Human factors in computing systems , 1993 , pp . 488 - 493 . 11 meehan m , razzaque s , whitton m c , brooks f p . effect oflatency on presence in stressful virtual environments 100 ms 600 ms之间值的选择最好不要超过分界点300 ms ，否则微小的差异会造成很大的性能破坏。
For the evolution stars with age less than 109 years , stellar magnetic activity and rotational period decrease with stellar age ; for the stars with age larger 而晚型演化恒星不论是演化恒星的磁活动还是自转周期以恒星年龄10 ”年为分界点表现出随年龄不同的规律。
Whether female disposition is described objectively and their valuation is presented or not is the distinction between simulation and objectivity in female poetry of tang dynasty 摘要能否真实书写女性的性情，展示属于自己的价值判断，是区分唐代女性诗歌模拟与真实的分界点。
These two phases are separated at a time when the halo concentration parameter c ~ 5 and the binding energy of the halo is approximately equal to that of a singular isothermal sphere with the same circular velocity 肠‘随时间的增长和宇宙的膨胀速率基本一致: ( 2 )在这两个阶段的分界点处暗晕的汇聚因子。
In the process of analyzing return factor , for the fist time the quantitative approach is used to analyze the four stages of high - technical products " life cycle , and the four periods are demarcated . 3 在收益因子分析中，首次提出了高技术产品寿命周期四个阶段的定量分析，并确定出四个周期的分界点，为准确计算高技术价值量提供了依据。
When the method of incremental variable stiffness is used in the plastic analysis , the loads are applied sequentially . once the plastic hinge is formed , the loads are increased . so the whole process is divided into many stages 在塑性分析中主要采用增量变刚度法,荷载是逐级施加的,以每形成一个塑性铰为分界点,把整个加载过程分成若干个阶段
The whole process is divided into two stages by the boundary of the opening up and reform . making a gender analysis , we can conclude that gender difference is running through the two stages and standing out as the advance of the de - agriculturization 从建国后到现在的发展历程中，以改革开放为分界点，分为两个阶段，对两个阶段的非农转移进行性别分析，可以得知性别差异贯穿在两个阶段之中，并随着非农化的大规模发展而更加突出。
The life cycle of financial innovative products consists of input , growing , maturing , and declining stages . three dividing points of the four stages can be calculated quantifiably by compertz curve . in input stage capital should be invested to promote the products , and occupy the market 金融创新产品的生命周期包括投入期、成长期、成熟期和衰退期四个阶段，通过龚珀殊( compertz )曲线可以从定量的角度分别计算出四个阶段的三个分界点。
Make using of the critical point of the arch failure transiting to the tooth failure ( which is also the point when the non - stirrup beam ' s shear bearing capacity arrives to its minimum ) which is advanced in the arch - tooth theory of beams without shear reinforcement by g . kani and the critical point of the diagonal - tension failure transiting to the shear - compression failure which is advanced in the anti - theory , the minimum shear resistance of general bea ms which is destroyed in the range of shear - compression failure is advanced 利用g . kani提出的拱?齿理论中的无腹筋梁的拱齿破坏的分界点(也就是无腹筋粱的最小抗剪承载力点) ，再结合前述理论中所提出的梁剪压破坏和斜拉破坏的分界点，提出了梁在延性的剪压破坏范围内的最小抗剪承载力，并与混凝土结构设计规范gb50010 - 2002比较，结果吻合较好。
The obtained results indicate that compared with the clay layer , the liquefied sand layer takes a decreasing effects on the short period component of the surface ground motion and the effects increase with increasing of the thickness 、 depth and width of the liquefied sand layer ; the liquefied sand layer takes a increasing effects on the long period component of the surface ground motion but the effect is not obviously ; to the input earthquake wave , the demarcation point of strengthens and weaken is about 0 . 6s 主要结论为:和同样的粘土层相比,液化层的存在对地表上地震动的短周期分量主要起减弱作用,且减震效果随着液化层埋深、厚度的增加而变强;对长周期分量主要起加强作用,但是效果不太明显;对所输入的地震波来说加强减弱的分界点所对应周期为0 . 6s左右。
