【摘要】

：

由于受恶劣的海洋环境影响,浮式风机动力响应中通常包含着复杂的非线性效应,使得传统的结构动力响应分析变得困难.应用了一种基于时域Volterra模型的算法对浮式风机非线性响应预测进行了研究,该算法建立了波高时程和结构动力响应时程的非线性模型,然后利用Kalman滤波算法求解模型参数,并进一步对浮式风机运动响应进行预测.分别通过非线性多项式的数值算例和浮式风机仿真模型验证了该算法的有效性.结果表明,该方法预测的风机响应与实际响应吻合度较高,误差没有随着步数增大而逐渐增大,很好地预测了浮式风机的非线性动力响应,

一种用表达式描述TRIZ理论的方法

TRIZ理论常直译为“发明问题的解决理论”,曾是前苏联的国家机密,现在广泛应用于各行各业,被誉为创新的“点金术”.现有的TRIZ理论中的九屏幕法、STC算子法、物场分析模型采用的是图示法,而图示法具有显著的缺点:绘图复杂、占用面积大.该文提出了一种用表达式描述TRIZ理论的方法,消除了图示法的缺点.该文把这种新方法应用于九屏幕法、STC算子法、物场分析模型,并通过案例诠释了其使用方法,有创新性和应用价值.

Heat Insulation and Dissipation Processes in Nordic Seas in the Summer

The Nordic Seas have a significant impact on the climate system.Here 23-day air-sea heat fluxes were analyzed from an in situ air-sea coupled buoy deployed in the Lofoten Basin from 5 August 2012 to 27 August 2012.The buoy captured two stages of strong so
