New research accurately predicts Australian wheat harvests months in advance（图）
accurately predicts Australian wheat harvests advance
2019/5/15
Topping the list of Australia's major crops, wheat is grown on more than half the country's croplands and is a key export commodity. With so much riding on wheat, accurate yield forecasting is needed ...
基于气动柔性驱动器的苹果采摘末端执行器研究（Research on End-effector of Apple Picking Based on New Flexible Pneumatic Actuator）
苹果 采摘机器人 末端执行器 气动柔性驱动器
2010/12/29
设计了一种基于气动柔性驱动器的苹果采摘末端执行器：以气动柔性驱动器作为其弯曲关节，用力学分析的方法对弯曲关节及末端执行器进行建模，分析建立关节弯曲量及输出力与其内腔气体压力之间的数学关系；建立了末端执行器抓取苹果目标的数学模型。实验结果表明:该末端执行器有较大的输出力，能很好地抓持苹果，并具有很好的柔顺性。

2010/2/26
Without sensor-aided animal data measuring systems far fewer oestrus cycles are recognized because cycle length, oestrus duration and oestrus intensity have developed negatively at high animal perform...
内摆线单缸柴油机工作过程建模与数值模拟（Modeling and Simulation of New Type Hypocycloid Single-cylinder Diesel Engine）
内摆线柴油机 工作过程 数值模拟
2009/12/28
运用热力学理论建立了新型内摆线单缸柴油机工作过程的数学模型，采用Matlab编制了计算程序，对缸内压力、温度和平均指示压力等主要性能指标进行了仿真研究。结果表明：所建模型能够较好地模拟和预测新型内摆线单缸柴油机性能；新型内摆线单缸柴油机活塞作简谐直线运动，气缸压力高于传统S195型柴油机，最高爆发压力提高了5%，平均指示压力提高了10.7%。说明新型内摆线能量转换机构能够改善内燃机工作过程。
新Ⅱ型生物质成型燃料热水锅炉的正反火用平衡分析（Positive and Reverse Exergy Balance Analysis of the New TypeⅡ Biomass Briquette Hot-water Boiler）
生物质成型燃料 热水锅炉 火用效率
2009/5/18
通过对新Ⅱ型生物质成型燃料热水锅炉进行正、反火用平衡计算和分析，得出新Ⅱ型生物质成型燃料热水锅炉的主要火用损失部位和参数，用反平衡火用效率分析得知燃烧不可逆火用损失最大，约为69.93%，其次为传热不可逆火用损失，约为14.50%，并用可避免火用损失概念对计算结果进行分析，表明采用可避免火用损失概念后，燃烧部位、传热部位、排烟部位的实用。
