结果表明，采用钌钛涂层电极为阳极，不锈钢为阴极，以紫脲酸为介体对杨木硫酸盐浆进行无隔膜电化学处理，能有效脱除纸浆中的残余木素，而浆的黏度损失较小。

Zooxanthellae isolated from these two corals also had different bleaching rate in cultured condition under light. Those of A.

在简单轴孔珊瑚的白化过程中，各类不同的色素会因为环境的压力而有不同的变化趋势。

The same phenomenon was also observed in laboratory experiment A. austera bleached within two days in 33℃. The bleaching process included losing the number of zooxanthellae and the reduction of the pigments in zooxanthellae.

而实验室中的白化实验也发现：简单轴孔珊瑚在水温33℃时，第二天即开始白化，而白化时珊瑚不仅共生藻数目会减少，其单位共生藻的色素量也会减少。

At this stage the coral is still alive, and if the water cools, the coral can regain its zooxanthellae.[28] If the water does not cool within about a month, the coral will die of starvation. Australia experienced its warmest year on record in 2005. Abnormally high sea temperatures during the summer of 2005-2006 have caused massive coral bleaching in the Keppel Island group.

在这个阶段，珊瑚仍是活的，如果水温下降，珊瑚可以重新获得共生藻；如果约一个月内水温未下降，珊瑚将死于食物短缺。2005年是澳大利亚史上气温最高的一年，2005与2006年夏天异常的高温导致了凯珀尔岛群的珊瑚大量白化。

The chemical components of eucalyptus and their changes during the alkali sodium sulfite pretreatment and peroxid bleaching process had been studied by FTIR.

用傅里叶变换红外光谱法对桉木中各组分在碱性亚钠法化机浆预处理及漂白过程中的化学变化进行了研究。

In order to remove the impurity accreted on the cotton and flax fiber, such as pectin, lignin and so on, the floret silk/flax and floret silk/cotton fabric were in need of scouring and bleaching, and we use W100 and H_2O_2 to treat them.

为了去除棉、麻纤维上的果胶、术质素和色素等杂质，提高染色的效果，我们采用了精炼剂W100对坯布进行精练，然后用双氧水漂白，收到了较好的效果。
