During the operation of the salt cavern gas storage, the salt bed around the salt cavern will generate variation of stresses because of strata pressure and internal pressures of the salt caverns. 盐穴储气库在运行过程中溶腔周围的盐层受到地层压力和溶腔内压的多重作用而产生应力变化。
Thus the surplus accumulation of Na+ in internal body and the secondary water stress induced by NaCl stress are the main causes of salt injury, and PP may be considered as one of the physiological indexes for salt tolerance of sweet potato. 因此,Na~+的积累及次生水分胁迫是导致膜伤害的主要原因,质膜透性可以作为甘薯耐盐性生理参数之一。
Application of Internal Standardization to Rapid Coprecipitation Technique Using APDC-Cu(ⅱ) for FAAS Determination of Lead in Salt 应用内标的APDC-Cu(Ⅱ)快速共沉淀分离富集和原子吸收光谱测定食盐中的铅
A lot of internal and abroad prospecting practices on oil gas and potash salt also have proved their closely relationship, moreover their prospecting means and way are also the same. 国内外大量油气及岩盐钾盐的勘查实践也多次证实了二者之间存在着密切的关系,而且二者的勘查手段和方法一致。
At last through the Internal Audit and the Management Review we increase the Effectiveness of the QMS and make the Nanking salt company pass the QMS registration smoothly. 最后通过内审和管理评审,提高了南京盐业公司质量管理体系的有效性,并使南京盐业公司顺利通过了质量管理体系认证。
The calculation method of a modified equation of the internal pressure salt effect theory 介绍一种改进内压力盐效应公式的计算方法
Internal corrosions of the oil storage tanks are caused by oxygen-absorbed, salt and deposits, the last kind of corrosion is most serious. 原油储罐的内壁腐蚀原因为吸氧腐蚀、盐类腐蚀和原油沉积造成的垢下腐蚀,而且原油沉积造成的垢下腐蚀最严重。
The acoustic internal friction of iron vibrating transversely in a steady magnetic held was measured by means of Rochelle salt ( NaKC_4H_4O_6 · 4H_2O) crystal plates, the frequency of vibration used was 1633 cycles/ sec. 用罗谢耳盐(NaKC4H4O6·4H2O)压电晶片测量铁在稳定磁场中作横振动时的内耗,所用的振动频率是1633周/秒。
A salt can jostle into zeolite internal pores by heating the mixture of the salt and a zeolite even though the salt ion is a little larger than the zeolite channel. 盐类和分子筛混合加热,即使盐类的离子直径比分子筛有效孔径稍大,盐类仍可在分子筛内孔和内表面实现分散。
The rock salt is the best energy storage medium by internationally recognized, and the change of the internal pore network is an important factor in salt rock gas storage leak. Subtle changes will lead to a substantial increase in gas permeability. 盐岩作为国际上公认的能源储存的最理想介质,其内部孔隙网络的改变是盐岩储气库泄露的重要因素之一,细微的变化就会引起气体渗透率的大幅度增加。
