According to operating mode requirement of valve, the material is 1 Cr18Ni9Ti, cladding materials used in the CoCrWB cobalt-based alloy powder and grain size of 200 ~ 300 mesh.
Termination condition： (7) Where is fitness function obtained from genetic algorithm， is the threshold， is small enough number。

It provides the smallest number of runs with which k factors can be studied in a complete factorial design.
Experimental Design Experiments to study the main effects (Main effect), and influences together (Interaction) that affect the hardness and grain size.

Fully eliciting combined water of soil surface is replaced and the thickness of the pervasion of soil decrease, the join forces of the soil grain are enhanced.

And a new kind of electrodeposition grinding wheel was invented by Disco Corporation [1], in which the microcapsules (5~20μm) of lubricant along with abrasive grains were deposited in electrodeposition bonding materials.
FT-IR spectra were measured on a Nicolet 6700 (Thermo, America) FT-IR spectrometer with 4cm-1 resolution and 64 scans between wave number of 4000 cm-1 and 400 cm-1.

Carbon nanotube-metal-oxide composite have been prepared by hot-pressing the corresponding composite powders, in which the carbon nanotubes, mostly single or double-walled, are very homogenously dispersed between the metal-oxide grains [10.]. 2.

Real name and ID card number must be provided to identify the visitor, telephone, email and other contact information are essential at the same time. (2)Travel planning.
Summary Transferring from traditional object-oriented concepts to service-oriented concept, encapsulation of the original systems provides a coarse-grained service which makes it independent of hardware platforms, operating systems and programming languages for the service implementation and used for other heterogeneous systems, and achieves loose coupling between the system module, which facilitates the interaction of heterogeneous data and the maintenance and expansion of systems.

. % Cu (a - the number of particles; b – area occupied by the particles of a certain size By the methods of light microscopy it is showed that the casting with 0.08 wt. % copper content had the structure of ferrite and pearlite with graphite inclusions (Fig. 2 c).
Fig. 4 – Cupric inclusions in a grey cast iron alloyed with 14.4 wt. % Cu Fig. 5 – The influence of copper on the mechanical properties of gray cast iron (1 - Brinell hardness, 2 - Perlite microhardness) Because copper is practically insoluble in iron at ambient temperature, all the remaining copper in the iron-carbon alloys was precipitated in the ferrite grains or in a ferrite of pearlite in the form of nano-inclusions or inclusions of submicron size.

Typically, the numbers for ISO settings are stated as factors of 2, such as ISO 100, ISO 200 and ISO 400 which can be up to ISO 204800 (Nikon D4 and Canon EOS-1DX, both released in 2012).
It is like getting grains when using high-speed films.

A large number of investigations on quasi-static stress-strain responses for titanium alloys have been reported [1-8].
Metallographic examination of the aging rod reveals that the microstructure of material is duplex microstructure, containing lamellae Widmanstatten structure dispersed between these primary globular α grains shown in Fig. 1.

The design of various optical interference coatings, such as antireflection, high-reflecting dielectric mirrors, band-pass and edge filters, is established on the basis of appropriate choice of refractive index, layer thickness and the number of layers.
When the concentration of Ge substituent reaches a critical level, these strong localized elastic-strain fields develop into chains of overlapping strain fields, which can pass through the entire crystalline grain.
