查询词典 magnitude

The magnitude scale is really comparing amplitudes of waves on a seismogram, not the STRENGTH of the quakes.

译：震级的值以地震记录仪上地震波的最大振幅为依据，而不是表征地震波释放的能量。

At this magnitude, it is the second largest earthquake ever recorded on a seismograph.

这种强度，曾经在地震仪的记录上，是强度第二大的地震。

In order to take advantage of the growing number of globally distributed seismograph stations, new magnitude scales that are an extension of Richter's original idea were developed.

为了更好的利用世界各地不断新建的地震检测站，在里查德原有理论的基础上扩展出了一套新的等级划分。

Probably the best-known gauge of earthquake intensity is the local Richter magnitude scale, developed in 1935 by United States seismologist Charles F.

或许最著名的地震强度测量是区域里氏震级，是由美国地震学家查尔斯·里希特1935年确立的。

Although changes in ground water have been observed before and after earthquakes, they don't "give you very useful information about magnitude, location and time," said David Booth, senior seismologist at the British Geological Survey, who said he had not read Claesson's research.

英国地质调查局的地震学家戴维·布斯对这一研究的前景并不乐观。他说，尽管地下水的化学成分在地震前后发生了变化，但是这并不能"给你诸如地震强度、方位和时间等非常有用的信息"。

An earthquake with a magnitude of less than 2.0 is so slight that usually only a seismometer can detect it.

小于2.0震级的地震非常轻微，通常只有地震检波器才能探测到。

In terms of the documentation frequency of these historical data on earthquakes of 4.7 magnitude or above in the past 3000 years ( Table 5 ) the frequency was below 2 times per 10 years for most of the time before the Song Dynasty; when printing was invented in the Song Dynasty the frequency increased to 3 times per 10 years; after the invention of seismoscope in 1900 it reached 100-1000 times per 10 years.

从3000年来4.7级以上的(ji2 yi3 shang4 de0)历史地震的史料记录频度看（图5），宋朝以前的绝大部分时间都在（2次/10年）以下；宋朝出现了印刷术，记录频度增到（3次/ 10年）以上；1900年后现代地震仪问世，记录频度达到（100-1000次/10年）的高水平。

As a bonus, the simple implementation is two orders of magnitude faster than the self-generating code!

另外，这种简单的实现方法比刚才那个恐怖的代码要快两个数量级！

Increase/decrease switch, which is a self-restoring switch, is used to adjust the magnitude of the generator voltage or reactive power.

增磁、减磁开关，为自复位开关，用于调节发电机电压或无功功率幅度。

So we designed a adaptive synchronizing controller based on hereinbefore hardware environment: first a small magnitude reference signal r is outputted to system through the signal card (to ensure that the vibrating system works in a linear state), and this signal is sent to the moving coil of vibrator through the power amplifier, so vibration is produced through electromagnetic induction. Secondly the vibration signal can feedback to the data acquiring card in the servo system through the acceleration sensor on the Vibroseis reactor M〓 and the base-plate M〓, then the computer can get the current vibrating state y〓 of the coil of vibrator according to the feedback information from the data acquiring card, and give a real time comparing between the current state y〓 and the reference output y〓 of the set-in reference model with current reference input being r , then regulates the correlative controlling parameters according to the error e〓=y〓-y〓 till y〓→y〓, finally normal signal sweeping begins with a certain phase fixed. Meanwhile a synchronization signal for seismic signal record is sent to seismograph from synchronization signal outputting component in the Vibroseis system to perform the controlling process of synchronization of sweeping phases.

为此，我们基于以上的硬件环境设计了一个自适应同步控制器：首先通过信号发生卡对系统输出小幅度的参考信号r(从而保证振动系统工作处于线性状态)，信号通过前置放大器、功率放大器等送到激震器动圈，并通过电磁感应产生振动，振动信号通过可控震源激震器反应块M〓和基板M〓上的加速度传感器反馈给伺服系统中的数据采集卡，工控计算机根据采集卡的反馈信息，获取当前激震器动圈的振动状态y〓，并实时地将该状态与内置的参考模型在当前参考输入r下的参考输出y〓进行辨识，再将两者输出误差e〓＝y〓-y〓对系统的有关控制参数进行调整，直至y〓→y〓，最后在经过某一固定的相位后，开始信号的正常扫描过程，与此同时，由可控震源系统的同步信号输出部件向地震仪送出一地震信号记录同步信号，进而完成扫描相位同步控制过程。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
