More and more users are willing to share opinions on microblogs, blogs, forums and other platforms to exchange ideas and emotions which include a large number of users’ comment on events, products, people and other objects.
The advantage of using sentiment dictionary to analyze the text sentiment is the precise fine-grained classification on word level and sentence level.
(2) If a negative word wb appears around wi to qualify the sentimental word, judge whether to invert the polarity of wi according to number of negative words.

(2) Where I(∙) is indicative function, and ε is tolerance. m and n respectively indicate the number of bands of sample A and B. z- and z+ indicate the minimum and maximum of band.
Although carrying on statistics and analysis the total records is possible, the results are at a much coarse-grained level for user multiple interests.
Fi indicate the request rate of user for a particular type image, which it equals to divide the number of one cluster by the total of user’s historical record.

Introduction With the rapid development of the electronics industry, the number of passive components in electronic products gradually increased and the miniaturization of electronic devices is still one of the development trends.
And the large number of defects inside the material and at the interface cause the change of charge distribution so as to promote the charge polarization.

The band at the range (1067.79-1420)cm-1 is for stretching bond of C-N, in addition to appearance a number of bands such as C=C at(1609.79)cm-1 ,Benzene ring band at (1507.8)cm-1 .
Wave number (cm-1) Transmission %100 ℅ T) Figure (10): FT-IR spectra of CuPc powder.
The value related to optical energy gap is slightly decreasing as thickness is increased, such behavior has been because of the growth related to grain size as well as the increase in defect states near the bands.

The color of the grains ranges from light gray to dark gray depending on the content of impurity components (e.g., iron compounds, unburned particles) [7].
As the analysis shows in comparison with quartz sand, fly-ash as the siliceous component of aerated concrete has a number of advantages.
As known that the addition of gypsum intensify the interaction of Ca(OH)2 and silica, resulting in an increasing number of low-basic calcium hydrosilicates and increases the strength of cement stone [8].

However, with further increasing thickness of ITO layer, the number of layers will increase, because each layer has its own coefficient of thermal expansion, the bonding strength will decrease too [5].
Therefore the suitable annealing temperature and the number of layers for strong adhesion and stable performance of ITO films is 500℃ and four.
The size of In2O3 is small (16.5 nm), so the value of the resistivity is mainly related to the grain boundary scattering [6].

The number of unstable slope increases year by year and harm increases too.
After carried out, the core should manner number timely and identification and sealing wax, work, and then carried out in accordance with the relevant procedures for sample processing and experimental research.
Influence mainly depends on rock grain size, pore size, the condition of transition, clean degree and contain of hydrophilic minerals and other factors.

Also, due to the existence of symmetry to process route C, it is possible to decrease half the number of elements to make the calculus.
This will mean that the grain size after appropriate thermal treatment is smaller than the equivalent obtained with a drawing process, so the mechanical properties (toughness, yield stress, ultimate strength stress) will be improved.
Therefore, it is possible to obtain higher values of deformation with a lower area reduction, and hence the number of passes can be reduced with a consequent decrease in the manufacturing costs.

However, the number of wear particles released during the articulation of head and cup is higher, because the particle size is lower ranging on a nm scale [5,6].
Comparing the grain size and shape of the nano-cystalline zone with the analysis of isolated wear particles from retrieved and simulator tested hip joints by Catelas et al., it becomes obvious that they have the same nature [6, 22].
Catelas: Size, shape, and composition of wear particles from metal-metal hip simulator testing: Effects of alloy and number of loading cycles.

Select the numbers of those uniform-grained specimens without serious defects as test materials.
However, a too high salt concentration will lead to aggregation or precipitation of dye in the solution and in the process of fixation, a large number of Cl ions will hinder the affinity substitution reaction between dye molecules and fiber, thereby decreasing dyeing effects.
