Electro-production of several pentaquark states is investigated in this study.The eSTARlight package is adapted to study the electro-production of J/ψ and (r)(1S) via pentaquark Pc and Pb resonance channels in ep → eJ/ψp and ep → e(r)(1S)p scattering processes at the proposed electron-ion colliders (EICs).The results obtained in this study are compared to those of non-resonance t-channels,which are described in the pomeron exchange model developed in our studies.Some pseudo-rapidity and rapidity distributions of J/ψ and (r)(1S) are presented for the proposed EICs,including EicC and EIC-US.It is found that EicC is a good platform to identify Pb states in the future.

为满足土工布材料高强度、高过滤性的生产要求,以聚丙烯长丝机织土工布为基材,聚丙烯纺黏针刺非织造土工布为面层,采用针刺复合工艺并调节针刺密度制备了一系列聚丙烯纺黏/机织复合土工布,系统探讨了针刺密度对聚丙烯纺黏/机织复合土工布力学和水力学性能的影响。分别采用压力过滤测试和落差脱水测试评估土工布对粉煤灰浆的脱水性能。结果表明:当针刺密度大于35刺/cm2时,复合土工布的纵/横向拉伸强度均表现出明显的下降;剥离强力和透水率随针刺密度的增大而增大,但选用的针刺密度对顶破强力和有效孔径(O98)没有明显影响。复合土
