Applications of Enzyme-simulating Copper Complex Catalyst in Low-temperature Scouring/Bleaching of Cotton Knits

An enzyme-stimulating catalyst( PTL) with copper ions( Cu~(2+)) as the activation center and aminophosphonate as ligand was developed and applied in low-temperature scouring/bleaching of cotton knits. The optimal weight ratio of Cu~(2+) to aminophosphonate was 1 ∶75. Via orthodox and single-factor experiments,the most efficient formula for low-temperature scouring/bleaching was composed of 0. 4 g/L high-efficiency degreaser DM-1130,1. 5 g/L PTL,2. 0 g/L sodium hydroxide( NaOH),and 7. 0 g/L 30% hydrogen peroxide( H_2O_2). The PTL could not only increase the whiteness of cotton knits,but also remove pectin to enhance capillary effect.

太浦河泵站斜15°轴伸泵水力动态力分析

太浦河泵站选用的斜15°轴伸式轴流泵(以下简称斜15°轴伸泵)，为特低扬程、大流量的水泵.它具有叶轮直径大、水泵装置流态复杂、水泵轴承受力大等特点.为此，针对太浦河泵站斜15°轴伸泵，进行了水泵装置从吸入口至出口包括叶片、导叶、弯管段等在内的整体三维粘性流动分析，得到了流道内部不同工况下的流动特性如压力、速度分布规律及泵特性曲线，以及流道内部的旋涡分布和水力损失情况.同时进行了导叶和叶轮流动动静干涉引起的三维不稳定流动分析，得到了叶轮在不同工况下受到的轴向水推力及径向水推力在旋转过程中的变化规律，从而为轴承设计提供了比较准确的受力条件.该项研究对其他斜式泵的内部流态及受力分析也是一个很好的借鉴.

Effect of Incident Intensity on Films Growth in Pulsed Laser Deposition

Incident intensity, defined by the amount of particles deposited per pulse, is an important parameter in the film growth process of pulsed laser deposition （PLD）. Different from previous models, we investigate the irreversible and reversible growth processes by using a kinetic Monte Carlo method and find that island density and film morphology strongly depend on pulse intensity. At higher pulse intensities, lots of adatoms instantaneously diffuse on the substrate surface, and then nucleation easily occurs between the moving adatoms resulting in more smaller-size islands. In contrast, at the lower pulse intensities, nucleation event occurs preferentially between the single adatom and existing islands rather than forming new islands, and therefore the average island size becomes larger in this case. Additionally, our results show that substrate temperature plays an important role in film growth. In particular, it can determine the films shape and weaken the effect of pulse intensity on film growth at the lower temperatures by controlling the mobility rate of atoms. Our results can match the related theoretical and experimental results.
