Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.

构造沉降是控制层序几何形态，充填叠置方式、演化及沉积体系分布的最重要因素：凹陷由多个半地堑在不同层序发育时期以不同方式叠置联结而成；受断层控制，层序外部形态有箱状-楔形、楔形-席状披覆型，边界终止方式有双断终止型、单断终止超覆型；不同构造演化阶段层序内部充填的沉积体系各具特征，初始断陷阶段的SQ1沉积冲积层序，强烈断陷阶段的SQ2-SQ4充填湖相层序，晚期断陷阶段SQ5-SQ7内部充填浅湖和河流三角洲沉积；同沉积断层陡坡带沉降迅速、可容纳空间快速增长，是凹陷的沉积和沉降中心，断陷期主控断裂活动时间和空间的变化导致了凹陷沉积和沉降中心的迁移。

Vivipara under different weather conditions all showed two peaks, there still existed differences in the beginning and standing time of their activities, the appearing and standing time of the activities peaks, and the values of the peaks. In fine days, the beginning time of the activities was earlier, and the duration and interval time were longer; while in cloudy days, the duration for activities was shorter, and the appearance frequency of activities peaks was higher. The males devoted more time to activities and appeared more at activities peaks than the females, while the juveniles began activities later and appeared lesser than the adults.

不同性别、年龄和天气条件下胎生蜥蜴的日活动节律均为双峰型，但各种活动开始和持续的时间、活动高峰出现和持续时间以及峰值方面存在差异，晴天时胎生蜥蜴开始活动的时间早，2次活动高峰的持续时间及间隔时间长，而阴天时胎生蜥蜴的活动时间短且集中，在活动高峰时的个体出现率高；雄性比雌性的活动时间长，出现率高，幼体开始活动的时间比成体晚，出现率低。

He quoted Schultz's study in which he examined 400 primate skeletons without finding any cases of spondylolisthesis, as evidence that bipedal posture is a factor that contributes to this condition.3 The idea that repetitive stress increases an individual's risk of isthmic spondylolisthesis is also supported by studies that show an increased risk of pars defects in athletes who participate in sports involving hyperextension, such as gymnastics,4 diving, wrestling, and weight-lifting.5

他引用了Schultz的研究，他检查了400个灵长类的骨骼，没有一例脊椎前移，这个发现成了双足站立姿势是导致这种疾病的因素的证据。3运动员，尤其是从事需要过伸腰部的运动，如体操4、跳水、摔跤和举重5的运动员发生峡部不连的风险增加，这也支持了反复应力增加了发生峡性脊椎前移风险的观点。
