挥发的

Apart from the effect of high temperature and ventilation on the volatilization of organochlorine pesticides, the degradation rates of HCH and DDT in the treatment without microbial inoculums were 37.2% and 14.9%, respectively.

试验结果说明，堆肥过程中高温和通气促使了HCH和DDT向气相中挥发，而该过程的生化反应有助于HCH和DDT等有机氯农药的降解。

A wide range of carbon-based molecules, such as aldehydes , ketones , and other light hydrocarbons are VOCs.

范围广泛的以碳为基础的分子，如醛，酮，轻质烃都是挥发性有机化合物。

This thesis investigated the VOC emission from drying of Chinese fir and Eucalyptus plantation lumber in a pilot-scale kiln.

本论文以杉木、尾叶桉为研究对象，对木材精油和木材生材在常温状态下释放的有机挥发物成分进行了分析研究，重点研究了木材在高温和常规干燥条件下VOC释放成分，释放规律及影响因素，评价了木材干燥过程中VOC释放对环境的影响，为有效合理控制VOC排放和制定其排放标准提供了基础数据。

Therefore,qualitative and quantitative study of plant volatiles is the premise for chemical ecology.

因此，植物挥发性物质的定性定量研究是化学生态学研究的前提。

These volatiles should not be in the lost in the factory, instead, they should be in the product presented to the consumer.

但是这些挥发性的化合物本不应该在工厂里损失掉，而是应该通过产品出现在消费者的面前。

We even use volatiles for chemical signals of our own—as ingredients for commercial perfumes.

甚至我们也利用植物挥发物作为自己的化学信号，如：流行香水中的成分。

Meantime,effect of volatiles on physiology and psychology were analyzed from angle of drug physiology and aromatherapy.

同时，从药物生理和芳香疗法的角度，初步分析了挥发物对人体生理、心理健康的影响。

The condenser should be hot enough to allow venting of some of the volatiles carried in the steam.

冷凝器的热度，应足以使蒸气中的一些挥发物质排出。

It was found that different substances and concentrations of volatiles influenced behavior reaction to A. glabripennis.

四臂嗅觉仪测定中，发现挥发性物质及浓度的不同，对光肩星天牛具有不同的行为反应。

In some cased, the Westphal balance is used, for example, in the determination of the relative density of a volatile liquid.

液体药品的相对密度，一般用比重瓶测定；测定易挥发液体的相对密度，可用韦氏比重秤。

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。
