安全玻璃中气泡的自动检测研究

耐环境性试验是安全玻璃强制检验的内容之一。经过耐环境性试验后的安全玻璃产品中气泡的检测和识别是判定产品是否合格的重要依据。根据玻璃气泡图像的特点，提出了一种安全玻璃气泡的自动检测算法。首先采用基于数学形态学的方法对原图像进行了目标增强;然后进行图像分割;采用孔洞填充和数学形态学法进行修正;最后进行特征提取，获得玻璃气泡的边缘信息。实验结果显示，该算法能准确的检测出安全玻璃中的气泡，具有一定的应用价值。     

Simulation of industrial man-machine systems

In the design of large industrial processes, ergonomics designers can benefit from the use of computer simulation of man/machine systems when on-site studies are too risky or costly and laboratory studies alone have questionable generalization. This paper provides an illustration of this methodology for a hot strip mill in the steel industry and a demonstration of ergonomic design applications. A special simulation package which was developed for small military systems was adapted to this large industrial case and applied to an older manually-controlled mill of the 1930s. The simulation model was then modified to reflect automation and manning changes found in the mills built in the 1950s and the simulation results verified the actual performance differences between these mills. Experiments in further design and manning changes were made in order to demonstrate the usefulness of simulation as a design-aiding technique.     

解读玻璃装饰壁画艺术的功能性语言

20世纪前半期德国文学家瓦尔特·本雅明在其"于使用中接受"的观点中,简明地道出了艺术与大众的关系。玻璃装饰壁画作为一种与空间环境紧密相连的装饰形态,功能性语言是其非常重要的一个方面。艺术家在创作的过程中如何把艺术性与功能性紧密相结合,并最终实现在自己的作品中,将反应一件作品在空间中的生存状态。     

APPLICATION OF RECONSTRUCTION ANALYSIS IN SOLVING THE PROBLEM OF FLOAT GLASS STAINED WITH TIN

In float glass manufacturing, the glass is often stained with tin, which will result in deficient quality. The amount of stained tin is related to five factors: temperature, oxygen content in tin liqnid, bath pressure, total amount of protecting gas, and the thickness of the glass. On the basis of the experimental data, and through system reconstruction analysis, each factor's value range where there is not any tin stain on the float glass is found.

Nucleation and growth of potassium dihydrogen phosphate crystals in silica gels

Kinetic studies on nucleation and growth of potassium dihydrogen phosphate crystals in silica gels show that the rate-determining process for the growth of these crystals in silica gels is diffusion. Morphology, microhardness and perfection of gel grown crystals are also reported.     

31P N.m.r. studies of the hydrolysis of added phosphates in chicken meat

The hydrolysis of tripolyphosphate and pyrophosphate in comminuted chicken muscle was examined quantitatively by ³¹P n.m.r. Ageing the muscle before addition of phosphates resulted in a similar change of the hydrolysis rate of both species. By contrast addition of sodium chloride caused very rapid hydrolysis of tripolyphosphate and slowing of the hydrolysis of pyrophosphate. Untreated muscle showed very low levels of phosphocreatine immediately after death and complete loss of ATP within one hour.     

Thermal expansion studies on As-Sb-Se glasses

The results of measurement of thermal expansion coefficient from 50°C to the softening temperature on eight glass compositions of the As-Sb-Se system are presented. Measurements have been made on (As, Sb)₄₀Se₆₀ and As _x Sb₁₅Se_85−x glasses at heating rates of 1°C/min and 5°C/min. The composition and temperature dependence of the thermal expansion coefficient is discussed in the light of results of other chalcogenide glasses.     

High speed scanning calorimetry for amorphous alloys

A high speed scanning calorimeter has been developed for simultaneous measurements of heat capacity and electrical resistivity of thin strips. The system was designed for amorphous alloys but can be used for other materials as well. The specimen is heated by an electrical current at rates ranging from 250 to 40,000 K·s^–1, and the temperature is sensed by an IR pyrometer ranging down to room temperature. The maximum data acquisition rate is 50 kHz. Operational characteristics of the system are given, and various phenomena that affect design and operation are discussed. Data are taken for some Metglas alloys. Glass transition and crystallization temperatures as well as rough viscosity data are evaluated. At high heating rates the glass transition is spread over a wide temperature range. The formation of metastable crystalline phases can be bypassed so that stable phases form directly from the amorphous state.
