漂白

The results of simulating multi-stage H〓O〓 displacement bleaching showed that the brightness of bleached pulp increased along with the increase of H〓O〓 concentration in fresh bleach liquor.

多段H〓O〓置换漂白的模拟试验结果表明，漂后浆白度随新鲜漂液H〓O〓浓度的提高而提高，但在相同的新鲜漂液H〓O〓浓度下，不同漂液量时的漂后浆白度基本相同。H〓O〓消耗量随新鲜漂液H〓O〓浓度和漂液量的下降而下降，漂白效率的变化恰与H〓O〓消耗量的变化相反。

Secondly, study on bleaching of sandstone based on field characteristics, petrography, geochemistry and compared with other sandstone related, combined with geological setting of gas seepage in the area, reveals that natural gas leakage is responsible for bleaching of the sandstone on top of Yan\'an formation. The bleaching resulted from interaction between the reductive fluid and the rock. At the same time the bleaching suggests that the northeast of basin has experienced large scale gas seepage.

在此基础上，通过漂白砂岩野外露头地质特征、岩石学、地球化学以及相关砂岩的对比研究，结合研究区天然气逸散的地质背景，揭示砂岩漂白现象为上古生界天然气逸散过程中，还原性流体与岩石作用的结果，同时也表明其指示了天然气的大规模逸散作用。

Results: Haemoglobin and haematin were detected in the dentinal tubules of discolored teeth from group A and no evidence of ferric or haemosiderin. Specimens from group B demonstrated a negative response to histochemical tests.

组织化学实验结果显示：变色牙牙本质小管内存在高铁血红素和血红蛋白，缺乏铁离子和含铁血黄素：漂白后的牙本质小管内未见任何红细胞的分解产物。B组变色牙漂白4周后染色均消失，牙齿颜色恢复正常。

And it was found that: certain good effects could be obtained in wood color improving treatment by single bleaching; the effects were not obvious using the prescriptions of sulfides; but the effects were obvious using the prescriptions of hydrogen peroxide or Javel water, and good bleaching effects could be gained.

结果发现：单纯漂白可获得一定的材色改良效果；硫化物类药剂配方，效果不明显；双氧水类、次氯酸钠类药剂配方，效果明显，可得到很好的漂白效果。

Loofa obtained from traditional market was cut into approximate 1 cm in length and then treated with 1 N sodium hydroxide at 85 oC for 4 hours. The pulp like suspension was bleached by 25 % sodium hypochloride until the fiber turned colorless and the pulp was washed by distilled water to remove excess hypochlorite. The white pulp was again filtered and lyophilized to make into a paper-like membrane.

将购自传统市场之菜瓜布，裁剪出大约1公分长之纤维，再於浓度1 N的氢氧化钠之溶液加热至85 ℃处理4小时，以25 %之漂白水将此纸浆状之悬浮液漂白，使其纤维褪色后再以蒸馏水清洗以去除次氯酸盐，最后将此白色悬浮液过滤及冷冻乾燥，制成纸状的薄膜。

Beyond bleaching technique has no evident bad influence on vital tooth pulp, so it is a safe bleaching technique.

Beyond冷光牙齿漂白技术对活髓牙牙髓无明显不良影响，是一项安全可靠的漂白技术。

Cellulose fibre and blended polyester fabrics are normally bleached using hydrogen peroxide or sodium hypochlorite .

纤维素纤维和混合的涤纶一般用过氧化氢或次氯酸钠来漂白。有时也用亚氯酸钠来漂白。

"I have observed sites before and after bleaching in Okinawa, Japan, and it was remarkable to see a massive disappearance of soft corals," said marine biologist Hudi Benayahu, head of the Porter School of Environmental Studies at Tel Aviv University.

&在漂白作用之前和之后，我曾经在日本冲绳的海域的几个点观察过，看着大量的软珊瑚在漂白作用后失踪，这让我不能忘怀。&特拉维夫大学波特环境学院院长，海洋生物学家Hudi Benayahu说。

Laundry soaking time: put some salt to prevent leg color; white dress and add 23 drops of blue ink can be bleached; vinegar Although the bleaching effect on clothing, but there are corrosive, clothing fibers can become brittle, it is recommended not to use!

答：衣物浸泡时间：把一些盐，以防止腿色，白色礼服，并添加23滴蓝墨水，可漂白，虽然在衣物漂白作用，但有腐蚀性的醋，衣物纤维可变脆，建议不要使用！
