ActiveCN101928179AReduce the frequency of fertilizationImprove repair efficiencyContaminated soil reclamationFertilizer mixturesBiologyNutrients substances
The invention discloses a slow release fertilizer having a soil remediation function. The slow release fertilizer is prepared by mixing fully-biodegradable polyhydroxyalkanoates and organic and inorganic nutrient substances. The fully-biodegradable polyhydroxyalkanoates is slowly degraded under the actions of soil microorganisms to provide nutrient substances needed by the growth of the soil microorganisms so as to promote the ionization effects of the soil microorganisms on heavy metals and release the organic and inorganic nutrient substances by slow degradation so as to promote durable and rapid growth of plants and improve soil remediation efficiency. The invention also discloses a soil contamination remediation method for using the slow release fertilizer. High-efficiency, environmentally-friendly and durable remediation of heavy metal-contaminated soil is realized by planting plants having hyper-accumulation capability to absorb and extract the heavy metals in the soil to which the slow release fertilizer is applied.

The invention discloses a method for preparing a thermal barrier coating. According to the method disclosed by the invention, a deposition matrix is bombarded by ion beams while a deposition coating is evaporated by electron beams, the steam energy of the electron beams is about 0.1-1 electron volts, and the energy is not enough to well migrate atoms in the process of depositing the coating; and the energy of the ion beams can reach thousands of electron volts, and the energy is enough to interfere growth of columnar crystals to increase crystal boundaries and crystal sub-boundaries and enlarge or increase microscopic holes so as to reduce phonon and photon scattering mean free path and reduce the thermal conductivity of the thermal barrier coating. The energy of vaporous clouds can be increased through activation ionization effects of ions; and compared with the conventional EB-PVD (Electron Beam Physical Vapour Deposition), the method can ensure that same performances can be achieved at low deposition temperature; furthermore, forms, structures and stresses of the columnar crystals can be also adjusted and controlled through ion assisted deposition, and thus, the service life ofthe thermal barrier coating can be prolonged.

A water heater is controlled by an electronic system that initiates the operation of the heater when a flow detector sends a demand signal for hot water flow to the electronic card, which ignites a burner as function of a temperature programmed by the user. The burner is lit gradually by an electrical spark emitted by a spark plug connected to the electronic card, which in turn controls gas feed to the burner. As soon as the burner is lit, the electric current generated by the first spark plug is transformed by the ionization effect, changing the polarization of the current, which is detected by another spark plug that emits the change signal to the electronic card for further control of the heater.
