According to the experimental data, it is found that the circumferential diffierence of heat transfer characteristics occurres due to the effects of thermal acceleration and buoyance in the inclined smooth tube at supercritical pressure.

实验结果表明：在超临界压力区域，倾斜光管内可能由于受到热加速度和浮力的综合作用，倾斜光管传热特性沿周向是不均匀分布状态，通常管内顶部的壁面温度比底部高，在大比热区发生传热恶化和传热强化的现象，低质量流速和高热负荷条件下会发生传热恶化现象，高质量流速下会发生传热强化，避免壁温发生飞升；内螺纹管内的传热特性在不同焓值区域表现不同，在远离拟临界焓值的低焓值区域和高焓值区域，呈现出相似的规律，而在接近拟临界焓值区域时，传热得到强化。

Limited Class: Socket weld, butt weld or threaded

Thirty cadaveric femurs were randomly allocated into five groups, each with 6 femurs. An osteotomy was made (Pauwels angle 70°) in the middle of the femoral neck. Then each group was fixed using one of these methods:①Dynamic Hip Screw ;②Three 4mm Steinn Pins that placed in accordance with the compressive trabeculae and clingy to the femoral calcar ;③One compressive screw;④Low angle fixation of external fixator;⑤High angle fixation of external fixator.

3取经防腐处理的人尸体股骨30具，随机分成5组，每组6具，在股骨颈中部按Pauwels角70度锯断，每组分别以以下方法固定：①动力髋螺钉固定；②三枚4mm斯氏针按本文第一、第二部分分析出的股骨的主应力方向（按压力骨小梁方向紧贴股骨距低角度倒三角形钻入）固定；③一枚加压螺纹钉固定；④自行设计的外固定支架低角度倒三角形固定；⑤外固定支架按大角度固定。

S where the threaded portion has an extruded rigid "canula" of small diameter. These are used where the areas of application of the product are specifically defined.

2在管口的螺纹部分有一个小直径的挤压硬管，如果产品的使用部位需要特别界定，则适用这种管口。

With certain shapes of or canula, elongated caps are made to cover both canula and threaded portion, and seal the canula at its top.

根据管口和导管的不同形状，可以制造细长的管盖以覆盖导管和螺纹部分，并在顶部封住导管。

With certain shapes of nozzle or canula, elongated caps are made to cover both canula and threaded portion, and seal the canula at its top.

根据管口和导管的不同形状，可以制造细长的管盖以覆盖导管和螺纹部分，并在顶部封住导管。
