In the second chapter of part one, a lipophilic fluorescent dye, coumarin-6,serving as a nanoparticle probe, was incorporated in Lf-NP_ to investigate its braindrug delivery characteristics in a bEnd.3 BBB model with unconjugated nanoparticleNP_(PLGA as control.

第一部分第二章采用香豆素-6作为纳米粒的荧光探针，bEnd.3作为体外BBB模型，以未连接Lf的普通纳米粒NP_为对照，对Lf-NP_的脑内递药特性进行了体外评价。

In DMSO, the polymerization of methyl methacrylate could be carried out efficiently. However the photopolymerization was inhibited in acetonitrile. It was ascribed to the complex formed between coumarin 1 and HTIB photolyzed to unreactive species after irradiation in acetonitrile.

在一般极性溶剂中如DMSO中能有效地引发甲基丙烯酸甲酯光聚合，而在电子受体性质的极性溶剂如乙腈中，光聚合反应受阻，这归结于香豆素1与羟基苯基碘鎓盐形成络合物，使得光反应后生成不具活性的产物。

This product not only contains rhodopsin, flavonoid and anthocyanidin glucoside, but also is replenished with seabuckthorn (containing VA, VC, VE, VK, VB1, VB2, flavonoid, and coumarin etc.) and concentrated carrot essence, which make it more nutritious and easier to be absorbed by the body.

蓝莓果精不仅保留了蓝莓果中的天然视紫质和类黄酮、花色素甙等成分，而且因添加了沙棘含有维生素A、C、E、K、B1、B2、黄酮类、香豆素等）、胡萝卜浓缩素，使其营养成分更加丰富并且更容易被人体均衡吸收。

Other chemicals that are available are Apiin, apiol, bergaptein, myristicin, pinene, glycoside, camphor, petrocelinic acid, furanocumarine, iodine, and phosphorus.

还有其他例如芹黄苷，洋芹醚，香柑脑，肉豆蔻油醚，蒎烯，葡糖苷，莰酮，岩芹酸，香豆素，碘，磷等化学元素，这些都能蕴含在欧芹叶中。

The autotoxicity is one of the mechanisms and obstacle effects occurred from continuous cropping.

自毒作用是连作障碍的发生机制之一，该作用主要是由有机酸、醛类芳香酸、香豆素、醌类、生物碱和类萜等植物次生代谢产物及其分解产物所引起的。

The benezoxazolocoumarin dyes substituted with methyl or chlorine on 5'-position showed bathochromic shift of the maximum absorption and fluorescence emission.

香豆素类荧光染料在5'-位有取代基可使最大可见吸收波长和荧光发射波长产生红移；当共轭双键长度增加，可使染料颜色变深(Ⅴ：544，Ⅵ：552)。

Quinone methides, generated in situ from the reaction of 4-hydroxycoumarin with benzaldehyde, formaldehyde and pentanal, underwent the Diels-Alder reaction with silyl enol ethers to give a series of 3,4-dihydro-2H,5H-pyrano[3,2-c][1]benzopyran derivatives in high yields.

通过4-羟基香豆素与苯甲醛、甲醛和戊醛缩合产生的quinone methide与烯醇硅醚的Diels-Alder反应，以较高产率合成了一系列含有硅氧基的3，4-二氢-2H，5H-吡喃并[3，2-c][1]苯并吡喃-5-酮衍生物。

Different e--donors and e--acceptors are incorporated at the phenyl ring of the benzothiazole to decipher the relationship between basicity of nitrogen atom and thermochromic phenomenon.

我们并且合成出其他不同的电子与体及电子受体的香豆素衍生物，来说明取代基的立体效应与电子效应对整个热致变色现象的影响。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
