查询词典 precipitates

At high CaCl_2 concentration, when the product of the free Ca~(2+) ion concentration in solution and the monomer surfactant concentration exceeds the solubility product of Ca_2 salt, Ca_2 precipitates can be salted out in this system.

在较高的CaCl_2浓度下，溶液中游离的Ca~(2+)离子浓度与表面活性剂单体浓度的乘积超出Ca_2的溶度积时，体系中会析出Ca_2沉淀。

Some data about apparent solubility product of Mo and Zr precipitates have been determined in 1.0, 2.0, and 3.0 mol/L HNO 3 solutions. The effects of different concentration of nitric acid and initial concentration of Mo and Zr on the apparent solubility product are also investigated.

实验还测定了 1 0 ，2 0 ，3 0mol/L硝酸溶液中钼锆沉淀的表观溶度积K′sp，讨论了硝酸浓度、钼锆初始浓度对表观溶度积的影响。

We have observed the structure of these dune sands and analyzed the grain-size,surface textural features and several main chemical elements of them,the results showed that:(1) these dune sands have some eolian structure characteristics which are similar to the recent dune sands;(2) they are also similar to the recent dune sands in grain-size components,and parameters of Mz,?滓,Sk and Kg,as well as in several main chemical components;(3) the scatter plots of Mz-?滓,SiO2-Al2O3+TOFE and the probability curves of grain-size showed that these paleo dune sands are different from paleosols and fluvio-lacustrine facies but are consistency with recent dune sands;and(4) the quartz sands have well roundness and some surface textural features such as dish-shape pits,crescent-shape pits,pockmarked pits,upturned cleavage plates,siliceous precipitates and siliceous crevasses,indicating that they had been carried for a long time by the wind.

对这些沙丘砂的沉积构造观察以及粒度、扫描电镜和常量化学元素分析结果表明：(1)这些沙丘砂具有与现代沙丘砂相似的风成沉积构造特征；(2)粒度及其参数--Mz、σ、Sk和Kg，以及主要化学组分SiO2、Al2O3和TOFE也与现代沙丘砂相近；(3)Mz-σ、SiO2-Al2O3+TOFE散点图和概率累积曲线显示这些沙丘砂与萨拉乌苏组中的河湖相、古土壤差别明显，而与现代沙丘砂一致；(4)石英砂颗粒具有良好的磨圆以及碟形坑、新月形坑、麻坑、上翻解理薄片、硅质沉淀和硅质裂纹等表面结构特征，反映其曾受持久的风力搬运作用。

Based on the study of 1420 Al-Li alloy strengthened by a single precipitate, the author study strengthening contributions and their anisotropies of each phase and that of deformed textures to anisotropy in 2090 and 2090+Ce alloys strengthened by two precipitates, by reversion treatment and the exponential additional rule.

在研究单相强化的1420合金的基础上，通过回溶处理和指数叠加法研究了两相强化的2090及2090+Ce合金中各析出相对合金的强化贡献及其各向异性、形变织构对合金各向异性的贡献。

Therefore the diffusional rate increases, and the coarsing rate of the precipitates raises as well.

本文开创性地研究了原始颗粒边界析出对热等静压压坯断裂的作用。

Be in early period of age the Warring States, namely today on city of chaste tree state's located river Chinese Campagna arisen the Hunan country with powerful and prosperous rich and popular, the fertile soil that ancient Yun Mengze precipitates, chinese, 3 rivers collect chaste tree, Hunan the wisdom that connect, advantaged geographical and natural condition, make age 5 bully with the Warring States 7 hero all dare not covet, reason comes when a large number of heroes of absorb of the Qin Dynasty, still have " Chu Shengsan door, die the hearsay of Qin Bichu ".

早在春秋战国时期，即今荆州市所处的江汉平原上就兴起了富庶强大的楚国，古云梦泽沉淀的沃壤，汉、荆、湘三江汇通的聪明，得天独厚的地理自然条件，使春秋五霸和战国七雄均不敢觊觎，故至秦并吞群雄时，尚有&楚剩三户，亡秦必楚&的传言。

The big eared hedgehog, the little owl, the sand gecko, the three-toed jerboa, and every show needs a villain - saw-scale - the viper!

大耳刺猬，小猫头鹰，沙壁虎，三趾跳鼠，每场戏都需要反派角色：蝰蛇。
