In this thesis, seed germination and root elongation test, early growth test were performanced by chemical spiked (Cu, Zn, Pb and Cd; Phenanthrenen, Pyrene; and1, 2, 4-trichlorobenzene) in four types of soils (red load soil, meadow brown soil, chestnut soil and dark brown soil) using wheat, Chinese cabbages , tomatoes , turnip and scallion as plants: The toxicity of heavy metals Cu.

本文选择4类典型土壤（红壤、草甸棕壤、暗棕壤和栗钙土），以（小麦、白菜、萝卜、西红柿、大葱）为供试植物，进行了重金属（Cu、Zn、Pb、Cd）、有机氯、多环芳烃污染的植物种子发芽与根伸长抑制试验；植物早期生长试验研究；以草甸棕壤为供试土壤，进行了重金属（Cu、Zn、Pb、Cd）单一、复合污染条件下的蚯蚓急性毒性实验；以草甸棕壤、污染土壤和生物修复土壤进行蚕豆根尖实验和土壤原生动物实验。

Loneliness is flower blooming statically, loneliness is a cup of tea of rich fragrance, and loneliness is a glass of liquors elegant mellowness.

孤独是一朵花静静的绽放，孤独是一杯茶氤氯的浓香，孤独是一杯酒飘逸的芳醇。

As a kind of novel photochromic material, diarylethenes have been under widely research due to excellent thermal stability, good fatigue-resistance, fast response, and high conversion degree. Their latent applications are of memory, molecular switch, multi-color display, and light-driven molecular motors.

作为新型的光致变色材料，二芳乙烯化合物由于其良好的热稳定性、优良的耐疲劳性能、较快的响应速度及高的光转化率，近年来已成为有机光致变色研究的热点，其应用主要集中在光信息存储、分子开关、多彩色显色器、光驱动分子机器等。

By a strict interpretation of the rules, Merkle was forced out at second, and the game winning run nullified.

按严格解释规则，张国芳被迫外出二、游戏赢来说无效。

However, Fred Merkle was on first and ran to the clubhouse instead of advancing to second base, partly because the fans were mobbing the field at the Polo Grounds and partly because it was not entirely customary in that era to run out game winning hits.

但是，张国芳被检首次走入会所而非晋级第二基地因为球迷都在外地聚众马球理由不完全是因为习惯在那个时代办出游戏赢点击。

At the present time, the raw material was chiefly from the fraction of reforming plant, in which the content of mesitylene is very low and must be pre-treated.

目前，生产均三甲苯的原料主要来源于重整C_9芳烃塔底油。

Besides fuel oil,mesitylene can be mainly used in production of 1,3,5-benzenecarboxylic acid,1,3,5-triaminobenzene,antioxidant Lonox-330 and so on.

重整重芳烃中的均三甲苯除了用作燃料油组分外，还可以用于制备均苯三甲酸、均苯三甲胺和抗氧剂Lonox 330等高附加值产品。

The initial SAR studies indicated:(1) the presence of a linker of methene at the N-1 may be beneficial to anti-HIV activity, while longer chain could enhance toxicity;(2) substituted phenyl at the C-2 could reduce toxicity;(3) 6-substituted benzimidazoles generally showed higher anti-HIV activity than 5-substuted ones;(4) the presence of a halogenated benzyl ring at the N-l would enhance anti-HIV potency and decrease cytotoxicity.

初步构效分析提示：(1)苯并咪唑环1位侧链间隔基为亚甲基时活性最好，侧链延长，毒性增大；(2)苯并咪唑2位侧链无间隔基毒性相对较低；(3)苯并咪唑6位取代活性高于5位取代；(4)苯并咪唑1位芳环用卤素取代，毒性明显降低。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
