White clay is a mild clay which soothes and softens the skin and is suitable for all skin types, especially young and sensitive or mature and delicate skins.
白泥是极其温和的，用于舒缓和软化皮肤，适合所有皮肤类型，尤其是年轻敏感皮肤或是成熟脆弱的皮肤。
On the base of the geology engineering characteristic, a large number of laboratory and field investigations have been done, from the clay minerals, solid-phase intrusive, aqueous phase trapping, stress-sensitive and so on factors the lost circulation formation damage mechanism are systematic analyzed, the thinking is put forward to controlling formation lost circulation by the use of temporary sealing technology.
论文以川西新场及大邑地区深层裂缝性致密砂岩气层为研究对象，以形成保护储层的漏失控制技术为最终研究目标，结合工区储层地质特征，开展了大量室内实验和现场调研，从粘土矿物、固相侵入、液相圈闭、应力敏感等方面系统地分析了工区漏失性储层的损害机理，提出了利用暂堵性堵漏控制储层漏失的新思路。
Based on the geological laboratory analysis chemical examinationmethod, to characteristic and so on lithological character, granularity and sedimentary structure has made the multianalysis, West the Qaidam Basin firewood in the local tertiary period evolution deposition big environment, subdivides the N_1 oil depositthe deposition and micro resembling, the union bore logcharacteristic, found has been advantageous brings; With the aid of the core sample observation, the thin slice appraisal, analysis result and so on clay mineral X diffraction, scanningelectricity mirror, has determined the N_1 oil deposit reservoirdiagenesis type, the stage and the sensitive characteristic.
依据地质实验室分析化验手段，对岩性、粒度和沉积构造等特性作了详细分析，在柴达木盆地柴西地区第三纪湖盆演化的沉积大环境中，细分出N_1油藏的沉积亚相和微相类型，结合测井曲线特征，找到了有利的相带；并借助岩心观察、薄片鉴定、粘土矿物X衍射、扫描电镜等分析结果，确定了N_1油藏储层成岩作用类型、阶段和敏感性特征。
Radiation Synthesis and Properties of Temperature-and pH-sensitive P (NIPA-co-AA)/Clay Hydrogels
温度和pH敏感P（NIPA-co-AA）/粘土复合水凝胶的辐射制备与表征
In coalfield exploration in Runan County of Henan Province, thickness of tertiary and quaternary formation is up to 700 m, water sensitive clay, sandy clay, sandy argillite, aleurolite and gravel strata are often encountered. These easily cause hole diameter's shortage or enlargement, wall of hole collapsing and breaking.
在河南省驻马店汝南县林楼一正阳县张楼一带的煤田勘探中，第三、第四系地层厚达700m，经常遇到水敏性粘土、砂质粘土、砂质泥岩、粉砂岩和卵砾石等地层，易造成缩径、超径、坍塌和掉块等孔内复杂情况。
Considering the disturbing of the soil during the pile-sinking, the concept of the soil sensitive was introduced and also the recommendatory value of the soil sensitive for the clay layers in Shanghai area was presented.
考虑到沉桩过程中土体被扰动，公式中引入了土体灵敏度的概念，并给出了上海地区常见粘性土层的土体灵敏度推荐值。
High value such as 20% shown by some tests for sensitive clay is related to the high value of ratio of secondary compression index to compression index caused by soil structure collapse.
试验中所得到的高达20%的数值与灵敏性土在结构破损明显阶段所具有较高的压缩指数与次压缩指数的比值有关。
By this technique, a new understanding is obtained from studies on secondary reworks of oil beds and acidization mechanism, from which the most sensitive mineral for acidization is feldspar rather than clay.
利用这种方法，在油层改造及酸化机理研究中取得了新的认识&酸化最敏感矿物为长石而不是粘土。
Based on the dynamic simulation test of natural core, the influence of the salinity and pH value of water-sensitive strata on clay mineral expansion, disgregation, and migration in the development of oil-gas field is systematically analyzed.
采用天然岩心的动态模拟试验，系统地分析了油气田开发过程中水敏性地层的矿化度和酸碱度对黏土矿物膨胀、分散和运移的影响；
