Benzoxazine compounds are one kind of highly active protoporhyrinogen oxidase inhibitors. These compounds can effectively control both monocotyledon weeds and dicotyledon weeds at lower dosage. The action mechanism is similar to p-nitro-o-substituted diphenylethers. They can result weeds albinism and decolorization, which are very important albinism herbicide.

苯并噁嗪类化合物是一类高活性的原卟啉原氧化酶抑制剂，低剂量可有效地防除禾本科与阔叶杂草，其作用机理和对硝基邻位取代的二苯醚类似，它们造成白化或脱色，是白化除草剂中较重要的种类，其活性远超过二苯醚除草剂，是目前化学农药研究领域的热点。

Based on the quotient of difference being the grey derivative's whitening values in the GM(1,1) direct modeling method, direct modeling method of GM(1,1) with a step by step optimum grey derivative's whiting values is put forward.

在 GM(1，1)直接建模法以差商作为灰导数白化值的基础上，提出了一种逐步优化灰导数白化值的方法。

This study clearly showed that mosaic variation was caused by chlorophyll deficiency mutation of shoot tip histogen layer-Ⅱ;tissue and organs originated from the layer-Ⅱ couldn't synthetize chlorophyll,thus induced albino; the albino variation appeared yellow green mosaic because layer-Ⅱ was displaced by layer-Ⅲ partly.

研究表明，其变异原因是由于茎尖分生组织的L -Ⅱ组织原层发生失绿突变，致使其衍生的组织和器官不能合成叶绿素，从而形成白化现象；又由于L -Ⅱ与L -Ⅲ组织原层层间发生部分代换，致使白化突变呈黄绿镶嵌的花斑。

Two gene fragments of DEN-1(GenBank accession number DQ886390)and DEN-2(GenBank accession number DQ886391),differentially expressed between the ocular skin tissues of normal and albino turbot,were isolated by mRNA differential display and sequenced.It was confirmed by RT-PCR method that the expression levels of both DEN-1 and DEN-2 were down-regulated in the ocular skin tissue of albino turbot.The sequence homology search of DEN-1 revealed high sequence homologies with the UGGT genes of zebrafish and cattle,and the Ugcgl1 gene of Norway rat.High sequence homologies of DEN-2 were observed with the eya4 gene(the eye absent homolog 4)from red jungle fowl,zebrafish,human,Norway rat,mouse and dog.

应用mRNA差异显示技术，对比研究正常与白化大菱鲆有眼侧皮肤组织，克隆差异表达基因，经测序，RT-PCR 验证，差异表达基因片段DEN-1(GenBank登录号：DQ886390)与DEN-2(GenBank登录号：DQ886391)均在白化大菱鲆有眼侧皮肤组织中下调表达；通过BLAST检索发现，DEN-1与GenBank中的斑马鱼和牛的类似尿苷二磷酸-葡萄糖：糖蛋白葡糖基转移酶基因、与挪威鼠类似尿苷二磷酸-葡萄糖：神经酰氨葡糖基转移酶1(Ugcgl1)基因有较高同源性；DEN-2 与原鸡、斑马鱼、人、挪威鼠、家鼠和狗的眼缺乏同源框4(eya4)基因的同源性均较高。

The maximum quantum yield, zooxanthellae density, chlorophyll a concentration and protein concentration of non-bleached and bleached colonies of the reef coral Acropora intermedia were measured in inlet of The Third Nuclear Power Plant of Nanwan Bay in southern Taiwan.

本研究监测比较台湾南部南湾核三厂入水口海域，数量丰富但曾发生白化之中间轴孔珊瑚未白化与白化群体的最高光效率(maximum quantum yield， Fv/Fm)、叶绿素a含量、共生藻密度与蛋白质含量。

For this reason, the old methods can not fally meet the need of engineering practical application.3 By analyzing the principle and expound the methods of thecand the gray relationship clustering, the gray clustering matrix and method are presented.The gray clustering is a method that gather some obseration quotas or obseration objects to be some definable classification according to the gray relationship clustering matrix or gray albescent authority function.

3分析了灰色白化权函数聚类和灰色关联聚类的原理并阐述了其具体方法，提出了诊断变压器内部故障的灰色聚类模型和方法，灰色聚类是根据灰色关联矩阵或灰色白化权函数将一些观测指标或观测对象聚集成若干个可定义类别的方法；对结构复杂的大型电力变压器等电气设备的故障诊断，首要的问题是如何根据反映变压器故障的特征量指标来正确判断待诊设备是哪一类故障。

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。

Coral reef bleaching, the ecological phenomenon of whitening of reefs, result from the loss of symbiotic zooxanthellae and /or a reduction in photosynthetic pigment concentrations in zooxanthellae residing within the gastrodermal tissues of host animals, and death of coral reef could be caused by serious bleaching.

珊瑚礁白化是由于珊瑚失去体内共生的虫黄藻或者共生的虫黄藻失去体内色素而导致五彩缤纷的珊瑚礁变白的现象，严重的白化可以带来珊瑚礁的死亡。

As many as 10000 albinos are in hiding in east Africa over fears that they will be dismembered and their body parts sold to witchdoctors, CNN reported. Body parts of albinos are sought in some regions of Africa because they are believed to bring wealth and good luck.

据美国有线电视新闻网报道，东非有上万白化病人正四处藏匿躲避追杀，因为该地区有种愚昧的观念认为，白化病人的身体能带来财富和好运，该地区许多白化病人因此被残忍杀害并肢解，器官被贩卖给巫医。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
