禅宗解脱:宗教经验的审美化

禅宗解脱的实质是生命的自由。通过明心见性、转迷入悟的途径,心灵摆脱烦恼业障,进入无我境界,从而体验到一种想象的自由。这一过程在很多方面类似审美活动,在体验上具有审美自由的特征。但禅宗的解脱,以及解脱所达到的审美的人生境界之可能,其关键在于生命主体的自我消解。无我的或曰没有主体的自由,并不是一种真正的自由。因而,禅宗关于人的解放的理论和实践,其价值仅仅在宗教方面和美学方面。     

当前水价改革中迫切需要注意的问题

加强水价改革，提高水价，促进节约用水，已经成为全社会关注的焦点。在节约用水和水资源优化配置条件下如何确定水价，水价构成及供水企业的合理成本与利润，以及资源水价的分配和用途是当前水价改革中亟须研究探讨和重视的问题。商品水价应该包括三个部分：一是资源水价，二是工程水价，三是环境水价。只有包括资源因素的水价，才能真正发挥水价在水资源的优化配置和合理利用方面的调节作用。

省煤器管开裂原因分析

对省煤器开裂管进行了化学成分及宏、微观分析。分析结果表明，在高温高压条件下，在其焊缝溶合区出现粗大的魏氏组织，管材中的珠光体组织产生了不同程度的球化，而母材组织又存在严重的带状组织。在过热条件下熔合区极易出现裂纹，并由此快速扩展，造成省煤器管开裂。     

Development of a Magnetic Suspension Densimeter and Measurement of the Density of Toluene

The development of a magnetic suspension densimeter that has been built for measurement of the density of compressed liquid at pressures up to 30 MPa in the temperature range 20 to 150°C is described. The densimeter was first built by the author and his coworkers at NIST. We describe here further improvements made on a second system built at NMIJ based on the same principle. The densimeter uses a small coil suspended from an electronic balance. Within the coil is placed a sample cell in which the pressurized sample and a buoy, which is a permanent magnet, are enclosed. For measurement of density, balance readings are recorded (1) with the buoy at rest and (2) with the buoy in magnetic suspension. The measurement procedure is basically a hydrostatic weighing, which is simpler than those of conventional magnetic densimetry. As an example, measurements of toluene density performed as part of an inter-laboratory comparison are presented. The data agreed with reliable literature values to within a few hundredths of a per cent.     

Determination of instantaneous corrosion rates and runoff rates of copper from naturally patinated copper during continuous rain events

Instantaneous corrosion rates of naturally patinated copper of varying age (16 months, 138 and 145 years) have been determined during continuous rain events in the laboratory with electrochemical impedance spectroscopy using a two-electrode cell. The two-electrode cell was found to yield the same information in bulk rainwater as a conventional three-electrode cell.Relatively constant corrosion rates, between 0.2 and 0.6 μm/y, were determined for samples having a two-layer structure with an inner brownish layer of cuprous oxide and an outer greenish layer of basic copper salts (138, 145 years). Samples with cuprous oxide as the dominating phase of the patina (16 months) showed higher and somewhat increasing corrosion rates during a rain event (from 0.6 to 1.2 μm/y). During a continuous rain event, corrosion rates were found to be approximately 10 (brownish patina) and 25 times (greenish patina) lower than corresponding instantaneous runoff rates. The first flush phenomena of the runoff process, with an increased concentration during first flush and a relatively constant concentration during steady state, was indirectly seen as an increase in solution conductivity during the first rain volume followed by relative constant value. The contribution of the concentration in the first flush to the total annual runoff rate was significant for panels having a greenish layer (138, 145 years) whereas it was negligible for panels having a brownish layer (16 months).     

提高曲面近似展开精度的方法与实现

通过对不可展曲面近似展开精度的研究，提出了根据曲面曲率的大小对曲面自动进行网格划分，通过对综合展开误差数据场进行数据拟合来选取最优展开基点，基于空间曲面与其展开图间近似的等距变换关系进行展开样形的误差矫正等3种方法，这几种方法的实现在不同程度上有效地减小了曲面的近似展开误差，提高了曲面的近似展开精度。
