Flugdach; Ausnutzbarkeit des Bauplatzes; Begriff "Nebengebäude"; Schwimmbad

Die mit Flugd?chern überdeckten Grundfl?chen sind blo? auf die gesetzlich begrenzte Ausnutzbarkeit des Bauplatzes anzurechnen, nicht jedoch auf den durch den Bebauungsplan beschr?nkten Teil. Schwimmb?der sind mangels raumbildender Ausgestaltung keine Geb?ude. Gesondert in Erscheinung tretende Teile eines Geb?udes iSd 82 Abs 1 wr BauO k?nnen nur raumbildende Anlagen sein.

直齿轮“渗碳-温挤”渗碳层厚度分布模型

采用“渗碳-温挤压”工艺成形直齿轮，可使齿轮性能大幅度地提高，但经渗碳处理后的坯料，在塑性成形齿轮时，由于渗碳层流动不均匀，使齿面上不同部位渗碳层厚度不同，而沿齿面的渗碳层厚度应依据从齿顶到齿根不同工作特性的要求合理分布。通过分析齿轮失效的主要原因，提出了齿面上不同部位渗碳层厚度的基本要求，建立了直齿轮渗碳层厚度分布模型，并根据该模型，提出了采用“渗碳-温挤压”工艺加工直齿轮时坯料所需碳层的计算方法。研究表明：所建立的直齿轮渗碳层厚度分布模型为新工艺的实施提供了完善的目标和简明的计算方法。     

Time dependent analysis of short-range monopole wake fields driven by accelerated electron beams

Combinations of integral transforms and Green's function are employed in order to obtain the distribution of the short-range monopole wake fields driven by accelerated electron beams in a cylindrical cavity. This constituted an alternative but simpler and more versatile method to the normal mode expansion which we used earlier to solve for such a distribution (Salah and Dolique, Nucl. Instr. and Meth. A 431 (1999) 27). Whereas direct comparisons of the resulting analytical expressions are found difficult to directly compare, numerical illustration of results obtained from both approaches show excellent agreements and hence confirm the fact that both approaches are equivalent.

Thermal evaluation of a “Winter House”

In this paper, the transient thermal model of a “Winter Houseȁd; has been presented for a cold climatic region of Srinagar in India. In order to reduce the fluctuations in living room temperature, the effect of an isothermal mass has been incorporated in the thermal model. An analytical expression for room temperature has been derived to evaluate the performance of the “Winter Houseȁd; by incorporating the effect of movable insulation during the night. Numerical calculations were done in terms of system as well as climatical parameters. Some isothermal mass, like water, has been considered to stabilize the room temperature throughout the day and right. For further heating, the effect of the roof as an air collector has also been taken into account.
