PH between 4 .0-5.5 time, with the pH value increases, the conversion rate and increases with selective. The introduction and flow, when the same aging time, with the increase of aging temperature, the catalyst of conversion and selectivity increases; When the aging temperature the same, as the aging time, the catalyst for the conversion and reduced choice. Along with the increase in precipitation temperature, the catalyst powder bulk density increases; With the increased bulk density, catalyst for the conversion and selectivity decreased.

转化率是conversion rate不是transform rate
cocurrent可能得改改
还有was the same
催化剂是catalyst不是activator
沉淀化学里都用这个词precipitate,（这是名词）
deposition是沉积物，沉积作用
cocurrent可能得改改
还有was the same
催化剂是catalyst不是activator

When the PH value was between 4.0 and 5.0, along with the increase of the PH value, transform rate and selectivity also increased. Adopting the cocurrent, when the aging time was same, along with the increase of the aging temperature, the transform rate and selectivity of activator also increased; when the aging teperature was same, along with the increase of aging time, the transform rate and selectivity of activator decreased. Along with the increase of deposition temperature, the powder density of activator increased, which would lead to the the transform rate and selectivity of activator decreased.

100%的对! 决无错误!
PH is between 4.0-5.5, with the increase of pH, conversion ratio and the alternative, with increasing. Adopt and flow, when aging time is the same, with the increase of aging temperature, the conversion ratio of the catalyst and alternative increase; When aging temperature is the same, with aging increase of time, conversion ratio and choose, reduce of catalyst. With precipitating the increase of temperature, the powder material of the catalyst piles the density to increase; With piling the increase of the density, the conversion ratio of the catalyst and alternative decrease.

PH value when 4.0-5.5, along with pH value increasing, the conversionrate and the selectivity along with increases. Uses and the class,when the aging time is same, along with the aged temperature increase,the catalyst conversion rate and the selectivity increases; When theaged temperature is same, along with the aging time increase, thecatalyst conversion rate and the choice reduces. Along with theprecipitation temperature increase, the catalyst powder material pilesthe density to increase; Along with piles the density increasing, thecatalyst conversion rate and the selectivity reduces.
