Self-Exciting Mode Oscillating-Flow Heat Pipe, also called pulsating heat pipe or oscillating heat pipe, is a novel heat transfer device that has an excellent heat transport performance.

自激振荡流热管也称为脉动热管，是一种新型高效的传热元件。本文提出了采用脉冲加热代替常规连续热源加热强化自激振荡流热管传热的方法，并对其进行了实验研究。

The VCL method and the displacement method are used to calculate the Stress Intensity Factors of semi-elliptical surface crack at the root of pipe screws, on the basis of which a simplified calculating model for screws contact is put forward so as to analyse the fracture intensity for oil drill pipe screw coupling. For the semi-elliptical surface crack with different shape and deep ratio at the root of female and male screws and the corner of male flange, the SIF has been studied systemically under inter-pressure, tension, bend and torsion loads and the approximate formulas encluding the structure parameters of oil drill pipe screw coupling, deep ratio and the shape parameters of surface crack are developed.

对工程实际中的多种石油钻杆接头螺纹连接件，就公螺纹齿根、母螺纹齿根、公螺纹台阶转角处存在的不同形状、不同厚度比的半椭圆表面裂纹，在拉伸、内压、弯曲、扭转多种载荷作用下的应力强度因子作了系统研究，在大量有限元计算基础上，建立了包含接头结构参数、裂纹形状、厚度比在内的近似计算公式。

In the light of geological characteristics of Dongfang 1-1 Gas Field, mass indoor experiments are conducted and studied. Sand grain level are analyzed, the sand control parameters and screen pipe and blind pipe combination proportion is optimized. On this basis, the most suitable horizontal screen pipe sand control method for this gas field is found. Through the medium of DONGFANG 1—1 gas field field conduct proven, the sand control technology are completely run up to DONGFANG 1-1 gas field completion require.

针对东方1—1气田的具体地质特征，通过大量的室内实验研究，对地层砂粒度进行了分析和分选性研究，对防砂参数和筛管与盲管的组合比例进行了优化，从而找出最适合该气田的水平井筛管防砂完井方法，通过东方1—1气田的现场实施证明，该防砂技术完全达到了东方1-1气田完井的要求。

Pipe vs. resonance chamber: Limited by the industrial design, it is hard to set microphone near the surface of the case. Therefore we use a pipe to lead the sound, but the frequency response might loss if the length of pipe is too long or the volume is too big.

导音管vs。音腔大小因为ID的问题，麦克风的安装位置往往不能贴近机壳的表面，会以导音管的方式导入声音，但太长或是容积太大的导音管会使频响不平。
