Engineering changes are not just critical evidences for engineering settlement between the two contracting parties in engineering construction, but also involve in the reallocation of responsibilities and risks such as laws, regulations, structural safety, technical standards, engineering scope, government acceptance, government supervision on quality and safety, health and epidemic prevention, planning, quality standards and fire control, etc. The feasibility evaluation on engineering changes under bill of quantities mode can better reflect its importance and necessity. Based on summary and review of a large number of examples of engineering changes, the thesis puts forward evaluation ideas and suggestions for engineering changes under bill of quantities mode, and hopes to provide certain instructions for management of subsequent engineering changes in the future.

Modeling and simulating of sea clutter is the research focus in theoretical field of radar signal processing all the time and it has important application in technology of CFAR detection. This paper introduces the statistical properties of Inverse Gaussian Compound Gaussian distribution (IG-CG) and according to theory of spherically invariant random process (SIRP), proposes a simulating method of radar clutter based on IG-CG model. The results of experiment proved that random vectors generated by the method fit theoretical clutters of IG-CG distribution both in amplitude aspect and power spectral density aspect. Through the test of chi-square goodness of fit, random vectors satisfy theoretical distribution under confidence interval 0.95.

The high production cost of solar cells has been a major hindrance to the photovoltaic technology's market penetration. Concentrating photovoltaic (CPV) technology uses concentrated sunlight to achieve a cost-effective solar energy. However, operating temperature of solar cells increases significantly as sunlight is densely concentrated, so thermal management is an important issue in the development of concentrating photovoltaic systems. Computational Fluid Dynamics (CFD) has the potential to assist in the specification of operating conditions and designs of the CPV cooling systems that minimise the temperature and temperature gradients of the solar module in the PV receiver. This paper reports the construction of a 10-silicon CPV cell linear liquid-immersed solar receiver and a CFD model of this receiver using the commercial code, Fluent 6.3. Model results for the 10-cell module in the receiver are reported.

The physical weak-discontinuous problem of an interfacial crack between homogeneous materials and functionally graded materials (FGMs) is studied based on Reissner's plates considering transverse shear deformation effect. The higher order crack tip fields of homogeneous materials and FGMs regions are obtained by the eigen-expansion method. The normalized stress intensity factors(SIFs) and stress distributions near the crack tip are computed and compared by means of the higher order fields and singular fields, respectively.
