The influence of blockchain in the field of Education

1. Chongqing jinwowo analyzes the impact of blockchain technology on the instry: blockchain will determine the relationship between people and all the Internet including artificial intelligence. The change of this relationship will have a subversive impact on the mainstream Internet business model and create a new era of decentralization.

2. There are many directions for ecation combined with blockchain. China's white paper on blockchain technology and application development in China and the European Commission's report blockchain in the ecation instry have preliminarily discussed the application mode of blockchain in the field of ecation
the application modes of blockchain in the field of ecation are as follows:
intelligent transaction creates an ecation Taobao platform based on Intelligent contract, constructs a community to realize the real "self-organization" operation of online learning community, non school ecational institutions join the market to participate in the formulation of ecation content, and establishes an accessible indivial learning information database to solve the problem of global academic fraud
the branches of online ecation are very extensive, and the ecological structure applied to each branch is also different. The existing online platform should grasp the opportunity of ecological optimization, not only in its own market segments, but also in the whole online ecation market to achieve continuous optimization<

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

3. The main components of explosive smoke are sorted out by Aopu mining machine for you, including CO and Co_ 2、H_ 2、NO、HCN、CH_ 4、NH_ 3、SO_ 2、NO_ 2、H_ 2s, etc. Blasting smoke is harmful to human health, especially in underground blasting
for those poisoned by harmful gas, they should be carried to the fresh airflow roadway or ground immediately, and first aid measures should be taken according to the poisoning situation
carbon monoxide poisoning. Carbon monoxide poisoning, shallow and shortness of breath, loss of consciousness when the cheek and body erythema, pink lips. Artificial respiration or oxygen delivery with hematoxylin apparatus can be used for the injured. 5% ～ 7% carbon dioxide can be infiltrated ring oxygen infusion to excite the respiratory center and promote the recovery of ventilator function

hydrogen sulfide poisoning. In addition to artificial respiration or oxygen delivery, cotton ball and handkerchief soaked with chlorine solution can be put into the mouth. Chlorine is a good detoxification of hydrogen sulfide

sulfur dioxide poisoning. As sulfur dioxide generates sulfuric acid when it meets with water, it has a strong stimulating effect on the respiratory system and may burn in severe cases. Therefore, in addition to artificial respiration or oxygen delivery with hematoxylin apparatus, the poisoned should be given milk, honey or gargle with soda solution to rece the irritation

nitrogen dioxide poisoning. The degree of lung injury depends on gas concentration and inhalation time. After exposure to more than 150 mg / m3 of nitrogen dioxide for 3-24 hours, cough, bloody sputum, shortness of breath, fever, weakness, nausea and headache may occur, and rales and wheezes may be heard in the lungs. Severe dyspnea, cyanosis, etc. They should leave the scene immediately, breathe fresh air, keep the respiratory tract unobstructed, inhale oxygen, and provide noninvasive or invasive mechanical ventilation when necessary
biogas poisoning. For biogas emergency measures, the poisoned person should be quickly removed from the scene (rescue personnel must wear aerobic protective mask) and sent to "120 & quot; Call for help; Take oxygen and send it to hyperbaric oxygen chamber if possible; Artificial respiration; Prevention and treatment of brain edema
ammonia poisoning. Remove the patient from the poisoning site immediately. Oxygen, artificial respiration and injection of respiratory stimulants. Keep respiratory tract unobstructed. Get the aspirator ready. 3% boric acid can be used as atomization inhalation for mild patients. Prevention and treatment of pulmonary edema. Maintain oxygenation. Including nasal catheter oxygen, mask oxygen, etc., use positive pressure ventilation when necessary. Oxygenation maintained the target oxygen saturation above 93%. For eye burns, rinse with water or 3% boric acid solution for at least 15 minutes. For those with skin burns, wash the skin immediately with water, 3% boric acid, 2% acetic acid, or vinegar to neutralize ammonia and eliminate burns. If there are blisters, exudates and ulcers on the skin, wet compress with 2% boric acid and apply with chemical burn oil. Large area deep burns need special treatment

carbon dioxide poisoning. Suddenly into a high concentration of carbon dioxide environment, most people can in a few seconds, e to respiratory center paralysis, suddenly fall to the ground and die. Some people can feel dizziness, palpitation, delirium, convulsion and coma. During the first aid, the carbon dioxide poisoning should leave the scene quickly and breathe fresh air or oxygen. The patient's collar should be loosened to keep the respiratory tract unobstructed; keep warm; Pay attention to observe the state of consciousness and monitor vital signs. For patients with respiratory and cardiac arrest, artificial respiration, external cardiac compression or open chest massage should be insisted. Patients with dyspnea were injected with respiratory stimulants. Hyperbaric oxygen therapy

4. In the selection of model, you can let the merchants help you introce it, or you can solve it by yourself. First, choose a crusher according to the characteristics of raw materials, cone crusher according to the hardness, and crusher model according to the required output
more information about crusher can be obtained online by consulting experts to help solve related problems.

5. Strange webpage links can be infected by viruses, so try to avoid using strange websites, and carefully open or click strange link e-mails< Most viruses can be prevented by downloading
security software from mobile phones.

6. It's equivalent to 20 M broadband, one yuan a day at most. Now it's all subsistence allowances. I have 50m broadband in my home, which costs 1.3 yuan a day at most.

7. Hisense is a professional TV procer (it has been working for more than 40 years), which is more professional than other brands. Now some brands used to make remote controls, which are not professional at all. Like some brands of TV, the quality is not very good, but they have many functions, such as home theater and game console. I feel that they are useless. TV is just watching and playing with computers, It's not strong in any way. Hisense has always focused only on the quality of TV and spent most of its money on how to improve the picture quality. For example, the international standard of LED is set by Hisense. Hisense has two skills in TV technology, so he has the confidence to say that he is better than others and the price is higher. I personally think that as long as the price difference is not too much, it's better to have a better TV
