Field multifunctional insect detaining and collecting test tube device

The invention discloses a field multifunctional insect detaining and collecting test tube device. One end of an insect detaining tube is open, the other end of the insect detaining tube and the top end of an insect storage tube are in threaded connection, and the bottom end of the insect storage tube, a ventilating screen and a generator are in threaded connection. An opening and closing baffle is arranged in the insect detaining tube, the ventilating screen is arranged at the joint of the insect storage tube and the generator, a ventilating screen hole plate is arranged on the ventilating screen, small screen holes are formed in the plate, and cotton is placed in the generator. The device has the advantages that all the parts are convenient to detach and replace; re-escape of insects is effectively avoided; drop resistance is achieved, and it is avoided that the appearance integrity of small insects is damaged due to the fact that plastic materials generate static; the insects in the tube can be paralyzed through alcohol gas to be in a coma, the active degree of the insects is reduced, limb damage and deficiency caused by space competition fight among the insects are reduced, DNA of insect specimens saved after alcohol fumigation is not prone to degradation, molecular relevant experiments can be carried out, and meanwhile later insect shape classification work is also promoted.

Method for preparing lithium ion battery pack

The invention provides a method for preparing a lithium ion battery pack, and the method comprises the following steps: carrying out vacuum drying on a plurality of assembled lithium ion batteries, injecting part of electrolyte, carrying out constant-current charging to a first preset voltage, and carrying out constant-voltage charging at the first preset voltage until the charging current is lower than a cut-off current, performing constant-current charging on the battery to a charging cut-off voltage, measuring the surface temperature of the battery, and recording the charging electric quantity of the battery voltage rising from the first preset voltage to the charging cut-off voltage for the first time; determining to inject a first supplementary electrolyte or a second supplementary electrolyte according to the temperature value; recording the charging electric quantity of the battery voltage rising from the first preset voltage to the charging cut-off voltage for the second time, and recording the capacity of each battery; and assembling the batteries of which the difference percentage of the charging constants and the capacity difference percentage are within preset values into one group to form a battery pack. The battery pack prepared by the method disclosed by the invention is high in service life performance and good in consistency between single batteries.
