SNS corpus is a sample collection of the real language. 1) Language materials in the corpus should be taken from the real texts actually used.
Corpus collection, choose the appropriate language materials to prepare corpus annotation in advance.
In general, the language materials usually choose strong interest，strong literary flavor，colorful emotional expression language.
Corpus annotation system refers to the degree of processing on the language materials.

That is to say, the relaxation of residual stress is concerned with the applied load and the materials propriety.
In shot peening processing, the stress induced phase transformation usually takes place for certain materials, and residual stresses in different phases must be evaluated with an X-ray diffraction technique.

It can also be used as electrode materials[5], and is the most important precursor of hematite (α-Fe2O3)[6].
Herein, we develop a facile route to prepare the composite α-FeOOH superstructures using FeSO4 and NH3 as main materials.

China Keywords: Glass ceramic, mica, machinability, strength, melting temperature, dental materials, mechanical properties Abstract Traditional mica glass ceramics have excellent machinability, but they show relatively poor mechanical strength that restricts their applications in many load-bearing situations.
High mechanical strength were also achieved in these studies, but it normally accompanied by high melting temperatures, 1500°-1600°C [2, 4-6], which lead to the high processing cost and great difficulty in material processing.
This glass ceramic had a relatively low melting temperature, good machinability, and superior strength. 2 Title of Publication (to be inserted by the publisher) Materials and Methods In order to lower the melting temperature of conventional SiO2-MgO-Al2O3-K2O-F glass system, B2O3, Li2O, and ZnO were added to the system.

The microstructure of the matrix material is shown in Fig. 1a, in which α phase (white) is a branched microstructure.
