✦ Synopsis
In this paper, using the singular quasi-compatible ®nite element (SQCE) method advanced by Zhichao et al. (1990), the in¯uence coecients of size on a plate with two parallel cracks are studied. A large quantity of numerical computations are carried out, and various data tables and curves are obtained. On the basis of the computation results, the dierences between the ®nite size crack plate and the in®nite size crack plate are discussed, and the interference between the two parallel cracks is analysed.

A labeling of graph G with a condition at distance two is an integer labeling of V(G) such that adjacent vertices have labels that differ by at least two, and vertices distance two apart have labels that differ by a t least one. The lambda-number of G, A(G), is the minimum span over all labelings of
## Abstract The cooling performance of a plate‐fin‐type heat sink equipped with a cooling fan was investigated experimentally. The heat sink was 80 mm long, 43 mm wide, and 24 mm in height (including the 4‐mm‐thick base). The cooling fan was 40 × 40 × 15 mm and was set to direct the air flow vertic
