查询词典 permeable

Cake properties such as cake thickness, toughness, slickness and permeability are important because the cake that forms on permeable zones in the wellbore can cause stuck pipe and other drilling problems.

泉水很干净，因为是由具有渗透性的岩石过滤的。

These work are mainly based on two assumptions: one is called as the Deeg-Pak assumption, i.e., the crack is assumed to be an impermeable slit and thus the electric field inside the crack is equal to be zero; the other is called as the Parton assumption, i.e., a crack is treated as a permeable cut across that both the normal components of electric displacement and the tangential component of electric field are continuous.

裂纹问题：对于压电介质内的裂纹问题，近十年来人们已做了大量的理论分析工作，这些工作主要是基于两种假设：一种称之为 Deeg-Pak 假设，即假设裂纹为电非渗透的，因此裂纹内的电场等于零；另一种称之为 Parton 假设，即假设裂纹为电渗透的，且跨越裂纹上下表面电位移的法向分量和电场的切向分量是连续的。

Sift the anther s onto unglazed, permeable paper, such as newspaper or paper toweling, for drying

将花药筛到无光的、具渗透性的纸上，如报纸或卫生纸，以便花药干燥。

Sift the anthers onto unglazed, permeable paper, such as newspaper or paper toweling, for drying

将花药筛到无光的、具渗透性的纸上，如报纸或卫生纸，以便花药干燥。

But the data analysis is relied on experience and statistics in a certain extent, so sometimes it makes big errors. Daniudi gas field is a low permeable gas field, the pressure buildup slowly. The measured formation static pressure is low and the flow pressure is high, so the calculated unresisted flow is high.

特别是大牛地气田属于低渗透气藏，压力恢复缓慢，所测的地层静压值偏低，求产开井3天以上多数井测取不到稳定的流压，所取流压值偏高，计算的无阻流量均偏高。

Inthe last stage of reduction,the iron substrates formed on the surface of Wüstite areporous and permeable to gaseous diffusion.The reduction rate is controlled by thesurface reaction on the Wüstite-iron interface,but the rate of this surface reactionis limited by the velocity of CO formation.

在浮士体还原成金属铁的阶段，所生成的多孔性金属铁并不阻碍气相的扩散；还原的速率由浮士休-金属铁相界面的表面反应所控制，而表面反应的速率则受CO的生长速率所限制。

Moisture vapour permeable, 100 % waterproof and 100 % windproof

市场创新：无孔的薄膜，100%防水、防风且透气。

This might be because large breasts signal a good supply of oestrogen, and one effect of oestrogen is to make more permeable the zona pellucida, the membrane of the egg.

这种本能差不多和之前是相同的，它同样定义了乳房，而且基于对这样被定义了的东西的评估加入了一种情绪，一种和性欲有关的情绪。

A new technique for selective plugging and acidizing oil wells is presented based on the principle of temporary plugging and acidizing in which selective plugging agent is first injected to block high permeable zones, then acid is injected to acidize low perlmeable and contaminated ones.

针对暂堵酸化技术存在的问题，提出了一种油井选堵酸化的新技术，即在注酸前注入选堵剂封堵高渗透水层，然后注入酸液以酸化低渗透层和污阻部位。研制了符合最终堵水不堵油要求的选堵剂，描述了这一新技术的机理。通过模拟试验，考察了新型选堵剂的选堵效果、封堵强度及酸化转向率等。
