Amur tigers had a copulatory pattem with no lock,thrusting, multiple intromission,and single ejaculation,which belonged to copulatory pattern No.11 in Dewsbury\'s copulatory-patterned system.5 The behaviors that accounted for most of the total time budget during the parturition period were grooming,lying and licking kittens,26.90%,26.23%and 23.83%,respectively.

东北虎的交配模式属于Dewsbury分类系统中的第11种，即无锁结、有抽动、单次插入、多次射精。5在分娩过程中，雌虎的梳理、卧息和舔仔行为时间最长，分别为26.90%、26.23%和23.83%；梳理、努责和舔仔行为发生频率较高，分别是37.95%、18.75%和12.50%。6在育幼过程中，雌虎室外期与室内期哺乳和亲仔行为的时间差异极显著(P＜0.01)，离开行为的时间差异显著(P＜0.05)。

Some electrophysiological index were measured, including atrial effective refractory period, rate adaptability, dispersion of AERP, inducibility and duration of induced atrial fibrillation under different basic pacing cycle length (300, 250 and 200 ms). Results: Contrast with control group, the values of AERP at 6 sites were shortened and maladaptation.

将6对双极记录电极分别缝于高位左、右和低位左、右心房外膜以及左、右心耳，采用心脏程序期前刺激法(S1S2)，分别测量基础起搏周长为300、250和200ms时的心房有效不应期、AERP频率适应性、AERP离散度、房颤诱发率及平均持续时间等电生理指标。

Objective To investigate the relationship between the first polar body morphology of oocyte and the zygote morphology in pronucleus stage, embryo quality in cleavage stage.

Identification and forecasting for igneous rock is one hard problem of exploration activity, because it has extreme aeolotropism. By firstly synthetically utilizing seismic analysis, well logging restricted inversion, core well core and electric log analysis method and so on, the igneous rock reservoir of Gaoqing oilfield is effectively identified and divided into one to four four phases according to igneous rock erupting phase.

由于火成岩具有极强的非均质性，对其识别与预测是油气勘探的难题之一，首次综合使用地震分析、测井约束反演、取心井岩心与电测曲线分析等技术和方法，有效地识别了高青油田火成岩储集体，并根据火成岩喷发期次，将高青油田孔店组火成岩储集体分为1、2、3、4期。

Result There was no significant difference to the number and length of parenchyma cell in the uppermost internode between Shuangdi Pei eS and Shuangdi S in meiosis and dikaryon pollen stages;there was significant difference to those in tikaryon pollen stage, and there was very significant difference to those in anthesis and the 7th day after anthesis,and on the 7th day after anthesis,the difference to the number and length of parenchyma cell in the uppermost internode between Shuangdi Pei eS and Shuangdi S was the greatest.

长穗颈双低培eS与双低S穗颈节间薄壁细胞数及细胞平均长度在减数分裂期和二核花粉期差异不明显，于三核花粉期差异达显著水平，始花当天和始花后第7天均达极显著水平，其中始花后第7天时两者的差异最大。

The forming of non- Smithian strata are expounded at theory level.

以殷鸿福等（1998）归纳总结的非威尔逊旋回理论为指导，从理论上阐述了非史密斯地层形成过程：造山带区古大洋相当复杂，尤其是中国古特提斯域古大洋，多为多岛洋，多岛洋是一个宽阔的但不干净的洋，它在其各个演化阶段，始终充满着由裂解地块、裂谷、海道、微板块与次级小洋盆、火山岛弧、海山与边缘海等不同裂离与聚合程度的、海陆相间的多岛洋盆；多岛洋盆在其整个洋陆转化进程中，往往所经历的是多期开合与多期次软碰撞，故由非威尔逊旋回转化而来的造山带混杂岩带地层一般都经历过多期强烈的构造混杂，使造山带演化不同期次、同期次不同阶段、不同大地构造相、不同沉积古地理单元、不同构造层次地层体在极短程内相互拼贴、无序叠置。
