The bulk superconducting properties of polycrystalline TaRh₂B₂ under pressure are investigated with transport resistivity [ρ(T)], and dc magnetization [M(T) and M(H)] measurements up to ~3 GPa, and 1 GPa respectively. The application of hydrostatic pressure leads to a decrease in T_c for both magnetic [dT_c/dP is −0.4 K/GPa (0 ≤ P ≤ 1 GPa)] and transport [(dT_c/dP) is −0.02 K/GPa (0 ≤ P ≤ 1 GPa) and −0.06 K/GPa (1 ≤ P ≤ 2.5 GPa)] measurements. At 2.5 GPa the upper critical field, μ₀H_c2(0), and the irreversible field, μ₀H_irr(0), are found to be (11.8 ± 0.2) T and (6.5 ± 0.1) T respectively. The critical current density, J_c (at μ₀H = 0 T), decreases from 6.5 × 10⁵ A/cm² (0 GPa) to 2.5 × 10⁵ A/cm² (0.9 GPa) at 4.3 K. The flux pinning and J_c(H) in TaRh₂B₂ are significantly affected by the application of external pressure. It is seen that surface and volume flux pinning coexist both at ambient pressure and at high pressure. We infer that the pinning energy and superconducting properties are suppressed by external pressure.

用传输电阻率[ ρ（T）]和dc磁化强度[ M（T）和M（H）]分别测量了多晶TaRh ₂ B ₂在压力下的体超导性能，测量值分别约为3 GPa和1 GPa。静水压力引线以降低应用Ť _Ç两个磁性[的dT _ç / DP是-0.4 K / GPA（0≤  P  ≤为1GPa）]和运输[（的dT _ç / DP）为-0.02 K / GPA （0≤  P  ≤为1GPa）和-0.06 K / GPA（1个≤  P ≤2.5 GPa）]测量。在2.5GPa以上的上临界磁场，μ ₀ ħ _C2（0），和不可逆场，μ ₀ ħ _IRR（0），被发现是（11.8±0.2）T和分别（6.5±0.1）笔。临界电流密度，Ĵ _Ç（在μ ₀ ħ = 0 T），从6.5×10降低⁵  A /厘米²（0 GPa）的2.5×10 ⁵  A /厘米²在4.3 K.通量（0.9 GPa）的在TaRh ₂ B _2中钉扎和J _c （H）受外部压力的影响很大。可以看出，表面通量和体积通量钉扎在环境压力和高压下共存。我们推断，钉扎能量和超导性能受到外部压力的抑制。
