If you divide the 20th century into quartiles, the period when the initial yield gap was highest (ie, bonds yielded more than cash) saw a subsequent ten-year real return from gilts of just 0.3%.
Calculation case shows that in the given initial value and restraints, convexity gap model can lessen the exposure position of interest rate risk and increase yields.
计算实例表明，凸度缺口模型对于给定的初始值和约束条件，可以较好地减少利率风险的暴露头寸和提高收益；

Material to be bonded after the initial setting, with bamboo and other materials scrape off excess adhesive, then brush the surface of the gap repair.
