So science and technology progress can be as a important factor to evaluate the results of CI’s transformation of economic growth pattern and of CI’s exploring way of sustainable development.
WU Wei-wei, LI Qi-ming’s paper, the measure of science and technological progress contribution of Jiangsu’s CI compared with Shanghai and Zhejiang, found that CI’s TFP in the eastern region was also low[3].
It includes: (1) architectural engineering economic output which refers to all kinds of architectural engineering output value listed in the budget projects. (2) equipment installation project value which refers to the value created in the process of equipment installation, not including installed equipment’s value. (3) repair output value of buildings and structures which refers to the value created through the repairs, but does not include the repaired buildings’ or structures’ value and not include the value of the repaired equipment. (4) non-standard equipment manufacturing output value which refers to the raw materials’ value and manufacturing cost value in the process of manufacture that were not stereotypes, non-standard production equipment and the value created by accessory factory constructing non-standard equipment project for its mother-enterprise.
rate of science and technology and its contribution rate Of K, contribution rate of L and contribution rate of M are 48.65%, 40.62% and 10.77% in sum average respectively in the period of “10th ,11th five-year plan”.

This is achieve using a semiconductor material which produce free electrons or holes when expose to UV radiation.
Due to growing interest in UV detector, various materials have been tried by researchers to improve its efficiency.
Saturation in resistance value is observed after the sensor exposed above 4 min under UV light to indicate the maximum amount of free electrons released by incident photon is reached Acknowledgement The author also would like to acknowledge Microwave Technology Centre (MTC), Faculty of Electrical Engineering, UiTM, NANO-SciTech Centre (NST), Institute of Science, UiTM and Faculty of Applied Sciences, UiTM for use of the characterizations facility.

Cu is a metal with wide applications in microelectronics and it has drawn increasing attention as an alternative to Al alloys as the metallization materials for microelectronic devices,because of its low resistivity (1.63 µΩ·cm), high and stress migration resistance, and high melting point.
High pure Cu (99.999 %) was used as source material, and it was heated at above 1800 oC.

Up to now for to, the research related to high current density MAG welding and DCEN MAG welding still has been lack of the thorough study.The stability of MAG arc is relatively weak compared with non-consumable gas arc shielded welding, for which includes many factors: welding parameters, shielded gas component, welding wire material and diameter, wire extension, wire melting, droplet transfer etc.
Wire is cold cathode materials, and cathode drop is much higher than anode[2].

Introduction
Important parameters identified that influence the surface quality generated during lapping process
for a given workmaterial with given abrasive (material and grain size) are the lapping speed, the
lapping load and the abrasive, concentration [1,2].
