Among them, operating with the power from the tip of the thumb is called finger - tip pushing ; in which the interphalangeal joint of the thumb is fixed at the back - stretching position, operating with the force from the whorled surface is shao - shang point at the side of the thumb - radius is called lateral pushing, in this operation, the operator slightly flexes his wrist joint with index finger, middle finfer, ring finger and little finger naturally stretching forward in the finger - separating pattern
以拇指端峰為著力點操作的稱指峰推；操作時，拇指之間關節固定在背伸位，以羅紋面為著力點的稱羅紋推；以拇指橈側少商處為著力面的又叫偏峰推，此法操作時腕關節略屈，食、中、無名、小指向前自然伸開，成散手狀。 -
The position of the trajectory depends on the ratio of bead - to - fluid density, the ratio of bead - to - disc radius and the reynolds number which describes the operating conditions of the stirred media mill. by means of the beads motion in the calculation domain, the influence of different comminution operation parameters on comminution results is discussed. those parameters mainly include the beads size, beads density, stirrer angular speed and liquid density and viscosity etc. those parameters are optimized so that the comminution results are improved
通過研究研磨介質在計算域內的運動來探索不同的粉磨技術參數對粉碎效果的影響，這些粉磨技術參數主要包括磨介尺寸、磨介密度、攪拌盤速度、液流密度及粘度等；通過優化這些參數來達到提高攪拌盤式攪拌磨粉磨效果的目的。 -
Author thinks that the direction of the maximum plastic distortion along a constant radius around the crack tip may be considered as the direction of shear - mode fracture ( named pmax - criterion ) and the load when located shear band prongs the ligament in the front of crack tip is regarded as the limited load of shear - mode fracture. ( 3 ) the fad ( fracture assessment diagram ) of titled crack is proposed based on achievements of mesomechanics about i - ii complex ductile fracture of metal, and the titled crack is classified two kinds : void - mode fracture is assessed by fracture assessment curve, and shear - mode fracture by limited load. ( 4 ) using a fe program based on plantle - ressue theory to calculate some mesomechanical parameters, a flange joint structure of a high pressure vessel ( design pressure 31. 4mpa and the thickness of the hemispherical head is half of that of shell. ) is analyzed to determine whether the structure under operation pressure is safe or not, forecast the mode of potential invalidation and argue for the rationality of design of the structure
試件的整體斷裂為剪切型，但在試件芯部裂尖鈍化區中部出現了韌窩型啟裂並有一定的擴展，說明局部較高的應力三軸度也會使韌窩型機制得以發展，但是不改變試件整體的剪切型斷裂模式；對韌性斷裂的剪切模式的細觀機理做了一定的探討，並且提出了含裂紋構件剪切型斷裂的宏觀判據：認為裂紋前方的集中剪切帶中與裂紋尖端等半徑處最大有效塑性應變出現的方向可以作為裂紋剪切斷裂的方向（可簡稱為_ （ pmax ）準則） ，集中剪切滑移帶貫穿裂紋前方承載韌帶時的載荷可以作為極限載荷；本文運用金屬韌性斷裂細觀力學在一復合型韌性斷裂方面的研究成果，採用失效評定圖的形式，提出了傾斜裂紋的安全性評定方法的基本框架。 -
