That is the so-called eigenvalue sensitivity and eigenvector sensitivity ,(m=1, 2….) indicate structure design parameters (mainly refers to the size of the structure, geometry shape or material parameters, also including mass, stiffness and damping elements) or design variable.
Taking the five main parameters of the crankshaft such as thickness of crank arm (Th_cr), diameter of main journal (D_mj), length of main journal (L_mj), diameter of crank pin journal (D_cpj) and length of crank pin journal (L_cpj) as design parameters, the sensitivity of the first five-order constraint frequencies versus the five design parameters is calculated.

Conjoint analysis was used to analyze how the attributes such as the brand, the price, the raw materials, the environmental certification and the fluorescent additives of the rolling paper affect its purchase on the basis of the data from a survey among the consumers in Changsha.
It was based on those attributes influence most to consumer preferences.On the basis of survey from consumers, analyzed on literature concerning rolling paper,and consulted from papermaking enterprises on information of paper attributes,the attributes of brand, price, raw materials, environmental certification and fluorescent additives were selected for investigation.
After all kinds of papermaking raw material were in detail, many consumers had changed their view of regenerate pulp, as the data showed that the part-worth of regenerate pulp was 0.177, more higher than other two materials.

Nano-polycrystalline materials exhibit distinctly different mechanical and physical properties to conventional materials.
Introduction Nano-polycrystalline materials exhibit distinctly different mechanical and physical properties to conventional materials.
For micro-grained materials this volume fraction is below 0.01% but, for nanopolycrystals it may exceed 25%.
