As discussed in Chapter 1, the radioactivity of heavy atoms, embodied in the three processes of α-, β- and γ-decay, were early indicators of nuclear activity. With the production of many species of nuclei in their ground or excited states through nuclear reactions such decays have been ...
Alpha, beta and gamma radiation are the original and still-standing names for the three major types of radioactive decay of atomic nuclei. These are the first three letters in the Greek alphabet and represent increasing levels of biological danger upon e

Does beta decay release energy? What are alpha, beta and gamma decay? Is energy absorbed during beta decay? What is emitted from the nucleus during beta decay? What is the equation for beta minus decay? Why is energy lost in beta decay?
A pre-release of software that is given out to a large group of users to try under real conditions. Beta versions have gone through alpha testing in-house and are generally fairly close in look, feel and function to the final product; however, design changes often occur as a result. ...

Jost(2007)认为目前的beta多样性定义使得其数值依赖alpha样性, 因此难以进行区域间beta多样性比较。他提出将多样性分解为相互独立的alpha和beta多样性组分, 并发展了具体的度量方法, 认为对gamma多样性的倍性分解才是真正的beta多样性, 才适用于区域间beta多样性比较。基于这一分解方法和有效物种数概念(effective ...
