例句与用法

It has been found that all the elements in the addition act respectively in the way that affect the material ' s properties during the calcining process and the increase of the pms / pzn ratio can weaken the stability of the crystal structure of the sintered ceramics and cause the crystal structure transformation from the tetragonal to the rhombohedral as well
发现多元压电陶瓷材料中，无论是主加组元还是微量掺杂，预烧阶段，它们在陶瓷中的作用都表现为单独离子对陶瓷结构和性能所起的作用。烧结后，随着pms pzn相对量的提高，陶瓷晶体结构由四方相向三方相转化，同时稳定性下降。
The appropriate calcinations temperature is about 700 , and the tetragonal sno2 phase crystal structure of the particles remained unchanged when sb was doped to it . as the calcinations temperature increasing and the calcinations time prolong , the size of particles grows and the crystallization tend to be complete . study on the electrical properties of ato powders prepared by hydrothermal synthesis was performed in - depth , the most optimal electrical properties are obtained at doping ratio of 11 percent
水热法制备的ato纳米粉体在热处理温度700左右较为适宜，锑的掺杂并未改变粉体的四方相金红石结构，随锑掺杂量的增加，粉体的粒度变小；随热处理温度的升高和热处理时间的延长， ato粉体的粒度增大，晶体结构趋于完整。
The results indicate that the osc and reductibility of the ceo2 - zro2 solid solution are not improved after adding e ions . while after incorporating m ions into the ceo2 - zro2 , the samples exhibit high osc probably by reason that m - o itself also has good capability of oxygen adsorption . after aged at high temperature , the osc of these samples decreased dramatically for the formation of m2o3 and mo2 and for the separation of tetragonal phase of ceo2 - zro2
在ceo _ 2 - zro _ 2固溶体中引入m后，由于m - o本身具有氧吸附性能，使得样品表现出很好的储氧能力，但经过高温老化后，原四方晶相的ceo _ 2 - zro _ 2固溶体发生了相分离，且生成了大量的m _ 2o _ 3和mo _ 2相，使得样品的储氧量急剧减少，可还原性能明显降低。
The major composition of crystals is calcium oxalate , it crystallizes with very different crystallization kinetics , e . g . monodinic monolydrate ( com ) , tetragonal dihydtate ( cod ) and triclinic trihydrate ( cot ) . com is easy to form urinary stones because it has stronger affinity for renal tubule cell membranes than cod , cot
其中，晶体的主要成分是草酸钙，主要有三种类型：一水草酸钙( com ，单斜晶系) ，二水草酸钙( cod ，四方晶系) ，三水草酸钙( cot ，三斜晶系) ，其中com与肾小管表皮细胞黏附力最强，是草酸钙型尿结石的主要成分。
The influence that the zr / ti ratios have on the ceramic crystal structure and its properties are studied through the research carried out about the relative respects of the fabricated samples . the increase of zr / ti ratio can result in the crystal structure transformation from the tetragonal to the rhombohedral , it can also induce the weakness in the stability of the ceramic crystal structure , for example , the drop in the curie temperature . in order to enhance the relative low mechanical quality factor of pzn - pzt system piezoceramics , component addition pb ( mn1 / 3sb2 / 3 ) o3 ( hereafter abbreviated as pms ) are introduced in to form a new psudo - tetragonal system ceramics
为获得具有高的机电耦合系数kp ，高的机械品质因数qm的高性能压电陶瓷，采用二次合成法制备了不同zr ti比的铌锌酸铅-锆钛酸铅基( pzn - pzt )三元系压电陶瓷材料，研究了zr ti比变化对陶瓷结构和性能的影响规律，发现zr ti比增大除了可以使陶瓷的相结构由四方相向三方相转化外，还降低了陶瓷的结构的稳定性，使tc温度下降。
