Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.

可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明：青南凹陷中部的下白垩统烃源岩生油门限深度为4000m（相应的镜质体反射率为0.65％），埋深4000～4400m为低成熟阶段，埋深4400～5200m为成熟生油高峰阶段，因此中沟组烃源岩未成熟，下沟组上部烃源岩低成熟，下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段，赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段，目前尚无烃源岩达过成熟干气阶段。

The main organic acid was citric acid, followed by malic acid. Citric acid and tartaric acid levels increased during storage. Malic acid and quinic acid increased from stage one to stage two. Shikimic acid level increased from stage one to stage three, then decreased slightly. Acetic acid changed unremarkably. Succinic acid changed not significantly from stage one to stage two, then increased and it was the highest in the stage three. The level in stage four and stage five was lower than the level in stage three.

五九香梨果实中的主要有机酸是苹果酸和柠檬酸，整个贮藏期间，柠檬酸和酒石酸含量处于上升趋势，苹果酸和奎宁酸含量在第一、二月贮藏期间增加，而后开始下降；莽草酸含量在贮藏期第一到第三阶段上升，而后略下降；琥珀酸含量在第一到第二阶段变化不明显，接着有上升的趋势，在第三阶段含量达到最高，第四和第五阶段略低于第三阶段；乙酸含量变化不明显。

It abandon the traditional measure that divide the development course of the scientific and technological park according to the time, and redistrict their development courses according to the logic route that the park grew up, then divide development course into three stages: embryonic stage, it introduce domestic and international agricultural new and high technology , advanced equipment directly, engaged in running an enterprise on a commercial way, use the new and high technology to carry on precise, deep processing or storing and keeping fresh to the high-quality agricultural and animal products, do not have cooperation with local peasant basically; the stage of growing up, the park brings along local peasants production, does not confine to the production of the industrial base in the park again, a kind of nonstandard cooperative form has appeared between peasant and park; at ripe stage, the park sets up the training center of agricultural science and technology, carry on the professional technical training to the industrial base and peripheral peasant, spread through three kinds of diffusion effects, such as radiation, the grade

摒弃了按时间划分科技园区发展历程的传统作法，按照园区成长的逻辑路线对其发展历程进行了重新划分，将发展历程分为三个阶段：萌芽阶段，园区内直接引进国内外农业高新技术、先进设备，从事企业化生产，运用高新技术对优质农畜产品进行精、深加工或储藏保鲜，与当地农户基本上没有合作关系；成长阶段，园区带动当地农产生产，不再局限于园区內产业基地的生产，农产与园区之间出现了一种不规范的合作形式；成熟阶段，园区建立农业科技培训中心，对产业基地及周边农产进行专业技术培训，通过辐射扩散、等级扩散、跳跃扩散三种扩散效应，把经济动力和创新成果传导给周围地区，园区进入规范化管理阶段。

The whole researching process of hypo- thetical reasoning can be divided into two stages:the first stage from1960's to 1970's——the problem putted forward,the second stage from 1980's to today——the theory developing.

假言推理研究的进程大致可分为两个阶段：第一阶段是从20世纪60年代至70年代末——问题提出阶段，第二阶段是从80年代初至现在——理论发展阶段。

The dissertation compartmentalizes four phases for evolution situation of urban human settlements construction in Xi'an. Slow-motion developmental phase before 1990, every factor steady slow developmental phase from 1991 to 1995 year, tangible establishment fast developmental phase from 1996 to 2000 year, senior quality balanced developmental phase since 2000 year.

3西安城市人居环境质量发展过程可划分为四个阶段：1990年代以前的缓慢发展阶段；1991年至1995年各影响因素稳步低速发展阶段；1996年至2000年人居环境硬件设施快速发展阶段；2000年以后人居环境高质量均衡发展阶段。

Evolution history of Jianghan Basin can be divided into Seven stages by sedimentary character since Cretaceous: uplifting and decomposing stage (lower-middle Cretaceous), whole downfaulting stage , regional subsiding stage , uplifting and decomposing stage , differential downfaulting , shinking-subsiding-uplifting and denudating , subsiding stage , differential elevating and subsiding-stabilizing stage (lower Pleistocene-early stage of middle Pleistocene), whole subsiding stage (middle stage of middle Pleistocene), shringking stage (upper Pleistocene-Holocene).

通过对江汉盆地白垩纪以来沉积特征的分析认为，江汉盆地的整体演化可以分成七个阶段，分别为：拱升张裂、整体断陷、区域坳陷、拱升张裂、分化断陷、萎缩坳陷—上升剥蚀、坳陷阶段、差异升降—稳定阶段（早更新世—中更新世早期）、整体坳陷阶段（中更新世中期—晚更新世）、萎缩阶段。

The results indicate that eye scanpaths during imagery phase reenacted those of perception; consistency between eye movements during imagery and perception influenced the correctness of imagery;restricted eye movements during imagery decreased correctness of recall.In experiment 2,eye movements were recorded in the same condition with experiment 1 but prevented rehearsal before imagery.

实验一研究了视知觉条件下表象建构的眼动特征，发现在允许自由眼动的条件下，表象阶段重复了知觉阶段的眼动扫描路径；知觉阶段与表象阶段眼动的一致性影响了表象的正确性；对表象阶段眼动的限制导致表象的正确性显著下降。

In addition, we divide platoon into two states, one is unstable state, there are major small-car departure headways and heavy-vehicles effects' functions forecasting the vehicle departure time of the state; the other is stable state, we used average departure headway and microscopic car-following headway to predict the vehicle departure time of the state.

因此，我们将车队划分成两个阶段，一为不稳定阶段，主要由小车疏解间距及大车效应两个函数，共同预测此阶段之车辆疏解时间；二则为稳定阶段，分别以平均疏解间距及微观跟车间距函数预测此阶段之车辆疏解时间。

The model has two major alternating stages, slow growth and fast growth, which we call plateaus and ravines, respectively.

这个模型中存在两个主要阶段，慢速增长阶段和快速增长阶段，我们称为高原阶段和低谷阶段。

The evolution process of landslide could be divided into 4 periods: beginning and accelerating period, quick-moving period, braking period and tamping period. The damage scope and accumulation extent are also simulated satisfactorily.

计算结果表明，根据位移和速度的变化，可把整个滑动过程分为4个阶段：即启动加速阶段、高速运动阶段、碰撞减速阶段和缓动夯实阶段；较准确的模拟了滑坡体的灾害影响范围和堆积规模；通过对滑体不同点位移和速度的分析，进一步明确了滑坡为牵引式滑坡和不同点在速度、位移和加速度上的变化规律。
