Current Development Situation and Path Choice of Low-carbon Economy in Shandong Province Pan Miao Shandong Women’s University, Jinan 250300, China Email:miaopan96@163.com Keywords: low-carbon; energy-saving emission reduction; low-carbon technology Abstract: Taking the path of sustainable development in Shandong Province, it is inevitable to make “low carbon” transformation and structure adjustment of economy.
The achievements of energy-saving emission reduction are remarkable.
From statistical data of green low-carbon economic development and promotion center in Shandong, enterprise that meet the low-carbon standards was very few overall, although a lot of low-carbon environmental protection enterprises emerged, and development and application of low-carbon technologies are uneven.
Shandong finance establishes matching funds and carbon funds to support the research and development of energy conservation and emissions reduction technology in the province.
At the same time of advocating carbon dioxide emission reduction, the carbon dioxide discharged into the atmosphere will be fixed down in the form of biomass through afforestation which is the right direction to control the greenhouse gases and cope with climate change.

One such possibility is the reduction of atmospheric carbon dioxide emissions, a major greenhouse gas widely thought to be responsible for global warming.
Analysis of the results obtained is in good agreement with literature experimental data.
Experimental values were used as input data in the membrane simulation.

Data.
The authors choose 51 enterprises conducted CPA in 2010 and collect data from enterprises’ CPA reports ranging from general situation of enterprises to environmental and economic benefits.
Although quantified data for total amount of wastewater recycled and reused are not available, we still found a considerable wastewater has been reused or recycled by on-site inspection.
Reducing ISW generation is an urgent task for Qingdao in its pursuit for sustainable development. 31 enterprises that decreased ISW generation (20 enterprises did not have any reductions), saw total reductions of 167980.54 tons and an average reduction ratio of 31.20%.
Base on the data from CPA reports, the low/zero cost options implementation ratio is 90.71%, 2.65 times of that of mid/high cost options.

Foam stability was investigated through observation of the foam bubble size and the reduction of foam height inside the observation tube.
Solution with 4000 ppm of nanosilica generated the most stable foam with only 5% volume reduction [4,11].
Unfortunately the concentration was not enough for the foam to stabilize for a long period of time and also from the observation and data tabulated in Fig. 3, it shows that the foam was reduced up to 61% in 120 minutes.
CO2 foam reduction different nanosilica concentration Effect of brine concentration.
The results and data produced which were plotted in Fig. 7 demonstrate clearly that the addition of surfactant to the nanosilica solution has improved the probability of CO2 foam generation [4].

(1) Sediment reduction amount by ditch management measures.
Sediment reduction amount by ditch management measures is the sum of silt storage dam and reservoir, sediment reduction amount by reservoir is 37.52 million m3 in 1980s,if the sediment dry density as 1.4t/m3, the sediment reduction amount is 52.53 million ton, the sum of sediment reduction amount by reservoir and silt storage dam is 0.171 billion ton
(2) Sediment reduction amount by slope management measures.
The sediment reduction amount by ditch management measures is 0.171 billion ton, the sediment reduction amount by slope management measures is 92 million ton.
Based on the hydrological sediment data, under the condition that the rainfall reduced by 13% in 1980s, compared with the basis period, the sediment reduction amount had reduced to 0.65 billion ton, under the condition that the rainfall reduced by 15% in 1990s, the sediment reduction amount was 0.56 billion ton.

Noise Reduction for a Given Vehicle Based on Sound Intensity Measurement Method Zhixin Liu1, a , Yongwan Shi1, b 1China automotive technology and research center, Tianjin, China aliuzhixin@catarc.ac.cn, bshiyongwan@catarc.ac.cn Keywords: Sound Intensity, Engine, Noise Source Identification.
Introduction Recently noise reduction has become one of the primary goals of new engine development thus lots of scholars and researchers began to attach importance to noise reduction[1~5].
For the purpose of effective noise reduction, it is very important to understand the entire system of noise generation.
Analysis of experimental results The vehicle speed were chosen at idle speed,50km/h and 80km/h. the noise data of three operating conditions was measured and analyzed by the sound intensity measurement system.

Interesting data were obtained and discussed in this work.
But in the later, the reduction peak was observed around -0.8 V on Ti electrode [12].
It seems that the peaks are commonly associated with reduction process of the Cd (II) to Cd(0) [19, 20].
From the previous data of cyclic voltammetric measurements, the optimum conditions for the electrodeposition of CdS thin film at CNT are; by using a solution of a composition 0.1 M S2O32- + 0.01 M Cd2+ at pH = 2.5, t = 40 oC and the electrodeposition potential is in between the range -0.75 > E > -0.85 for a certain time.
At this period of time, it is suggested that the reduction current was proportional to the reduction of the adsorbed colloidal sulfur at the electrode surface which is more than the reduction of cadmium.

Stability margins for different motion states in rotor systems are defined based on trajectory-based stabilitypreserving dimensional-reduction (TSPDR) in a quantitative stability analysis method for rotor systems.
Experiment results in a rotor experiment rig show that regular pattern of stability margin of quasi-periodic motion calculated from measured data accords with the rule of above method.
When bifurcation diagram is calculated based on measured data by means of DASP software, point of FFT is 2048 and spectral line 2000.
Fig. 5 Stability margin of quasi-periodic motion for m=0 Fig. 6 Stablilty margin of ouasi-periodic motion foe m=0.820 Results Experiment results in a rotor experiment rig show that regular pattern of stability margin of quasiperiodic motion calculated from measured data accords with the rule of the quantitative stability analysis method.
At the same time, measured signal contains various noisy signals, and then a lot of work how to reduce noisy signals in measured data should be done in the future.

There are two ways to establish a sound data base: Manual data gathering, which is always associated with great effort or the usage of “big data”.
There are a few approaches which investigate data aggregation in particular as a type of data mining.
