The discovery of charge- and spin-density-wave (CDW/SDW) orders in superconducting cuprates has altered our perspective on the nature of high-temperature superconductivity (SC). However, it has proven difficult to fully elucidate the relationship between the density wave orders and SC. Here, using resonant soft X-ray scattering, we study the archetypal cuprate La_2-xSr_xCuO₄ (LSCO) over a broad doping range. We reveal the existence of two types of CDW orders in LSCO, namely CDW stripe order and CDW short-range order (SRO). While the CDW-SRO is suppressed by SC, it is partially transformed into the CDW stripe order with developing SDW stripe order near the superconducting T_c. These findings indicate that the stripe orders and SC are inhomogeneously distributed in the superconducting CuO₂ planes of LSCO. This further suggests a new perspective on the putative pair-density-wave order that coexists with SC, SDW, and CDW orders.

在超导铜酸盐中发现电荷和自旋密度波（CDW / SDW）阶数已经改变了我们对高温超导性（SC）性质的看法。但是，已经证明很难完全阐明密度波阶和SC之间的关系。在这里，使用共振软X射线散射，我们研究了宽掺杂范围内的原型铜酸盐La _{2- x} Sr _x CuO ₄（LSCO）。我们揭示了LSCO中CDW订单的两种类型，即CDW条带订单和CDW短程订单（SRO）。当CDW-SRO被SC抑制时，它会在超导T _c附近发展为SDW条带顺序，从而部分转变为CDW条带顺序。。这些发现表明，条纹序和SC在LSCO的超导CuO ₂平面中不均匀地分布。这进一步暗示了与SC，SDW和CDW指令共存的对偶密度波阶的新观点。
