放置TCu200和TCu220宫内节育器后一年半内宫颈粘液中铜离子释放规律

用原子吸收法对使用Ｔ（Ｃｕ）２００和Ｔ（Ｃｕ）２２０型宫内节育器妇女的围排卵期宫颈粘液中铜离子浓度进行测定，以自身未带器前（Ｏ期）为对照。结果，带器者在第１，３，６，１２，１８个月宫颈粘液铜离子的平均浓度分别为；３．１８８，２．６９５，２．３２３，２．２４７，２．１１６μｇ／ｇ粘液湿重，与未带器前含铜量（０．８１８）相比，均有非常显著性差异（Ｐ＜０．０１），铜离子释放量随时间延长而逐渐减少。     

饱和光纤中的各阶孤子及孤子相互作用

首先研究了非线性饱和光纤中各阶孤子存在的幅值范围，与标准非饱和情况的非线性薛定谔孤子非常不同，即一阶孤子幅值范围是１．４≤Ｎ≤∵．０，二阶孤子为４．０≤Ｎ≤♀．０，三阶孤子为７．０≤Ｎ≤≤１５．０，并分析了各阶孤子的传输特性，最后研究了双一阶孤子相作用的若干特点，明确了五个方面的特性。     

An analysis of (h,k, 1)-Shellsort

One classical sorting algorithm, whose performance in many cases remains unanalyzed, is Shellsort. Let h be a t-component vector of positive integers. An h-Shellsort will sort any given n elements in t passes, by means of comparisons and exchanges of elements. Let S>_j(h; n) denote the average number of element exchanges in the jth pass, assuming that all the n! initial orderings are equally likely. In this paper we derive asymptotic formulas of S_j(h; n) for any fixed h = (h, k, l), making use of a new combinatorial interpretation of S₃. For the special case h = (3, 2, 1), the analysis is further sharpened to yield exact expressions.     

A simultaneous redox, alkylation, self-assembly reaction under solvothermal conditions afforded a luminescent copper(I) chain polymer constructed of Cu3I4- and EtS-4-C5H4N+Et components (Et = CH3CH2)

A simultaneous redox, alkylation, self-assembly reaction under solvothermal conditions afforded a novel copper(I) chain polymer constructed of luminescent Cu3I4- and unprecedented EtS-4-C5H4N+Et components (Et = CH3CH2).     

Finding the convex hull of a simple polygon

It is well known that the convex hull of a set of n points in the plane can be found by an algorithm having worst-case complexity O(n log n). A short linear-time algorithm for finding the convex hull when the points form the (ordered) vertices of a simple (i.e., non-self-intersecting) polygon is given.     

Phosphine-triggered complete chemo-switch: from efficient aldehyde-alkyne-amine coupling to efficient aldehyde-alkyne coupling in water

[reaction: see text] A phosphine ligand served as a remarkable chemo-switch for the silver-catalyzed reaction of alkynes with aldehydes in the presence of amines in water. Exclusive aldehyde-alkyne-amine coupling product was observed in the absence of phosphine, whereas in the presence of a phosphine ligand, exclusive aldehyde-alkyne coupling product was obtained.     

Synthesis of substituted quinolines by electrophilic cyclization of N-(2-alkynyl)anilines

Quinolines substituted in the 3-position by an iodo or phenylseleno group are readily prepared in good to excellent yields by the reaction of propargylic anilines with appropriate electrophiles under mild reaction conditions. [reaction: see text]
