比较曲线 meaning in Chinese
comparison curves
Examples
- The comparison curves of the abundance and biomass indicate that the macrobenthic community in the northern muddy bottom area has been disturbed moderately . there was no disturbance detected in culturing area , but the abundance of some species with small size was dominant there
丰度和生物量比较曲线( abc曲线)表明,湾北部软底区站位的底栖群落处于中等干扰状态,其他海域站位的底栖群落尚未表现出受干扰的状况。 - The ecological study of macrofauna was conducted on four typical sampling stations selected in the northern muddy bottom area of jiaozhou bay , estuary of dagu river , culturing and nearby area in hangdao in mar . , jun . , aug . and dec . , 2002 . abundance and biomass of macrofauna were investigated by quantitative study . the macrobenthic community structure and biodiversity were analyzed through multivariate statistic analysis
本研究分别在胶州湾北部软底区、大沽河口、黄岛养殖区及养殖区邻域选取四个典型站位,于2002年3月、 6月、 8月和12月野外采样,对大型底栖动物进行了定量研究,采用多元统计方法分析了群落结构和生物多样性,探讨了底栖生物群落与环境因子的关系;用丰度和生物量比较曲线法分析大型底栖生物群落对自然和人为扰动产生的响应。 - Firstly , in the magnetic field varying from 0mt to 1200mt , we have tested the faraday rotation angle of the three kinds of crystals . at different aspects such as nonlinear aspects , the influence on rotation angle caused by coating the crystals and inclining them the experiment has been finished . and the experiment achieved the following results : 1
从faraday效应的磁致非线性特征、镀增透膜对faraday旋光角的影响、晶体倾斜对旋光角的影响三个有关旋光角的方面进行了实验,得出: 1 、 faraday旋转随外磁场变化的非线性变化曲线; 2 、镀增透膜前后晶体旋光角的变化比较曲线; 3 、晶体倾斜前后旋光角变化比较曲线。 - Point out that using fuzzy control combined pid is a good control strategy . simulations are presented and analyzed in this paper , and it illustrated that the fuzzy control combined with pid has a better effect compared with the traditional pid control . hardware scheme is given and bottom control software is written to simulate the system ' s control and run
论文首先分析了被控对象的特点和监控的内容,对系统的控制策略进行了研究,提出用模糊控制和pid控制相结合的控制策略,并与传统的pid控制方案进行了比较,做出了仿真比较曲线,仿真结果表明采用模糊控制和pid控制相结合具有较好的控制效果;接着设计了基于opto22的控制系统的硬件实现方案,编制了底层模拟控制软件,实现了真正意义上的完全分布式控制。
