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. Profit is not only the same in quality, but also the essence of profit. Profit is the form of corporate profit, and is also equal in quantity. The difference in profit is that for variable capital, profit is for all costs. Once earnings into profits, therefore, the origin of profits and material production is made it is a reflection of the "(" the complete works of Marx and Engels in volume 25, page 56), and thus has the various forms of money. In capitalist society, the essence of profit is: it is the product of capital, it has nothing to do with labor. Mr Trump's deceptive tweets about us companies, pushing for offshore production or tax reversals, are only cheap talks, and business leaders know. The manufacturers fooled Mr Trump into thinking they would continue to quietly move their operations to Mexico, China and elsewhere in the us. And the upcoming international terms of tax legislation will make American multinationals have greater incentive to investment, employment and production abroad, at the same time the use of transfer pricing and other solutions in the lower stripping profits tax area. Mehrotra said the additional rate for PC flash drives in 2017 is about 35 percent, and will increase to 75 percent by 2020. And "a lot of hard drives still need to be replaced by SSDS... Future self-driving vehicles are expected to be equipped with about 40GB of DRAM... This will also drive the use of NAND flash memory." Recently, Apple Inc. announced its astonishing sales record within the Greater China region at US$3.8 billion in latest three-month period, probably leading Apple to surpass the region's pc giant Lenovo Group the first time in a minimum of several years. Let's follow this article and see how amazing Apple's revenue is through the third quarter of 2011.
