By removing high valence counter ion and controlling ion conductivity constant , 65 % ( in volume ) concentrated suspension with viscosity of 1Pa · s was successfully prepared .

同时研究了Al2O3悬浮体中的可溶性离子及离子电导率常数，通过去除高价反离子及控制离子电导率常数，制备出了固相体积分数高达65%（粘度约为1Pa·s）的高浓度悬浮体。

PI-1 oligomers show low complex melt viscosity ( < 1Pa · s ) at 280 ℃ and are stable at this temperature , which mean PI-1 oligomers can be processed by resin transfer molding techniques .

PI-1低聚物在280℃时表现出低的熔体粘度（<1Pa.s）和良好的熔体粘度稳定性，可用于RTM成型工艺制备树脂基复合材料；

Compound molecular pump is set the merits of the two pumps in one . This pump has a larger pumping speed and higher compression ratio over a wide pressure range ( 10-6 ~ 1Pa ), which greatly raised the pump outlet pressure .

复合式分子泵集两种泵的优点于一体，在很宽的压力范围内（10-6～1Pa）具有较大的抽速和较高的压缩比，大大提高了泵的出口压力。

The results indicate that , when the content of acetate starch is 0.5 % ~ 1.5 % ( mass fraction ), the apparent viscosity of alumina slurry , which is always less than 1Pa · s , increases with the content .

结果表明：酯化淀粉添加量在0.5%~1.5%（质量分数）范围内时，淀粉-氧化铝陶瓷浆料的表观粘度随酯化淀粉添加量的增加而上升，但均小于1Pa·s；

These cryopumps are capable of providing a nominal gross pumping speed of 576m 3 · s - 1 , regulated with inlet valves for throttle control of the exhaust particle flow in the case of high neutral pressure ( > 1Pa ) in the divertor .
