  3. Based on virtual prototype, engineers can find underlying problems just during products design by simulating the mechanical system, and revise them quickly so as to throw off the physical prototype, which not only can save the cost of design and manufacturing and reduce the cycle of products development, but also can elevate products " performance and enhance products " competition

    通過虛擬樣機技術，工程師可以通過機械繫統運動模擬，在產品設計階段發現產品設計中的潛在問題，並快速進行修改，減少了對於物理樣機的依賴，這樣不僅可以節省成本，縮短產品開發周期，而且可以提高產品性能，增強產品競爭力。
  4. This study dealt with the identification and evaluation of 8 maize populations from tropical and subtropical regions under the ecological conditions in zhengzhou, henan. results showed that the significant delaying days to shed and days to silk, discoordinating for the development of male and female, higher plant and ear height, more leaf numbers, high barreness, worse performance of ear traits compared with the ck ( temperate population ) were found, which showed the tropical and subtropical populations could not be utilized directly under the ecological conditions in zhengzhou. by using selection and improvement the tropical and subtropical populations can be used to broaden the genetic base of temperate maize breeding, beause of the greater genetic variation and higher selection potential within each population. the different performances of the sensitivity to photoperiod were observed among different tropical and subtropical populations and different traits. the asi, time to silk, ear height, leaf numbers, grain yield per ear could be used as the good evaluation traits for identifying the sensitivity to photoperiod

    對8個熱帶、亞熱帶玉米群體在鄭州生態條件下的表現進行鑒定和評價，結果表明，熱帶、亞熱帶群體散粉、吐絲期顯著延遲，雌雄不協調，植株和穗位高、葉片數增多、空稈率高，結實性差，果穗性狀均明顯劣於溫帶對照，在鄭州生態條件下不能直接利用，但是群體內具有較大的遺傳變異和選擇潛力，可以用來拓寬現有玉米種質的遺傳基礎；不同熱帶、亞熱帶群體的光周期敏感性不同；不同性狀對光周期反應的敏感程度不同， asi 、吐絲期、穗位高、葉片數、穗粒重可作為鑒定光周期敏感性的較好指標
