浓

Of course, there will one day these young trees will be aging dying, but as long as those on campus in Punta Nongyin had their own green shade in the motherland, had its own concentration, which is enough!

当然，总会有一天这些年轻的树会衰老凋零，但只要校园里那蓬浓阴里有过自己的绿，祖国的浓荫里有过自己的浓，这就足够了！

Results EROD activities in liver of wild crucian from Zhangtan, Jiangjunyan, Fuyang and Wenyan (23.51±4.17, 16.79±7.39, 18.74±5.16, 18.65±8.86 nmol/) were significantly higher than that of Jiekou (7.84±2.42 nmol/g promin), and no difference was observed between the other sites and Jiekou. Three dose groups (0.25, 0.50, 1.00L/dish water sample extracts) were used in Ames test. Reversional mutation rate of TA98 colony exposed to extracts from Zhangtan was 2.21, 3.39, 6.95 without S9, and 2.70, 4.07, 6.23 with S9, respectively. The revesional mutation of TA100 colony was 2.55, 2.81, 5.36 without S9, and 1.73, 2.86, 4.14 with S9, respectively. Reversional mutation rate of TA98 colony exposed to 1.00L/dish extracts from Jiangjunyan with S9 was 2.22, and there was a dose-response relationship in reversional colony count. Ames tests of the other extracts were negative.

The literature about the synthesis of the ion exchange and chelating adsorbents used in the off-line separation and preconcentration of the noble metals and the development of the on-line microcolumn separation and preconcentration of the noble metals were reviewed. Four silica gel-based adsorbents with rhodanine, 2-mercaptopyrimidine, 2-mercaptothiazoline and isophenylthiourea as the functional groups were first synthesized and applied to the on-line separation and preconcentration of silver, gold, palladium and platinum for their FAAS determination.

本论文在回顾螯合吸附材料的合成及其在贵金属的离线和流动注射在线预浓集分离发展状况的基础上，首次合成了含罗丹宁、2-巯基嘧啶、2-巯基噻唑啉和异二苯基硫脲等四种以硅胶为载体的螯合吸附剂，并用于银、金、钯和铂的流动注射微填充柱在线预浓集分离、火焰原子吸收光谱分析。

The high concentration of salt treatment and the thin alkaline treatment both of whom are used in extracting ribonucleic acid from waste beer yeast were studied in this work.

本文对浓盐法和碱法提取啤酒废酵母中的核糖核酸技术进行了研究，并对这2种方法进行了比较和优化，提出了浓盐法与稀碱法相结合提取核糖核酸的工艺技术路线，酵母中核糖核酸的提取率达90%以上，样品的纯度达90.3%。

High concentration white masterbatch is prepared by using different titanium dioxide, PE wax and adding nanocalcium carbonate etc. to change the formulation of masterbatch in this paper. Hiding power, tinctorial power and dispersion performance were tested by color measure instrument and IBAS, and process performance, rheology were tested by Brabender torsion rheometer and INSTRON rheometer.

本文采用不同的钛白粉、聚乙烯蜡及添加纳米碳酸钙等助剂的方法改变浓色母粒的配方，加工制备浓白色母粒，通过测色仪、图像分析仪测试母粒的着色力、遮盖力和分散性能，通过转矩流变仪和INSTRON流变仪研究了母粒的加工性能和静态流变性能。

With the starting material intermediate titanyl sulfate and meta-titanic acid of titanium white product by sulfuric acid process,the titanium dioxide and iron content have been determined.

以硫酸法钛白粉生产工艺中间体浓钛液和偏钛酸为原料，分析了浓钛液中二氧化钛和铁的含量。

Due to the DesignJet 5000 is a six-color business card printing and membership card equipment, with an additional light green and light magenta inks, so the software can use digitally simulated dot gain and waterish the effect of wet trapping to print out and business card printing and membership card product the same multitoning Rose leaf patterns.

由于DesignJet 5000是一款六色制卡和会员卡制作摆设，带有出格的不浓青和不浓品赤色油墨，因此软件可以用数字办法模仿网不面放大和湿压湿陷印的成果，从而打印不入与制卡和会员卡制作产物不异的半色调玫瑰斑斑纹。

It's thick, but you can still easily ladle it out by tilting the pan.

面汤浓，但浓到你依然可以将锅子倾斜后轻易舀出。

Under the limitation of production cost and the requirement of mass production, pulp concentration is basically processed by filtrating and press.

纸浆浓缩工艺受生产成本的制约及大规模生产的要求，基本上只能采用低浓段过滤和高浓段挤压的方法进行浓缩。

Upon the grass of the great plains the crooked bare old thorn-trees were scattered, and the grass was spiced like thyme and bog-myrtle; in some places the scent was so strong, that it smarted in the nostrils.

大草原上，光秃秃的有些地方香味很浓，荆棘林曲折蔓延地散生着；棵棵青草芳香馥郁，像百里香，像香桃木；有些地方香味很浓，扑鼻而来。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
