Research on Protection Control Device for the Vaporization of Cryogenic Liquefied Gas
If the liquefied gas is not fully vaporized when a cryogenic vessel is in use,liquid medium is allowed to flow into the room-temperature pipeline.The impact toughness of the vessel will be greatly reduced.This is hazardous to personnel and equipment.In this study,water between 0～4 ℃ was used to the experimental of protection control for the vaporization of cryogenic liquefied gas,investigated effect of regulating valve opening and output frequency of inventor on temperature changes.Thus,a new type of protection control device with high precision and stable data was designed.This device will allow greater safety and security in handling liquefied gas at cryogenic temperature.
The present invention is directed to phosphatidylinositol or lysophosphatidylinositol concentration indicators relates to efficacy evaluation method of a medicament having a therapeutic or prophylactic effect for a disease EL activity is associated. Further, the present invention relates to a kit for use in screening methods and method of the EL active inhibitors using phosphatidylinositol.
