This paper introduces some concrete measures, based on the concrete problems during the designing, when the net level length of the underground gas pipeline with different subjects is not long enough and the construction methods when the gas pipeline through the heavy caliber road culverts; meanwhile, some plans about the gas meter in middle or small public building users are put up.

5,1},the simplest nontrivial fuzzy lattice,a lot of topological properties of all level spaces and underlying space of the fuzzy real line (R(L),δ) has been discussed by establishing an order-isomorphism between (R(L),δ) and the subset X_L={(r,s)|r≤s,r,s∈R} of R~2.
对最简单的非平凡F格L={0,0 5,1},通过建立L-模糊实直线(R(L),δ)的承载R(L)与平面R2的子集XL={(r,s)|r≤s,r,s∈R}之间的序同构,研究了(R(L),δ)的所有水平空间和底空间的各种拓扑性质。
Based on the combination of numerical simulation and simulated experiments, the effect of foam quality, annulus eccentricity, rotation of drilling pipe, and other factors on the flow properties and cuttings transport ability of foam fluid are studied with foam fluid flowing in annulus of horizontal wells.
本文利用数值模拟方法,结合物理模拟试验,研究了泡沫流体在水平环空流动过程中,泡沫特征值、环空偏心度、钻杆旋转等因素对泡沫流动性能以及泡沫携岩性能的影响规律。
