- bubble rise time 气泡上升时间
- Hold in both hands with double handgrip bubble rise wash a face, wash 1 minute. 用双手把泡沫捧起来洗脸，洗1分钟。
- When water boils, bubbles rise to the surface. 水开时, 水面起了泡泡。
- An amplifier with very wide frequency response which can amplify pulses without distortion of the short rise time of the leading edge. 频率响应极宽的一类放大器，可以无畸变地放大前沿上升时间短的脉冲。
- Thus, even large values of capacitance shunting the input will have negligible effect on rise time. 所以，即使并联在输入端的电容很大，其对上升时间的影响也很小。
- Improved insulation protection against transient spikes, high frequencies, and short rise time pulses without increasing insulation thickness. 在不增加绝缘厚度的情况下,提高了抗瞬间冲击、耐高频性、耐陡升脉冲性。
- As water begins to boil, bubbles rise ever faster to the surface. 当水开始沸腾时,气泡会更快地升向水面。
- The light, fragile bubbles rise to a fine, smooth foam. 轻盈的汽泡上升后形成圆润，柔滑的泡沫。
- The measurement results show that the rise time is about 2.58ns and the decay time is about 55 ns of the EMP simulator output waveform. 测量结果表明此电磁脉冲模拟器可以输出前沿大约为2 58ns、衰落时间约55ns的双指数脉冲波。

- They watched long and wonderingly for him to come up, but not even a bubble rose on the quietly ebbing tide. 他们好奇地注视了好久，等候他浮上来，但是在那缓缓退落的海潮面上连个水泡儿也没浮起。
- Rise time in a feedback picoammeter is a function of the physical or stray capacitance shunting the feedback resistance (RFB). 反馈型皮安计的上升时间是反馈电阻（RFB）上并联的物理电容或寄生电容的函数。
- Due to the high degree of voltage amplification, this stage regenerates the voltage swing and the rise time of the incoming signal. 因电压放大的高倍数，这一级一则改变输入电压的摆幅，二则改变引入信号的上升时间。
- We saw bubbles rising from under the water. 我们看到一些水泡从水下升起。
- The rise time of a feedback picoammeter is normally limited by the time constant of the feedback resistor (RF) and any shunting capacitance (CF). 反馈皮安表的上升时间通常受反馈电阻器（RF）和并联电容（CF）形成的时间常数的限制。
- A bubble rises because its density is less than that of the soft drink. This buoyancy increases as the bubble grows Archimedes Principle. 由于气泡的密度比周围的汽水低,气泡会上升,而浮力会随著气泡变大而增加阿基米德定律。
- Pulse power with fast rise time technology was applied in many fields such as nuclear physics, electron beam, accelerator, laser, HPM etc. 高压大电流快脉冲技术在核物理技术、电子束、加速器、激光、HPM等许多现代科学技术领域都有广泛的应用。
- Used in Electronic lighting ballasts and High voltage power Supplies of High frequency and High pulse rise time circuits. 适用于电子镇流器和电源开关等高频脉冲和高频振荡电路中。
