The compression ratio is a very important structural parameter of the engine, which indicates the volume of the gas at the beginning of the piston at the beginning of compression and the volume ratio of the gas volume at the end of the piston. In terms of power and economy, compression ratio should be bigger and better. The compression ratio is high, the power is good, the heat efficiency is high, the vehicle acceleration, the top speed of the car will be improved accordingly. However, the compression ratio of the gasoline engine is not too large due to the performance of the cylinder material and the vibration of gasoline combustion. In short, a high compression ratio USES a high grade fuel oil. The higher the fuel mark, the slower the oil will burn, and the lower the combustion detonation, the higher the compression ratio of the engine. On the contrary, the low-grade fuel combustion rate is faster, the combustion explosion is large, the engine compression is lower. The largest increase in the number of global blockchain participants has been so far In this way, if the interest rate of a country is higher than that of other countries, it will attract a large amount of capital inflow, and the outflow of funds from the country will decrease, leading to the buying of this currency in the international market. At the same time, the capital account balance has been improved, and the currency exchange rate has been raised. On the other hand, if a country is loose credit, interest rates fell, if interest rates lower than in other countries, can cause large capital outflows, foreign capital inflows to reduce, the capital account balance of payments deteriorates, while selling the currency in foreign exchange market, caused the exchange rate to fall. Financial staff are used to dividing the investment payback period into long-term, intermediate and short-term periods. The term usually refers to more than five years, short term generally refers to a period of less than one year, and the middle term is somewhere in between. Managers also use long, medium and short term to describe the plan. Long-term plan describes the organization in a quite long period (usually more than 5 years) and the development direction of policy, regulation on the group's various departments over a longer period of time in some activities should reach the goal and requirements, mapped the organization long-term development blueprint. Short-term plans specifically provides for all departments of an organization in the current stage, to the future the shorter period especially in the recent period of time, which should be engaged in activities, engaged in such activities should meet the requirement, and thus provides a basis for the ACTS of all members of the organization. Value is the core concept that defines the existence of human beings. It is the essence of human existence and development. All human emancipation behavior, namely the essential rule (humanity) for the creation of the self and to create and eventually reached for the essence of the law in order to maintain and development of a simple statement is all human practice is for maintaining and developing the essence of self, all value form from the category, cannot be separated from this category. Values in many areas have specific forms, such as social value, personal value, economic value, legal value, etc. The existence of these values is the essential nature of the category of human beings in different fields. At the same time, because there are some conceptualized maintenance and development of human thought there is no actual physical force, such value is defined separately as nominal value.
