氟

The rate constants and yields of aromatic halides containing substitute s with different electrophilicities were investigated.

三氟乙酸钠在以CuI为催化剂的条件下与卤代芳烃进行取代反应，生成相应的三氟甲基化合物。

Novel Methods and Agents for Fire Suppression including the revolutionary environment friendly SFE Powder Aerosol Halon alternative and the unique Electro-magnetic Ion-wind extinguishing means;· Ecology oriented technologies including Electro-optical Monitoring of hazardous pollutants and toxic vapors/gases as well a novel approach to Halocarbon selective dissociation and neutralization in order to eliminate the Ozone Depleting CFC and Halons from existing systems /banks and prevent further damage to the environment.

这是一种氯氟烃和溴氟烃选择性降解和中和的新方法，这些物质存在于当前自然界中并能导致臭氧耗损，这项技术能够防止氯氟烃和溴氟烃进一步破坏环境。

BACKGROUND: Halothane and desflurane have been shown to attenuateneuronal injury; however, the effects of these anesthetics onmitochondria are unclear.

背景：氟烷和地氟醚已经被证实可以减轻神经元损伤，但是它们对线粒体的影响还不清楚。

Heart rate profiles during the induction of anesthesia differmarkedly between the administration of sevoflurane and halothane.

应用七氟醚和氟烷的麻醉诱导过程中心率的变化明显不同。

However, no previous reports have detected serum autoantibodies such as that reported with DILI from halothane or isoflurane.

然而，这些澥道中没有检测患者血清中的自身澗体，而既往的氟烷或异氟醚诱导的肝损害则检测过患者血清中的自身澗体。

These data indicate that cortical neurons remain responsiveto synaptic input during isoflurane and halothane anesthesia.

这些数据显示皮层神经元在异氟烷和氟烷麻醉时对突触输入仍有反应。

It is also found that pressure has no detectable effect on the free-energy change of inserting a halothane from bulk water to DMPC, and does not change the regional preference of halothane, either.

另外也发现压力对於三氟氯溴乙烷从纯水溶入 DMPC 的自由能改变所造成的影响很小，且对於三氟氯溴乙烷的偏好区域没有可观的影响。

Isoflurane and halothane cause electroencephalographicdepression and neuronal depression in the reticular formation,a site critical to consciousness.

异氟烷和氟烷在网状细胞结构（决定意识状态的关键之处）能产生脑电抑制和神经细胞抑制。

Further depression at 1.2 MAC halothane, but not isoflurane, suggests different sites of immobilizing action for these two anesthetics.

氟烷1.2MAC 时有进一步的制，异氟醚却没有，提示了两者固定作用的位点不同。

Onthe other hand, with increased isoflurane or halothane concentration,responses of ventral horn neurons were depressed by 60% and45%, respectively.

另一方面，随着异氟醚或氟烷浓度的提高，腹侧角神经元的反应为从被抑制60％变为了被抑制45％。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
