合理确定岩石材料强度参数是工程设计的关键问题之一。为有效描述岩石的强度特性,众多学者提出了大量三维强度准则,其中基于两参数偏函数的修正Hoek-Brown(H-B)准则取得了良好效果,能够有效地反映岩石的静水压力效应、Lode角效应及中间主应力效应等强度特性。确定修正H-B准则的等效Mohr-Coulomb(M-C)参数有利于提高其在工程应用中的便利性,因此提出一种基于I1-√J2平面计算三维强度准则瞬时等效M-C参数的方法,应用于修正H-B准则,并对计算方法的合理性及瞬时等效M-C参数与岩石强度特性的关系进行讨论。结果表明:瞬时等效M-C参数可有效表征非线性静水压力效应,且合理反映Lode角效应和中间主应力效应的区间性特点;瞬时等效M-C参数可有效表征静水压力对Lode角效应的影响和最小主应力对中间主应力效应的影响,静水压力增大时,Lode角效应更为明显,且当最小主应力增大时,瞬时等效内聚力反映出更为显著的中间主应力效应;该方法能够合理地计算瞬时等效M-C参数,修正H-B准则具有准确预测岩石强度的能力。上述成果对修正H-B准则在实际工程中的应用具有较强的指导意义。

In this study,a class of rare earth composite sandwich phthalocyanines(MPcs,M=La,Y,Yb,Sc) were prepared and compounded with graphene and carbon nanotubes to obtain MPc/Gr and MPc/CNTs *** electrocatalytic behaviors of MPc/Gr and MPc/CNTs electrodes were further *** results show that the central rare earth metal has a large influence on the electrocatalytic *** the MPcs/Gr samples,ScPc with the smallest ionic radius and molecular size can be more uniformly dispersed in graphene,and the hydrogen precipitation overpotential of ScPc/Gr electrode is514 mV,corresponding to a Tafel slope of 148 mV/dec,with better electrocatalytic performance than other rare earth metal *** for the MPc/CNTs composites,LaPc,which has the largest ionic radius and molecular size,is more uniformly dispersed on the surface of CNTs,so that the LaPc/CNT electrode exhibits the best LSV performance with the smallest corresponding Tafel slope(176 mV/dec).The main reason is the different binding modes of MPcs molecules in Gr and *** rare earth phthalocyanine is combined with layered graphene,the smallest size of rare earth phthalocyanine(ScPc)is more easily embedded in the graphene layer,resulting in better homogeneity of the composite,larger effective contact area and better electrocatalytic *** contrast,when rare earth phthalocyanine is bound to carbon nanotubes in a tubular structure,it is mainly bound by attaching to the surface or being entangled by the carbon *** this case,the rare-earth phthalocyanine molecules(LaPc)with larger layer spacing can provide more contact area with CNTs,forming a more uniform and effective composite,which eventually provides more active sites and better electrocatalytic performance.

The present study aimed to compare the nutritional effects of cholesterol, bile acids, and combination of cholesterol with bile acids in plant-based diets on juvenile genetically improved farmed tilapia(GIFT;Oreochromis niloticus). The isonitrogenous(321 g/kg crude protein) and isolipidic(76 g/kg crude fat) diets(Con diet) were based on plant protein sources, which included corn gluten meal, soybean meal, cottonseed meal and rapeseed meal. The Con diet was supplemented with 12 g/kg cholesterol(CHO diet), 0.2 g/kg bile acids(BAs diet), a combination of 12 g/kg cholesterol and 0.2 g/kg bile acids(CHO-BAs diet),respectively. Each diet was fed to three tanks in an indoor recirculating aquaculture system for 9 *** showed that compared to the Con group, fish had a higher weight gain rate, hepatosomatic index,and a lower feed conversion ratio in the CHO-BAs group. The highest levels of whole-fish fat and ash were found in the Con group. Serum parameters, including activities of alanine aminotransferase(ALT) and aspartate transaminase(AST), along with levels of glucose(GLU) and triglyceride(TG) except for total cholesterol(TCHO), were lower in the CHO, BAs, and CHO-BAs groups than those in the Con group(P riptional levels of bile acid metabolism-related genes(including fxr, fgf19, bsep) were up-regulated in the CHO-BAs group(P rine-conjugated bile acids(T-BAs), followed by free bile acids(Free-BAs) and glycine(G-BAs)were determined in tilapia bile.

The hard X-ray nanoprobe beamline BL13U is a phase-Ⅱ beamline project at the Shanghai Synchrotron Radiation *** beamline aims to enable comprehensive experiments at high spatial resolutions ranging from 50 to 10 nm. The X-ray energy range of the beamline, 5–25 keV, can detect most elements in the periodic table. Two operating modes were designed to accommodate the experimental requirements of high-energy resolution or high photon flux, respectively. X-ray nanofluorescence, nanodiffraction, and coherent diffraction imaging are developed as the main experimental techniques for BL13U. This paper describes the beamline optics, end station configurations, experimental methods under development, and preliminary test results. This comprehensive overview aims to provide a clear understanding of the beamline capabilities and potential applications.
