多雾条件下边坡雷达在露天矿山边坡监测中的应用研究

针对南方多雾等恶劣条件下露天矿山边坡监测困难等问题,本文以边坡雷达为监测手段,选取遂川县坚基矿业车元坳矿区为研究对象,对该矿露天采场边坡进行非接触式不间断监测,结合车元坳矿区边坡雷达2023年11月9日—2023年12月8日的监测数据,通过对数据异常区域与矿山实际现场勘查进行对比分析。研究结果表明：根据11月09日—11月14日变形数据,局部区域变形量剧增,经现场人工巡检并采取治理措施,表明边坡雷达在露天矿山边坡监测作用有效,监测数据是可靠的;边坡雷达在多雾条件下仍能维持其监测性能。研究结果可为南方其他露天矿山边坡选取监测手段提供一定的参考。

Social-cognitive determinants of hoist usage among health care workers.

Injuries caused by unsafe manual handling of patients are a major source of ill health in health care workers. The present study evaluated the ability of 4 classes of variable to predict use of a hoist when moving a heavily dependent patient. Variables examined were occupational role characteristics, such as hours of work and type of shift worked; biographics, including age and height; aspects of occupational context, such as number of hoists available and number of patients; and motivational variables specified by the theory of planned behavior (Ajzen, 1985) and protection motivation theory (Rogers, 1983). Regression analyses showed that background and social-cognitive variables were able to account for 59% of variance in intention to use a hoist and 41% of variance in use of the hoist assessed 6 weeks later. Height, hoist availability, coworker injunctive norm, perceived behavioral control, response cost, response benefits, and social and physical costs of not using the hoist each explained independent variance in motivation to use a hoist at work.

Group manual dexterity in women.

To determine the extent to which group performance could be predicted from knowledge of the performance of the group's members, 60 pairs of university women were first given six individual trials on a modified Purdue Pegboard task, and then six trials in which the members of the pair worked together. For each pair, the 'high' and 'low' scorer (on the individual trials) was identified, and correlations were calculated between the 'high' score, the 'low' score, the difference score, and the score for the pair on the second set of trials. These results are compared with previous results from men students. "The most important fact which emerges… is that a surprisingly small proportion of the total variance on the group-performance task can be predicted… [from the individual-performance scores]… " (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

手弧焊规范对酸性介质中12X18H10T钢焊接接头腐蚀破坏的影响

介绍了俄罗斯学者关于手弧焊不同规范对在酸性介质中工作的12X18H10T不锈钢焊接接头腐蚀破坏影响的研究概况。结果表明：酸性工作介质会促使耐蚀稳定性较好的12X18H10T不锈钢的焊接接头出现晶间腐蚀（MKK）,腐蚀程度的大小受多种因素影响,其中焊缝组织晶粒尺寸越小腐蚀程度越轻;采用脉冲电流手弧焊比采用直流电流手弧焊的焊接接头组织晶粒小。因此,采用脉冲电流手弧焊可以提高不锈钢焊接接头的耐腐蚀稳定性。     

基于不同人体测量方法的数据一致性和可替换性研究

为探究人体测量中三维数据与手工数据间的一致性和可替换性,及不同扫描仪所得结果间的数据等价性,利用HumanSolutions和[TC]² 2种三维扫描仪分别对20~35周岁的女性样本人体进行扫描,通过逆向工程软件手动测量388个样本的30项身体特征尺寸。对比2组三维数据与其对应手工数据的折线图,利用组内相关系数对数据的一致性进行探究;依据国标对三维数据与手工数据间的可替换性进行讨论和判别;以手工数据为媒介,对比2种三维数据与真实值间的一致性和可替换性,判断不同扫描仪数据结果的等价性。结果表明:2种仪器所得数据与手工数据间存在较好的一致性,组内相关系数大于0.75,3种数据在部分测量项上具有较好的可替换性,进行数据处理和分析时可等价使用。
