The invention discloses an environment-friendly and energy-saving integrated cast-in-situ lightweight concrete wall and a construction method thereof. The wall comprises a wall body made from formwork cast-in-situ lightweight concrete, and tie bars. The tie bars are arranged on structure columns at the two ends of the wall body and located on a structure beam on the top of the wall body and anchored in the wall body. Wire boxes and pipelines are embedded into the wall body. Holes and door and window holes are reserved in the wall body. The cast-in-situ process is adopted, construction is convenient and rapid, the flatness of the wall obtained after formwork removal is high, plastering is not needed, rendering is avoided, and building rubbish is reduced. The wall is high in strength and capable of being suspended, bolts can be directly embedded, the problems that formwork collapse is caused by too high lateral pressure during vertical pouring of foam concrete, and layering non-uniformity is generated due to sedimentation are solved, one-time pouring can be achieved for the wall with the vertical height of 3-4 m, the whole construction process is shorted by almost half compared with the brick laying construction period, construction efficiency is improved, engineering management cost is reduced, the rate of return on investment is increased, and good economic benefits and social benefits are achieved for enterprises.

The invention provides a continuous hydrolysis process for preparing glyphosate by a glycine method. The process comprises following specific steps: (A) conveying a condensation reaction synthetic solution into a mixing reactor by a pump and controlling a material temperature to be lower than 55 DEG C to finish an acid adding and neutralizing process; (B) carrying out gas-liquid separation on materials discharged by a heat exchanger and enabling condensed gas and liquid to respectively enter a methylal recycling tower to recycle methylal; (C) enabling kettle bottom liquid discharged from the methylal recycling tower to enter a methanol recycling tower to recycle methanol; enabling kettle bottom liquid discharged from the methanol recycling tower to enter a hydrolysis tower to finish a hydrolysis reaction; and (D) carrying out flash evaporation on kettle bottom liquid discharged from hydrolysis tower; removing water and acid and enabling the kettle bottom liquid enter a crystallization kettle; and cooling and crystallizing under agitation to obtain the glyphosate.

The invention discloses a method for preparing foundry coke, employing blind coal as stock, disintegrating it separately into three grade size: 1~3mm, 0.18~1mm, <0.18mm, for reservation. Adding coal pitch and coal tar as adhensive, filling the mixing and kneading pot with the said three blind coal, stirring at the temperature 110~130 DEG C for 10 minutes, adding the fused coal pitch and coal tar into the mixing and kneading pot, stirring for 10 minutes. Employing pair roller forming or press forming to the mixed and kneaded sample for forming, then setting for 24 hours, for reservation. Feeding the retort with formed sample for warming-up and charring, covering the surface of the sample with pulverized coke for air insulation and avoiding oxidization; cooling in natural way after charring to normal temperature, removing the pulverized coke, fetching it out and getting the needed product.

The invention discloses a method for achieving an anti-snaking broadband energy absorption mechanism and an optimal configuration method for the parameters of a bogie. According to the method and the optimal configuration method, a dynamic design method is mainly applied, and lead-lag correction of unstable snaking oscillation phenomena of the bogie is achieved in a self-adaptive control manner; an anti-snaking redundant design form of an ICE3 prototype is borrowed, the anti-snaking broadband energy absorption mechanism is achieved through combination application of novel anti-snaking vibration reducers, and the method and the optimal configuration method are simple and applicable; and an anti-snaking soft constraint or anti-blocking technology is borrowed, the hydraulic rigidity is properly reduced, and rheology nonlinear influences are avoided. By means of the method and the optimal configuration method, the design defects of the ICE3 bogie prototype are overcome, a high-speed-rail passenger-dedicated development manner is gradually changed, and then the rate of return on investment is increased; in addition, the adaptability and the friendliness to track lines are improved, and the railway construction investment cost can be saved; and meanwhile the robustness of perturbation or disturbance of natural factors is improved, and particularly when the method and the optimal configuration method are used for mountain lines, and the structural technical service cost can be obviously reduced.

The invention relates to a lease exchange method for leased containers, wherein the lease exchange method for the leased containers can be used by multiple leasers on a network platform. The lease exchange method for the leased containers comprises the following steps: an interface is provided, wherein the interface is used by the multiple leasers for entering the information of at least one container which the leasers want to exchange and a storage place of the container on the network platform respectively; then, whether the containers of different leasers accord with exchange terms is judged through comparison according to the entered information of the multiple leased containers; if the containers of the different leasers accord with the exchange terms, the multiple containers which accord with the exchange terms are exchanged with equal quantity for lease, and therefore all the leasers can lease the exchanged containers.

The invention discloses a fan motor blade made of different aluminium casting alloys, belonging to the field of wind power generation equipment parts. The operational performance of a long blade cast from a single aluminium alloy material can be influenced. The invention has the characteristics that the blade is divided into at least two parts which are made of different aluminium casting alloys,every adjacent two parts form a fusion area which constitutes the aluminium casting alloys of the two parts, so that different parts of the blade have different properties and can satisfy the needs for the operation of the long blade.

The embodiment of the invention provides a large data file exchange method. The method comprises the following steps: a sender splits a large file into small data packets; the small data packets obtained from splitting are sequentially exchanged, a data abstraction layer is created, and the attribute information of each packet is recorded in the data abstraction layer; and after receiving all the split data packets, a receiver groups the packets according to the attribute information recorded in the data abstraction layer to recover the large file. By adopting the large data file exchange method provided by the embodiment of the invention, big data exchange in a heterogeneous environment can be realized.
