Based on the trip faults data of 10kV and 20kV distribution lines which come from actually power grid in China, this paper has done a large number of statistical analyses and investigations. Trip faults are classified and analyzed by fault positions, monthly changes, fault causes and so on. Preliminary analysis suggests that main factors which lead to trip faults are outer forces, meteorological conditions, improper operation and maintenance, quality of equipment and design processes. Rains, strong winds and lightnings have the worst impact on distribution lines in a period from June to August. External forces caused the most faults on conductors, towers and stay wires. According to different failure reasons, countermeasures are put forward pointedly,so can provide references for improving power supply reliability in distribution network.

AbstractHigh resolution images, obtained during July 11, 1991 total solar eclipse, allowed us to estimate the degree of solar corona polarization in the light of FeXIV 530.3 nm emission line and in the white light, as well. Very preliminary analysis reveals remarkable differences in the degree of polarization for both sets of data, particularly as for level of polarization and its distribution around the Sun’s limb.

The Individual

Individuals with Rett syndrome (RS) present with a complex profile. They benefit from a multidisciplinary approach for diagnosis, treatment, and follow-up. In our clinic, the Communication Matrix © (Rowland, 1990/1996/2004) is used to collect data about the communication skills and modalities used by those with RS across the lifespan. Preliminary analysis of this data supports the expected changes in communication behaviors as the individual with RS ages and motor deficits have a greater impact.
