增益(Gain) 天线增益(Gain)是一个实际参量,该参量因天线或天线罩的欧姆损耗而小于方向性系数(Directivity)。在发射状况下,天线增益还包括向天线馈送功率的损耗,这种损耗并不意味着辐射,而是意味着加热天线结构,增益(Gain)与方向性系数(Directivity)之比是天线的效率\eta 。 Gain=\eta D \\ 通过减小振子的截面积...
Realized Gain计算公式 引言: 在投资领域中,我们经常会听到一些术语,如实现收益(realized gain)。实现收益是指投资者在卖出投资资产时所获得的盈利。计算实现收益的公式可以帮助我们准确地评估投资的盈利情况。本文将介绍实现收益的计算公式,并通过实例来展示其应用。 一、什么是实现收益? 实现收益是指投资者在卖出投资...

Realized gain. When you sell an investment for more than you paid, you have a realized gain. For example, if you buy a stock for $20 a share and sell it for $35 a share, you have a realized gain of $15 a share. In contrast, if the price of the stock increases, and you don...

realized gain (redirected fromRealized Gains) The amount by which thesale priceof anassetexceeds itspurchase price. Unless the realized gain came from atax-exemptortax-deferredasset, it istaxable. However, the type of taxation to which it is subject varies according to how long the asset has ...
A realized gain is when an investment is sold for a higher price than it was purchased. Realized gains are often subject to capital gains tax. Depending on the holding period, it will be considered either a short-term or long-term gain. ...
