Treatment of femoral neck fracture with compressive cannular screw fixation

空心加壓螺紋釘固定治療股骨頸骨折

As the temperatures increase through different ranges, the flakes will form as flat hexagonal plates, followed by hollow columns, needles, and then back to lacy hexagons between 25 f and 32 f

當溫度通過不同的范圍上升時，雪花將會形成平面六角板，其次是空心柱和針頭狀，然後在25 ? 32度之間又會變回花邊六面體。

Considering that the traditional cast - in - situ r. c. shear wall structure has such disadvantages as large self - weight, stiffness and seismic forces, poor ductility and energy wasting, the subject puts forward a new type of hollow shear wall of r. c. stucture with seams which has the advantages of not only high bearing capacity but also small self - weight, stiffness and good ductility and so on. it is a new kind of earthquake resistant and energy - saving structure

針對傳統現澆鋼筋混凝土剪力墻結構自重大、剛度大、自振作用大、延性差以及保溫隔熱等建築節能性能差等諸多缺點，本課題對其進行改革，提出了一種新型的帶縫空心鋼筋混凝土剪力墻結構，此結構具有自重輕、剛度小、延性及變形能力好、耗能能力強等優點，是一種新型抗震、節能的承重結構。

For the sake of improving the seismic behavior of shear - wall, a new structure system named hollow shear - wall which has such characteristic as low gravity, rigidity and good ductility are presented in this paper. the paper studies the seismic behavior of r. c hollow shear wall and basic members

針對普通剪力墻結構的弊病，本課題組提出空心剪力墻板這一新的結構形式，它具有良好的節能性能，又具有自重輕、剛度小、延性好的特點。
