At present, the massive use of traditional plastics which are very hard to degrade and hereinafter referred to as non-degradable plastics has caused serious pollution problems, which has a harmful effect on the environment and human health. Up to now, many countries have enacted strict policies and regulations to limit the use of non-degradable plastics, polyadipate/butanediol terephthalate (PBAT), as a kind of degradable plastic, has drawn more and more attention. In this paper, research progress on the degradation of PBAT is reviewed and the market dynamics of PBAT are introduced. In the next few years, the global capacity of PBAT is surging and is mainly concentrated in China. The prospect of PBAT is discussed which may provide a reference for PBAT producers.

In the offshore cluster pattern adjustment well operation, casing-opening sideslapping technology can save time and cost by using the original well groove and the old hole section. It has become one of the conventional means to tap the potential of the old well area. In casing-opening operation, the difficulty of milling 13-3/8 "casing is higher than that of other casing sizes. The main reason is that the wall thickness of casing and the window length are relatively long, and the wear of shoes in actual operation is also larger than other sizes. The 13-3/8 "casing window opening of Qikou 17-2-4DH1 well adopts Weatherford's new type of fast one-run window opening tool with carbon tungsten carbide cutting block for shoe grinding. Meanwhile, window opening parameters and window repairing parameters are optimized, so that the whopper, window opening and geological guide drilling can be mounted in one trip, and the passability of the window can be ensured. It provides an effective technical practice for the sidetracking of 13-3/8 "casing in the future.

In order to explore the strategy on urban energy and reduction of greenhouse gas, a large number of energy models have been developed by interdisciplinary studies. Mixed patterns are particularly useful as a result that they incorporate more dynamics to simulate the relevant high-level decisions and the provided actual results by building-level factors. However, space and spatial energy models are not often linked, which ignores the spatial impact of energy and emission policies in urban environments. The application of this method shows how it can be used to assess how different policies interact with other and affect building energy needs and greenhouse gas emissions.

In recent years, more and more researches and reports on nanofluids have been made, and hybrid nanofluids as new fluids have gradually entered the field of vision. Hybrid nanofluids have many excellent properties at the same time. Because the stability of hybrid nanofluids has an important influence on the thermal properties and flow heat transfer properties of the solution, the stability of nanoparticles suspended in the base liquid has become an important direction of research. The stability of graphene oxide-Al2O3 hybrid nanofluids was studied with ultrasonic time, dispersant and ultrasonic power as variables. The experimental results show that when the ratio of graphene oxide: Nano-Al2O3: dispersant is 1:1:1, ultrasonic time is 2 h and ultrasonic power is 300 w, the stability of graphene oxide- Al2O3 hybrid nanofluid solution is the best.
