In order to weaken the randomness of the original data, and strengthen the regularity of the original data, we take a weight average of the original data.
In order to predict the load data of the next period or the next few days more accurately, this paper adopts the metabolism method, by which we remove the old data and fill in the new data.
If the data of 1-4 days is known and now has measured the data on the fifth day, the window shifts to the right of a cell when forecasting the data of the sixth day, letting go of 1 and snatching 5.
In this way, we not only ensure the equal dimension, but also obtain the latest forecast data as samples of the original data.
The original data, and forecast results shown in Table 2, prediction test as shown in Table 3.

Optical detection methods, such as cadmium reduction and phenol disulfonic acid spectriphotometric, are commonly applied for nitrate-nitrogen detection by using the wavebands of 400~425nm or 510~550nm with an accuracy of 0.1~2mg/L [4].
Besides, problems like size reduction and system integration still remain unsolved, because these nitrate-selective electrodes commonly require inner filling solution.
A micro controller was selected for data processing.
Average potential data of 10 times ISEs readings could be displayed on the micro controller and sent to the lap-top computer. 6 Miniature pumps and 5 miniature valves were used to achieve the solution delivery.

Thus the reduction or elimination of the Mg17Al12 phase is essential to improve the elevated temperature properties.
However, studied τ-type alloys usually contain large amount of elements, especially comparatively heavier element of Zn, which risks the weight reduction advantage and decreases the ductility due to the larger amount of interdendritic phases.

At the onset of zinc deposition, a sharp reduction in current is observed, which may be caused by the formation of crystal cores.
In addition, compared with the organic additive TBAB, a significant reduction in current at the starting stage is not observed in the electrolyte with the lead inorganic additive.
Data taken from the current–time profiles are summarized in Table 1.
The data from these tests indicate that both additives exhibit superior performance to the blank solution.

Current study was focused on cost reduction from analysis of single-function micro perspective, which leaded to hard macro-system planning with insufficient analysis of the entire structure of the social system.
Don't attend to trifles to neglect the essentials, and don't pursue the cost reduction blindly.
