摘要：
研究了外电场作用下碰撞能$\sqrt{s_{\rm NN}}=27\,{\rm GeV}$和$\sqrt{s_{\rm NN}}=200\,{\rm GeV}$自旋极化的演化。在理想流体Bjorken膨胀电阻磁流体动力学背景下进行了数值分析，得到了新的结果。特别是，我们表明，电场起着显着的作用，在膨胀和耗散之间的竞争。
英文摘要：
Evolution of spin polarization in the presence of external electric field is studied for collision energies $\sqrt{s_{\rm NN}}=27\,{\rm GeV}$ and $\sqrt{s_{\rm NN}}=200\,{\rm GeV}$. The numerical analysis is done in the perfect-fluid Bjorken-expanding resistive magnetohydrodynamic background and novel results are reported. In particular, we show that the electric field plays a significant role in the competition between expansion and dissipation.
