The appearance of-enantiomer after incubation with single-enantiomer revealed the enantiomeric inversion of-isomer to its antipode. While no obvious stereoselective degradation or enantiomeric inversion were observed in other test soils.

左右旋对映体在3~#土壤中的降解速率有明显差异，二者半衰期相差0.95周；添加外消旋体培养6周后ER值达到1.65，表明左旋体被优先降解；同时在该土壤中存在左旋体向右旋体的转化现象；在其他几个土壤中均未有明显的选择性降解或对映体转化现象。

PAHs ratios are used to identify the source of PAHs, the result showed that the major source of 16 PAHs in Urumqi Xinshi district was coal-bustion and vehicle discharges . Mercury in TSP samples were digested by aqua regia and analyzed by AFS analyzer .The results showed that : the concentration of mercury was 0.869-1.91 ng m-3.Compared with other cities in the rest of the world , the concentration of mercury was very high. The concentration of mercury in heating season was lower than that in no-heating season.

对大气颗粒物样品中的汞，采用王水于特弗龙消解罐中加热消解的方法进行处理，稀酸定容后采用原子荧光光谱法对样品中的汞进行测定，测定结果为。869-1.91 ng m-3，与国外城市相比较高；实验测得非采暖期乌鲁木齐大气颗粒物汞浓度的均值高于采暖期颗粒物中的汞浓度，其原因可能是由于随着非采暖期温的升高，长期积累在土壤、水体环境中的汞向大气中释放，附着在颗粒物上，过了燃煤的影响。

The characteristics of ASCUS in postmenopausal women is that the rate of cervix diseases is low, and the prognosis of ASCUS is good. All senile patients who had cervical diseases were infected by HPV, which suggests that detection and therapy of HPV infection is important to prevent senile cervical diseases for ASCUS in postmenopausal women.

绝经后妇女的ASCUS特点是宫颈病变的比率低，表明其转归较好；有宫颈病变的老年患者均感染HPV，提示ASCUS中的绝经后妇女HPV的检测及治疗对于预防老年宫颈癌发生有重要意义。

As the hydraulic system works, the capacity of oil box will change at any moment. When the capacity decreases, the air will enter the moisture absorption after filtered. The desiccant in the absorption sorbs the moisture, then the desiccated air bursts through the entry single way valve and comes into the oil box, at the same time the atmosphere outside the oil box will close the deflated single way valve.

液压系统工作时油箱液面会随时发生变化，当液面下降时油箱外的空气被滤清器过滤后，进入吸湿器，吸湿器内干燥剂吸收空气中的水分，干燥后的空气推开进气单向阀进入油箱，同时油箱外大气关闭放气单向阀。

After carrying out Moderate Criterion Devise in the experiments of mathematical teaching, the author make amazing discovery that two classes with the same lever pre-experiment turn out to be no striking difference pro-experiment...

Rodriguez isn't the only Yankee who needs a good October. When he looks around the clubhouse, he sees more teammates who have never won a title in New York than those who have. And thanks to the Rangers' picking up $67 million of the money left on his contract when he was traded to New York, Rodriguez can find three players in the same room to whom the Yankees are paying more this year -- Jeter ($21 million), Giambi ($19 million) and righthander Mike Mussina ($19 million)-- and a fourth, lefthander Randy Johnson, to whom they pay an equal amount ($16 million). Next year the Yankees will pay outfielder Bobby Abreu ($17.5 million) more than Rodriguez, making A-Rod a veritable bargain. I point out all of this to Rodriguez early this month as we walk underneath the first base stands at Yankee Stadium toward the indoor batting cage.

A-Rod并非洋基阵中唯一需要藉由季后赛杰出表现来证明自己价值的球员，环顾球员休息室，尚未为洋基拿到冠军戒指的队友甚至多过曾经办到的人，感谢游骑兵队愿意分担他天价合约中的六千七百万美元额度，在洋基阵中有三位球员从洋基老板的口袋中拿到比A-Rod更多的薪水– Jeter， Giambi，以及Mussina，另外还有和A-Rod并驾齐驱的Randy Johnson，下个球季洋基要付给Bobby Abreu的薪水也将超越A-Rod，这让A-Rod的交易看起来简直划算到不行，本月初，在一次和A-Rod一同走向洋基球场中的室内打击练习场时的谈话中，我向他提及这些数据
