0 the number of atoms in one molecule of an element -- （一个分子中的）原子数
1 in an electronic transaction (= an operation that changes data), the fact of occurring either completely or not at all -- 原子性（一个原子事务要么完整执行，要么不执行）
Continuous scattering and non-atomicity of a face-homogeneous random walk.
Although implementations vary depending on factors such as concurrency issues, the principle of atomicity i.e. complete success or complete failure remain.
However, if a failure occurs, then due to atomicity, the amount will either be transferred completely or will not even start.
Atomicity may be achieved by using a machine instruction that is able to read, modify and write the semaphore in a single operation.
Both are done to ensure atomicity and durability of transactions.
All "distributed transactional systems" rely on some atomic commitment protocol to coordinate atomicity (whether to commit or abort) among processes in a distributed transaction.
An example of atomicity is ordering an airline ticket where two actions are required: payment, and a seat reservation.
Transaction consistency is also frequently referred to as atomicity.
