It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Nd-200 (Neodymium, atomic number Z = 60, mass number A = 200). Landolt-Brnstein Homepage Introduction Index...
public static AtomicLong nextNumber = new AtomlcLong(); // 在某些线程中... long id = nextNumber.incrementAndGet(); 上例中的 incrementAndGet() 方法会自动将 AtomicLong 的值加 1,并返回增加后的值(注意:该操作是原子的,要么全部成功,要么全部失败)。该方法的功能类似如下代码: //1.获取值 long valu...
Cell[]数组:竞态条件下,累加个各个线程自己的槽Cell[i]中 /** Number of CPUS, to place bound on table size */// CPU核数,用来决定槽数组的大小staticfinalintNCPU = Runtime.getRuntime().availableProcessors();/** * Table of cells. When non-null, size is a power of 2. */// 数组槽,大...
例如,为ConcurrentHashMap<String,LongAdder> freqs进行增量计算,可以使用freqs.computeIfAbsent(k -> new LongAdder()).increment(); 这个类继承自Number类,但是并未定义equals()/hashCode()/compareTo()等方法。 因为实例对象预计是变动的,所以并不适于作为集合类型的Key。 3.内部实现浅谈 原子类型累加器其实是应...
The main thing to notice is that for thermal engines, the lower the molecular weight of the propellant, the better. When you are dividing by M, you want the number you are dividing by to be as small as possible. For combustion chamber temperatures below 5000K with hydrogen propellant, for...
Burying the habitat can be done in a number of ways, but it does pose its own problems. Heavy equipment would not be very effective in this low gravity field, if at all—mostly because it wouldn't be heavy. Get a blade full of dirt and your tracks will simply dig out from under ...

To obtain a high-resolution map for in-depth analysis of the D1–D2 domain, Bayesian polishing was performed and followed by subtraction of single-ring from double-ring particles, which effectively doubled the total number of particles to 398,906 and led to a reconstruction of 2.83 Å...
Controlling coherent light is essential to the use and understanding of atomic systems1,2,3,4. A number of features are desired in optical control: the application of frequency shifting5or frequency-domain shaping6,7; the execution of fast operations, for instance to compensate for finite atom ...
