提出了一种水平注入球形激光聚变能靶在充满残余气体的反应堆中轨迹的计算方法。为了评估气体阻力和沿喷射路径设置的位置测量单元（PMU）的放置误差，连续进行两次测试喷射，并通过 PMU 测量飞行中的目标位置。两个未知的系统参数，气体阻力和放置误差，通过求解方程组来确定。确定系统参数后，利用飞行中注入目标的时间数据和位置数据，通过简单算术即可计算出新注入聚变目标到达反应堆中心的位置和到达时间。
A calculation method is presented for the trajectory of a horizontally injected spherical laser fusion energy target in a reactor filled with residual gas. To evaluate the gas resistance and the placement error of the position measurement unit (PMU) set along the injection path, a test injection is successively made two times and the target positions in flight are measured by PMUs. Two unknown system parameters, gas resistance and placement error, are determined by solving an equation system. After determining the system parameters, the arrival position and arrival time of the newly injected fusion target at the reactor center can be calculated by simple arithmetic with the time data and position data of the injected target in flight.
