递减

Every strictly decreasing sequence of elements of the set must terminate after only finitely many steps (assuming the axiom of dependent choice).

注意这个第三点：对于一个良序集，任何严格递减序列都必然是有限的，无论这个集合的基数有多大。

结果表明，过氧化物最佳注入口应选择在靠近口模处，加入方式可选择侧位重量加料器或高压计量泵系统，后者可通过压力表、过氧化物的递减量对生产过程进行控制。

About the windbreaks of Chi-Sing Tang, the average wind and salt reduction already reached 90% at 140 m inside it; furthermore, the salt content of beefwood, in the soil and the amount of floating all increase with the horizontal distance but decrease progressively and descend 10 mg/100ml at 150 m; however, the average temperature and ground temperature is 2℃ higher, and the water content in soil is about 0.4% higher inside the forest belt than the outside of it; the trend of the atmospheric pressure and opposite moisture is the same, but the illumination is only 1/215, and the radiation is 1/20 of that of the outside forest belt.

至於七星潭海岸防风林经分析得知，位於防风林带内140 m处减风与减盐效果可高达约90%；再者，叶片与土壤盐份量及空中飘盐量之分布，随水平距离增加而递减，在150 m处皆已降至10 mg/100ml以下；至於林带内平均气温与地温则较林带外高约2℃，土壤含水量较林带外高约0.4%，而气压及相对湿度亦有相同之趋势，但光照度则仅为林带外1/215，日辐射量亦只有1/20。

During the PL measurement excited by 405nm diode laser, the decreasing PL intensities of the biased LED sample were observed by increasing the measurement temperature that was caused by the thermal and tunneling effect to have the lower internal quantum efficiency.

在光激发萤光系统上，以405nm波长的雷射作为激发光源，在外加偏压测试环境下可以发现室温(300K)强度因载子热效应与穿隧效应而快速递减，导致内部量子效率较实际值低。

Bluefin, bigeye and yellowfin tuna has been overfished for many years, with pirate fishing being a serious problem. The fishing industry is already suffering as the catch of bluefin tuna has dropped significantly over the last few years and average weight of the catch also dropped.

由於非法捕鱼问题严重，加上黑鲔、大目鲔与黄鳍鲔等多年来被过度捕捞，以至鲔鱼以惊人的速度不断减少；以台湾捕抓的黑鲔为例，不仅鱼体重量减轻，鱼获数量更是逐年递减。
