The nonmetallic flexible pipe comprises, from the inside to the outside, an inner liner layer (1), a pressure bearing layer (2), an isolation layer (3), a stretch-resistant layer (4), a functional layer (5), and a protective layer (6), wherein two adjacent layers are non-rigidly bonded. The inner liner layer (1) is made from a thermoplastic polymer. The pressure bearing layer (2) is made from a fiber-reinforced resin-based composite material. The isolation layer (3) is made from a thermoplastic polymer. The stretch-resistant layer (4) is made from a resin-reinforced fiber material. At least one of an optical fiber, a cable, a heat tracing tape, a heat conduction medium conveying pipe, a pressure sensor, and a temperature sensor is provided in the functional layer (5). The protective layer (6) is made from a thermoplastic polymer. The nonmetallic flexible pipe has good corrosion resistance, gas permeation resistance, flexibility, temperature resistance, and pressure resistance. The invention can be adapted to poor working conditions in the ocean, and is applicable to marine risers and deep-sea pipelines.

A stable preserving microsphere catalyst can be obtained by inactivating the active center of the catalyst, wherein the calcination temperature, calcination time, calcination atmosphere should be controlled strictly. The stable preserving microsphere catalyst may be kept for a long time under room temperature, and can be activated in air or oxygen containing atmosphere before used in catalytic reaction. The catalyst obtained by the protection method has same activity for converting oxygen compound to olefine and selectivity as the fresh baked catalyst.

[Lixin TANG, Ying MENG] CN Shenyang A method for assigning surplus slabs in slab yards to orders includes loading slab pre-yards of a plurality of production lines with surplus slabs, describing the assignment of the surplus slabs to the orders with a mathematical model, grouping order data and slab data based on steel grades, obtaining an assignment scheme for the surplus slabs and the orders in each group with a mixed scatter search algorithm, and assigning the surplus slabs to the orders using the assignment scheme. If a surplus slab is in a pre-yard of a production line associated with an order the surplus slab is assigned to, the slab is moved using a crane to the production line. Otherwise, the slab is moved to the pre-yard associated with the production line, and then moved using a crane to the production line. The slab is then heated and rolled by the production line.
