新型燃气地下引入管的开发和利用

当气源由人工煤气转换为天然气后，地下铸铁管道与地上立管连接处的腐蚀问题更加突出，该文介绍了一种新型燃气地下引入管及其使用效果。     

Construction of Youden hyperrectangles

Youden hyperrectangles are higher-dimensional generalizations of balanced block designs and generalized Youden designs. This kind of design has been shown to be optimal for the elimination of multi-way heterogeneity. In this paper, patchwork and geometric methods are combined to construct Youden hyperrectangles for many parameter values.     

添加沼液养猪的试验研究

沼液喂猪试验表明:添加沼液具有增加食欲、加快生长速度、缩短肥育期、提高饲料利用率(24.4％)、节省饲料,降低养猪成本(24.5％)的优点,在广大农村粗放的饲养管理条件下,沼液喂猪具有较大的推广价值。     

宁波历史文化转型探赜──兼论现实文化建设的方向

文化转型是一个客观的社会实际，也是文化发展演进的历史性标志。在宁波历史上，曾经出现过两次具有鲜明特色的文化转型期，其中，第一次转型发生在我国古代，南宋初年为关键的定型阶段，此次转型的结果是使宁波地区的文化形态由“未开化”走向“精致化”；第二次转型发生在我国近现代，民国年间为关键的定型阶段，此次转型的结果则使宁波地区的文化形态由“精致化”走向“世俗化”。种种迹象表明，当前正处于新一轮文化转型的关口，由“世俗化”迈进“现代化”应成为现实文化建设的方向。     

自动机泛函ORANPIA—函数程序设计的自动机策略思想

本文明确地提出“将自动机这一概念重新引入到作用式语言中来”。在作用式语言FFP中,为自动机的介入无需设置新的语言成分,而仅仅在FFP语言自身这一级上定义一个新的自动机泛函(名为Oranpia),就可使FFP语言赋有自动机式程序设计风格。此风格有利于我们在不少的实用场合采取“自动机策略思想”来自然地进行有效的程序设计。

A comparison of self-perceived physical and psycho-social worker profiles of people with direct work injury, chronic low back pain, and cumulative trauma

This study investigated the psycho-social factors among injured workers and the influence of their psycho-social profile on the readiness of return to work. Sixty-four subjects with injuries on the upper limbs or lower limbs, low back pain, or cumulative trauma disorder were recruited. The workers' profiles (self-perceived physical health, mental health, and work readiness) together with the impact and types of work injury on the workers' perceived wellness were measured. The regression model of work readiness was constructed to develop a theoretical background for predicting work readiness based on different factors. The results showed that injured workers with chronic injury such as low back pain or cumulative trauma had poorer self-perception of physical health and psycho-social/mental health compared to those with direct trauma. The regression analysis further affirmed that self-perceived pain and physical functioning were significant factors influencing the readiness for returning to work. Workers with low back pain were found to have lower motivation for returning to work. Other factors such as the non-verbal intelligence of the injured workers, their anxiety level, and the support they received from family members were found to have some indirect impact on their ability to return to work, but this was not statistically proven.
