He Is “Good”At History

Jack went to school to study history, but when he finished his first year, he didn't pass the exam and the teacher said to him, "You have to leave school." When the boy's father heard the news, he was worried. He came to the school to see the teacher. He found the teacher in the office and asked the teacher to let Jack study in the school the next year.     

Mesh parameterization based on edge collapse

Parameterizations that use mesh simplification to build the base domain always adopt the vertex removal scheme. This paper applies edge collapse to constructing the base domain instead. After inducing the parameterization of the original mesh over the base domain, new algorithms map the new vertices in the simplified mesh back to the original one according to the edge transition sequence to integrate the parameterization. We present a direct way, namely edge classification, to deduce the sequence. Experimental results show that the new parameterization features considerable saving in computing complexity and maintains smoothness.     

Teacher’s Role in the Oral English Class

English speaking has been paid more attention today, especially in the age of globalization. Teachers are attempting to find out more effective methods to enhance the teaching results of English speaking. Facing the great demands and present difficulties of oral English classes, teachers have to conduct more study and practice to find out what roles that an oral English teacher has to take in the oral English classroom. Compared with the traditional teaching role in the English classroom, an oral English teacher has to fulfill more than one role in the classroom teaching so as to provide better learning conditions for students. Lacking more exposure to the real interaction with native speakers, students expect the oral English teacher to be a creator of the language environment. With various teaching and learning activities in the oral English classroom, the teacher has to be a good organizer to ensure every student to achieve improvement. An oral English teacher also has to correct students’language errors while ensuring the smooth progress of the classroom teaching. Only when an oral English teacher make clear what roles he or she has to take in the classroom can he or she achieve effective teaching.

Surface breakdown of printed circuit board under magnetic field with reduced pressure

Epoxy resin laminate onto which a pair of copper foil was printed was employed as test samples.The samples were placed in an artificial atmospheric chamber, which was vacuumed by a rotary pump from 100 kPa to 5 kPa.The magnetic field was produced by permanent magnets that were assembled to make E×B drift away from, into and parallel to the sample surface, respectively.Magnetic flux density was adjusted at 120 mT, 180 mT and 240 mT respectively.By applying a negative bias voltage between the electrodes, the time to surface breakdown was recorded.Obtained results show that when E×B is into the surface, the time to the breakdown is shortened;when E×B is away from the surface, the time to the breakdown is delayed;when E×B is parallel to the surface, the time to the breakdown remains approximately the same as the case without magnetic field.With the decrease of pressure, the time to the breakdown increases and the effect of magnetic field on breakdown appears to be strengthened.     

Love and Time

Once upon a time,there was an island where all the feelings lived: Happiness,Sadness,Vanity and all of the others including Love. One day it was announced to all of the feelings that the island was going to sink to the bottom of the ocean.All the feelings prepared their boats to leave except Love.She wanted to hold out and try to save the
