负号

When we are dealing with arithmetic, we should be very careful about minus.

当我们在做算术的时候，我们要特别小心负号。

You may have noticed how, for the vertical scale, a negative sign is used.

您可能已经注意到如何为纵坐标，一个负号被使用。

The negative sign means that energy is transferred from the oscillator to its environment.

负号的意思是能量由谐振子传递到它的环境。

And - are, respectively, the positive and negative sign s.

和-是正号和负号。

Note the negative sign in expression 1-1 which indicates that the examples all invert the signal pattern when amplifying.

注意，表达式 1-1 中的负号说明，示例中的电路在放大时改变了信号的极性。

Use a negative sign to show that the value is less than zero.

用负号 表示数值小于零。13。名词否定词，否定语

Applies the Number format with two decimal places, thousands separator, and minus sign for negative values.

应用带两位小数位，使用千位分隔符且负数用负号表示的"数字"格式。

According to what graph 2 shows, conductor is still, uniform static magnetic field moves to the left at the speed of , referring to in graph 1 can get , substitute it into Lorentz magnetic force , it is , the negative sign here is not added randomly, it is because the moving direction of magnetic field is opposite to the moving direction of conductor.

如图2所示，导体是静止的，均匀的静态磁场以速度向左边运动，对照图1的，就得，带入洛伦兹磁力中，有，这里的负号不是随意加进去的，而是由于磁场的运动方向与导体的运动方向相反之缘故。

Negative sign symbol:~~Tap a symbol to indicate negative numbers.

The measurement beam travel through the half circular polariscope and rotating analyzer to generate a measurement signal. As these two signals are guided into the lock-in amplifier, the phase retardation of the waveplate can be obtained.

由於锁相放大器所显示的相位延迟量在-180°~180°范围内，超出此范围则会产生误判，因此加入波长位移的技术，透过波长改变前后所产生的相位延迟量变化差值，可由此差值之正负号确定波板慢轴方向。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.

在大学的三年的学习生活不仅给予我自身的充实，更重要的是磨练和培养了我较强的自觉能力和严谨，踏实的作风以及不怕困难的精神，对未来充满了信心！
