The results showed that under the prerequisite of constant color properties of colored products without affecting the properites of the product, nano-BaSO4 could be used as a substitute of partial pigment, and the maximum proportion is up to 30%.

结果表明：在不改变被着色制品色彩性能的前提下，纳米BaSO4可以替代部分颜料，替代最大比例可达到30%。在色母粒浓度为50%时，纳米BaSO4替代颜料的效果最好。

This character is same as the viscous dampers, can thus provides constant additional damping ratio independent of the movement amplitude and unchanging the vibration frequency of structures as well.

因而可以像粘滞阻尼器一样既可以提供随运动幅值变化的阻尼力，又不改变结构的振动频率。

The study of room temperature stability of P colloid emulsion shows the carboxylfunctionalized colloid particles cannot stay in water for a long time, but can be preserved after vacuum desiccation.

同时指出P乳胶粒子的水乳液不可长时间静置存放，但真空干燥后的乳胶粒子粉末可长期保存而不改变粒子形貌。

Under the same experimental condition as ever but changing the frequency of magnetic field, we discover that descaling is the best when the frequency of magnetic field is 700 Hz.

在其它实验条件不变的情况下，若仅改变电磁场的频率，发现当频率为700赫兹左右时除垢效果最佳。

Consequently, the fundamental approach to optimize the replacement effect is to adjust the positions of infalls and outfalls and influx, which changes the field structure finally.

因此，在引水量不变的前提下，优化西湖水体置换效果的根本途径就是调整进出口位置和流量，以改变流场结构。

Some people don't have the chance to live the experience of that marvelous interface because the interfaced devices are expensive.
