2) low permeability
低渗透性
1.
Aiming at the occurrence condition of soft coal seam with high gas and low permeability,we build a dynamic model for coal seam deformation and gas migration through theoretical analysis and study the characteristic of Non-Darcy flow of the gas seepage in coal seams.
针对高瓦斯、低渗透性松软煤层的赋存条件,通过相关力学理论研究,建立了煤层变形与瓦斯运移耦合的动力学模型,研究了当煤层变形时,瓦斯气体在孔隙内非Darcy渗流的特点,并引入了非Darcy流β因子和加速度系数2个参量,有效地揭示了煤层瓦斯运移规律的客观本质。

补充资料：低促性腺激素性性功能低下
低促性腺激素性性功能低下
指女孩由于缺乏促性腺激素释放激素(GnRH)分泌，使促卵泡素(FSH)和黄体生成素(LH)分泌不足所引起的性征不发育。其原因可能为中枢神经系统疾病，如感染损伤，肿瘤，或先天缺陷；可能为单一促性腺激素缺乏，特发垂体功能低下矮小症，功能性促性腺激素缺乏等。
