eople-oriented in the name of reducing our enthusiasm. Premier Wen Jiabao's Government work report this year, identified as 7% growth, 2.1% lower than last year's 9.1%, but in 8 work remains to accelerate development in the first place ... Work standards. Second is to use the scale of development to understand. Society is evolving, human needs are also changing. Practice of humanism is a long-term process and cannot be achieved overnight. o treat people if you stand still and rigid dogma, it is possible to return to this, see things but not people's old ways. Therefore, we have to follow the development of the times, and continue debugging the humanist perspective, innovative people-oriented way. Under the new historical conditions, we are requested by the times, set up a brand new concept, a high starting point, high standard of armed people, shaping, exercise, people, constantly taking the new connotation of the times. Terms of Office, is to lead the vast numbers of cadres to actively adapt to the knowledge faster and actively adapt to the increasingly high level of leadership situation, actively adapt to the demand of the masses more and more situations, eager to learn, enhance accumulation, efforts, honed the ability to overcome a good service, panic. Third is to use realistic understanding. Adhere to people-oriented must be based on reality, not divorced from reality. Desk no water cups here in Hong Kong, staff need to drink some water to the drinking fountain on a floor, the glass used is a one-time non-cone type. Drink this cup can only hold, cannot be put down. This is not only to save on glass materials, more important is to force you to get drinking water, go back to your seat business. Our emphasis on people-oriented, does not imply you can indulge the desires, the comfortable, the pursuit of enjoyment. Office of the party committees at all levels of our comrades, must continue to maintain the style of plain living and hard struggle, to stand up to the tests of temptations, exciting \on\he spirit of selfless dedication and provide services. Investee 4. clearly defined responsibilities. Putting people first is a common vision of development, everyone is a liability. People-oriented, above and below with the responsibility for coordinating system must be established and hold everyone accountable.

Leaders need to \n official term for the benefit of\ission, consciously assume responsibility for implementing people-oriented. Director of the Office of the party committees at all levels is the responsibility of the units to implement people-oriented, to manage their people, %ug in own responsibility\nce the education of leading cadres, cadres and cadres work, efforts to revitalize the Office of human resources, Office work is full of vigor and vitalityactivity, and constantly improve the physical quality of cadres and workers. Broaden the channels into his Office, increase the intensity of writing the open selection of cadres and cadres there, change text structure is not optimal conditions, and continuously improve the overall quality of cadres and workers. The second is to create a relaxed environment. With a deep affection for Office cadres, cadres and the mentality of the concern, attention to their conditions of life, do more work on straighten out emotion, to cheer on, and strive to create a lively and positive working atmosphere. Members of the leading Group Office of the party committees at all levels, more Exchange of ideas with the cadres and workers, with an equal mind, humble attitude of listening, take concrete actions to create a harmonious atmosphere. Thirdly, attention to their growth. Office is the place where talents. Leaders at all levels concerned Office cadres, as well as giving them tasks, from yadanzi, so that they get exercise and improve in practice, more political interest and to foster, increase the intensity of promoted use of Office cadres, effort into high office into a high, high, high multiple of a pool of water.

Practice of people-oriented, from man and nature, man and society, man and man to grasp the relationship between, and enhance system performance and integrity. Not long ago, Shenzhen, decided to postpone the timetable for basically realizing socialist modernization by 2005 to 2010, the main reason is a reflection of people's living standards and the indicators of progress towards sustainable development lagged. This is a rational, is also a kind of courage. As requested by the people-oriented to do Office work, be sure to keep abreast of the scientific development thought of the Party Committee, close to the local economic and social reality, keep abreast of the needs of the people, so that politics can be to the point, set to get the key. Second, to adhere to it. People can not hang on the mouth, too many, few even preaching one thing and doing the opposite. For Office work, is to better is most enriching policy recommendations, caring for the people writing the report article, many people nursing supervision, do more for most people gain Benefits of practical good. Pay particular attention to the opinions of the masses and listen to good grooming, reflects the good, guide and protect the enthusiasm of the masses, playedwell, with the effectiveness of services to defend the interests of the masses.

H0=60±0.1

增环H2 减环H1=60±0.04 H2= H0+ H1=60+50=110

ES（H2）=ES（H0）+EI（H1）=0.1-0.04=0.06

EI（H2）= EI（H0）+ ES（H1）=-0.1+0.04=-0.06 所以：H2=110±0.06
