查询词典 phase transition

This technique uses a spiral phase plate with a small central aperture placed on the Fourier plane of so imaging system. If the spiral phase filter is rotated by a certain angle around its central axis, a phase shift between the zero-order spatial frequency component and the remaining of the object is produced, and the magnitude of this phase shift is proportional to the rotation angle. Using this property, we can record a sequence of intensity distribution of the output beams corresponding to different rotation angles, and then digitally reconstruct the objects by using a phase-shifting algorithm. Both the theoretical analysis and simulation experiment results demonstrate the feasibility of this approach.

Furfur. At the same time, selected the culture supernatant. Used the whole-fat-cow"s-milk plate method, the Folin-phenol method and the QuantiCleave proteinase Assay Kit to test the proteinase activity of mycelial phase and yeast phase of M. furfur. The effect of temperature and pH on this assay was also evaluated.Result:①The whole-fat-cow"s-milk plate method: Seven days after inoculation, the proteinase activity of the mycelial phase supernatant (12.5 ± 1.2mm) is higher than that of the yeast phase (9.25±0.71mm)(p.05); With the passage of the inoculation time, the proteinase activity of the mycelial phase is rising; the temperature has no obvious effect on the proteinase

At the begin phase of PM, especial bid time, competition is strong, so competitive intelligence activity is main activity in this phase ; general information management is main information activity in project impletion phase; project information pigeonhole is main information activity in project finish phase, IT application is important in this phase.

在项目开始阶段，特别是投标时，竞争性较强，需要竞争情报的支持，这个阶段主是竞争情报的活动；而项目实施阶段的信息活动是一般的信息管理活动过程；结束阶段，是项目信息的归档管理，在这阶段强调信息技术在其中的应用。

The results obtained by XRD show that the as-cast and quenched alloys have a multiphase structure, including theNi3 phase, LaNi5 phase and LaNi2 phase. The substitution of Al for Ni increases the amount of LaNi2 phase in the as-cast alloys, but it has an inappreciable influence on the abundance of the LaNi2 phase in the as-quenched alloy.

X射线衍射分析结果表明：铸态及快淬态合金具有多相结构，包括Ni3相、 LaNi5相和一定量的LaNi2相； Al替代使铸态合金中LaNi2相的量显著增加，但对快淬态合金中LaNi2相的相丰度影响不显著。

Paradise fish has regular and ritual process of agonistic interaction which can be separated into three phases, namely, initial phase, threatening phase, and fighting phase. In initial phase, two fish encounter and swim close to each other. In threatening phase, two fish display shaking, head-tail swimming to threat their opponent.

目前已知敌对行为牵涉到中枢神经系统的调控，尤以中枢神经系统中的血清张力素神经元被许多研究学者指出是与敌对行为调控相关，但尚未确定血清张力素神经元在动物进行敌对行为过程中是如何的参与其中调控。

The phase-locked loop method of random phase angles is put forward, by which the sinusoidal quantity of random phase angles can be calculated, and phase leading can be realized and locked at random phase angles.

根据电网和普通负载的特点，提出了基于相位超前的孤岛效应检测方法，详细分析了这种方法的工作原理，最后进行了实验验证。

Moreover, there exists a morphotropic phase boundary for the composition at x= 0.33 , and the rhombohedra phase and tetragonal phase coexists for the composi tion near MPB, but the pure rhombohedra phase and tetragonal phase separately exists for the composition away from MPB.

In phase one, the suspended liquid from semicontinuous slurry microcosms was used as an inoculum in CSTR. In phase two, the effluent of column experiment was used as an inoculum in CSTR. The purpose of two phases is to find out the correlation between environment factors and toluene-utilizing bacteria community for each phase, and to compare with the correlation between phase one and phase two.

混合连续流实验依菌种来源不同分为两阶段进行，第一阶段利用半连续培养泥浆法血清瓶中的悬浮菌液作为菌种来源；第二阶段则是利用管柱试验之出流液作为菌种来源，比较及观察两阶段反应器内的环境因子与甲苯分解菌社会结构的关联性。

The comparative investigation of the characteristics of deformation and AE were conducted and the results are presented as followed: 1. The characteristics of rock AE are correlated to the strength, joints, cracks, and the size and hardness of crystalline grain. 2. The sequence of AE can be divided into four phases: beginning phase, tempestuousness phase, drop phase and dreariness phase. The loss and the duration of the phases are correlated to the rock character and flaws in the rock. 3. The AE rate characteristics are not almost concordant with the AE energy rate. 4. Besides the homogeneity, the strength of rock contributes the activity of AE. The higher the strength is, the lower the activity is. 5. There is a dreariness phase before the failure of most kinds of rock. 6. Whether the precursor is obvious is correlated to rock the character, and the precursor of AE rate is more apparent than the precursor of AE energy rate comparatively.

通过对比研究这六种不同岩石的变形和声发射特征发现，岩石声发射受到岩石强度、节理裂隙和晶粒软硬大小等的影响；岩石声发射过程存在初始区、剧烈区、下降区和沉寂区，各个阶段是否存在及持续时间与岩石强度、内部缺陷等有关；岩石的声发射事件率特征与能量率特征并不完全一致；岩石的声发射活性除了受其均匀性影响外，还受到岩石的强度影响，强度越小，声发射活性越强；大多数岩石破坏前存在一声发射沉寂区；岩石的破坏前兆是否明显跟岩性有关，相比较而言，岩石破坏时的声发射率前兆比声发射能量率前兆更为明显一些。
