Today, we add the previous control task to the historical state. This task will be complicated. For such tasks, we tend to automatically generate PLC programs and write them by ourselves, which is prone to errors. But for demonstration, we can try it.

Article 4. Bootstrap grid system offset column and nested column, Article 4. bootstrap
Offset column:
In the bootstrap grid system, we can use the offset column to shift the right of a column, as shown below:
Class = "col-sm-2 col-sm-offset-1" indicates that the column occupies two portions and moves one portion to the right. The effect is as follows:
The Col-sm-offset-1 represents a right shift. The
expectedlinear correlation between effective doses and DAP is confirmed with an R2 of 0.974. Moreover, in order to easily calculate patient doses, conversion coefficients, relate equivalent doses to measurable q Uantities, such as DAP, were obtained.Through this article, we can know Dicom's all-famous medical digital imaging and communication. This paper mainly makes some calculations and experiments, and makes linear fitting. The calculation of conversion coefficients is also carried out. The
junit3 and the JUNIT4 the use of the difference is as follows1. the TestCase class needs to be inherited in JUnit3, but no inheritance is required in JUNIT4 testcase2. in JUnit3, you need to overwrite the setup and Teardown methods in the TestCase, where the Setup method is called to complete initialization before the test executes, and the Teardown method is invoked when the test results are closed. Used to release the resources in the test use, and in JUNIT4, you only need to add @before befor
