Results: In all 13 patients, non-contact mapping showed AFLs confined to the RA with the cycle length (230 ±20 ms). 6 patients presented single-loop re-entry circulating around the central obstacle in the anterolateral wall through the channel between the CO and the crista terminalis .Seven patients presented "8" re-entry, and the gap of upper and lower loop located in CT in 4 cases, another 3 cases with upper loop and free-wall single-loop re-entry. RF of CT gap and/or the free-wall channel was effective in eliminating these AFLs in 13 patients.

结果 经 NMS标测证实13例患者折返均在右房内，激动在右房内的折返平均时间为230±20ms.6例房扑患者为单折返环，围绕右房中心障碍区折返，激动在心房的前壁穿过中心障碍区与界瘠之间的狭窄通道。7例患者证实为2个折返环，其中4例表现为上下折返环形成"8"字形折返，共同的传导通道在界瘠；另外3例表现为折返环1个在心房上部，1个在前游离壁。13例消融界瘠或前游离壁后房扑终止。

Location-inventory system integrated design problem under stochastic demand The location-inventory distribution system design problem involving one supplier, candidate distribution centers and multiple retailers under normal distribution demand is studied in the background of building materials industry. Retailers adopt periodic reviewinventory policy, while distribution centers adopt continuous reviewinventory policy. Considering the trade-off between inventory cost, shipping cost and facility location cost, the integrated 2-echelon inventory control policies with incapacitated facility location model is presented.

随机客户需求下的选址-库存集成问题研究：以满足正态分布客户需求的型材配送物流为研究背景，研究了由单供应商、候选分拨中心和分销点构成的配送物流系统集成规划问题，分销点、分拨中心分别采用周期检查和连续检查库存控制策略，综合考虑库存成本、运输成本和设施成本之间的均衡关系，建立了二级库存控制策略与无能力约束选址集成规划模型。

The patients were divided into four groups. Group A included 48 women with previous unilateral salpingectomy. Group B included 41 patients with previous bilateral salpingectomy. Group C included 50 patients with obstruction of fallopian tube while group D included 40 patients with hydrosalpinx (without surgical procedure before). The ovarian responses to superovulation and the outcomes of IVF-ET were evaluated.
