Correcto

• 研发团队在反复测试中发现，该新型材料的抗拉强度已接近当前冶金技术所能达到的理论极限，具有重大工程意义。(The R&D team found through repeated testing that the tensile strength of this new material is approaching the theoretical limit achievable with current metallurgical technology, which has significant engineering implications.)
• 优秀的运动员不仅要有强健的体魄，更要具备在身体极限状态下依然保持心理稳定和战术清晰的精神韧性。(Outstanding athletes need not only a strong physique but also the mental resilience to maintain psychological stability and tactical clarity even when their bodies are at their limits.)

Incorrecto

• 极限很低 — use 上限/下限 for specific bounds (upper/lower limit); 极限 implies the absolute maximum/minimum, not an adjustable threshold
