Data in Table 2 show that, Compared with other countries, China put more critical public services delegated to lower levels of government.
The importance of China's emissions reduction policy analysis: The first, emission reduction policies can improve the efficiency of the transport industry and the price and other industries to reduce China's demand for imported fossil fuels.

In Fig.3, when the engine speed becomes larger, the exhaust noise will be larger; from the perspective of noise elimination, the installation of the exhaust muffler is an effective measure to reduce exhaust noise, but relative to the low speed, the noise reduction is still relatively small; In exhaust spectrum of original muffler, the noise elimination is relatively poor in 700Hz, 1500-3000Hz.
In contrast with exhaust noise spectrum data in Fig.3, the result of equivalent gradient method with consideration of the temperature and velocity field is closer to the test results.
It can be seen from Fig.6(b), the exhaust noise of improved muffler than the original muffler has average noise reduction 5.1dB (A), thus it does not affect the engine output power, as shown in Fig.6(a).

However, the overall palm thickness variance in Figure 2 demonstrated a slight reduction of film thickness in treated former.
This allows the coagulant coating to be distributed more evenly compared to the untreated former, resulting reduction in visual defects and heavier gloves, without remarkable compromises in glove thickness and mechanical properties.

According to the data in table 6, among three methods, sulfate solution freezing-thawing method is the most accurate method, on the contrary, apparent density method has worst accuracy, and quench hot method is the moderate one.
When at a high temperature of 400ºC, C-S-H gel starts to dehydrate and decompose, interlayer water and chemical bonding water start to drain, and Ca(OH)2 starts to decompose, causing the destruction of initial lamellar structure of integrated crystallization, strength of recycled aggregate showing significant reduction, cracks appearing.
Because of residual mortar, strength and elasticity modulus of recycled aggregate are lower than that of natural aggregate, resulting in the reduction of mechanical properties of structural elements with recycled concrete, and then the reliability reduces.

The application of three coatings on Ti-based alloy substrate leads to a reduction of mass gain at 700°C (Fig. 3a).
%-Ag added ternary coating have a similar initial stage of mass gain at first 20h, whereas the latter two samples show a dramatic reduction of mass gain at subsequent oxidation, different from the continuous up growth of uncoated substrate.
The Kp value of ternary coating is supposed to be smaller than that in this study, compared with the data in other literature [10].

The subsequent decisions are to manage the
future inspection, repair and maintenance planning in the risk reduction control.
Semi-Quantitative RBI The semi-quantitative RBI procedure is almost identical to quantitative one; contrary to the latter, however, the former doesn't demand accurate data on the terms of the inventory group and makes a calculation in the same way with quantitative RBI considering flammable and toxic consequence areas alone.
This result is different from that of the general 80/20 version [3], for the following reason: The equipment ranked High-Risk means that the risk of the equipment is so high that it requires intensive management, which could provide data required by assessment with available detailed information on design data, inspection history, and measure record.
However, these ranked Medium High seemingly generated conservative assessment and results due to insufficient input data and absence of information on risk mitigation though they weren't indeed very dangerous, exclusive of several items.
In other words, there is high likelihood that those records will be omitted on any possible repair or replacement and it is evident that RBI using these data will produce conservative results, which is a significant example of how important it is to manage history data.

Hardness measurement demonstrates that the addition of Y increases the hardness gradually but a reduction in the hardness of heat treated specimen’s occurs with the addition of Y (³ 0.5%Y).Wear tests were performed using a pin on disk apparatus.
Quantitative data on the microstructures were determined using an optical microscope equipped with an image analysis system )MIP).
In general, the reduction in wear rate is influenced by the efficiency of refiner and solution results.
