What is the difference between M1A1 and M1A2?

The software and hardware are all graded.

M1, M2 and M3 represent Class I industrial land, Class II industrial land and Class III industrial land respectively.

Differences: 1. The degree of environmental pollution is different.

The first type of industrial land refers to the industrial land that is basically free of interference and pollution to the environment such as residential and public facilities.

Class II industrial land refers to industrial land that interferes with and pollutes the environment such as residential and public facilities.

The three types of industrial land refer to the industrial land that has serious interference and pollution to the environment such as residential and public facilities.

2. The land use industry is different.

The first type of industrial land includes the electronics industry, the sewing industry, the manufacturing of handicrafts, etc.

The second category of industrial land includes real estate, sports, entertainment, etc.

The second-class industrial land includes mining industry, metallurgical industry, large and medium-sized machinery manufacturing industry, chemical industry, paper industry, tanning industry, building materials industry, etc.

Type of industrial land.

The types of industrial land refer to the three types of industrial land that are divided into three types according to the "Standards for the Classification of Urban Land and Planning and Construction Land". Including industrial land that is basically pollution-free, has a certain disturbance and pollution to the environment, and has serious interference and pollution to the environment.

In urban planning, industrial land can be divided into three categories:

1. Class I industrial land: industrial land that has basically no interference and pollution to the environment such as residential and public facilities, such as electronic industry, sewing industry, handicraft manufacturing industry, etc. It is indicated by the letter M1 in the planning drawings.

2. Class II industrial land: industrial land that interferes with and pollutes the environment such as residential and public facilities, such as food industry, pharmaceutical manufacturing industry, textile industry, etc. It is indicated in the planning drawings by the letters m2.

3. Three types of industrial land: industrial land that has serious interference and pollution to the environment such as residential and public facilities, such as mining industry, metallurgical industry, large and medium-sized machinery manufacturing industry, chemical industry, paper industry, tanning industry, building materials industry, etc. It is indicated in the planning drawings by the letter M3.

The difference between A13 and M1 is the performance.

M1 core is a radio frequency chip, which refers to an electronic component that converts radio signal communication into a certain radio signal waveform and sends it out through antenna resonance.

It includes power amplifiers, low-noise amplifiers, and antenna switches. The M1 has more powerful single-core, multi-core, and GPU performance.

The A13 bionic chip is a power amplifier chip, and its technical parameters are, input sensitivity 20, harmonics.

Distortion 30, signal-to-noise ratio.

32db, frequency response 21, damping coefficient 32, slew rate 22. The function of the power amplifier chip is to amplify the weak signal from the audio source or preamplifier of the year and promote the sound of the speaker.

In terms of GPU, M1 is also the same as A14, but the scale is much larger than A14, A14 is a quad-core GPU, and M1's GPU has eight cores. The A13 GPU is a quad-core design that delivers 20% faster speeds and 40% lower power consumption. At the same time, the A13 also has an 8-core neural computing engine, which improves performance by 20% and reduces power consumption by 15%.

Key features: A13 BIONIC

Performance has been greatly improved, but battery life has not decreased, **iPhone 11 battery life is better than iPhone XR

One hour longer, iPhone 11 Pro

has an extra 4 hours of battery life and 5 hours more battery life for the Pro Max.

M1 and M2 are the categories of monetary **. People generally divide the amount of money into different levels according to the size of liquidity to measure, analyze and regulate. In practice, countries have a good understanding of m.

The definitions of m1 and m2 are different, but they are all divided according to the size of the liquidity. is the most liquid, followed by M1, and M2 is the worst.

At this stage, China is also dividing the amount of money into three levels, the meanings of which are:

m。: cash in circulation, i.e. cash circulating outside the banking system;

m1: the amount of money in the narrow sense, i.e. m. demand deposits of enterprises and institutions;

M2: Broad Money** Amount, i.e. M1 Time Deposits of Enterprises and Institutions Residents' Savings Deposits.

Of these three levels, m. It is closely related to changes in consumption and is the most active currency;

M1 reflects the changes in the tightness of household and corporate funds, and is a leading indicator of the fluctuation of the economic cycle, and the liquidity is second only to M.

M2 liquidity is weak, but it reflects the changes in aggregate social demand and future inflationary pressures.
