In literature, Hernan et al. reported that elevating the reaction temperature with an excess of both OH ions and oxygen gas was helpful to obtain purer Mn3O4.

Yuan et al. considered the bridge structure as a simply supported Euler-Bernoulli beam and developed dynamic load identification methods using modal superposition principle and least-squares method [5].
Chan et al and Yu and Chan performed a series of systematically researches and experiments on moving loads identification methods [6,7,8], which including Interpretive Method I [4], Interpretive Method II [9], Time Domain Method [10] and Frequency Time Domain Method [11], proposed a Moving Force Identification System (MFIS) theory for moving loads on the bridges, and analyzed the merits, weakness and applicability of these four methods.

Recent investigations by Rahim et al. [6] and Li et al. [7] on drilling of titanium alloys at higher speeds have indicated that peck drilling method and WC-Co spiral drill point are accompanied by a higher tool life and low cutting force.

Arul et al [7] found that tool wear reduces as feed rate increases from 0.04 to 0.2 mm/rev when fibre composite laminates were drilled using High Speed Steel (HSS) drills.
According to Jia et al. [15], cutting speeds from 20 to 90 m/min and feed rate below 0.5 mm/rev are normally chosen for drilling of the CFC materials.

In a comprehensive review on the sulphate attack, Hekal et al [6] pointed out that, in most cases, the loss of adhesion and strength, not expansion and cracking is the primary manifestation of sulfate attack.
