  1. Dr mike knapton, director of prevention and care at the bhf ( the british heart foundation ), said it was a " deadly serious " problem

    英國心臟協會正在進行一系列活動，鼓勵民眾每天運動讓心臟加速跳動三十分鐘，因為他們發現每十五分鐘就有人是因身體缺乏活動而死亡的。
  2. The work reported here, adaptive numerical simulation was developed to adjust the magnitude of bhf continuously during the simulation process

    摘要拉裂和起皺是板材拉深過程中的主要失效方式，研究表明，合理的壓邊力能有效降低拉深失效的可能性。
  3. Taking typical drawing workpiece circular cup as the research object, a stamping technological parameters artificial neural network ( ann ) model for bhf forecast has been built up

    摘要壓邊力是板料成形中的一個重要的工藝參數，也是板料拉深成形中的重要控制手段。
  4. Based on energy theory, wrinkling criterion in deep drawing for axisymmetric parts is derived to take geometry parameters, friction coefficient, material properties, and the law of critical blank - holder force ( bhf ) of side wall wrinkling in the constraint condition of initial wrinkling into account

    從能量平衡原理出發，通過對屈服準則的線性化處理，推導了考慮幾何參數、摩擦系數和材料性能參數、板材皺曲時約束條件的軸對稱拉深成形過程中側壁起皺臨界壓邊力的變化規律，給出了皺曲判據。
  5. The bhf stresses that the research is not bad news for cyclists in cities

    Bhf強調這項研究對城市中的騎車人來說不是壞消息。
  6. Researchers at the centre for cardiovascular sciences at the royal infirmary of edinburgh have been awarded bhf funds of nearly 1. 2million to undertake a five year collaborative research programme investigating how diesel exhaust pollution causes sickness in blood vessels that can lead to heart and circulatory disease

    愛丁堡皇家醫院心血管科學中心的研究人員已經接受了bhf提供的約120萬歐元的基金，支持其開展一個五年的合作研究項目，調查柴油排放污染如何對血管疾病產生影響，而這些影響會導致心臟與循環系統的疾病。
  7. Therefore, drawbead is employed together with bhf to control the drawing process, and several typical layouts of drawbead are analyzed and compared via fea ( finite element analysis ), with the most effective one then being applied to stamping experiments

    因此，文中採用拉延筋和壓邊力來共同控制拉延成形，並通過有限元分析比較了幾種典型的拉延筋布置方案，選擇其中最有效的一種進行試沖試驗。
