The protection of quantum entanglement has always been the focus of researchers. We adopt the scheme of combining weak measurement and measurement reversal to explore the protection effect of two-qutrit system in four noise channels, i.e., the amplitude damping channel, the phase damping channel, the bit flip channel and the depolarizing channel. For the given qutrits state with \(\alpha =\beta =\gamma =\frac {1}{\sqrt {3}}\), it is found that the protection scheme can help to protect entanglement in the amplitude damping channel, while for the state with \(\alpha =\beta =\frac {1}{\sqrt {2}},\gamma =0\), the protection scheme plays a protective role in the amplitude damping channel and the depolarizing channel. We also calculate and discuss how the negativity and the probability of success behave when adjusting the weak measurement or measurement reversal strength. In different noise channels, the entanglement can be kept as much as possible by choosing the appropriate weak measurement parameters. It provides a strong basis for the system to maintain maximum entanglement in different noise channels.

量子纠缠的保护一直是研究人员关注的焦点。我们采用弱测量和测量反演相结合的方案，探讨了双量子系统在幅度阻尼通道、相位阻尼通道、位翻转通道和去极化通道四个噪声通道中的保护效果。对于具有\(\alpha =\beta =\gamma =\frac {1}{\sqrt {3}}\)的给定 qutrits 状态，发现保护方案可以帮助保护振幅阻尼通道中的纠缠，而对于具有\(\alpha =\beta =\frac {1}{\sqrt {2}},\gamma =0\) 的状态，保护方案对振幅阻尼通道和去极化通道起到保护作用。我们还计算和讨论了在调整弱测量或测量反转强度时负性和成功概率的表现。在不同的噪声通道中，可以通过选择合适的弱测量参数来尽可能地保持纠缠。它为系统在不同噪声通道中保持最大纠缠提供了强有力的基础。
