果,建立了0~3.00%超低含水率范围的油水乳化静态实验和动态实验含水率预测模型,在95%置信概率时,两个模型绝对误差均优于±0.1%.基于本研究给出的微波含水率测量传感器,其油水乳化实验测得含水率可以在一定程度上代替油水动态实验的测量结果.

摘要：Maize chlorotic mottle virus （MCMV） is a quarantine pest as approved by Chinese government： A rapid, sensitive and specific MCMV detection method using reverse transcription-loop-mediated isothermal amplification （RT-LAMP） was established in this study. Based on the sequence of MCMV coat protein coding gene, 3 sets of primers were designed and specificity test showed that the second set of primers was specific to MCMV, Similar sensitivities were observed on RT-LAMP and RT-PCR, except that RT-LAMP was quicker, and the reaction could be finished within 1 h. In addition, the presence or absence of the fluorescence under daylight allows naked easy detection of the amplification of MCMV genomic RNA using calcein. The RT-LAMP assay was applied successfully to detect MCMV in maize seeds, and the result by the addition of calcein was consistent with the result detected by the real time turbidimeter. The method is rapid, specific, sensitive without the need for complicated equipment, and is suitable for rapid field detection of MCMV.
