[Problem] To enable reduction of an oppressive feeling that an operator sitting on a driver's seat feels from an engine room and relaxation of a restriction to rearward visibility of the operator sitting on the driver's seat. [Solution] The present invention is a hydraulic excavator which comprises a rotating body (2) and a working device (34) mounted on the rotating body (2), is arranged with an operator's cab (7) having a rear window (16) at a forward position of the rotating body (2), and is arranged with an engine room (9) at a rearward position adjacent to the operator's cab (7), the engine room (9) having a ceiling portion configured from a cover member (17), wherein a portion of the cover member (17) located in the vicinity of the operator's cab (7); is configured from a surface-shaped part having a shape gradually increasing the height toward the rear of a vehicle body with the vicinity of a lower end part (16a) of the rear window (16) as a starting point (18a) between a predetermined distance from immediately behind the operator's cab (7), e.g., an inclined surface part (18). For example, the height of the starting point (18a) of the inclined surface part (18) is set to be equal to or less than that of the lower end part (16a) of the rear window (16).

The invention discloses a method for producing a geopolymer binding material by red mud and the geopolymer binding material. The method comprises the following steps: (1), the red mud is evenly mixed with hydroxide of alkali metal or carbonate, and 3 to 5 mol of alkali metal is contained in the hydroxide of alkali metal or the carbonate, which is added into the red mud per kilogram; (2), the mixture is calcined for 1 to 3 hours at the temperature of 700 DEG C to 900 DEG C, and a heat-alkali activated red mud is obtained after cooling; (3), the activated red mud is mixed with granulated blast-furnace slag powder according to the mass ratio of (1.5:1):(4:1). When being used, the geopolymer binding material produced according to the method is evenly mixed with water with the mass ratio of 60 percent to 70 percent so as to achieve maintenance formation. According to the invention, waste material red mud produced by using Bayer processes largely is environmentally friendly and low in cost. The geopolymer binding material can be directly added with water to stir during the use, alkaline boosters such as water glass and the like are not required to be added, steaming and pressing or dried formation are not required, the use is convenient, and the adaptability is good.

According to the present disclosure, a train comprising one or more locomotives coupled to one or more tenders, which contain at least one of an exhaust after-treatment or a waste heat recovery system and optionally one or more other locomotive subsystems, such as dynamic braking, energy storage, driven wheels, and fuel storage, is provided. Accordingly, the present disclosure may have one or more of the following advantages: a tender to house an exhaust after-treatment system thereby easing space constraints on the locomotive power traction car. Additionally, said tender may include a large fuel tank, waste heat recovery system, and energy storage, thereby providing the means to substantially decrease fuel consumption or increase power, both with the option of switching to a different fuel source.

[Problem] To enable reduction of such a feeling of oppression that an operator sitting on an operator's seat is oppressed by an engine room and relaxation of restriction on a rearward visual field of the operator sitting on the operator's seat. [Solution] The invention provides a hydraulic excavator including: a revolving upperstructure 2; a working device 34 attached to the revolving upperstructure 2; an operator's cab 7 which has a rear window 16 and which is disposed in a front position of the revolving upperstructure 2; and an engine room 9 which is disposed in a rear position adjacent to the operator's cab 7 and which has a ceiling part made of a cover member 17; wherein: a part of the cover member 17 located near the operator's cab 7 is made of a face shape part, i.e. an inclined surface part 18, having a shape whose height gradually increases toward the rear of a vehicle body with the vicinity of a lower end part 16a of the rear window 16 as a start point 18a during a predetermined distance immediately after the operator's cab 7. For example, the height of the start point 18a of the inclined surface part 18 is set to be equal to or lower than the height of the lower end part 16a of the rear window 16.

The invention discloses a weather forecast method, device, computer equipment and storage medium, and belongs to the technical field of weather forecasting. According to the predicted longitude and latitude, the corresponding topographic and topographic features are searched; the data is sampled according to the data distribution as the training data set of the model; feature variables; use a parameter search tool to perform model hyperparameter search on the feature variables to obtain optimal hyperparameters; perform model training according to the optimal hyperparameters and the training data set to obtain a prediction model; receive real-time weather forecast messages As prediction data; using the prediction model and the prediction data, weather forecast prediction is performed.

The invention belongs to the field of tobacco processing, and in particular relates to a method for improving the quality of tobacco stems. The method comprises the steps of tobacco stem washing, ozone treatment, far-infrared irradiation, stem storage and the like, during which biological enzyme treatment is combined. By adopting ozone treatment, far-infrared radiation and enzymatic treatment with biological enzymes, this application makes full use of the internal changes of the tobacco stems after ozone, far-infrared radiation, and enzymatic hydrolysis, and better improves the internal quality of the tobacco stems. Specifically, this method can increase the content of total sugar and reducing sugar in tobacco stems, improve the softness of cigarettes, reduce the irritation of cigarettes, and reduce the tar content of smoke, thereby improving the internal quality of tobacco leaves. It has certain advantages in the production of cigarettes. promotion and application value.
