Through the analysis of De, an alternative mechanism interpreting of the"overshoot"phenomena can be obtained: when the diffusing time of small molecular penetrants is shorter than relaxation time of the involved polymer, small molecular substance penetrates into the polymer quickly and its concentration reached a maximum, then the swelling of the polymer by the small molecules makes the chain structure of the polymer relaxed, thus the free volume in polymer matrix, which is occupied by small molecule, decreased, and will squeeze part of the small molecular substance out of the polymer, and therefore overshoot behavior can be observed.
通过对De的分析,可以得出产生&超调&现象的机理的另一种解释:小分子渗透物质的扩散时间相对于聚合物的松弛时间要短(相当于有个更快的扩散速度),所以小分子迅速扩散进聚合物中达到一个极值,由于小分子物质对聚合物的溶胀,使得聚合物链结构产生松弛,由于聚合物链结构的变化,小分子物质占有的自由体积会减小,这样会挤出小分子物质,使得小分子物质在聚合物中的浓度减小,如果高聚物粘弹性明显,甚至可能出现多个浓度的衰减振荡并达到平衡值。

Bellows Gate Valves However, in large differential pressure operating conditions, evaporation pressure has eased, the evaporator load requirements of the fluid volume decreased, but the actual situation the contrary, in the suction superheat unchanged, due to evaporation pressure has eased, the evaporator outlet pressure be reduced accordingly, pressure changes above and below the diaphragm, causing the main valve opening increases for increased fluid; but in a small pressure operating conditions, evaporation pressure rise, evaporator load demand for fluid volume increased, but the reality is that in the suction gas superheat unchanged, due to evaporation pressure rise, a corresponding increase in the evaporator outlet pressure, pressure difference above and below the diaphragm smaller, so that the main valve opening decreased for the reduction of liquid volume; in variable load is all about.
但在大压差工况下,蒸发压力降低,蒸发器负荷需求的液量减少,但实际情况相反,在吸气过热度不变的情况下,由于蒸发压力降低,蒸发器出口压力相应降低,膜片上下的压差变大,使主阀开度增大,供液量增加;但在小压差工况下,蒸发压力上升,蒸发器负荷需求的液量增多,但实际情况是在吸气过热度不变的情况下,由于蒸发压力上升,蒸发器出口压力相应提高,膜片上下的压差变小,使主阀开度减小,供液量减少;在变负荷下亦如此。

It also becomes more difficult to model and simulate power grid. Traditional"Quasi-stationary"phase models can't be used for studying electromagnetic transient phenomena; on the other hand, the EMTP models can be used to analyze the electromagnetic transient accurately, but for the limitation of the step size, it can't be used to simulate the large network with a high speed.
这对电力系统的建模和仿真提出了更高的要求,传统的机电暂态模型由于建立在&准稳态&假设基础之上,因此不能用来仿真变化迅速的电磁暂态过程;而电磁暂态模型,虽然能准确反映电磁暂态过程,但由于仿真步长很小,仿真速度受到限制,不适合用来仿真大型电力系统。

What I am concerned with is the fact that the disuse of the land deeds enabled Mao Tongqiang to re-present them before the public as the readymade Land Deeds; through the artistic activity of appreciating Land Deeds, we get to see the social upheavals linked to land's being lost, regained and lost again, as well as the harm brought by such upheavals to the whole spectrum of society's smallest constituent components—from the families of Chinese Communist Party leaders to those of every ordinary peasant.
我所关心的是,由于地契的废弃,毛同强才得以把它做成现成物《地契》,并展示在公众面前,我们通过欣赏《地契》这样一个艺术活动,看到的由于土地失而复得又得而复失的社会变动,以及这种变动对社会最小单位的家庭——上至中国共产党的领导人,下至每一个普通农民家庭及其成员带来的伤害。

In the joint of LG PEX-A Pipe ,male xocket is pressed to a convex on the inserting part and the fastening ring will contract to fasten up the heating pipe by the fastening of outer nut,and there is also a convex on the ring to offer close coupling by mechanical re-press effect to prevent water from leaking in case of heat expansion.
在LG地热管中的连接部位不仅阀门管套插入部分的凸起部位被机械作用压密,而且随着外部螺母被拧紧,使紧固环收缩,从而带紧热炕暖气管,另外由于存在凸起部位,可通过机械作用进行再次压密,因此可防止由于热膨胀而引起漏水。
