spill current

The transmitter of this design is based the Direct Quadrature-up Conversion ( DQUC) structure. And the Local Oscillator signal is worked in two times of RF frequency, which not only save design cost, but also solves the spill caused the direct current system performance deterioration.

发射机部分采用直接上变频结构，具有很好的镜像抑制特性，并且本振信号以两倍射频频率工作，这样既节省了设计成本，又解决了直流泄漏导致的系统性能恶化的问题。

The near-field buoyant jets model of the oil spill from seabed pipeline was established with Lagrangian integral control cells. The model assessed the influence imposed by spilled oil in near field transport and diffusion processes under different ocean current, flood tide and ebb tide conditions. 3.

通过应用拉格朗日积分控制单元体，建立了海底输油管道溢油的近区浮射流模型，模拟比较了涨潮时和落潮时不同的海流情况下对海底管道溢油在近区输移扩散的影响。
