The grafting rate and surface charge density of the pulp were also influenced by the reaction temperature, they increased from 20℃ to 50℃ and reached the maximum value at 50℃.

在浆浓较低时，随着浆浓的提高，接枝率和阳离子表面电荷密度提高，当浆浓超过11%时，接枝率和阳离子表面电荷密度下降。

Result: in substantial stage, thirty-four patients showed intrapelvic radioactive concentration imaging out of the baldder, in which sixteen were in the left side and eighteen were in the right. in delayed stage, radioactive concentration still existed, with the positive rate of 56.7%.

结果：34例在实质期内可见膀胱外盆腔大小不等的同位素浓聚显像，其中偏左侧16例，右侧18例，延迟期放射性同位素浓聚仍持续存在，阳性率56.7%。26例未见明显持续性同位素浓聚。

In order to solve these problems, first, activated carbon which was deashed by hydrochloride was modified through using concentrated sulfuric acid, concentrated nitric acid, hydrogen peroxide and potassium permanganate in the paper, the result showed that the modification of activated carbon is best through using concentrated sulfuric acid under 250℃ through analyzing the desulfurization efficiency and acidic oxygenous group on surface.

对上述问题，本文首先采用浓硫酸、浓硝酸、双氧水和高锰酸钾等氧化剂对盐酸脱灰后的活性炭进行化学改性，通过对改性活性炭的脱硫效果及其表面酸性含氧基团分析，得出在250℃的温度下采用浓硫酸改性活性炭效果最好。

Black-yonggu dahongyu reaumuria 2b pigments(ⅲ, pgment index number: p.R.48: 2, purple-red powder, insoluble in water and ethanol, in case of concentrated sulphuric acid radiofrequent purple-red, red is blue, in case of concentrated nitric acid, radiofrequent Rufous red concentrated sodium hydroxide, thermotolerance.

After some time, from the initial thalli places to the oil-water interface, the distribution law of microbial concentration was that the concentration increased monotonicly from the minimum to the maximum, that was to say, the nearer to the oil-water interface, the bigger the microbial concentration, and the concentration was the biggest at the interface.

经过一段时间后，从菌体初始位置至油水界面之间的菌浓分布规律为从最小值单调地上升为最高值，亦即离油水界面越近则菌浓越大，油水界面处菌浓最大。

The result showed that, rutile TiO2 was well consistent with carrier resin, so the prepared masterbatch had glabrous of surface, and application was better than acute TiO2; the masterbatch was prepared by using polymerization PE wax, whose application is better than masterbatch prepared by using other PE wax, such as hiding power of the film, whiteness of the templet; dispersion of TiO2 was uniformity, and application was improved, in particular hiding power and tinctorial power by adding PPA and nanocalcium carbonate in masterbatch.

结果表明，浓PE白色母粒的加工制备，样品中金红石型钛白粉与载体树脂相容性较好，载体树脂仍能形成连续相，制备出表面光洁的色母粒，且应用性能较优于锐钛型钛白粉；聚合型聚乙烯蜡制备的浓白色母粒，薄膜透过率较低，光密值较大，母粒的遮盖力强，注塑样板的白度高，母粒的着色力强，应用性能优于其它聚乙烯蜡；浓白色母粒中加入PPA和纳米碳酸钙，使钛白粉粒子的分散均匀，提高了母粒的着色力、遮盖力等应用性能。
