中文摘要：

为研究超高速弹丸碰撞靶板产生等离子体诱生的磁场，引用已有关于激光产生等离子体的磁场理论，结合麦克斯韦方程和法拉第电磁感应定律得到了超高速碰撞产生等离子体诱生磁场的1维理论模型。基于已有关于超高速正碰撞产生半球状等离子体云诱生磁场的偏微分方程，建立了柱坐标系下超高速斜碰撞产生部分椭球状等离子体云的偏微分方程。通过感应线圈进行了磁感应强度的实验测量，实验结果与模型预言表明，该模型可近似地描述超高速斜碰撞产生等离子体诱生的磁感应强度。

英文摘要：

One-dimensional theoretical models are obtained for magnetic fields of plasma induced by hypervelocity projectile impacting target, according to existing theories of magnetic fields about laser plasma along with the maxwell＇s equation and Faraday＇s law of electromagnetic induction. Meanwhile, Based on the partial differential equations of magnetic fields for semi-sphere plasma cloud generated by hypervelocity normal impact, the partial differential equations of magnetic fields are established for plasma cloud in the form of part of ellipsoid induced by hypervelocity oblique impact in cylindrical coordinate system. Magnetic induction intensity measurement is carried out with magnetic coils through hypervelocity impact experiment. Experimental results and model prediction show that the model can be used to describe the magnetic induction intensity induced by plasma during hypervelocity oblique impact approximately.
