In experiment , it was found that the solubility of cahpo4 could be affected by the temperature of the system , the heating speed , the pressure and the granularity of initial materials easily . so that the growth of hydroxyapatite whisker was affected because of the change of supersaturation 实验中发现，温度、升温速率、 ph 、压力、营养料等都会影响cahpo _ 4的溶解度，从而改变体系的过饱和度，进而影响羟基磷灰石晶须的生长。
Results of experiment show that the reason of strength decreasing of gypsum added with retarders is that the retarders reduce the supersaturation of liquid phase , and makes the crystal grain largen , and pore is followed to worsen , which lead to the strength drop to a large degree 实验结果分析表明：在掺加缓凝剂后石膏硬化体强度下降的原因在于缓凝剂降低了石膏的液相过饱和度，使结晶颗粒变大，使石膏的孔结构恶化，最终导致了宏观强度大幅度下降。
The paper works out the ice crystal spectrum distributing in the different macroscopic and micro - backgroud of the cloud ( ie , the thickness , the temperature and the supersaturation with respect to ice of the nucleation layer ) . this paper also works out the amount of catalyst which is allowed in the cloud nucleation layer according to the different quantity of the supercooled water , the density of the supersaturation of the vapor with respect to ice . simultaneously , the paper discusses the i nfluence of remaining time when seeding artificial ice nucleus in the different ascending - velocity and altitude , and elicits the proper seeding altitude of the catalyst 以此解为依据，得出了不同均流时，人工引入冰核在核化层存留时间，再以此时间作为人工冰核凝华增长时间，求出不同的云宏微观背景(如核化层厚度、温度、冰面过饱和度等)下的冰晶谱分布，经和实际资料比对符合相当好。进而求出核化层中不同过冷水量、冰面过饱和水汽密度下云核化层可允许的催化用量。同时讨论了不同升速，不同高度引入人工冰核时对其存留时间的影响。
Chondroitin sulfate a ( c4s ) , as a kind of endogenetic urinary macromolecule , not only increased the supersaturation of cac2o4 in solution , but also inhibited the two - dimensional growth and aggregation of com crystals . the growth of calcium oxalate crystals was influenced by surface pressure beneath dppc monolayer film . there were some crystals which have the same appearance as com crystals obtained from pure water system when monolayer surface pressure was hold 1 , 10 and 30 mn / m while those growth at 20 mn / m were perfect orderly induced by dppc monolayer 生物大分子c _ 4s作为一种内源性的尿大分子，它不仅从热力学上提高ca ~ ( 2 + )在尿液中存在的浓度，使体系中cac _ 2o _ 4保持较高的相对过饱和度，降低草酸钙结石成核的可能性；而且在晶体生长时，抑制com晶体晶面的二维生长和晶体聚集。
In order to determine the concentration or supersaturation in crystallization process , an online test apparatus was set up based on the relationship between the concentration and the electroconductivity at a temperature for binary electrolyte systems , which was also used in similar fields to measure the electrolyte concentration 根据二元电解质溶液体系的浓度与电导率和温度之间的关系，建立一电导率在线测量装置，可在一定范围内测定溶液的浓度或过饱和度。实验得到与hlozny等人基本一致的溶液电导率变化趋势。
In this article the chelating precipitation method and the converting precipitation method were chosed to synthesis zno nanoparticles on the basis of the theory of synthesis of nanoparticles by precipitation . uniform and dispersed zno nanoparticles were prepared by the two methods because zn2 + of conformation crystal was flee slowly and the supersaturation was well controlled . the problem which zno nanoparticles are wide size and agglomerative was solved 本文根据均相沉淀法合成纳米粒子的原理，采用络合沉淀法和沉淀转化法合成纳米氧化锌。这两种方法利用溶液中的构晶阳离子zn ~ ( 2 + ) ，缓慢地释放出来，有效地控制了溶液中的过饱和度，可以得到粒径均匀、分散的纳米氧化锌，解决现有制备工艺中纳米氧化锌粒径分布宽、易团聚的问题。
Substituted by a densimeter based on the archimedes laws , the online concentration measurement was further modified , and the quality of the measured data was improved with satisfactory accuracy and repeatability . nevertheless , information obtained from the continuous phase ( concentration or supersaturation measurements ) was still not enough to completely define the system 为此，本文基于阿基米德定律，采用密度法改进了实验装置，实现了对结晶过程中溶液浓度或过饱和度的连续在线测量，并提高了测定精度，所测得实验数据具有较好的重现性。
It ' s pointed out that , under the condition of vim refining , the amount of oxide inclusions residue in molten steel increases with the increased loss of deoxidizing elements , and the key of melting extra - low oxygen steel is to avoid the thermal decomposition of lining material ; the size of deoxidizing products increases with the increased degree of supersaturation of deoxidizing elements ; larger inclusions granules found in extra - low oxygen steel come mainly from lining material 结果表明，在真空感应熔炼条件下，残留在钢中的氧化物夹杂数量随脱氧元素铝烧损量增加而增加，熔炼超低氧钢的关键是避免炉衬热分解；脱氧产物尺寸随脱氧元素过饱和度增加而增加；超低氧钢的大颗粒夹杂主要来自炉衬材料。
And considerable work has been done hi the growth behaviour in the tetrachloride solution concluding studies of crystal growth and growth kinetics . a crystal of dimensions 20mm x 20mm x 1mm was produced hi the tetrachloride solution by lowing temperature . and bcf spiral growth mechanism for the surface diffusion model was analyzed using the kinetic data 本文以苯为溶剂溶液降温法培养出了60mm 40mm 3mm大尺寸hhm单晶；另外探讨了hhm在四氯化碳溶液中的生长行为，溶液降温法培养出了20mm 20mm 1mm的较大尺寸单晶，并用动态循环体视显微镜观察法测定了其在不同的过饱和下主要显露晶面的法向生长速率，在较大过饱和度范围内考察了其bcf表面扩散螺位错生长机制。
