The definiens and working principle of controllable pitch propeller are introduced, the characters of CPP mechanism are summarized, and three types of shipping are concluded, which is applicable to equip with controllable pitch propeller by compared with pitch propeller. The control system of CPP usually adopts PID control, but the parameter of PID controller is adjusted inconveniently so as not to receive favorable result, therefore, the CPP control system based on fuzzy and neural network control is proposed so that improving the control effect. The result shows that the system design is feasible and effective.

At present, although finite element methods is a kind of effective measures in analyzing metal plastically forming problems with friction, dynamic friction in the process of metal forming is substituted with static friction and constant frictional force as one of independent constraint conditions is transposed to equivalent node-load or FEM unit is divided into contact unit and inner unit in numerous studys and applications, so that it result in relative bad accuracy and awkward operation. These defects mostly attribute to the fact that FEM bases on the variational equality principles, however frictional constraint will actually result in variational inequality energy functional.

The major findings are:⑴During the intelligence test for the three groups of students, for half of the students or most of the students their scores on the all-including scale, the language scale and the performance scale all increased to various degrees;⑵From the analysis of the relationship between intelligence and reaction time, it is found that the result of this study confirms the existing views that there is a negative correlation between intelligence and reaction time, and the negative correlation is more evident when it is choice reaction time;⑶Different motor skills have different influences upon children with lower intelligence. Though the difference is not large, the average increasing percentages in the sample T tests for the three groups before and after the experiment show that the effect of open motor skill is the best, that of the synthetic motor skill or the open-closed is the better, and that there isn't a marked change in the closed motor skill trainees;⑷While analyzing the result of the experiment, it is found that the scores on the performance scale are higher than the scores on the language scale, especially in the open motor skill group, which tells us that the intelligence improving effect of physical training is realized to a greater extent through increasing their performance abililty.

In respect that various requirements of load and temperature on different parts of the baker, firebrick lining was chose reasonably, and the dosage of light heat preservation brick is in enlargement. As a result of that, the weight of the furnace was decreased, and increased its performance of heat preservation and cumulation was increased consumedly. With the use of ""W"" type fire tunnel and straight-through dilatation joint, and two enlargement of the perpends on the wall appropriately, all the problems of heat preservation in the anode baker, uniform temperature in the tunnel, and its life span were solved effectively. In the research of anode blocks in and out of the furnace, and of tidying it up, the multi-function crane clamps was alented and the assembling unit was reconstructed, which made it easy to automatic ally assemble the carbon blocks of various specifications with only one set of assembling unit.In the aspects of automation, a new type pulse combustor and solid thermocouple, as a result of that, not only the control accuracy of the fire tunnel's temperature was increased, but also the system function was improned to be more dependable, safe and practicable.
