The invention greatly enhances the cruising capability of ships, avoids the occurrence of non-electric states, has high energy utilization efficiency, is safe and reliable and is beneficial to practical use.

The invention discloses a turbine device with variable flows. The turbine device provided by the invention comprises a volute, wherein the volute is provided with an air inflow path; the air inflow path is internally provided with a separation wall and a mobile baffle with an arc-shaped cross section; the mobile baffle can axially move along the volute in the air inflow path; one end of the mobile baffle extends out from one side of the volute and is connected with a control device of the mobile baffle in a transmission mode; when the other end of the mobile baffle moves to the other side of the volute, the mobile baffle is used for dividing the volute into an internal volute flow path and an external volute flow path which are not communicated mutually; and the control device of the mobile baffle drives the mobile baffle to move upwards in the spanwise direction of the volute so as to change the flow allocation proportion of the internal volute flow path and the external volute flow path. The volute is simple in structure, good in inheritance, low in cost and easy to quickly realize engineering, and can be used for solving the problems in reliability and efficiency of the existing variable geometry turbine-compressor with a vaned nozzle and the problem of lower efficiency of a variable geometry compressor without a vaneless volute.

The invention relates to a method for determining a state of charge of a battery system (10) having at least one battery cell (16) and an additional energy store (24), which is connected in series to the at least one battery cell (16) and can be switched on and off. According to the invention, the method comprises the following method steps: switching on the additional energy store (24); measuring the voltage of the additional energy store (24) at a predetermined time interval; -ascertaining a change in capacity of the additional energy store (24) on the basis of the measured voltage of the additional energy store (24) and a voltage characteristic curve; ascertaining a charging amount per unit time of the additional energy store (24) as a function of the ascertained change in capacity of the additional energy store (24); and ascertaining the state of charge of the battery system (10) on the basis of the ascertained charge amount per unit time.

The invention discloses a method for preparing whole wheat capable of being fed for cows and pigs, which belongs to the field of a feed technique, a microorganism technique and livestock breeding, and solves the problems that the wheat processing cost is high, the whole wheat cannot be digested when being fed for cows and pigs, and the price of corn rises, the feed cost is increased, and has no proper substitution. The method comprises the following steps: mixing the taken whole wheat, fresh distiller's grains and strain uniformly, keeping the moisture of a mixture to be 33-53wt%, bagging, sealing or storing in a cellar, carrying out anaerobic fermentation for more than 35 days, or carrying out anaerobic fermentation until pH value is 4.0-3.8. The method is simple to operate, and is easy for industrialization; the prepared whole wheat is not required to be crushed or grinded, can be fed directly or can be stored for a long time, and the cost is reduced by 17.4-43.5% compared with the cost of non-prepared whole wheat; the whole wheat can act as the unique refined supplementary food of beef cattle, can replace 50% of high productive diary cow refined supplementary food and 65% of concentrated feed for growth and fattening of pigs, and the feed cost consumed for weight increasing per unit / milk production can be greatly reduced.

The invention discloses a compound feed containing fermented cottonseed meal for chicken for eggs, and a preparation method of the compound feed. The compound feed comprises the following raw materials: corn, 46% of bean pulp, bran, fermented cottonseed meal, cotton kernel protein, peanut cake, mountain flour, calcium hydrophosphate, salt and gunk for chicken for eggs. The preparation method comprises the following steps of: weighing all of the raw materials according to percentage by weight; feeding the raw materials into a crusher to be crushed, wherein the crushing granularity is 20-30 meshes; feeding the materials into a pelletizer, wherein the pelletizing temperature is 75-80 DEG C, and the gelatinization degree is greater than or equal to 90%; and finely crushing, wherein the crushing granularity is 8-15 meshes. The compound feed has the beneficial effects that fermented cottonseed meal is adopted to take the place of a part of cottonseed meal, so that not only is the requirement of chicken for eggs on nutrition met, but also the production capacity of the chicken for eggs is improved; and in addition, due to the addition of Chinese medicine additives, the compound feed has both the medicine property and the nutrition, so that when the compound feed is used together with the main feed, the production capacity of the chicken for eggs is improved, and the immune function of the chicken for eggs is improved.
