The invention relates to a production method of midbodies of sterides drugs, in particular to a method for preparing dehydroepiandrosterone by microbial fermentation. The method includes the following steps of firstly, protecting three hydroxy of sterol to obtain protections; secondly, fermenting the protections by bacterial strain Mycobacteriumsp.NRRLB-3683 or 3805; thirdly, hydrolyzing a target object; and fourthly, purifying. The invention further provides a new path for preparing dehydroepiandrosterone from plant sterol, production cost of dehydroepiandrosterone is greatly reduced and quality yield of the dehydroepiandrosterone is improved.

The invention discloses a vehicle control system of a blade electric vehicle and a blade electric vehicle structure. A battery high-voltage insulation detection unit and a high-voltage loop interlocking unit are introduced into a high-voltage safety management module, and a vacuum brake assisting module is set, so that the electricity consumption and safety properties of the vehicle are largely improved. An energy recovery unit is implanted in a drive management system, recoverable energy is generated when the vehicle slides or brakes, the energy utilization rate is largely improved, and the cruising capacity of the vehicle is improved.
