  1. Using the advanced technology by its head office ( newkey co., ltd. ), it produces various kinds of alumina black and white ceramic products. the component alumina ceramics, which are widely used in electron components, devices, electrical products, enjoy low loss of high frequency, high insulating strength, good specific volume resistance, small dielectric constant, high mechanical intensity and excellent airtightness and thermal and chemical stability

    本公司根據目前市場需求，生產出各種型號的黑、白陶瓷產品，廣泛應用於電子、電工、化學工業、紡織工業、水暖、宇航、環保等諸多方面，系列產品有高頻損耗少，比體積電阻大，介電常數小，強度高，氣密性、熱穩定性、化學穩定性好等特點。
  2. During the low strain dynamic test of the foundation pile, the adoption of the velocity sensor to the direct measurement of the relative displacement of the pile head is helpful to reducing the improper dependence upon the measured intrinsic frequency valuesof the pile soil system in calculating vertical bearing capacity of the single pile, and is hence conducive to raising the accuracy of the calculated vertical bearing capacity of the single pile

    基樁低應變動測中，採用速度傳感器直接測出樁頭的相對位移，在推算單樁豎向承載力時，有助於降低對樁土體系固有頻率測定值的過分依賴，從而有利於提高單樁豎向承載力推算值的準確程度。
