Collecting relevant materials and analyzing data, we could summarize that impoverished university students’ consciousness in the protection of rights and interests was very optimistic, security interests’ rate in 2009 rose to74% from 49.7% in 2008, as shown in Figure 2.
This paper uses the DPS software for grey system forecasting model GM (1, 1) to analyze[10]. ①Do cumulative generation of data sequence (1), get formula (2)
Chinese impoverished university students’ rights protection standards from 2007 to 2010 Use the data in Table 1to establish the gray prediction model, doing a long-term prediction on our university students' rights protection standards and the dynamic development trends of poor university students’ number.
Through calculation and analysis, we obtained the data in following Table 2 and Table 3.

However, it has as limitations the phenomenon of formation of a polarization layer by concentration, which causes, in the long term, the reduction of permeate flux.
This behavior happens because that increasing of the oil particle size provides a reduction in the specific resistance of the polarization layer, rp, making it more permeable, and thus increasing the permeate flux.
It is observed that an increase in temperature causes a reduction in the system total pressure; this behavior is associated with the reduction of the fluid density and viscosity upon heating, thereby causing a reduction of the feed velocity, and consequently, reducing the pressure exerted by the fluid along the flow.
This promotes a velocity reduction with temperature, and lower velocity gradients in the region near the membrane surface, due to the formation of the polarization layer, which hinders flow.

The XRD data illustrate the transition in structure type at approximately 30-40 mol. % GeO2.
We provide evidence for an unexpected reduction of the germanium energetic state (to Ge(II), according to XPS data) under thermal treatment in air, with a decrease in the Zr(IV) content [3].
The XPS data on the valence band structure of ZrO2-GeO2 samples calcined at 900 oC in air (Fig. 6. d) somewhat supported the idea of "double bond" formation.
Fig. 9 XPS data of Ce 3d and Al 2p core levels for the Ce-Zr-Al-O glassy sample calcined at 900 o C.
This result is in good agreement with EPR data and, in particular, with an increasing Ce3+ concentration (almost ten times) with increasing annealing temperature.

Differential scanning calorimetry (DSC) measurement indicated that the presence of CMCB the reduction of glass transition, and melting temperatures.
In work accomplished by Iwatake and co-workers, they found the increment in Young’s modulus and tensile strength of the 10 wt% microfibrils filled PLA composite by 40% and 25%, respectively without the reduction of glass transition temperature (Tg) [6].
In the part of second heating scan, the results of PLA/CMCB composites exhibited the glass transition temperature (Tg), cold crystallization temperature (Tcc) and two melting temperatures (Tm1 and Tm2), revealing that the Tg are approximately 51 – 57 ºC (lower than those of first heating scan data) and Tcc are around 106 – 120.9 ºC.

Besides that, the mechanical properties also showed a reasonable reduction in flexural strength and modulus of the epoxy porous obtained from toluene extraction compared to distilled water extraction.
Fig. 5 : Dielectric constant value of porous epoxy using water plus ultrasonic Fig. 6 : Dielectric constant value of porous epoxy using toluene plus ultrasonic Conclusions Porous epoxy thermosets were successfully prepared from epoxy/latex/ hardener system using toluene and water as extraction medium using ultrasonic method .From the data, effect of toluene on epoxy system showed the better porosity compared to water and it can be concluded that toluene is the better extraction medium on forming the porous epoxy.

The lower pressure of hydration reaction system ,the larger induction time of CO2 hydrate reduction.Maximum promotion effect of SDBS was observed at 700 mg / kg which was comparable with that of CTAB at 300 mg / kg and P123 at 500 mg / kg.
Separation and sequestration of CO2 is a nearterm goal for emission reduction.Many ways can reduce CO2 emissions, such as absorption, adsorption, and membrane separation.
Experimental Apparatus The experimental apparatus, shown in Fig1, is essentially composed of a high pressure visualization reaction kettle, a standard thermostatic bath trough, a gas boosting system, an optical fiber camera system, a mass flow controller, a pressure and temperature transmitter, a data acquisition system and a vacuum pump etc.

The mechanical properties were comparable to those made using 15 % urea formaldehyde resin with reduction of formaldehyde fume was over 50 %.
However to successfully achieve that, even very little reduction of adhesive in the panels can significantly influence both physical and mechanical properties of the final product.

Introduction Polyimide coatings are successfully being used as inter-metal dielectrics [1, 2], for planarization of surface topography and overburden variation reduction [3] and for MEMS applications as structure or sacrificial material [4].
(a) SEM image of the cavity filled with polyimide and excess polyimide etched in the field area; (b) SEM image of the cavity filled with polyimide after CMP The surface profiling data of the densely placed and isolated test structures, before and after CMP are depicted in Figure 4 and 5 respectively.
The surface profiling data of the densely placed test structures, before and after CMP Fig. 5.
The surface profiling data of the isolated placed test structures, before and after CMP Conclusions The paper elaborates a wafer level polyimide filling and planarization process scheme, where the test structures are realized in 200mm wafer in different pattern densities, leading to over-burden variation of more than 6mm.

Furthermore, trap density reduction may also be achieved by oxidation in the presense of sodium, enabling the fabrication of MOSFETs with high channel mobilities [7].
The oxide thicknesses were estimated using ellipsometry and CV data.
High frequency CV data (100 kHz) for an oxide grown at 1100°C for 30 min after immersion in a 10-2 M KOH solution.
High frequency CV data (100 kHz) for a dry reference oxide grown at 1150°C for 4 hours.
The flatband shift in figure 2 is insignificant, indicating a low density of interface traps (< 1012 cm-2) in agreement with previous TDRC data [9].
