It had been believed that the genesis of Gejiu tin deposits were granitic mineralization of Yanshanian epoch by most researchers for a long time. However, recently the authors obtain a great deal of information to indicate that the Gejiu tin deposits are occured as mineralization of many time periods and many sources, being divided as three metallogenic series namely the seabed basic volcano- metallogenic series, the seabed exhalative hydrothermal metallogenic series in the Indo-Chinese epoch and the granitic superimposed metallogenic series in the Yanshanian epoch. The metallogenic pattern may be summed up as “rift setting—the volcano-sedimentary metallogenises—the exhalative hydrothermal sedimentary metallogenises—the granit rebuild superimposed metallogenises”.The paper demonstrater the metallogenic viewpoint in terms of the trace rare earth element, stable isotopes and fluid inclusion.

In recent years, prediction of the behaviors of micro and nanostructures is going to be a matter of increasing concern considering their developments and uses in various engineering fields. Since carbon nanotubes show the specific properties such as strength and special electrical behaviors, they have become the main subject in nanotechnology researches. On the grounds that the classical continuum theory cannot accurately predict the mechanical behavior of nanostructures, nonlocal elasticity theory is used to model the nanoscaled systems. In this paper, a nonlocal model for nanorods is developed, and it is used to model the carbon nanotubes with the aim of the investigating into their longitudinal vibration. Following the derivation of governing equation of nanorods and estimation of nondimensional frequencies, the effect of nonlocal parameter and the length of the nanotube on the obtained frequencies are studied. Furthermore, differential quadrature method, as a numerical solution technique, is used to study the effect of these parameters on estimated frequencies for both classical and nonlocal theories.

An investigation into the vibration of harmonic drive systems
M. Masoumi, H. Alimohammadi
Frontiers of Mechanical Engineering 2013, Volume 8, Issue 4, Pages 409-419 doi: 10.1007/s11465-013-0275-5
Harmonic drive systems are precise and specific transmission gear systems which are beneficial in terms of the high transmission ratio and almost zero backlash. These inherent and spectacular properties result in using this mechanism in robotic and space sciences where the precision and lightwieght play an important role. This paper presents a vibration analysis of harmonic drive systems using the shell theory. Equations of vibration for the flexspline and the circular spline of the system are derived and used to find the natural frequencies for both parts and, moreover, vibration response of the system under the operating condition is calculated. Also, obtained vibration equations are utilized to study the effects of different involved parameters such as the geometry of the flexspline and its gear tooth, eccentricity, and unbalancing on the vibrational behavior of the system.
