An analog control, in accordance with corresponding changes in the load modulation transistor gate of the base or bias, to achieve the output transistor switching power supply or transistor turn-on time of change in this way can the power supply output voltage in the workplace Conditions of constant change.

一种模拟控制方式，根据相应载荷的变化来调制晶体管栅极或基极的偏置，来实现开关稳压电源输出晶体管或晶体管导通时间的改变，这种方式能使电源的输出电压在工作条件变化时保持恒定。

Then, the system life predication method and the Reliability distribution method of system is presented.

针对目前大部分零件的寿命试验数据都是在恒定交变载荷下取得的情况，结出了载荷相关的系统可靠性分析方法。

The plane's cabin failed to pressurize and the jet had to land in Seattle.

由于飞机机舱无法保持恒定气压，该喷气式客机不得不在西雅图着陆。

A pressurizer is used to maintain a constant primary system pressure.

加压器用来维持一个恒定的主系统压力。

Constant primary winding current independent of load level is inherent in the proposed system so that power could be transmitted from power source to load in a stable manner.

额定频率下系统一次侧线圈电流保持恒定而与负载大小无关，保证电能由电源向负载的稳定传输。

However, the pseudo-triaxial strengths of several rocks from the best fitting solutions have great scatterness from the real magnitudes. Also, it does not correspond to the experimental results that rock has the same strength under conventional triaxial compression and tension; the maximum increase of strength from intermediate principal stress has a linear relation with the minor principal stress; and the first-order derivative of strength has an interruption at the peak point.

此外，统一强度理论认为岩石三轴伸长强度与常规三轴压缩强度相同，在最小主应力恒定时中间主应力引起的强度最大增加值随最小主应力线性增加，且强度关于中间主应力的一阶导数在峰值点是不连续的，这些都与试验结果不能完全协调。

According to More Effect,when the Hore component is placed in a gradient field,at the same time the direction of the current is perpendicular to the direction of the voltage,then between the two parallel side face come out the Hore voltage. When Hore component is set in this kind of uni-gradient magnetic field and the electric current is unchanged,the voltage output of Hore component will be proportional to the position of the Hore component in the magnetic field.

根据霍尔效应可知，置于磁场中的霍尔元件若电流方向与磁场方向垂直，则在霍尔元件垂直于磁场和电流方向的两个侧面将产生电势，将霍尔元件置于强度随空间位置线性变化的磁场中，且控制电流恒定，输出就正比于霍尔元件处于磁场中的位置，因此可以用霍尔元件来测量磁场与霍尔元件间的相对位移量。

Moreover, they are completely reliable, since tidal power comes from the constant pull of the Moon which tugs the tide up or down every 12 hours.

此外，它们是完全可靠的，因为潮汐能来自月球恒定的引力，月球每 12 小时吸引潮水涨或落一次。

The first deceleration phase of motion and the over-corner P-H curve constructed for regions with sharp corners are devised by quadratic and constant velocity interpolation algorithms, respectively.

第一阶段的减速运动和过度角落PH值曲线构建区域急剧角落设计的二次和恒定速度插补算法分别。
