Summary This paper analyzes the working principle and stability of a transistor mul- tivibrator operating as a frequency divider,with both sides being synchronized by the input signal.It is found that the frequency division stability of this circuit can further be increased when the multivibrator operates in the second class of oscillating condition,and that the optimum operating point is best determined from the actual base voltage changing characteristic.

因此偏置点的位置能够随着偏置方向曲面法曲率的变化自适应地调整。

Heat-treating within the temperatures range 700 to 800℃, the transition temperature of heat-treated C-glass became higher with increasing heat-treatment temperatures and gradually approached the transition temperature of the B-glass without TiO〓; the appearance of the C-glass gradually changed from brown-violet colour to intense blue-violet colour and even to opalescence; and the phase separation morphology of TiO〓-rich phase gradually changed from an interconnected phase to a siliceous droplet phase embedded in SiO〓-rach matrix phase with increasing the heat-treatment temperatures.

在玻璃的转变点附近的温度范围内热处理含TiO〓系统玻璃时，随热处理温度的升高，玻璃的转变温度增大，逐渐向不含TiO〓的MgO-Al〓O〓-SiO〓系统玻璃的转变温度靠近；玻璃的颜色逐渐由紫色向兰色及乳白色转化，这是分相玻璃中两相组成在热处理过程中的变化所引起的。
