The kinetics of internal chlorination of Ni-Cr-Ce alloy in chlorine at 575℃ has been *** chlorination of Ni-Cr-Ce alloy occurred to formation of CrCl_(2) and CeCl_(3) solid precipi-tates which is thermodynamically stable and has lower vapor pressure at the temperature along grain *** initial corrosion stage,the internal chlorination rate nearly followed parabolic rate law,the internal chlorination was accompanied by the consumption of the alloy by volatilization corrosion which obeyed a linear rate equation,the thickness of the internal chlorination region would be governed by a paralinear rate *** a sufficiently long period of corrosion,the rate of internal chlorina-tion would be equal to the rate of overall metal consumption,the depth of internal chlorination approaches a steady state *** of Ce to Ni-Cr alloy increased the degree of internal chlorination.

目的:探究温通刮痧在神经外科尿潴留患者中的临床疗效。方法:选取2023年2月—2023年12月在佛山市中医院住院的60例需留置尿管患者作为研究对象,采用随机数表法分为对照组和研究组,每组各30例。研究组在尿管插管导尿后予以温通刮痧治疗基础上拔出导尿管,对照组尿管插管导尿后直接拔除导尿管,两组尿管留置时间均≤14 d。比较两组患者治疗后临床疗效、排尿情况(拔管后首次排尿时间、拔管后12 h排尿次数与均次尿量),比较治疗前后中医证候评分、排尿症状量表(USS)评分,比较治疗后尿潴留复发情况(3 d内尿潴留发生率、重置导管率),比较治疗前后两组生活质量[脑卒中专用生活质量量表(SS-QOL)]评分情况。结果:治疗后,研究组患者临床疗效显著高于对照组,差异有统计学意义(P<0.05);研究组首次排尿时间较对照组提前且拔管后12 h内排尿次数、排尿量均高于对照组,差异有统计学意义(P<0.05);两组中医证候评分、USS评分均显著降低,且低于同一时间对照组,差异有统计学意义(P<0.05);研究组3 d内尿潴留发生率、重置导管率均低于对照组,差异有统计学意义(P<0.05);两组SS-QOL评分较治疗前有显著升高,且研究组显著高于同一时间对照组,差异有统计学意义(P<0.05)。结论:温通刮痧在神经外科尿潴留患者中能取得良好疗效,有助于改善患者排尿情况、避免尿潴留复发,对缓解临床症状、提高患者生活质量有积极意义。

The powder mixture of Al, Ti and graphite has been mechanically alloyed in a planetary ball *** structural evolution of as-milled powder sample has been characterized by XRD, DTA. The results show that the amorphous phase is formed first at an early milling stage, then crystallization occurs during further milling, leading to formation of a nanocrystalline fcc metastable phase. In contrast, during annealing the amorphous phase is crystallized to the equilibrium phase instead of the fcc phase. This indicates that crystallization during ball milling is different from that induced by annealing

It is demonstrated that a low grade, silver containing manganese deposit can be exploited by reaction with a ZnS concentrate. In the process, Mn(IV) is reduced to Mn(II) and the ZnS converted to ZnSO4. In the process, Mn and Zn are solubilized. By studying the effects of quantity of reducing agent and sulfuric acid added and of time, temperature and liquid-to-solid ratio on the leaching process, the optimum technological conditions have been achieved under which the amount of manganese leached was 98 %. The silver can be removed from remaining solids by adding ammonia liquor. Then by adding hydrazine hydrate, sponge silver with purity up to 99 % can be obtained with a recovery of 87 %.
