论设计与概念的关系

“设计是一种创造性活动”是人们给设计的定义，但这只是一个抽象的说法。设计活动包括思维、图形的表现，模型或样板的制作等。在这个过程中，图形的表现本身是创造性的吗？尺寸的标注是创造性的吗？模型的制造是创造性的吗？毫无疑问这些都不是创造性的。显然，设计是一种创造性活动指的是设计的思维活动，其它的活动只不过是表现或表达思维结果的方法和手段。

疲劳缺口系数Kf与理论应力集中系数Kt之间的关系

疲劳缺口系数Kf是表征缺口部位疲劳强度降低程度的参量,这一系数在结构抗疲劳设计中经常被使用.一般认为Kf与理论应力集中系数Kt呈线性关系,线性的斜率与不同材料类别(铝合金、钛合金和钢)有关.通过对大量不同材料、不同应力比和不同缺口试样形式的高周疲劳极限的系统分析,发现大多数情况下K f与Kt的呈线性关系,但有些情况下二者不服从线性关系.Kf与Kt的关系除与材料类别有关外还与实验的应力比有关.     

Study on Relationship Between Concentration of Complexes and Components of Coating

Zn-Fe alloy coating was electrodeposited from acidic sulphate bath, and the relationship between real concentration of complexes ( [ ZnL ] and [ FeL ] ) in the bath and components of coating was studied. As the added 7H2O is increased from 40 g/L to 80 g/L, the ratio of iron complex to total complex increases from 50.02% to 66.23% , simultaneously the iron content in coating increases from 8.26% to 13.77%. As the added (NH4)2SO4 is increased from 40 g/L to 80 g/L, ratio of iron complex to total complex increases from 58.65% to 60. 37%, simultaneously the iron content in coating increases from 9.28% to 11.92%. The results indicate that, in the process of alloy deposition, variation of relative concentration of metallic complexes in the bath can lead to variation of components of coating proportionally. Accordingly, the variation of components of coating may be approximately deduced by calculating the variation of relative concentration of metallic complexes. Whereas, in order to judge the components of coating quantificationally, more research work need to be done on some other factors, such as the value of pH, current density, additives, etc.     

Granulations in a Fluidized-Bed: Effect of Binders and Their Concentrations on Granule Growth and Modeling the Relationship Between Granule Size and Binder Concentration

Lactose and mixture of lactose and microcrystalline cellulose (1:1) were granulated in a fluid-bed equipment using PVP, acacia and gelatin as binders. The effect of these binders, their concentrations, and volume of granulation liquid on granule growth and granule sue distribution was studied. It has been shown that individual binder and binder concentration affect granule growth and growth mechanism. Also, the volume of granulation liquid and part dissolution of excipients being granulated contribute significantly to the granule size and size distribution. On the basis of granule growth data, a mathematical relationship which relates granule size as a function of binder concentration is proposed. Granule growth constant for the binders is computed from the granule size against binder concentration data. The constant describes granule growth pattern, and is termed as binder coefficient, β. The numerical value of binder coefficient, which varies with the binder, indicates relative activity and effectiveness of each individual binder. A relationship between the binder coefficients is also established. This is shown to predict granule sue for a binder relative to another binder for the desired concentration. The validity and the applicability of the proposed relationship was tested on the data obtained during present investigations as well as on data reported by other authors.

On Intrinsic Bounds in the Nullstellensatz

 Let k be a field and  f ₁, . . . ,  f _s be non constant polynomials in k[X ₁, . . . , X _n ] which generate the trivial ideal. In this paper we define an invariant associated to the sequence  f ₁, . . . ,  f _s : the geometric degree of the system. With this notion we can show the following effective Nullstellensatz: if δ denotes the geometric degree of the trivial system  f ₁, . . . ,  f _s and d :=max _j  deg( f _j ), then there exist polynomials p ₁, . . . , p _s ∈k[X ₁, . . . , X _n ] such that 1=∑ _j  p _j  f _j and deg p _j   f _j ≦3n ²δd. Since the number δ is always bounded by (d+1) ^n-1 , one deduces a classical single exponential upper bound in terms of d and n, but in some cases our new bound improves the known ones.

On the Relationship Between Microstructure of the Cortical Bone and its Overall Elastic Properties

The relationship between microstructure of the cortical bone and its effective elastic properties is discussed. We utilize results of Kachanov et al (1994) on materials with cracks/pores of diverse shapes. Bone's microstructure is modeled using available micrographs. The calculated anisotropic elastic constants for porous cortical bone are compared with available experimental data. For Young's moduli and shear moduli the agreement is good, whereas Poisson's ratios differ significantly. Possible reasons for this difference are discussed. This revised version was published online in August 2006 with corrections to the Cover Date.     

On the Compliance Contribution Tensor for a Concave Superspherical Pore

Erosion and corrosion result in potential material loss. The erosion is a physical phenomenon but corrosion is chemical one. The study of these two phenomena, as functions of time and temperature, would lead to a better understanding of glass surface damage. Results allow one to determine the effects of immersion time, temperature of the water bath and residual stresses generated by Vickers indentation on the radial crack and topography of the imprint on the surface of a soda-lime silica glass. Water corrosion effects are different at the imprint corner and the radial crack tip as compared to edges and faces.
