Mechanical Engr Dict (Jpn-Chi)

About this app

Do you know how to say "三角形齿花键轴" in Japanese? With this application you can immediately find the equivalent of "セレーション軸". At home, at work and on the go, translators, students and professionals of mechanical engineering will often encounter technical terms related to machine tools, power generation, industrial equipment and the like for which they need to quickly look up their Japanese or Chinese translations. The Mechanical Engineering Dictionary, compiled by The CJK Dictionary Institute (CJKI) in Japan, is the only application on any mobile platform that provides comprehensive coverage of mechanical engineering terminology. This application, which provides a user interface in both Japanese and Chinese, as well as English, includes both Chinese-Japanese and Japanese-Chinese dictionaries that provide access to a total of approximately 25,000 technical terms. While several Japanese-Chinese general vocabulary dictionaries are available for the iPhone, there are few specialized dictionaries that meet the specific needs of professionals, translators and information technology students, while those that are available are prohibitively expensive and of limited coverage. With this application, you get a database of technical terms with extensive coverage at your fingertips for a reasonable price. Please note: This app contains translation equivalents for each term, not explanations of each term's meaning. FEATURES * Both dictionaries combined contain over 25,000 entries * Designed for both Chinese and Japanese users * Covers various subdomains including machine tools, welding, robotics, hydraulics, power generation, and much more * All this data is instantly accessible right on your device - no Internet connection required * What was that word you just looked up?
