These applied loads meet the real-life situation, where there is a large-scale fluctuation in load observed in gearboxes.

这些应用载荷满足现实生活的情况，那里是一项规模宏大的波动负荷，观察在变速箱。

But this also with the voltage grid voltage fluctuations (generally plus or minus 10% fluctuation) load and temperature change.

但这样的电压还随电网电压波动（一般在正负10％左右的波动），负载和温度的变化而变化。

The reactive power variation of wind farm interconnected with power grid leads to voltage fluctuation of power grid.

并网风电场无功功率的波动会引起系统电压波动。

Since the initial start of buried pipelines results in three-dimen-sional unstable heat transmission , and at initial start the temperature change of the soil around a pipeline is affected by the temperature inside the pipeline and the ground surface temperature annual fluctuation, the differential equation for heat transmission and the boundary value may be line...

埋地输油管道启输过程是三维非稳定传热问题，启输过程中管周土壤温度场的变化受管内热水温度和启输前地表面温度年波幅的影响，可将传热微分方程和边值条件线性组合成两个定解问题，用电子计算机进行数值求解，得出计算公式，以确定预热阶段管路任一点任一时刻的热水介质温度。

Retrogressive erosion data of long-term monitoring in the typical thaw slumping indicates that expanding of the thaw slumping fluctuates along with the ground temperature's annual fluctuation, and expanding mostly takes place in 7~9 months. The maximal expanding appears at the direction of the slope tendency.

滑坡溯源侵蚀范围监测资料表明，滑塌范围的扩展随地温的周期变化波动进行，并主要集中在7~9月，最大扩展范围出现在沿坡体倾向方向。

Among the slope instability types, thaw slumping is the most hazardous to engineering projects. The ground temperature data of long-term monitoring in the typical thaw slumping indicates that average ground temperature increases and annual fluctuation of ground temperature are reducing under the thaw slumping. The reason is that the heat flux entering permafrost reduces.

针对典型热融滑塌进行的温度监测资料表明，在滑塌的影响下，其下多年冻土地温年变化幅度趋小而年平均地温升高，导致产生这一现象的原因在于每年进入多年冻土的冷能有所降低。

Furthermore, an integrative anti- interference solutions are provided, which are consisted of both hardware ones and software ones. Solutions in hardware include a multi-layer shielding structure and proper groundings of the whole system. Solutions in software include digital data pretreatment based on wavelet, FIR digital filter and algorithm of improved high order sine fit method. They do resolve the corresponding problems in on-site monitoring caused by strong electromagnetic field, noise in signals and harmonic and the fluctuation of power system frequency.
