查询词典 phase transition

Phase correlation and then reaches image mosaic by graph cut and poisson image fusion.graph cut is used to find a globally optimized seam-line for deghosting while poisson image fusion is used to realize smooth mosaic without exposure difference.a new weight calculation method based on the statistics of guadient direction histogram is presented here in order to robustly realize graph cut.an edge transition poisson image fusion method is also proposed to reach exposure difference removal

该方法在相位校正的基础上将图切割和泊松融合相结合实现拼接，图切割用于搜索全局最优的缝合线以去除鬼影，泊松融合用于曝光差异的处理。本文给出新的基于梯度方向直方图统计的权值计算方法，实现稳定的图切割。另外，本文还设计出重叠过渡的泊松融合方法，较好地完成图像合成。

In our country, with the establishment of economy market and the deepend reform of modern enterprise system , mid-and small-scale enterprise have obtained a certain development in gaining a broad market space and the advantageous policy environment , with the trade , the investment liberalization tide comes turbulently after joins WTO, the internationalization is not only an inevitably choice for mid-and small-scale enterprise for further development , but also has the possibility to be the road of successc Under the background of economy globalization , the velocity of the international industry transition speeds up , in order to realize the different phase goals of "goes out" strategy , needs the enterprise to enlarge invests on the marketing channel design , which enable the enterprise healthy and orderly development.

在我国，随着市场经济的建立和现代企业制度改革的深化，中小企业获得了广阔的市场空间和有利的政策环境，取得了一定的发展。面对加入WTO之后汹涌而来的贸易、投资自由化浪潮，国际化不仅是中小企业进一步发展的必然选择，而且也有可能是一条成功之道。在经济全球化背景下，国际产业转移速度加快，实现"走出去"战略的各阶段性目标，更需要企业加大在营销渠道设计上投入，使企业能健康有序地发展。

A configuration that transition points are reflection symmetric about the midpoint with phase offset in one period is proposed. The intensity of the zero order becomes the function of the phases and can be eliminated.

采用周期内位相突变点镜向对称，前后半周期位相相差结构设计的反对称型达曼光栅，可使其零级衍射光斑强度仅是位相的函数，因此可消除零级谱点。

研究结果表明，Cr12MoV模具钢经电子束表面熔凝处理后的显微组织可以明显地划分为四个区域：表面熔化区、相变硬化区、过渡区及合金的基体。

The thermal behavior of silver behenate has been studied by infrared spectroscopy, X-ray diffraction, combined thermogravimetry-differential thermal analysis-mass spectrometry. The results indicated that complicated phase transitions took place while heating silver behenate,but there were two distinct thermal transitions. During the first transition at 138°C, the alkyl chains of silver behenate were transformed from an ordered into disordered state.

通过采用粉末X射线衍射、红外光谱、热重-差热分析与质谱联用技术，对山嵛酸银纳米晶体的热行为研究发现，山嵛酸银受热发生了一系列相转变，它有两个明显的突变：即在138℃左右，山嵛酸银的烷基链从高度有序转变为无序状态；在231℃左右，山嵛酸银发生了热分解，其主要分解产物为银纳米粒子和山嵛酸。

The structure measurement indicates that only a small amount of Bi3+ ions can not enter the A-site of La2/3Ca1/3MnO3 lattice. Because of the low melting behavior of bismuth oxide, the superfluous Bi will segregate as insulating bismuth oxides and bismuthate. Because of the segregation of Bi, the surface of the main phase has different ferromagnetic property from that of the core, namely the magnetic inhomogeneity of the samples is enhanced, which results in the broader ferromagnetism-paramagnetism transition and magnetoresistance plateaus in samples with the high Bi content.

结构测试表明Bi并不能进入La2/3Ca1/3MnO3的晶格锰位，由于A位元素的过量和铋氧化物的低熔点特性，烧结过程中Bi元素析出形成了绝缘性的第二相；并且Bi的析出导致样品主相的表面存在与主相体心磁性质不同的铁磁相，即样品的磁不均匀性增强，使得高Bi含量的样品表现出宽的铁磁-顺磁转变和磁电阻平台效应。

From these results the mechanism transition phenomenon of a self-pumped phase conjugator between SPB-FWM and TIR can be explained Some factors that affect the backscattering gain coefficient are discussed.

最后，对影响γ〓导致机制转换的因素进行了讨论。

The phase structural change withtemperature of solid helium is also studied using MD simulation at a givendensity 1.6g/cm3.Radial distribution functioncalculation demonstratesthat its second peak will disappear beginning in the region from 2000K to3040K,showing a solid-liquid transition or a decrystallization occurs.

文中进一步用分子动力学方法研究了在固定ρ＝1.60g/cm3下固氦相结构随温度的变化，发现其径向分布函数的第二个峰在2000K到3040K区间及其以后逐步消失，意味着此时发生了一次固-液相变或非晶化过程。

The mathematical model of deflagration to detonation transition for coke p owder and oxygen mixture in one-dimensional closed system was established on th e basis of chemical reaction and two-phase reaction fluid mechanics theory.
