The fluid structure interaction vibration and dynamic strength failure of the pipe are the main outstanding problems, which are induced by the pressure pulsation [3].In addition, increasing the working pressure of the hydraulic power pipe is the equipment’s requirement of the future war [4].
Before increasing the working pressure of the existing hydraulic power system, the pipe structure and component parameters must be adjusted to decrease the pressure pulsation amplitude.
The working pressure of the existing hydraulic power system could be not improved until the pipe structure and component parameters are adjusted to decrease the pressure pulsation amplitude.

The morphology surface and chemical structure of electrospun fibers were studied by SEM and FTIR, respectively.
In addition, the chemical structure of electrospun fibers was analyzed by using Fourier Transform Infrared Spectroscopy (FTIR).
First, we investigated the chemical structure of electrospun fibers using FTIR, as a result showed in Figure 3.

Synthesis and Properties of a New Asymmetry Diarylethene 1-{2-methyl-[5-(4-methylene-hydroxyl)phenyl]-3-thienyl}-2- [2-methyl-5-(10-phenanthrenyl)-3-thienyl]perfluorocyclopentene Hongjing Jia and Congbin Fan* Jiangxi Key Laboratory of Organic Chemistry, Jiangxi Science and Technology Normal University, Nanchang 330013, P.
Introduction In the filed of organic chemistry, photochromic compounds, which can undergo a photo-induced reversible transformation between open-ring and closed-ring states upon irradiation with light of appropriate wavelength [1], play an important role.
Phenanthrene has attracted people’s attention, which has a rigid planar biphenyl structure, owing to these compounds bearing wide energy gap and high luminous efficiency.
To the best of our knowledge, longer conjugate structure can reduce the diarylethene energy difference between open- and closed-ring isomers [7,8].
The structure of compound 1o was characterized by 1H NMR spectroscopy.

The coating exhibits an almost amorphous structure in the absence of saccharin whereas at the least level of saccharin as in Fig. 3(a) well defined boundaries and somewhat crystalline structures are observed.
The globular formations with circular or almost quasi circular formations in Figs. 4(b, c, d) also suggests that real grain boundaries probably exists between the individual grains pointing towards the prevalence of somewhat crystalline structure.

There are two kinds of SOFC structure have been already demonstrated the technical feasibility of SOFC, one is called tubular SOFC construction, another is the planar type.
A new unique SOFCs structure named honeycomb fuel cells is developing [2-4].
Considering that the honeycomb-type's SOFC is a kind of self-supported cell structure, the thick electrolyte wall would dominate the whole cell's power output.

Single Walled Carbon Nanotubes (SWCNTs) Assembled Site-Selectively on Flexible Substrate Xing Li1, a, Xiang Junhui1, b, Zhang Fushi2, Liang Xiaohong1, Song Bo 1 and Yang Jingkui1 1 College of Chemistry and Chemical Engineering, Graduate University of Chinese Academy of Science, Bei Jing 100049, China 2 Department of Chemistry, Tsinghua University, Bei Jing 100084, China a xingli05@mails.gucas.ac.cn, b xiangjh@gucas.ac.cn Keywords: Single walled carbon nanotubes; Site-selectively assemble Abstract.
Roman sepec- troscopy was employed to confirm that SWCNTs structure is keeping or not after treatment by mixture acid.
The results show that the graphite structure of treated SWCNTs is still keeping although SWCNTs are partly oxidiated.
By this way, it is conceivable to fabricate well-defined structure on the expected site of other substrate, and further accomplish the site-selective assembling of one-dimension nanomaterials.

Specifically, the osteogenic capacity of CaP ceramics was shown to be dependent on chemical properties - such as the coating composition, crystal and molecular structure and coating crystallinity - and physical properties, such as surface roughness and porosity [3].
However, using conventional deposition methods like plasma-spraying or sputter-deposition, coating properties (in terms of coating chemistry and morphology) can be varied only to a limited extent.
The amount of carbonate incorporation (ranging from 0 to 15 wt% as quantified using an infrared method [9]) determined the crystal and molecular structure of the deposited coatings.
Increasing the deposition temperature to 350 °C (Fig.2b) yielded a reticular coating morphology characterized by an interconnected pore network resembling a sponge structure.

However, in the past research, all the studies focused on how to eliminate lignin, the structures of lignin after degradation were ignored.
While H3PMo12O40 has the keggin-type structure which is made of a PO4 tetrahedron as the center and cage of Mo12O36.
This structure of H3PMo12O40 can accommodate more electrons.

These gold nanoplates gave a dominant (111) diffraction peak of metallic Au which is very strong compared to the (200) peak (Fig. 2) and reveals that gold nanoparticles were face-centered cubic structure.
When a sample with pH=2 was heated at 80 oC for 4 h, the gold network structures were prepared (Fig.3a).
This method may be used to control other noble metal nano- or micro-structures.
