From the petrological study of ore-hosting focks which contain large anorthits crystals and the occurrence and chemical composition of anorthites and related minerals,the authors consider that the large anorthite crystals are of authigenic origin. The distribution characteristics of anorthites,i.e.,they are distributed along the bedding and structurally weak zones but not restricted to synsedimentary slump structures,and the relationship for some elements between anorthites and other minerals indicate that anorthites have resulted from reaction of circulating alkaline solutions rich in Al and Si with carbonated during the Indosinian *** results of this work suggest that the association of authigenic anorthites with bedded orebodies in the Dachang ore field may be the evidence that the mineralization is related to circulating underground hot waters.

In this paper, an experimental analysis of overcoming obstacle in human walking is carried out by means of a motion capture system. In the experiment, the lower body of an adult human is divided into seven segments, and three markers are pasted to each segment with the aim to obtain moving trajectory and to calculate joint variation during walking. Moreover, kinematic data in terms of displacement, velocity and acceleration are acquired as well. In addition, ground reaction forces are measured using force sensors. Based on the experimental results, features of overcoming obstacle in human walking are ana- lyzed. Experimental results show that the reason which leads to smooth walking can be identified as that the human has slight movement in the vertical direction during walking; the reason that human locomotion uses gravity effectively can be identified as that feet rotate around the toe joints during toe-off phase aiming at using gravitational potential energy to provide propulsion for swing phase. Furthermore, both normal walking gait and obstacle overcoming gait are characterized in a form that can provide necessary knowledge and useful databases for the implementation of motion planning and gait planning towards overcoming obstacle for humanoid robots.

Te forearm distal bone fracture is the most com-mon fracture in children. Scaphoid frac-ture is rare because the scaphoid is largely car-tilaginous in children. Some cases associating both distal radius and scaphoid fractures were reported in the literature. Scaphoid fracture often occurs without displacement and can be easily overlooked. We re-ported a case of children wrist injury combining scaphoid fracture with ipsilateral distal fracture。

This paper deals with a design approach of a gait training machine based on a quantitative gait analysis. The proposed training machine is composed of a body weight support device and a cable-driven parallel robot. This paper is focused on the cable-driven robot, which controls the pose of the lower limb through an orthosis placed on the patient＇s leg. The cable robot reproduces a normal gait movement through the motion of the orthosis. A motion capture system is used to perform the quantitative analysis of a normal gait, which will be used as an input to the inverse dynamic model of the cable robot. By means of an optimization algorithm, the optimal design parameters, which minimize the tensions in the cables, are determined. Two constraints are considered, i.e., a non-negative tension in the cables at all times, and a free cable/end-effector collision. Once the optimal solution is computed, a power analysis is carried out in order to size the robot actuators. The proposed approach can be easily extended for the design study of a similar type of cable robots.

Passively Q-switched thulium doped fiber laser(TDFL)has been successfully demonstrated using gold nanoparticles(GNPs),which were embedded into polyvinyl alcohol as saturable absorber(SA).The stable self-starting Q-switched laser was generated to operate at 1891 nm when a tiny piece of the prepared film was slot in between two fiber ferrules and incorporated into the laser *** repetition rate can be adjusted from 48.54 kHz to 49.64 kHz while the pulse width decreased from 3.52μs to 2.38μs with the increase of 1550 nm pump power from 840 m W to 930 m *** corresponding pump power output power linearly increased from 3.62 m W to 6.3 m W with a slope efficiency of 2.53%.The maximum peak power and pulse energy were recorded at about 39 m W and 0.12μJ,respectively at pump power of 930 m *** Q-switching operation was caused by the surface plasmon resonance absorption of GNPs.
