Condensation (cooling) contraction: Blazing volcanic eruption material volume shrinkage, form an arcuate, concentric contraction joint by condensation (cooling) systolic function, the most typical is the perlite pearl structure (Fig.1_A ).
The volatile emission effect: Volatile component of the volcanic eruption substances must escape and form of beaded, irregular pore structure due of the reduced pressure, condensation, volume shrinkage(Fig.1_ B ), This is main formation function of volcanic primary porosity.

Annealing Temperature Effect of PbZr0.4Ti0.6O3 Film on La1/2Sr1/2CoO3 Bottom Electrode Jai-Hyun Kim 1, Kyung Shin Koh 2 and Woong Kil Choo 1 1 Department of Material Science and Engineering, KAIST, 373-1 Gusong-Dong, Yusong-Gu, Taejon, Korea, 2 Department of Chemistry, Chungang University, 221 Heuksuk-Dong, Tongjak-Gu, Seoul, Korea Keywords: Sol-Gel processes, X-ray methods, Ferroelectric properties, PZT, LSCO Abstract.
The crystal structure of the deposited LSCO layer was checked by X-ray diffraction(XRD).
Also the PZT on LSCO was grown along the (001) and (110) orientation in coincidence with that of LSCO, because the crystal structure of PZT and LSCO is both perovskites.

Synthesis and Properties Study of 1-(2,4-dimethoxyl-5-pyrimidinyl)-2-[2-methyl-5-(2-chlorophenyl)-3-thieny-l]perfluorocyclopentene Jingjing Liu, Hongjing Jia and Shouzhi Pu* Jiangxi Key Laboratory of Organic Chemistry, Jiangxi Science and Technology Normal University Nanchang 330013, P.R.China pushouzhi@tsinghua.org.cn Keywords: Diarylethene, Pyrimidine, Photochromism, Fluorescence, Optical storage recording Abstract.
The structures of diarylethenes 1o were confirmed by 1H NMR (400 MHz, CDCl3, TMS): δ 2.09 (s, 3H, -CH3), 3.76 (s, 3H, -OCH3), 3.44 (s, 3H, -OCH3), 7.22 (s, 1H, thiophene-H), 7.28-7.30 (m, 2H, benzene-H), 7.45-7.48 (m, 2H, benzene-H), 8.33 (s, 1H, pyrimidine-H).
The significant difference in absorption bands of the closed-ring isomers compared to their open-ring isomers is mainly due to the increase in π conjugation, which dramatically changes the electronic structure as a whole in such a way that new electronic transitions are observed in the visible region [12,13].

Because both ends of the suspended pipeline is not get collapse soil support, the pipeline can be regarded as beam structure which get elastic support at both ends of the pipe [2].
Peak stress is the maximum stress value of local stress concentration due to the sudden change of load and abrupt deformation of shape and structure.

Chelating fiber can multiply chelate with metal ion to form coordination compound with stable structure, so it has large adsorption capacity for metal ions.
In addition, chelating fiber with the different structure has excellent adsorption selectivity for metal ions[3].

As the main-chain structure of the copolyesters became more random and harder to crystallize, Tm of the copolyesters decreased.
This was thought to be due to the introduction of noncrystallizable components MD, resulting in the lowered crystallization rate and the random structure of the copolymers.

Community structure is an important property of complex networks.
Study on the community structure of complex networks is of great significance to control the spread of the disease and the network transmission of the virus.
Genetic algorithms find application in bioinformatics, computational science, engineering, economics, chemistry, manufacturing, mathematics, physics and other fields. 1.1 The Basic Framework With reference to the Introduction to Genetic Algorithms, written by Mitchell, a professor of the University of Cambridge, UK, the fundamental framework of genetic algorithm can be defined as follows: 1) Initialization.
