Objective To look for a new complexity measure algorithm to precisely describe the dynamical properties,avoiding the losing of information contained in the original signal by coarse graining operation.

In order to explore the stability of Lempel-ziv complexity(LZC) to analyze heart rate variability(HRV),a new method and its detailed algorithm were proposed,in which LZC was calculated using equiprobable coarse graining to reconstruct the symbol series.

To improve noiseproof ability and stability of Lempel-Ziv complexity(LZC),LZC is calculated by an equiprobable coarse graining method.

Test of oilfield wastewater treatment by modified ceramics filtration ball coalescence equipment;

A new kind of ceramic filter media was utilized in the coalescence experiment of oil wastewater disposal.

Carbon-inorganic sorbent was utilized as a new type of coalescence material in comparison with traditional polypropylene, ceramsite and activated carbon.

This paper shows that for a static cohesionless granular material simply averaging in space the strains inside grains does not result in its macroscopic strain, so the fields of displacement vector and strain tensor do not have the property of coarse-graining.

The coarseness method based on genetic code was proposed to avoid excessive coarseness.

The coarseness method based on genetic code is presented, avoiding excessive coarseness.

In order to protect the Yangtze River, Jialing River and Sanxia Reservoir against pollution,compact solid-oil-water separation technology, which is based on hydrocyclone separation, filtration separation, coarsening separation as well as gravitational separation technology, is proposed.

Concerning with the pre-coarsening process often used in calculating the complexity, a fast binary quantification method is proposed which directly takes the sign bits of the complemental code of the original signal minus its mean as the bi-quantified values, thereby enabling the calculation simple and fast.

A 2-D cellular automaton(CA) model is developed to simulate nucleation,growth and coarsening of grains during the solidification of a certain material,as well as the grain coarsening after solidification.

The principles of dissolution precipitation of second phase particles and autenite grain coarsening were studied and the solubility product of NbC in austenite as function of temperature was evaluated.

A directly etching test of austenitic grains wasconducted to show the effects of different V and Nb contents on austeniticgrain coarsening, thus making provision for a rational choice of austenizingtemperature in the rolling process of the microalloyed V--Nb steel.
