The method involves exposing the cells to a compound having the formula I in which: w is a nucleic acid x is a non-amino acid or non-peptide nucleic acid binding group y is a spacer having a chain length equivalent to 1-30 carbon-carbon single covalent bonds or is absent R4 is H or halogen or CH2O-R3; and R1, R2 and R3 are the same or different and are either hydrogen, methyl, ethyl, alkyl, alkenyl, hydroxylated alkyl, hydroxylated alkenyl groups or ether containing alkyl, alkenyl, hydroxylated alkyl or hydroxylated alkenyl groups optionally being an acyl group having a carbon chain length equivalent to 3-24 carbon atoms saturated or unsaturated, with the proviso that at least one of R1, R2 or R3 includes a group having a carbon chain of 3-24 carbon atoms saturated or unsaturated, or to a compound having the formula II in which: w is a nucleic acid x is a non-amino acid or non-peptide nucleic acid binding group y is a space having a chain length equivalent to 1-30 carbon-carbon single covalent bonds or is absent, R5 is alkyl, alkenyl, hydroxylated alkyl, hydroxylated alkenyl group or ether containing alkyl, alkenyl, hydroxylated alkyl or hydroxylated alkenyl group optionally being an acyl group having a carbon chain length equivalent to 3-24 carbon atoms saturated or unsaturated, with the proviso that R5 includes a group having a carbon chain of 3-24 carbon atoms saturated or unsaturated.

该方法包括使细胞暴露于具有式的化合物，在式中：w是核酸，x是非氨基酸或者非肽核酸结合基团，y是具有等于1―30个碳―碳单共价键的链长的间隔基或者不存在，R4是H或者卤素或者CH2O－R3；R1、R2和R3是相同的或者不同的并且是氢、甲基、乙基、烷基、链烯基、羟基化烷基、羟基化链烯基或者包含烷基、链烯基、羟基化烷基或羟基化链烯基的醚，任选地是来源于具有等于3―24个碳原子的碳链长的饱和或不饱和脂肪酸的酰基，其条件是R1、R2或者R3的至少一个包括具有3―24个碳原子的饱和或不饱和碳链的基团，或者使细胞暴露于具有式的化合物，在式中：w是核酸，x是非氨基酸或者非肽核酸结合基团，y是具有等于1―30个碳―碳单共价键的链长的间隔基或者不存在，R5是烷基、链烯基、羟基化烷基、羟基化链烯基或者包含烷基、链烯基、羟基化烷基或羟基化链烯基的醚，任选地是具有等于3―24个碳原子的饱和或不饱和碳链的链长的酰基，其条件是R5包括具有3―24个碳原子的饱和或不饱和碳链的基团。

Human's body is composed by the compound,while the compound also is composed by the chemical element.

人的身体是由化合物组成的，而化合物又是由化学元素组成的。

The special high levels of chlordane in soils might be attributed to the use of the substance in the vicinity.

通过化合物浓度与其对映体比值的对比，认为个别高值点主要受氯丹使用的影响，其手性化合物对映体比值接近原始值(0.5)。

It is noted that the effects of substitution on the C-Cl BDE of substituted chlorobenzene compounds are very insignificant.

研究了目标化合物的前线轨道能级差，并对取代氯苯化合物的热稳定性做了评估。

Like chlorofluorocarbons once used in aerosol cans, as coolants in air conditioners, and halon that puts fires out fast.

比如曾经用于喷雾罐的含氯氟烃化合物，空调内的冷冻剂，用于快速灭火的碳卤化合物等。

The results show that the synthetic compounds conform to the target compounds and the primary bioassay for anti-vibrio activity displays that the pyrrole alkaloids have a weak inhibition against Vibrio parahaemolyticus and Vibrio alginolyticus compared with the positive control of chloromycetin.

结果表明，所合成的化合物与目标化合物结构相一致。初步的抗溶藻弧菌和副溶血弧菌活性筛选表明，合成的吡咯生物碱具有一定的抗弧菌活性，但相对于阳性对照药氯霉素来说，合成的绝大部分吡咯生物碱抗弧菌活性较弱。

There is only one Schiff base chromophore in its molecules and it has less innermolecular strains.

由以上分析可见，化合物的分子结构对化合物的光致变色性质存在着影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
