Salt Dome is a mushroom-shaped or plug-shaped diapir made of salt , commonly having an overlying cap rock .

盐丘是褶曲的平面形态中浑圆形褶曲的一种,穹隆构造,其核部为很厚的岩盐层,并刺穿上覆岩层,此种穹隆称为盐丘

Aiming at these problems, we have designed the processing workflow to effectively suppress the surface Wave interference, regular interference, high energy interference, and other random noise interference. The treatment clue was from thick to thin. Firstly, the spectral analysis method was used to establish macroscopic velocity field. Then, the ray tomography method was used to enhance the accuracy of velocity analysis and to establish a more accurate velocity model. Finally, the finite difference pre-stack depth migration on method in -k domain was adopted to solve the imaging problem of subsalt and salt dome flank.

通过合理组织处理流程,有效压制了面波干扰、规则于扰、强能量干扰和随机噪声干扰;采用由粗到细的思路,先利用谱分析方法建立宏现速度场,再利用射线层析成像方法提高速度分析精度,建立了较为准确的速度模型;利用频率-空间域有限差分叠前深度偏移解决了盐下及盐丘侧翼的成像问题。

A new family of sulfonate surfactants, in which the sulfonyl group is attached to one of the alkyl chains, has gained interest owing to their biodegradability, low sensitivity to water hardness, foaming ability, and lower skin irritability than the conventional alkylbenzene sulfonate.

一个新家庭的盐表面活性剂,sulfonyl集团隶属于链条之一,已获得利息烷基是由于它们生物降解性、低敏感性对储层水硬度、发泡能力和较低的皮肤过敏性比传统的烷基苯磺酸盐黄。

磷钼杂多酸和聚二茂铁硅烷多层组装膜修饰电极及其电化学行为采用层层组装法在金电极上组装多金属氧酸盐阴离子和聚阳离子聚二茂铁硅烷,交替沉积多层膜,构建了杂多酸-PFS多层膜修饰的金电极。

A kind of high speed sulphamate nickel-based electrolyte is chosen as basal electrolyte, the influences of plating process parameters on the micro-hardness of the nickel deposit have been studied by orthogonal experiments. It is concluded that the main influence factors on the micro-hardness of the nickel deposit are sulphamate concentration and electrolyte temperature, the deposition rate and quality in single-pulse mode are higher than that in DC power and double-pulse mode.

选择以氨磺酸型高速镀镍液作为基础镀液,通过正交试验研究了电镀工艺规范对镀层显微硬度的影响关系,试验结果表明:镀液主盐氨基磺酸镍浓度和镀液温度是影响镀层硬度的显著因素,单脉冲供电模式下的电镀沉积速率和镀层质量优于直流和双脉冲模式。

Oxalic acid loading substantially stimulated soil P release from A1 horizon, showing a linear relationship; but its effect on B horizon soil was relatively negligible, especially at low oxalic acid concentrations mmol L^(-1. Oxalate solutions 0.5~20.0 mmol L^(-1 oxalic acid adjusted to pH 5.16 with 10.0 mmol L^(-1) NaOH had a much higher (1.51~2.98 times) soil-P-release effect than oxalic acid solution the same in oxalate concentration. Therefore, the mechanism of oxalic acid/oxalate triggering release of soil phosphorus is assumed to be dominated by ligand-exchange or complexing reactions of oxalate anionC2O(superscript 2- subscript 4 but not simply acid-dissolving effect. The effect of oxalate anion on soil phosphorus release was found to be somewhat cumulative, i.e. the amount of P released was primarily controlled by the cumulative oxalate loading rate, relatively independent of the manner of oxalate addition (one-time or sequential).

结果表明,草酸能显著促进暗棕壤A层磷的释放,土壤磷溶出量随草酸溶液浓度升高而线性增加;但对B层土壤磷的释放效应相对较弱,草酸浓度低於5mmolL^(-1)时B层磷的释放不明显。pH5.16草酸钠溶液比相同浓度的草酸溶液具有更高的解磷效率,在设置二者浓度为0.5~20.0mmolL^(-1)时,前者的解磷量是后者的1.51~2.98倍,推断草酸盐溶液或凋落物淋洗液中草酸类物质促进暗棕壤磷释放的主要机理在於草酸阴离子C2O(上标 2-下标 4配位反应。
