Abstract: Artificial snow at ambient temperature is used for skiing and is composed of grains of artificial snow at ambient temperature that include magnetic solid grains. The producing method comprises the following steps: (1) using a crushing apparatus to crush a magnetic material into solid grains; (2) using a mesh sieve to sieve the solid grains at a certain particle size; and (3) bonding a layer of material capable of modifying surface property to the surface of the solid grains obtained from sieving. A trail comprises the artificial snow at ambient temperature.

Abstract: A locking apparatus used for controlling a movable chain, strip or strap-shaped object (71) comprising a support frame; a roll shaft (6) with a friction surface or a sprocket pitch slot (64), the roll shaft (6) being fixedly connected to a support rod (66), and one end of the support rod (66) being pivotally connected onto the support frame; a pawl (62) disposed above the roll shaft (6) and capable of rotating around one end; and a pressurization body (3) opposite to the roll shaft (6) along a transverse direction, thereby forming a roll gap between the roll shaft (6) and the pressurization body (3). The roll shaft (6) can freely rotate when the roll shaft (6) is in a middle state. When the roll shaft (6) is forced to downwards pivot until a ratchet disposed on a contact base (65) engages with a ratchet (6302) of the roll shaft (6) to prevent the rotation of the roll shaft (6), the object (71) can be locked.
