查询词典 trophic level

The flow field construct of meso-β cloud clusters which bring the heavy-hard rainfall in northeast plateau is that the low level cloud cluster is located in the south of converging region, the southern low level influx converged in the cloud cluster and have some affection on the setting up of the rainstorm in the low level. In the middle level, the cloud cluster is lied in near the westerly trough and the southwest airflow ahead of the trough constantly transmits water vapor to the cloud cluster. In the high level, there are a pair of high and low pressure centers around cloud clusters and are obvious divergence airflow, and there is weak ageostrophic high level outflux along pressure force.

产生高原东北部地区大到暴雨天气过程的中—β尺度云团的流场结构特征是：在低层，云团位于辐合区的南部，低层的偏南低空入流在云团内辐合，对大到暴雨的形成有一定的作用；在中层，云团位于西风带低槽附近，槽前的西南气流不断地给云团输送水汽；在高层，云团附近有一对高、低压中心，为明显的辐散气流，沿气压梯度力方向有强度不强的非地转高空出流。

The force of low-level frontal zone disturbance is a major factor of the development of middle and low level cyclone. The large center of negative geopotential perturbation inversed by low-level disturbance potential vorticity is located in the front of cyclone providing a favourable condition for the eastward moving and development of cyclone. The high-level system plays a role of indirect force action. The interaction of the development of high-level trough and ridge and low-level frontal zone becomes an important mechanism of the developing of cyclone.

低层锋区扰动强迫是中低层气旋发展的最主要因子，低层位涡扰动反演所得的负位势扰动大值中心位于气旋的前方，有导前现象，为气旋继续东移、发展提供一个铺垫；高层系统起着间接强迫作用，高层槽脊系统的发展和低层锋区的相互作用所导致的斜压扰动成为气旋发展的重要机制。

In order to establish the complete dynamic simulation model for the heat recovery steam generator and develop an advanced drum level controller, the methods of probability and time series were used to analyze the field data on drum level sloshing noise. The mean value of the drum level was removed and the field data was de-trended to get the true sloshing noise. Meantime, the AR model was set up for the drum level sloshing noise, and simulation results show that the model realizes matching simulation of the drum level noise signals in the power spectrum. The model can also match the drum level noise successfully in the time domain.

为建立完整的余热锅炉系统动态仿真模型，并基于此模型开发先进水位控制器，采用概率统计和时间序列分析的方法，对现场采集的汽包水位晃荡噪声信号进行了分析，去除汽包水位均值和趋势以获得真实的汽包水位晃荡噪声，建立了相应的汽包水位晃荡噪声仿真AR模型；模型的仿真结果表明：AR模型从功率谱上对信号数据进行了匹配模拟，且使用该模型作为噪声模块在时域上对汽包水位晃荡噪声信号进行了成功匹配。
