At least six specimens were tested for each data point.
The replacement of non-siliceous ions by hydrogen ions in the depleted sheath will cause a reduction of molar volume, leading to shrinkage of the sheath.

Simultaneously, the technique can record and analyze collecting data automatically, and
then use for real-time monitoring, measurement and control.
Fv/Fm demonstrates maximum efficiency at which light absorbed by light-harvesting antennae of PSII is converted to chemical energy (QA reduction). qP monitors the apparent rate constant for photochemical electron transfer from PSII and its antennae. qN or NPQ monitors the apparent rate constant for non-radiative decay (heat loss) from PSII and its antennae.

Here's an instance of a landslide in the Three Gorges Reservoir Area.
4.1 The establishment of the three-dimensional model
Based on the monitoring data of a landslide of the Three Gorges Reservoir project, a computational model can be established: the length along the flow direction is 960m and perpendicular to the direction of flow is 1240m,the model ground elevation is 0m and the model contains landslide body, sliding zone and bedrock, there are 12,054 hexahedral unit (unit type C3D8R)and 14272 nodes in the entire computational model, on the three reference points A, B, C, respectively, as a node 635,415,127 is selected on 1-1 cross-section for research.
Among them, the change of the horizontal displacement of the reference point A is different from reference point B and C, it is a process which the value at first decreases and then increases due to rainfall infiltration and suction and the effective stress reduction, all of it causes the unloading rebound phenomenon; since the end of the rainfall, the increasing of moisture content and unit weight of the soil led to the increasing of the settlement and stress.

In the fault diagnosis of smart grid, it usually involves a great deal of uncertainty knowledge and data caused by such factors as the protection or breaker maloperation, refusing action, protect the action time deviation, these all need uncertainty reasoning.

But these are not the urbanization data can be displayed.No country is to set targets to achieve urbanization,and no country can be like this "super speed" to promote the urbanization.As we konw,in addition to the economic benefits of this pricing growth, social, cultural, environmental, and public mental aspects can not be denominated .For example, the degree of residents 'comfort, lifestyle adaptability,dependence of the living environment.There is no way to calculate these factors .However, these have profoundly affected the living standards of the residents.Therefore,people's life is more important than the index of urbanization.
In order to save this situation, the state had to take a mandatory population migration.Pepple have to move out of the city Passively.Under the manipulation of the rapid urbanization of this country ,the farming population is greatly reduced and farmers' enthusiasm in production reduced.The result is a substantial reduction in grain yield.The country had emergency food imported from abroad due to the severe shortage of food in 1961.
