The electrochemical behavior of chrysin in pH 2.0—9.0 Britton-Robinson buffer solutions was studied by the means of linear sweep voltammetry and cyclic voltammetry at a static mercury drop electrode.

采用线性扫描伏安法、循环伏安法等电化学手段在pH 2.0～9.0的B-R缓冲溶液中，研究了白杨素在静汞电极上的电化学行为。

MethodsThe cells of human gastric cancer cell line SGC7901 was treated respectively with Chrysin at different concentration 10、20、40、80μM for 48h.

As one who stands in dewless aspodel

正像你站在缺乏甘露的白杨中颤颠

Up his road, under his sky. His sky that started up from the fingery little poplars, misty and blue two concessions away, and curved up over the eighth and down to the gently rising land where the township ends.

赶路的他已然融入了自己的一片小天地里：从整齐的小白杨林开始，穿过两个租借地外的薄雾，攀绕过第八租借地，然后下去就是微陇起的平地就是镇区的尽头了。

The 60-km-long Bow Valley Parkway in the Canadian Rockies meanders though a montane landscape of trembling aspen and lodgepole pine.

在60公里长的弓河谷公园大道（封闭，交通运输在加拿大落基山脉卡车）河曲的颤抖，但白杨和山地景观，长满松树。

Subclones of the hybrid 741 took on a high insect-resistant identity to the larvae of leaf pests such as Clostera anachoreta Fabricius, Lymantria dispar Linnacus, Hyphantria cunea Drury ect., and the mean death rate of the grubs were all above the 85%, furthermore, the grubs' growth which survived could be restrained and the growth rate was reduced so that they couldn't tie cocoons as the usual.

项目简介：转双抗虫基因741杨是将部分改造BtCryIAc 基因与慈菇蛋白酶抑制剂基因，通过农杆菌介导法转化了优良白杨杂种741杨，并获得了一批具有高抗虫性无性系，对舞毒蛾和杨扇舟蛾，美国白蛾等鳞翅目幼虫死亡率达85%以上，并能抑制存活幼虫的发育，使其不能正常化蛹。

In order to explore molecular mechanism and inhibitory effects of flavones and flavonols on human esophageal carcinoma cells, the inhibition of proliferation and the induction of G2/M cell cycle arrest in KYSE-510 cells and OE33 cells treated with three flavones and three flavonols (quercetin, kaempferol, myricetin) were analyzed by MTT array and flow cytometry.

为了探索它们对人食管癌细胞的抑制作用和分子机制，采用MTT法和流式细胞术，鉴定了3种黄酮(木犀草素、白杨素、芹菜素)和3种黄酮醇(槲皮素、山奈酚、杨梅素)对2株人食管癌细胞(鳞癌KYSE-510和腺癌OE33)的增殖抑制作用和G2/M周期停滞的诱导作用。

Stands of birch and trembling aspen attest to a time when Jagiello's descendants were distracted from hunting, perhaps by war, long enough for these sun-seeking species to recolonize game clearings.

耸立的桦树和沙沙作响的白杨证明了亚盖洛的子孙后代们或许因为战争而无心狩猎；光阴荏苒，这些追寻太阳足迹的物种再次在曾经被烧得精光的土地上扎根生长。

The yard was quite dark as they turned into it and the poplar leaves were rustling silkily all round it.

他们走进院子里时，天已经完全黑了，周围的白杨树叶发出了轻柔的沙沙声。

The trees are clustered here and there with weeping willows,poplars,tender yulan and rare gingko.

安妮：校园环境也挺好，树木众多，有垂柳、有白杨、还有娇贵的玉兰、名贵的银杏。。。。。。

Do you know, i need you to come back
