He said he believes "this is really a long-term trend in pushing for continued use of memory and storage."

Gasoline is produced and sold according to the brand name, and the specifications of the brand are regulated by national gasoline product standards and are related to different standards. At present, there are 3 gasoline license plates in China (IV), which are 90, 93 and 97 respectively. The state (V) is 89, 92 and 95 respectively (98 in the appendix). The number of gasoline is divided by octane number. For example, gasoline on 97 refers to a gasoline fuel equivalent to 97 percent of isooctane and 3 percent of n-heptane resistance. The larger the label, the better the anti-knock performance. Depending on the engine compression ratio, you should choose the different brand of gasoline, which will be indicated on the manual of each vehicle. A mid-range sedan with a compression ratio of 8.5-9.5 should generally use the 90 (country IV) gasoline, and the car with a compression ratio of 9.5 should use the gasoline of 93 (country IV).
