查询词典 decibels

It is customary to plot the amplitude ratio in decibels and the phase angle in degree against the common logarithm of the input frequency.

在绘图时通常幅值用分贝表示，相角用度表示，输入信号的频率按常用对数取值。

In general, echolocation calls are characterized by their frequency, intensity in decibels, and duration in milliseconds.

一般来说，用于回声定位的叫声是用它们的频率、强度以及持续时间来表示特征的。

Solved effectively to shed off the phenomenon inside the outside layer.2 The super mute hangs the round, gliding the hour to almost has no sound, the voice is is small in 10 decibels.3 Make use of the high accuracy number controls the creation of process the equipments, guaranteeing to hang one side of the body four-wheeler, being subjected to the dint even, push to pull to have no damage 100,000 times.4Hanging patch nail is made of steel, L-shaped lateral positioning hanging piece; rapid and easy installation.

有效解决了内外层脱落现象。2 超静音吊轮，滑动时几乎没有响声，声音小于10分贝。3 运用高精度数控加工设备的制作，保证了吊体四轮一面，受力均匀，推拉10万次无损坏。4 挂片采用加硬冷轧钢材制作。 L 形侧向定位挂片，安装快捷，轻松。

That's about 10 decibels lower than a jet engine.

这是10分贝比喷气发动机低。

This is a logarithmic scale which means that increasing the number of decibels corresponds to a multiplication of intensity.

分贝单位是对数比例，是音量的度以倍数选进。

Noise is measured in decibels on a logarithmic scale (such that a doubling of sound energy equates to a 3 decibel increase).

噪音分贝来衡量，就对数规模（例如，一个翻一番无害的能源相当於3分贝增加）。

Has the scientist to do the experiment: When noise intensity when 90 decibels, in retina's rod cell difference radiance's sensitivity starts to drop, distinguishes the time which the weak light responded also to lengthen; When noise when 95 decibels, some 2/5 person mydriasis; When the noise amounts to 115 decibels, the eye reduces 20% to the radiance compatibility.

有科学家做过实验：当噪音强度在90分贝时，视网膜中的视杆细胞区别光亮度的敏感性开始下降，识别弱光反应的时间也延长；当噪音在95分贝时，有五分之二的人瞳孔放大；当噪音达到115分贝时，眼睛对光亮度的适应性降低20%。

And these emit…150 decibels over a distance of about a nautical mile….

150分贝以上的距离大约海里。。。

The tavern had been dark and passably cool, with the front door open and big fans on the ceiling and one on a stand by the door whirring at about a hundred and five decibels.

小酒馆很暗，还算凉快，前门开着，天花板上有大电扇，还有一台立式电扇在门口以105分贝的响声转着。

Power parts: motor 0.8 kilowatts,(the most energy-efficient textile machinery) Use of floor type, in the past motor installed in the wall due to power large central power-particularly prone to vibration force, causing a long time in different parts of the rack screws loose, resulting in glitches and instability caused by take-wai (3) Weft parts: the reference to a high-speed rapier looms used Chuanjian round, narrow tracks, narrow sword belt, reducing machine noise, so that the warp to reduce significantly reduced contact surface the warp yarn breakage improved product quality and quantity; and reducing machine noise below 70 decibels more than the requirements of the State Environmental Protection 100 decibels.

动力部分：电机0.8千瓦，采用落地式，以往电机装在墙板中部开机时由于动力较大特别容易产生振动力，时间长造成了机架各部位螺丝松动，产生小故障且造成接纬不稳定（3）引纬部分：引用了高速剑杆机采用的传剑轮，窄轨道，窄剑带，降低了整机噪音，使经纱接触面减少明显减少了经纱断头提高了产品质量和数量；且降低了整机噪音70分贝以下超过国家环保100分贝的要求。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。
