The molecular weight of sppms was in the range of 4x 104g / mol to 10 x 104g / mol, and the molecular weight distribution was from 1.6 to 6.0 p-甲基苯乙烯与苯乙烯共聚时，p-甲基苯乙烯共聚能力高于苯乙烯，二者倾向于无规共聚，仍为间规聚合物。
Either a longer lasting night, or a super night ( moonwells regen at like 2x or 3x or 4x normal night rate ), so you could still even use it at night time to increase regen 或是一个更长的夜晚，或是一个超级夜晚（月井恢复速度是平时的2-4倍），这样你才能在夜晚用到它去提升月井的恢复速度。

A mathematical transformation algorithm precisely reconstructs the spectrum with a 4x signal-to-noise improvement as compared with a slit-based system equipped with identical source, grating and detector components, and 70-80x greater than with a fiber input of equivalent resolution 一个数学转换元算法则精确地改造了光谱，在使用相同的光源、光栅和探测原件的情况下，与传统的基于狭缝技术的系统相比，新的光谱仪将信噪比提高了四倍，而进光量提高70-80倍。
The prepared sdse modified zirconum meinbrane was tested at the wider range of tcmperaure and pressure and differellt composihons of hydrogen mixturc gases ( i . e . different hydrgen panal pressure ) in order to examine the performance of this membrane and the sole hpermselechvity of the membrane . the results showed tha the purity of the permeated hydrgen is l00 % at the base of the detection greatest lower lanit of the qhle mass spectrometer, and there was no impurity gas passed, the permeating flux and permeability of this membrane are from several decades times to one decade times more higher than tha of a palladum membran in the range of from 593k to 773k, puv = 0.2 ~ 0.3mpa, pdn = 4x l04pa-- 0 . lmpa, the hydrogen permeatng flux is increased with the difference of the squto root of pressure, and presents a linear relationship, the pressure seems has no influence on the permeablity, the permeabi1ity is decreased with the increasing of the temperature, and presents an exponential relationship, accondng to the fitting curve of the relationship betwen the permeability and the temperatur derived from the experimenta daa, in the range of 593k ~ 773k, pup0.2 ~ 0.3mpa, pha = 4 x l0 # pa ~ 0 在更宽的温度范围、压差范围内，在不同原料气组成(即不同的氢气分压)条件下，对所制备的锆表面改性膜进行了渗氢性能实验，考核了膜对氢的唯一选择渗透性，结果表明：在四极质谱的检测下限内，只有氢气存在，而无杂质气体通过；在593k773k温度范围内，锆表面改性选择渗氢膜具有高于钯膜数十倍至十几倍的渗氢流量和渗氢系数；其渗氢流量随着膜两侧氢分压平方根摘要差的增大而增大，并且呈线性关系；压力对膜的渗氢系数几乎无影响；膜的渗氢系数随着温度的升高而下降，井巨呈指数关系：根据对实验数据所作渗氢系数与温度关系曲线的拟合，在温度593k773k范围内，压差p、0二0
