查询词典 phases

Children go through dynamic phases of growth, and a low-calorie diet is not what they need.

他们需要的是营养和运动。

It is found that, compared with the vacuum sintering, the magnet sintering at argon protection has lower density, magnetic-energy product and remanence, but coerciveforces are higher. The magnet has more and bigger pores, and there obviously exist loose microstructure, the Nd-rich phases are clearly distributed along the grain boundaries mainly in the shape of lumpish and lamelliform.

研究发现，与真空烧结相比，采用Ar保护烧结时磁体的密度、磁能积和剩磁相对较低，矫顽力较高，磁体中形成的孔洞较多，孔径较大，并有明显的显微缩松存在，富Nd相的数量明显较多，且主要呈块状和片状沿晶界分布。

Using of optical microscopy, X-ray diffraction, transmission electron microscopy, hardness and tensile testing, the effect of thermal exposure at high temperatures on the microstructures and of high-temperature tensile properties of rapidly solidified AlCrYZr have been studied. The results show that there are two main phases,Al20Cr2Y(cubic, a=1.437 nm) and DO23Al3Zr(terganal, a=0.4 013 nm , c= 1.732 nm), in the as-solidified alloy. The Al20Cr2Y phase can maintain its cubic structure at 500℃, but the particles coarsen remarkably and even become lumpish. In coarse lumpish Al20Cr2Y phase the plane faults and twin structures exist.

摘 要：采用金相、 X射线衍射、透射电镜、硬度测定和拉伸试验研究了高温热暴露对快速凝固AlCrYZr合金显微组织影响和高温下力学性能的热稳定性，结果表明，快速凝固AlCrYZr合金主要第二相为Al20Cr2Y(立方，a=1.437nm)和DO23Al3Zr(正方，a=0.401 3nm， c=1.732nm)，Al20Cr2Y在500℃热暴露尚能保持其立方结构，但质点明显粗化，甚至块状化，在粗大的Al20Cr2Y相中存在有层错和孪晶结构。

Level down to the minimum weight began to rise after two or three days after the restoration of calm, the period known as the magnetic storm recovery phases.

水平分量下降到极小值之后开始回升，两三天后恢复平静，这段期间称为磁暴恢复相。

Contents of calcium, phosphorus and potassium in the mallard eggshell at different hatching phases were measured.

野鸭卵的正常发育不仅取决于孵化条件，卵内营养物质转化和利用也起着重要作用。

According to the method of developing a software project,the thesis mainly discussed the study and design of the Auto-metering Management Software System in four phases:design of database;design of man-machine conversation;design of communication and realization of its emluator;design of integrated management of the system.

本文按照开发软件工程项目的思路，主要从以下四个方面详细论述了自动抄表管理软件系统的研究和设计：数据库的设计、人机交互界面的设计、通讯模块的设计及通讯仿真的实现、系统综合管理模块的设计。

Wherever pluralistic philosophy distinguishes a multiplicity of things, Monism denies that the manifoldness is real, and holds that the apparently many are phases, or phenomena, of a one.

无论多元化的哲学区别於众多的事情，一元否认manifoldness是真实的，并认为显然许多阶段，或现象，对一个。

I think that with our selection of 16 sonatas we have covered three important creative periods in the life of an already mature composer: the Mannheim period and the two phases of his time in Vienna.

我想，我们用选出的十六首奏鸣曲覆盖一个成熟作曲家的三个重要创作期：曼海姆时期和两个维也纳阶段。

The results indicate that both structure and properties of martensite and ferrite phases are quite different from those of single-phase ones.

本文研究了经亚温淬火获得的铁素体-马氏体双相20钢的组织性能关系以及冷轧时的形变行为。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
