The design of Bio-clean operating room in modern hospital is quite different from that of traditional operating room. This paper discusses three aspects of Bio-clean operating room design: air clean standard and air purification, interior equipment system and interior finish. It is hoped that this discussion will conduce to later designs. 相似文献

Additives, such as sodium perborate and borax, were examined in dialdehyde wrinkle resistant finishing of cotton. Results
indicated that the whiteness index (WI) of cotton treated with dialdehyde and additive showed about 90% of WI of the untreated
cotton but with decrease in wrinkle recovery angle (WRA) due to inhibition effect of these additives. Effect of additive on
the WRA reduction was more prominent with glutaraldehyde than with glyoxal. Reduction in WRA of cotton treated with both dialdehydes
and boron compound was minimized by simultaneous addition of formic acid in the bath. Addition of formic acid was also generally
beneficial in maintaining WI retentions after 8 months storage. Furthermore, boron compounds were also effective in improving
retentions of mechanical properties. By FTIR analysis the residual aldehyde group was detected on the dialdehyde-finished
cotton, whereas no peak was shown by addition of boron compounds. This suggested that the residual aldehyde group was a main
cause of fabric yellowing on the dialdehyde-finished cotton. Dialdehyde with boron compound, therefore, can be used to replace
a conventional formaldehyde-containing wrinkle resistant finishing of cotton. 相似文献

农业机械制造技术与一般机械制造技术相比,具有特殊性。如今大多数农机企业的技术跟不上先进机械制造技术的发展,农业机械制造技术比较落后。为此,将动态神经网络和模糊逻辑技术应用在农业机械加工制造中,能够很好地预测和控制工件的尺寸与形状,大大提高了加工精度。为此,以农业机械的轴类零件为例,建立了纵向磨削的Elman动态神经网络尺寸预测模型,采用论域自调整策略和模糊自适应控制理论,建立了纵向磨削的自适应控制模型,选择工作台的进给速度作为控制变量。仿真和实验结果表明,所建立的神经网络尺寸预测模型和模糊自适应控制模型是正确的。 相似文献

The purpose of the research was to examine the effect of three different levels of enzyme treatment on the physical characteristics
and the end-use suitability of the lyocell fabrics made with four different types of commercial wood pulp. The appropriate
enzyme concentration for obtaining an optimum as well as consistent physical characteristics and fabric hand trait was 3 g/l for the concentration levels tested in the present investigation. Weight loss was more affected by higher enzyme concentration
than other physical properties. H2 was least affected by enzyme treatment for all three physical properties and fabric hand.
5 g/l concentration exhibited little difference from 3 g/l in the physical characteristics, whereas the KES-FB values indicated a significant loss of fabric hand in most PHVs with
the 5 g/l concentration level. Among different garment parameters, all four fabric types were relatively inappropriate for the men’s
slacks (MS) fabric due to the lower hand value of koshi required by the MS parameter. However, despite the relatively low
koshi values, high fukurami values required for men’s dress shirt (MWDS) resulted in the highest THV among the four garment
parmeters. The four fabric types, which represent the usage of four different wood pulps, in general seem to exhibit a higher
applicability to women’s winter thin dress (WWTD) than women’s winter suit (WWS) garment parameter. 相似文献

丝素/柠檬酸防皱整理棉织物的初步研究 总被引：2，自引：0，他引：2
从pH值影响整理效果出发,分析用丝素、柠檬酸、丝素/柠檬酸复配分别整理棉织物后,对棉织物白度、撕破强力、折皱回复角的影响程度.结果表明:复配比单一整理剂的整理的效果好,丝素与柠檬酸有良好的协同增效作用,两者复配可改善棉织物的抗皱性,且白度、强力保留率及手感等均可达到满意效果. 相似文献

为探索新的蛋白饲料资源,我们用磷酸脲在春季对西门塔尔杂交肉牛进行了为期60 d的短期育肥试验。结果:60 d增重对照Ⅰ组61.3 kg,试验Ⅰ组66.1 kg,试验Ⅱ组68.5 kg。试验Ⅰ组和试验Ⅱ组的增重比对照Ⅰ组分别提高7.83%和11.75%,差异均不显著。对照II组60 d增重为76.4 kg,比试验Ⅱ组的高11.53%,表明在春季优质青草充足,能量饲料有保障的条件下,无论是在补充料为不含蛋白原料的纯玉米的条件下补饲非蛋白氮,还是在补充料为配合料的条件下补饲非蛋白氮,对杂交肉牛增重的影响不大。 相似文献

Summary Achieving optimal colour and texture in French fries requires careful control of the unit operations that convert the raw
potatoes into fries. The effects of variation in blanching, drying and finish frying conditions on puncture properties (peak
force and peak deformation) and Hunterlab L (lightness) values of French fries were investigated. Fries blanched by low-temperature
long-time (LTLT) conditions had larger peak force, peak deformation and L value than fries processed by standard conditions.
High-temperature short-time (HTST) blanching increased lightness but decreased peak force and peak deformation. For drying,
the colour and textural quality of French fries processed by standard conditions were better than those processed by the drying
alternatives. For finish frying, LTLT conditions increased peak force whereas HTST conditions increased lightness. Therefore,
a compromise has to be made in processing conditions to optimise both colour and textural quality. Even after finish frying,
compositional differences within potato tubers influenced texture, both between and within French fries. 相似文献
