  This study presents a novel common approach to analysis the transmission angle of a type of manipulators. Here, two types of transmission angles are defined to evaluate the kinematic performance of parallel manipulators, with which the direct and indirect singularities can be identified in a straightforward manner. The relationships between the angles and condition number of Jacobian which is a vital performance index for parallel manipulators are investigated throughout the workspace by taking both the Diamond and Delta parallel manipulators as an example. A simple method for determining the workspace bounded by the angle constraints is proposed which make less time be cost in the optimization or any other design procedure. Considering the effects of transmission angles, a global and comprehensive index is presented. The kinematic optimization of Diamond manipulator has been taken as an example to illustrate the effectiveness of this approach.

  The changes of microbial biomass carbon (MBC) and nitrogen (MBN) and microbial community in the topsoil of the abandoned agricultural land on the semi-arid Loess Plateau in China during the natural succession were evaluated to understand the relationship between microbial community and soil properties. MBC and MBN were measured using fumigation extraction, and microbial community was analyzed by the method of fatty acid methyl ester (FAME). The contents of organic C, total N, MBC, MBN, total FAME, fungal FAME, bacterial FAME and Gram-negative bacterial FAME at the natural succession sites were higher than those of the agricultural land, but lower than those of the natural vegetation sites. The MBC, MBN and total FAME were closely correlated with organic C and total N. Furthermore, organic C and total N were found to be positively correlated with fungal FAME, bacterial FAME, fungal/bacterial and Gram-negative bacterial FAME. Natural succession would be useful for improving soil microbial properties and might be an important alternative for sustaining soil quality on the semi-arid Loess Plateau in China.
