Irradiation of a thermonuclear capsule by a laser-induced X-ray pulse (indirect drive) is a way to maximally reduce the inhomogeneity of the capsule heating and, thereby, to minimize the negative influence of hydrodynamic instabilities on its compression. Nevertheless, the application of this method in the world’s largest NIF facility with a laser pulse energy of about 1.8 MJ at the Lawrence Livermore National Laboratory (LLNL), USA has not yet provided the ignition of indirect-drive thermonuclear capsule – obtaining of the deuterium–tritium reaction energy equal to the spent laser energy. We devote this paper to the theoretical study of compression and burning of thermonuclear capsule with different degrees of violation of its heating uniformity by laser-induced X-ray pulse within the framework of further development of the indirect-drive approach.

通过激光诱导的X射线脉冲（间接驱动）辐照热核胶囊是最大程度地降低胶囊加热的不均匀性，从而最大程度地减小流体动力不稳定性对其压缩的负面影响的一种方式。尽管如此，该方法在美国劳伦斯·利弗莫尔国家实验室（LLNL）的激光脉冲能量约为1.8 MJ的世界上最大的NIF设施中的应用尚未提供间接驱动的热核胶囊的点火-获得氘tri反应能量等于消耗的激光能量。
