attenuation, the time constant is T2.
T1 relaxation occurs because of the energy exchange between the rotating nucleus and the surrounding environment (that is, the lattice, the lattice), the number of nuclei that cause the up state and the down state to change, and the number distribution to revert back to the non-B1 equilibrium, so MZ reverts to M0, and T1 is also called spin-lattice relaxation time.

instance.Launch the EC2 instance3. Now, when you're using a "free tier" account, then it's a good idea to select the "No Tier" radio button so that AWS can filter out instances that can be used freely. This allows you to not pay for resources that use AWS.Select Free Tier instances only4. To continue, please select the following options:A, select an AMI (Amazon machine Image) in the Classic Instance wizard, then choose to use Red Hat Enterprise Linux

I. Overviewthis chapter records in the implementation process, creating steps for an AWS EC2 instance. Ii. descriptionAmazon Elastic Compute Cloud (Amazon EC2) provides scalable compute capacity in the Amazon Web Services (AWS) cloud. With Amazon EC2 , you can avoid upfront hardware investment, so you can quickly develop and deploy applications. By using Amazon EC2, you can start as many virtual servers as
Designing highly available applications is an important goal of architects. However, Designing highly available applications based on cloud computing platforms is different from designing traditional platforms. When cloud computing brings many new design challenges to architects, it also brings many new design concepts and available services. How to make full use of the features of the cloud platform when designing applications is an important condition for cloud computing-based design. In this
offers more than 700 free and premium software products that can be run in the AWS free tier. If you qualify for the AWS free tier, you can use these products for up to 750 hours per month in an Amazon EC2 T2.micro instance without paying an additional fee (up to 12 months) for Amazon EC2 instances. Charges for the fee software are still applicable.

Learn how to create AWS LAMBDA functions This execute on a scheduled interval and much like a cron job would. In this lesson we'll create a LAMBDA function that checks for a string of text on a website to verify the website are up and operational. The lambda function logs to CloudWatch Metrics and sends a notification e-mail using an SNS queue if the check fails.Create a lambda function: (WebTest)Exports.handler =function(event, context) {varHTTP = re
