The vapor of the agent then affects the lightpath of the bonding elements.
The silica filler is usually adding to the epoxy, one of the thermosetting adhesions, for the lower properties of the curing shrinkage and the CTE [16].
Besides, the FBGs is a reliable and accurate sensor for measuring of the strain and temperature subjected to the central wavelength of FBGs with the positive linear proportional to the previous two factors.
This evidence enhances that the bonding adhesion has the curing shrinkage affecting the misalignment of the light path of optical elements.
By the optical fiber properties and the decreased stress in Fig. 6, the curing shrinkage of the filler/epoxy adhesion is about 0.05% at 60 oC.

Abstract.
But on the other hand, the disadvantages are obvious: (1) the pulse signal has a bad impact to the circuit, which can affect the accuracy of the sensor; (2) single type of excitation limits the change of the impedance; (3) frequency of the excitation signal is single, which is not conducive to fully enhance the sensitivity of GMI sensors in different environment and eliminate the possible multivalent.
However, when the magnetic field outside is zero, the curve is mixed with the non-zero curve, which would adversely affects the measurement results.
Reference [6] notes that using what kind of incentive depends on the magnetic properties of the material itself.
These factors are very useful to generate GMI effect.

Its mechanical properties have obvious thixotropy and liquidity.
It seriously affect construction environment in the connection bridge area and even affect the shield tail and the whole car.
Many harmful factors are caused by screw machine spewing, but now quite limited measures can be taken to solve this problem.

For mass imbalance, bearing manufacturing defects, electrical motor noises, and other factors, the CMG produces periodic and broadband disturbance vibration to the spacecraft while controlling torque.
The large CMG also significantly affects the pointing precision of the optical path and the stability of the remote sensing satellite.
Measuring the natural frequency of large CMG The natural frequency of rotating mechanical systems can be measured in two ways: hammering and forced oscillation.
By contrast, forced oscillation gradually increases the rotation speed of the mechanical system to measure vibration amplitude and determines the rotation speed of system resonance to calculate the natural frequency.
This effect cannot be countered by increasing the rigidity of the testing table because the intrinsic property of the table significantly affects the intrinsic property of the CMG.

According to this resistance strain effect, if a metal conductor is subjected to an external loading, its mechanical deformation will occur and lead to the corresponding change of its resistance.
It is notable that ρ is affected by lattice deformation of the conductor and other factors.
The initial posture and motion posture of experimental animals affected markedly the severity of neck injury during rear-end collisions.
The measurement circuit of this strain gauge had a linearity of 99.006% and a ripple voltage of less than 30 mV, representing its stable electrical properties.

There are so many factors affecting qualities of deep-drawing parts, such as blank holder force (BHF), the forming force and speed of punch die, die structure, lubricant, material performance, and so on.
The procedure of the optimal BHF determined by NN Comparing this set of control systems to the closed-loop control systems shows that neural network control system can reduce the spring back angle better than that as the material properties changes and it is also more stability and stronger than the closed-loop control system as the training data is enough [20-21].

While the extrusion process is significantly affected by the nozzle, the thermal conduction and thermal deformation of a nozzle can impact the properties and quality of the 3D printed parts [7].
Ding et al. [9] investigated the relationship between nozzle temperature and mechanical properties of 3D printed parts.
On the other hand, although the steel nozzle shows excellent mechanical properties at the temperature around 400℃, the high-temperature extrusion of steel nozzle is limited by the poor thermal conductivity of about 15 W/(m⋅K).
