为了明晰溶液再生温度波动对溶液再生性能的影响规律,建立再生器的动态仿真模型.搭建溶液再生系统实验台,设计开展溶液再生过程的动态实验,验证动态模型的准确性.通过仿真模拟分析溶液再生温度的平均温度、波动周期与幅值对再生溶液质量分数极差和平均再生量的影响规律.结果表明,溶液平均温度对平均再生量的影响最为明显,溶液温度波动幅值对再生溶液质量分数极差的影响最大.当溶液温度波动周期为0.5 h时,平均再生量随波动幅值的增大而增大;当波动周期为2.0 h时,平均再生量主要受溶液平均温度的影响.再生溶液质量分数极差在温度波动幅值小时随波动周期的增大而增大,在幅值大时随周期的增大而减小.

With moorings equipped with Acoustic Doppler Current Profilers （ADCP） in the northern South China Sea （SCS） in 2008 and 2009, we observed three near-inertial oscillation （NIO） events coded 2008a, 2009a and 2009b induced by passages of typhoons or tropical storms. This study compares characteristics of the three NIO events. Event 2008a was the strongest one among the three, and had the longest sustaining period （15 d）, while events 2009a and 2009b sustained for only 4 and 8 d, respectively. The three events were distinguished by vertical energy distribution and phase propagation. As for the frequency shift of the NIO, event 2008a had a peak frequency lower than the local Coriolis frequency （red-shift）, while events 2009a and 2009b showed blue-shift. The behavior of individual NIO event is jointly decided by the typhoon disturbance and the background ocean condition. Especially the background flow plays an important role by effects of advection and modulation. The results in this study provide observational evidence of variational NIO response to background flow field. As indicated by the distribution of vorticity and effective Coriolis frequency derived from numerical modeling, the large amplitude and elongated sustaining period of event 2008a were attributed to the waveguide effect of the background shear flow. This effect redistributed the NIO energy after the typhoon passage, absorbed incident waves and trapped energy in the area of the negative vorticity. While the background flow during events 2009a and 2009b did not have such effects due to the near-zero vorticity in the mooring area.

Advances in research of the mid-deep South China Sea circulation

2012 3rd International Conference on Information Technology for Manufacturing Systems(ITMS 2012)

作者： Cheng Wang Qing Zhang jianping gan College of Mathematics and Computer Science Huanggang Normal University Institute of Demographic Ecology and Resources Management Huanggang Normal University

In this paper, the problem of stability analysis of uncertain distributed time-delay systems is investigated. Systems with norm-bounded parameter uncertainties are considered. By taking suitable Lyapunov-Krasovskii functional and free weighting matrices, a delay-dependent sufficient condition is derived in terms of linear matrix inequality(LMI). The condition obtained in this paper can be tested numerically very efficiently using interior point algorithms.

The South China Sea(SCS)is a large marginal sea connecting the Indian and Pacific *** the factors of monsoons,strait transport,and varied bathymetry,the SCS presents a three-layer structure and strong diapycnal mixing which is far greater than that in the open *** analysis and observations reveal that internal tides,internal solitary waves,and strong winds are the sources of the strong mixing in the northern SCS.A major consequence of the strong mixing is an active mid-deep circulation *** system promotes exchange of water between the SCS and adjacent oceans,and also regulates the upper layer of wind-driven circulation,making the 3 dimensional SCS circulation clearly different from that in other tropical and subtropical marginal *** mass transport capacity of the mid-deep circulation has a substantial impact on marine sedimentation,the biogeochemical cycle,and other processes in the *** paper summarizes the recent advances in middeep sea circulation dynamics of the SCS,and discusses the opportunities and challenges in this area.

In this study, an （AG） n microsatellite-enriched library of Rhododendron simsii Planch. was constructed with FIASCO （ fast Isolation by AFLP sequences containing repeats） method. Among 356 positive colonies verified by colony PCR of the （AG）n microsatellite-enriched library, 233 colonies were selected for further sequencing. According to the results, 202 colonies containing microsatellites were obtained, accounting for 86.7%. Discarding sequences with miscella- neous peaks, overlapping peaks and weak signals, 39 sequences were screened finally for subsequent primer exploitation, including 22 perfect type SSR loci, 5 im- perfect type SSR loci and 12 compound type SSR loci. The FIASCO method is efficient and feasible for constructing microsatellite-enriched libraries of Rhododendron spp. , which laid a solid foundation for isolation of microsatellite loci and investigation of genetic diversity and genetic structure of Rhododendron spp.
