So diesel exhaust after-treatment technologies are the focal points for the reduction of exhausted pollutant from diesel engines.
According to the data of the Structure Commission of the International Zeolite Association, the space group of LTA zeolite is Pm-3m; Cell parameters are: a = 1.228nm, b =1.228nm, c = 1.228nm, α = β =γ = 90°; and Channel system is: <100> 8 4.1 x 4.1*** (3-dimensional).

Data on pesticide use on tropical pumpkin is not available for china, but the situation is probably similar.
While this study supports the suggestion that reduction of disease in this farming system is largely physical in nature, it also underscores the need for extended analyses of the interactions of soil ecology and plant disease.

Due to using electrical growth of family, enterprises and power equipments, the oil in lots of transformers has excess temperature because of overload, what’s more, it will lead to the oil in transformers insulation decline, oil flow electrification and transformer coil aging, even make transformers fire and explode. [1]Against the background of energy saving and emission reduction, reducing transformers’ oil temperature becomes an issue which has a great deal of social effect.
To prove the validity of this model, a set of experimental data from a experimental platform which simulates S11-4000/35 is compared to the model date.

The reduction of tube thickness is caused by fretting wear, which may threaten the safety of components [3].
After the tests, the depth profile of wear scar of the tube was recorded by using surface profile meter and these data were used for estimating approximate wear volume.

Two online algorithms are presented for variable speed limit controls at highway work zones that can take full advantage of all dynamic functions and concurrently achieve the objectives of queue reduction or throughput maximization [2].
The main functions of the fuzzification interface are to measure the values of input variables, to perform a scale mapping that transfers the range of values of input variables into corresponding universes of discourse, and to perform the fuzzification that converts input data into suitable linguistic values.

In addition to this, it is known that the reduction of area percentage of patented pearlite under tensile deformation is inversely proportional to the square root of pearlite colony [2].
Stress-strain relationship is determined by experimental data [6] which is defined by the swift equation [7] given as follows:   (2) whereanddenote as stress and plastic strain, respectively, whereas a, b and n are constants.

This can be the case not only in terms of accuracy, objectivity and time consumption of the measurements, but successively also in increase in reliability, reduction of operation costs, increase of economic effectiveness and competitiveness of the companies[3], [6] using the common interaction of suitable combination of tribodiagnostic and vibrodiagnostic methods when diagnosing the operation conditions.
Evaluation of the experiments Evaluation is done in run-in and after run-in period of experimentally found and trending values in a structure: - a time period of the measured data evaluation - measured courses of the acceleration amplitude of vibration on time - measured courses of the acceleration amplitude of vibration in dependence on the frequency - an analysis of the lubricant samples [1] (determination of the total impurities, determination of the concentration of abrasive particles and non-ferrous metals, ferrographic analysis, determination of the class of the lubricant impurities).
