A pertinent study and its result obtained from calculation in the computer DJS 131 shows that the relative value method for selection of the optimal value, which was widely adopted by J1M3 and KT3 in the Soviet Union and by some domestic works concerned is not optimum to the actual system, even though it is valid mathematically.

An improved way be select the optimal value of the secondary impulse pressure in the control system of steam turbine is discussed in the paper. A pertinent study and its result obtained from calculation in the computer DJS 131 shows that the relative value method for selection of the optimal value, which was widely adopted by J1M3 and KT3 in the Soviet Union and by some domestic works concerned is not optimum to the actual system, even though it is valid mathematically. In this paper an absolute value method for selection of the optimal value is recommended. It is not only valid mathematically, but also optimum to the actual system. If the new method is applied in the control system design, the sensitivity of the pilot value may be increased by about 30% without any extra charges and the dynamic behaviour of the control system will be also improved.

The effects of the first two factors on the dispersiveness are emphasized in this paper. Under our processing condition, we found the optimal pre-dispersing time for γ—Fe_2O_3 powders ranging from 12 to 16 hr, the optimal value of the entire dispersing time from 64 to 72 hr.

The factors affecting the dispersiveness of magnetic dispersions are the characteristics of magnetic powders, the dispersing time and the processing technique. The effects of the first two factors on the dispersiveness are emphasized in this paper. Under our processing condition, we found the optimal pre-dispersing time for γ—Fe_2O_3 powders ranging from 12 to 16 hr, the optimal value of the entire dispersing time from 64 to 72 hr. The disper siveness of magnetic dispersions can be characterized by squareness ratio and the half peak width of derivative curve of magnetic loop.

影响磁浆分散性的主要因素是磁粉特性、磁浆配方、制备工艺和分散时间等。本文研究了磁粉特性,分散时间对磁浆分散性的影响。认为,在我们的制备工艺条件下,普通γ—Fe_2O_3磁粉的最佳预分散时间是12—16小时,最佳总分散时间是64—72小时。并且认为,判断磁浆分散性的特性参数是它的矩形比K,丰峯宽度△H,显微镜观察是定性观察分散性的有效手段。
