The anti-jam indicating plate for the highway is capable of, through installing a driving gear block and a transmission gear block, achieving the effect of picking up the indicating plate by using an impact force of heavy rain and hailstone in severe weather of the heavy rain and the hailstone, and through installing a driven gear plate and a buffering plate, achieving the effect of shielding and protecting the indicating plate, picking up and protecting theindicating plate through using the impact force of the heavy rain and the hailstone, achieving the effect of protecting the indicating plate in the severe weather so that the indicating plate is not damaged, and achieving the effect of improving service life of the indicating plate through protecting the indicating plate in the severe weather, thereby achieving the effect of conveniently and continuously performing indicating work on the highway for a long time.

The invention relates to a method for improving the mechanical properties of an amorphous endogenous composite material through recovery of an amorphous matrix structure, and belongs to the field of amorphous alloys and endogenous composite materials. The microstructure characteristics of this kind of amorphous endogenous composite material are: the endogenous crystalline phase with reversible phase transition is distributed in the amorphous matrix. Under tensile loading, such amorphous endogenous composites exhibit superelasticity, i.e. complete shape recovery after small strain unloading. Through tensile cyclic loading at small strains, the amorphous matrix phase in the amorphous endogenous composites undergoes structural recovery driven by the "shape memory effect". The structurally restored amorphous matrix can lead to a significant improvement in the mechanical properties of amorphous endogenous composites, including improved tensile plasticity and prolonged work-hardening stages. This method can improve the mechanical properties of the amorphous endogenous composite material, and then expand its practical application as a structural material, which has important social and economic benefits.

The present application relates to a method for determining the scavenging activation working condition of a supercharged direct injection engine, and relates to the field of engine control. This determination method includes firstly determining the scavenging request working condition of the supercharged direct injection engine, and secondly determining the scavenging allowable working condition of the supercharged direct injection engine. If the supercharged direct injection engine only meets one of the scavenging request conditions or the scavenging allowable conditions, the supercharged direct injection engine will be further judged. Whether the corresponding process control is within the control of the scavenging activation condition, if so, activate the supercharged direct injection engine for at least the first preset time T1 and then exit the scavenging activation condition, if not, then activate the supercharged direct injection engine The engine immediately exits the scavenging request mode. The determination method provided in the present application solves the problem of excessive discharge and exhaust temperature caused by unreasonable scavenging in the related art.

The invention discloses a foldable flexible lifting mechanism of a vehicle body correcting machine. The lifting mechanism comprises a rear lower arm, a rear upper arm, a front lower arm, a front upper arm, a parallelogram leveling mechanism, a rear oil cylinder and a front oil cylinder, wherein the rear lower arm and the rear upper arm are hinged with eawch other and have the same length; the front lower arm and the front upper arm are hinged with each other and have the same length; the distance from a hinged point of the leveling rod and the rear upper arm to a hinged point of the leveling rod and a platform is equal to that from the hinged point of the leveling rod and the rear upper arm to a hinged point of the rear upper arm and the platform; the rear oil cylinder and the front oil cylinder have the same working stroke and initial and final setting positions of the working stroke, work at the same speed and drive the platform to lift through a lever arm and front and rear upper support arms. By adopting the arrangement of the foldable support arms, not only can rigid fixed-point vertical lifting be achieved, but also flexible low-position tilt descending can be achieved.
