Most sustainability measurements are driven from the matrices or a set of indicators such as benchmarks (e.g. base-line global data), indexes (e.g. air quality and environmental vulnerability index), biogeochemical cycle metrics (e.g. carbon and water cycle), accounting and auditing (e.g. input-output analysis, triple bottom line), resources metrics (e.g. energy accounting, price system) [8, 9, 10].

The delay time of the circuit is set to , is much smaller than the time that ultrasonic transports in the fluid, therefore:

In general industrial measurement, ultrasonic velocity in the liquid (about 1450m / s in the water) much larger than the flow of liquid, that is , the time difference can be simplified as:
(2.4)
Therefore, the basic equations of the time difference ultrasonic flow meter instantaneous velocity can be written as:
(2.5)
Then, the instantaneous flow is:

As for PET bottle which is the most popular in wine packaging development, it has excellent barriers, such as CO2, O2 and water, and aromatic flavor performance, high physical specialty, good machining ability, formability, stability, ability of resisting surface damage, anti-cracking advantages, lightweight and so on, it can also be recycled, conveniently transported .it has come into the market in many countries with great potential
The main reason is that professional groups engaged in the design for box type are very few. so the plane design is often good but box type is unsatisfied, or box type design is good although, but the two can't be combined perfectly for printing technology and other reasons that results in failing in volume production.

Its introduction in orthodontics occurred in the 1970s, which brought irreversible changes in the corrective treatment techniques for both the patient and the professional, allowing large activations with the use of light and constant forces[13].
Subsequent to the forging a solubilization heat treatment was performed at 850 °C for half an hour with rapid cooling in water.
