积分判别法
1.
The convergence theorem for a type of series is given, from which a number of conclusions are obtained such as (1) convergence and divergence of a series with integral test; (2) a group of convergent series; (3) series ∑∞n=1f(a_n) and sequence {∫~(a_n)_(a_1)f(t)dt} are of the same constringency; and (4) estimation of the sum of some constringent series and the value of some improper integrals.
给出了判定一类数列收敛的定理,并由此定理得到一系列结论:(1)级数敛散性的积分判别法;(2)一类收敛数列;(3)级数∑∞f(an)与数列{∫anf(t)dt}同敛散;(4)估计某些收敛级数和值与广a1n=1义积分之值。

收敛药(收敛剂)
能沉淀组织内部分蛋白质而促使组织皱缩的药物,有消炎退肿的作用,用于治疗皮肤粘膜炎症。主要有两类:(一)鞣酸和鞣酸蛋白。前者局部应用可治疗皮肤粘膜炎症,后者可供口服,有止泻作用。(二)金属类。如硝酸银、硫酸锌等,兼具不同程度的抗菌作用,供外用。
