Composite gear not only has a series of advantages such as smooth transmission, noise and vibration reduction, corrosion resistant, wear resistant and self-lubrication, but also has characteristics just like metal gears such as high carrying capacity and transmission power[1].

One of the resonator structures, the vertically coupled whispering gallery mode (WGM) resonator optical waveguide was proposed and modified as a method of reducing the group velocity of light for optical buffering and it can be used to route and switch optical data signals [6].

The coefficient initially increased with clay content reaching a peak at about 1wt%, followed by a gradual reduction with further increasing clay content.
Interestingly, the variation of data became larger with increasing clay content, a reflection of the removal of clay aggregates during the scratch test.

The test data were recorded until the sample breakage, then circulating hysteresis loop and low cycle fatigue life curve was drawn.
The strain amplitude changed from 0.05mm to 0.25mm leaded to the reduction of the low cycle fatigue.

The intensity of two major peaks for the (211) and (002) planes of HA-FB100 was lower than HA-FB50, indicating the reduction of the crystal growing energy with an increase of fibroin content.
From TGA data of HA-FB100, we can observe large loss in sample mass around of 287.5℃ and 416.7℃.

Each data point was the average of five to seven samples.
The samples prepared with 1 phr of Fe3O4 show the best TS and EB, while further addition of more Fe3O4 would cause a reduction in both properties.

Introduction The need for weight reduction in automotive components motivates the development of high temperature structural magnesium alloys with low cost.
Figure 2 illustrates some of the creep data collected.

Hydrogen evolved immediately, and the solution changed from pale pink to brown/ gray indicating the reduction of Co (II) into cobalt nanoparticles.
According to the data of product selectivity, it can be concluded that cobalt-based FT catalysts have higher selectivity and activity.

As expected on the basis of literature data, BCY decomposed in BaCO3 and CeO2, while BZY maintained a pure perovskite phase.
The reduction in conductivity was accompanied by an increase of Ea from 0.43 eV for the bilayer to 0.61 eV for BZY.

The current problems, if increase FFT length will need to add data storage, meanwhile, FFT transformation calculation logarithm growth, cannot achieve spectrum analysis of real-time, On the other hand, reduce the sampling rate, will affect AD the authenticity of sampling signal, which will severely affect shift frequency automatic block system reliability, and may even cause serious traffic accident.
It can’t avoid that the window effect in time domain lead to the peak of spectrum line and resolution of spectrum reduction, because that we can only process the finite signal samples.
