We determined the variation tendency of viscosity (η) at various solids load- ing (α) for 3Y-TZP suspension as a function of dispersant concentration (Cw) using vis- cosity measurement, measured the diameter of particles as a function of Cw in very dilute suspension using light scattering method, and obtained the surface features of the sedi- ment of suspension with different Cw using SEM. We also discussed the influence of the microstructure of adsorbed polymer layers on particles and their interactions in the dis- persing medium on the stability of suspension. Then two different stable states and two different unstable states for 3Y-TZP suspension were given. Accordingly, the (Cw, η), (Cw, α), and (α, η) two-parameter, and (Cw, α, η) three-parameter stability maps were con- structed. Based on the DLVO theory calculations, the dispersant concentration, particle distance (r), and interparticle potential energy (VT) maps with various solids loading for 3Y-TZP aqueous suspension were also constructed. In (Cw, r) two-parameter coordinate system, the stable motion region map for particles was established. The Cw, α, and VT,max (the highest potential energy) surface of the potential barrier map was obtained through calculation and simulation on the basis of the surfaces of Cw, r, VT maps introduced above. The (Cw, α) two-parameter stability map was then obtained from the Cw, α, VT,max map. The results showed that this theoretical map can qualitatively prove the experimentally obtained results—the existence of different dispersed states of particles in suspension system and the variation tendency of suspension stability with changing each parame- ter—were reasonable.

明确串联风机调节依据,可有效提高通风排烟系统的通风效率。围绕该问题,依托缩尺寸过海地铁区间隧道通风试验平台,以串联通风机组为试验对象,确定了串联风机组的9种工况,测定了声压级、电功消耗和风量。通过噪声源频谱分析而发现,100~300 Hz的宽频噪声对通风机组噪声贡献大,近风井端风机和远风井端通风机对各阶谐波影响不同;基频出现叠加现象,并且该基频主要受近风井端通风机的影响。最终,基于噪声场反演,提出减噪降耗的调节方法,即近风井端通风机转速不低于远风井端通风机转速。

There is considerable potential for integrating transarterial chemoembolization(TACE),programmed death-(ligand)1(PD-[L]1)inhibitors,and molecular targeted treatments(MTT)in hepatocellular carcinoma(HCC).It is necessary to investigate the therapeutic efficacy and safety of TACE combined with PD-(L)1 inhibitors and MTT in real-world *** this nationwide,retrospective,cohort study,82. HCC patients receiving either TACE plus PD-(L)1 blockades and MTT(combination group,n=376)or TACE monotherapy(monotherapy group,n=450)were included from January 2.18 to May *** primary endpoint was progression-free survival(PFS)according to modified *** secondary outcomes included overall survival(OS),objective response rate(ORR),and *** performed propensity score matching approaches to reduce bias between two *** matching,2.8 pairs were included with a predominantly advanced disease *** PFS in combination group was 9.5 months(95%confidence interval[CI],8.4-11.0)versus 8.0 months(95%CI,6.6-9.5)(adjusted hazard ratio[HR],0.70,P=0.002..OS and ORR were also significantly higher in combination group(median OS,19.2.16.1-2..3]vs.15.7 months[13.0-2..2.;adjusted HR,0.63,P=0.001;ORR,60.1%vs.32.0%;P3/4 adverse events were observed at a rate of 15.8%and 7.5%in combination and monotherapy groups,*** results suggest that TACE plus PD-(L)1 blockades and MTT could significantly improve PFS,OS,and ORR versus TACE monotherapy for Chinese patients with predominantly advanced HCC in real-world practice,with an acceptable safety profile.

对近年来MOF材料去除水环境中重金属、有机物的相关研究进行了总结与评述.本篇是该主题的第2.,主要对MOF材料去除水中有机污染物的相关研究进行总结和论述.研究表明,MOF材料含有大量开放性金属位点、路易斯酸碱位以及官能团,因而对染料、抗生素、农药、持久性有机污染物等均具有较高的吸附性能.氢键、π-π作用、疏水作用和静电引力是其吸附有机污染物的主要机制,部分MOF材料中较大的孔道结构也有利于大分子有机污染物的吸附;另外,部分MOF材料还具有优异的催化性能,能够作为类Fenton催化,光催化以及过硫酸盐活化的催化剂实现对有机污染物的催化降解,其中光催化反应中污染物的降解主要源于·O2.、·OH和h+的贡献;而在过硫酸盐体系中,·O2.、·OH、SO4·-和1O2.导致有机污染物分解的主要活性氧化物种.基于对先前研究的回顾,相信未来的研究领域包括但不限于以下方面:(1)进一步提高MOF在去除有机污染物方面的性能,并提高其可回收性;(2.开展新型MOF催化材料的制备及催化反应机理的研究;(3)研究MOF缺陷结构的调控,以开发具有更高吸附和催化性能的新型MOF材料;(4)研究新的框架材料,例如共价有机骨架(COFs)材料,并将其应用于污染物净化领域.
