[0052] In specific implementation, the nanobeam gradient response test is started, and the nanobeam strain data set of the target nanobeam is obtained through the nanobeam database. It should be noted that the nanobeam strain data set in the present application is a collection of all nanobeam strains, wherein the nanobeam strain in the nanobeam strain data set is the strain of the target nanobeam caused by the stress applied to the target nanobeam at different test temperatures, and the test temperature ranges from -50°C to 50°C. The test is started from -50°C, and each change of 5°C corresponds to a test temperature, and one test temperature corresponds to one strain.

[0053] In addition, it should be noted that the external factors in the present application may be, for example, temperature, humidity, wind speed, dust, etc. In this solution, the influence of the external factor of temperature on the target nanobeam is analyzed.

The nanobeam stress correction coefficient is set according to all the nanobeam stresses in the historical nanobeam stress data through the linear regression method of the prior art. The value range of the nanobeam stress correction coefficient is 0-1. In other embodiments, other methods can be used for setting, which is not limited here.

[0081] It should be noted that the cohesive loss in the present application is a parameter value that reflects the central trend of the damping degree of the target nanobeam under stress, and is used to predict the damping effect of the target nanobeam.

[0082] In step 103 , the nanobeam curvature of each nanobeam strain in the nanobeam strain dataset is determined according to the nanobeam strain dataset and the real-time surface load.

[0086] Then, in step 1033, all nanobeam topological quantities are converted into nanobeam topological sequences;

[0087] Finally, in step 1034, the nanobeam curvature of each nanobeam topological quantity in the nanobeam topological sequence is determined.

The larger the nanobeam topological quantity, the smaller the stress rebound of the target nanobeam at the corresponding test temperature; all nanobeam topological quantities are converted The invention relates to a nanobeam topological sequence, that is, all nanobeam topological quantities are arranged in ascending order according to the corresponding test temperature, and the sequence obtained by the arrangement is used as the nanobeam topological sequence; the nanobeam curvature of each nanobeam topological quantity in the nanobeam topological sequence is determined, that is, the first nanobeam topological quantity is subtracted from the second nanobeam topological quantity in the nanobeam topological sequence, and the value obtained by the subtraction is used as the nanobeam curvature of the second nanobeam topological quantity, the second nanobeam topological quantity is subtracted from the third nanobeam topological quantity in the nanobeam topological sequence, and the value obtained by the subtraction is used as the nanobeam curvature of the third nanobeam topological quantity, and so on, until the second-to-last nanobeam topological quantity is subtracted from the last nanobeam topological quantity in the nanobeam topological sequence, and the value obtained by the subtraction is used as the nanobeam curvature of the last nanobeam topological quantity. It should be noted that in the present application, the nanobeam curvature of the second nanobeam topological quantity is used as the nanobeam curvature of the first nanobeam topological quantity.

[0089] It should be noted that in the present application, one nanobeam topological quantity corresponds to one test temperature; the nanobeam curvature is a parameter value that reflects the degree of elastic change of the target nanobeam between adjacent test temperatures. The greater the nanobeam curvature, the greater the elastic change of the target nanobeam between adjacent test temperatures. The nanobeam curvature is used to predict the strain of the target nanobeam.

[0090] In step 104, the extension decision factor corresponding to the curvature of each nanobeam is determined by the cohesive loss, and multiple stress response feature prediction bases of the target nanobeam are determined according to all the extension decision factors and the nanobeam strain data set.

The value range of the time correction coefficient is 0-2. The time correction coefficient is set for all historical test times in the historical test time data through the linear regression method of the prior art.

[0112] In specific implementation, a surface load can be applied to the target nanobeam at a specified test temperature, and the real-time surface load is divided by the stress response characteristic prediction base corresponding to the specified test temperature. The value obtained by the division is used as the nanobeam strain of the target nanobeam at the specified test temperature for the surface load. The above steps are repeated to determine the nanobeam strain of the target nanobeam at different test temperatures and different surface loads. All the obtained nanobeam strains are used as the stress gradient values ​​of the target nanobeam. In some embodiments, all stress gradient values ​​can be used to generate a stress gradient table through the existing python software, and the stress gradient response of the target nanobeam is predicted through the stress gradient table, which will not be repeated here.
