The invention relates to a composite for diagnosing a human body or an animal body, namely, an efficient Gd-loaded liposome preparation and a preparation method thereof. The liposome preparation is prepared from the following components in parts by weight: 30-80 parts of paramagnetic Gd contrast agent, 250-500 parts of lecithin, 50-200 parts of liposome stabilizer and 200-600 parts of buffer solution, based on the weight of metal Gd. The Gd-loaded liposome is prepared by using a phospholipid gel method, and the Gd-loaded amount of the liposome prepared by the method is high, thereby effectively delaying the retention period of the contrast agent in the body; and the liposome is good in storage stability.

Принадлежит:

The invention discloses a one-machine two-charging structure charging pile instantaneous switching over-current suppression method based on a delay switching strategy, and relates to a charging pile switching control strategy. A control object structure comprises a charging device module capable of providing services for two electric vehicles at the same time, a battery voltage acquisition module, a delay operation module and a relay switching control module. When the charging device is in a charging switching state of the two electric vehicles, the voltage difference between the batteries of the two electric vehicles is monitored through the battery voltage acquisition module, and when the voltage difference exceeds a certain threshold value, the output value of the delay operation module is increased to increase the switching time difference of the relays on the input sides of the two groups of batteries; therefore, the instantaneous overcurrent caused by the parasitic capacitance of ...
