2. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis

in other words, blockchain solves the problem of trust and security

the st entering the dial of Swarovski watch is usually e to the graal infiltration ring long-time wearing. If you only enter the fine st, you don't need to clean it without affecting the appearance and use. However, if the st with a certain length, such as hair or acrylic fiber, enters the watch dial, attention should be paid to it, because such st is extremely likely to cause the watch to stop working

when we find that the Swarovski watch is sty, we should not easily open the back cover of the Swarovski watch for cleaning. We should promptly send it to the Swarovski customer service center [30th floor, Tianjin International Financial Center, 136 Chifeng Road, Heping District] for cleaning, and regularly do the waterproof test and travel time accuracy test to ensure its normal operation

at the same time, we should also pay attention to the Swarovski watch not to come into contact with chemicals in our daily life. Waterproof watch can prevent cold water but not hot water, so don't take a bath with it. Avoid water vapor to ensure its waterproof effect.

5. 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
