Furthermore, the pump could not work in its operating pressure resulted in significant losses in journal bearing damage and production interruption.
Under normal conditions, it would not cause corrosion to low alloy steel material[1].
The anatomical analysis shows that the grooves and pits over the sealing surface have penetrated deeply into the material.
Crater formation moves surface material to the edges of the craters, and these extrusions eventually break off, causing loss of material from the surface[4].

The Experiment of the Performance of Interior Moisture Buffering Materials The experiments of the performance of moisture buffering materials follow the instruction of JIS A1470-1:2008 standard at daily cycle (12-hour adsorption, 12-hour desorption) mainly for building materials such as interior materials in response to humidity variation (Figure 1).
In this study, the researchers picked 7 different materials, both granular and plate, which are all local building and interior materials in Taiwan, except moisture buffering tiles (Table 1, 2, and Figure 2).
Testing Interior Moisture Buffering Materials (Upper row is the plate materials; lower row is the granular materials) The study of typical residential buildings in Taiwan Table 2.
For now, the study completed 6 local materials and also 1 imported material (moisture buffering tile) as a comparison.

Study on The Controlling System of Particle Materials Separating Device Li Li1,a, Yongqing Gu1,b,Wei Zhang1,c,Meiying Qiao1,d,Hong Shen1,e 1Henan Institute of Science & Technology, Xinxiang 453003, China alilinhist1999@163.com,bhngyq@163.com,czhangwei@hist.edu.cn,dqmy@hist.edu.cn, eshyl99@hist.edu.cn Key Words: vibrating sieve, ultrasonic wave, controlling system Abstract: The present thesis proposes the controlling program to separate the particle materials by making use of low-frequency ultrasonic wave, and elaborates the design of system circuit controlling the ultrasonic vibrating sieve.
Introduction Separation of particle materials is an indispensable program and process of industrial manufacture.
By inputting the ultrasonic transducer, it introduces a low amplitude and high frequent ultrasonic vibrating wave onto the screen on the basis of traditional vibrating sieve for improving the screening performance of superfine Materials.
Interconnecting the 3525 chip with peripheral circuit to generate the main frequency of ultrasonic wave, enlarging the output current by power amplifying circuit and producing the additional wave by SCM(Single Chip Micyoco)for fine adjustment, the system is able to separate the materials by vibrating the screen rack which is moved by transducer.

Introduction Concrete is a kind of manufactured materials which is the most widely used [1].
At present, nano materials that researchers usually used to modify cementitious materials were nano-SiO2, nano-clay, nano-Al2O3, nano-Fe2O3 and nano-CaCO3.
When the content of NA was 2%, the machanical properties of modified cementitious materials were improved most.
So to different nanoparticle, it had the optimal content to modify the properties of cementitious materials.

Materials Decisions about material procurement may also be required during the initial planning and scheduling stages.
The availability of materials may greatly influence the schedule in projects with a fast track or very tight time schedule: sufficient time for obtaining the necessary materials must be allowed.
(material ordered very late – buffer at supplier, material ordered very early – buffer at site) 0.643 6 The size of construction site and material storage location - labors require extra time to move materials. 0.629 Table 3 shows materials issues in construction project as ranked per relative importance index analysis.
