单膛石灰竖窑的改造

我厂竖窑容积为250m^3，设计利用系数为0．85t/(m^3．d)。随烧结产量的不断增加，石灰产量已不能满足烧结生产的需要。为了提高石灰产量，进行了扩容改造，容积由原来250m^3增加到298m^3，并针对目前生产实际提出下一步改造设想。     

加油站油品用体积交接存在的问题及建议

叙述了目前加油站在实行按任意温度下的体积交接，由于未考虑油品体积随温度、压力、密度的变化，出现了零售损耗很大的问题。建议加油站在现阶段采用“准标准体积”交接；在由体积转换为质量计算加油站损溢时，使用油库当月发出的平均密度；当财会核销损溢时，不使用盘存的体积和固定密度进行计算的方法，而使用实际盘点的质量数，以真实反映加油站的当期损溢。

大型储罐基础非平面倾斜问题的探讨

大型储罐因基础产生非平面倾斜而影响其正常使用的情况在工程中时有发生,文章通过对某油罐工程中基础沉降观测结果的分析,探讨了储罐基础产生非平面倾斜的原因。相邻储罐之间的相互影响、充水预压未达到规范要求以及地基处理措施不当是引起储罐基础非平面倾斜的主要因素。针对相邻储罐间的相互影响,根据现行《石油化工企业设计防火规范》和《石油化工企业钢储罐地基与基础设计规范》的规定,提出以下建议:储罐布置的净距除应满足防火规范规定外,有条件时也应适当考虑对基础沉降的影响,当采用复合地基时,相邻储罐间的净距不宜小于0.6 D;当占地面积成为主要矛盾,储罐间的净距只能限制在防火规范规定的最小范围时,在地基处理时就应采取有效措施,以尽可能减少相邻储罐的相互影响。     

Density Measurement of Liquid Ni-Ta Alloys by a Modified Sessile Drop Method

The density of liquid Ni- Ta alloys was measured by using a modified sessile drop method. It is found that the density of the liquid Ni- Ta alloys decreases with the increasing temperature, but increases with the increase of tantalum concentration in the alloys. The molar volume of liquid Ni- Ta binary alloys increases with the increase of temperature ancl tantalum concentration.     

Operating experience from the ehecatl wind turbines

This paper presents a summary of the mechanical features and the medium term operating experience from three small horizontal axis wind energy conversion systems covering a range of 500 to 5000 Watt, intented for rural and isolated communities. These turbines have a new regulator which reduces gyroscopic loads, is easy to adjust and could be manufactured stronger and in smaller sizes than the conventional tail vanes. It is concluded that is feasible to build cheaps and reliable wind turbine generators with an acceptable efficiency employing common-use elements, but is needed a careful and optimized design.

Volumetric properties of mixtures of 1,4-dioxane and water at high pressures

Densities of aqueous of 1,4-dioxane have been measured at temperatures from 298 to 348 K and at pressures up to 40 MPa by a vibrating-tube method. Molar volumes obtained with an estimated uncertainty of ±0.2°,% are correlated with pressure by the Tait equation within the experimental uncertainty. Pressure and composition dependences of the excess molar volume, partial molar volume, and isothermal compressibility are determined and they are compared with those of other aqueous solutions.     

Edge detection,three-dimensional cell boundary reconstruction and volume and surface area estimation from differential interference contrast images

Three-dimensional (3-D) cell morphology is important for the understanding of cell function and can by quantified in terms of volume and surface area. Differential interference contrast (DIC, or Nomarski) imaging can enable cell edges to be clearly visualized in unstained tissue due to the slight difference in refractive index between aqueous media and cytoplasm. DIC is affected in only one direction - the direction of the optical shear. A 1-D edge detector was used in that direction with a scale length equal to that of an in-focus edge to highlight cell boundaries. By comparison with the signal from the edge detector on an out-of-focus slice, the in-focus slices could be segmented and, after noise suppression, cell outlines obtained. A voxel paradigm was used to calculate cell volume and differential geometry was used for surface area estimation. We applied this approach to obtain 3-D dimensional information by optical sectioning of motile Amoeba proteus.
