Tin is less reactive than the metal it covers, protecting the underlying metal from corrosion. Monomers involved in condensation reactions typically contain two reactive groups within the molecule. And by making the particles chemically reactive, scientists are building exquisitely sensitive sensors that can detect individual molecules. Derived chiefly from petroleum and coal tar, aromatic hydrocarbons tend to be reactive. 1.3Physiology Showing an immune response to a specific antigen. 反应（性）的；对刺激反应灵敏的 Example sentencesExamples Arrows indicate cells reactive to the zeatine specific antibodies. Traditional antivirus protection is very reactive in nature. Eyebright appears to make your immune system less reactive to airborne allergens. Several methods are available to prevent the formation of preformed reactive antibodies to HLA antigens. Equivocal or weakly reactive immunohistochemical stains may require further testing to make the diagnosis of mesothelioma. 1.4 (of a disease or illness) caused by a reaction to something. （疾病，不适）由过敏反应引起的 reactive arthritis 过敏性关节炎。 reactive depression 过敏性抑郁症。 Example sentencesExamples Therefore, elevation of the control site temperature helped mask temperature increases caused by reactive hyperemia or inflammation in some cases. Patients may suffer from anxiety, depression and reactive adjustment disorders. He told me that he has been diagnosed as suffering from reactive depression and is currently being treated for that by a psychiatrist. The etiology of a pulmonary exacerbation is likely a variety of airway insults including respiratory viral infections, reactive airway disease, and pollutants. Reactive arthritis occurs most frequently in men 20 to 40 years old. He may be suffering from reactive depression resulting from traumatic events whilst living in Kosovo.

Hilar lymphadenopathy with other pulmonary infiltrates is infrequent and thought to represent reactive hyperplasia. For those patients with reactive airway disease, pre-medication should be considered. 1.5Physics Relating to reactance. 〔物理〕电抗性的，无功的 a reactive load 电抗性负荷。 Example sentencesExamples There are separate accumulators for generator tripping and 500-kV reactive power compensation switching for this algorithm as well. It is important to remember that any reactive load will produce standing waves on the line. If this angle is zero degrees, the load is purely resistive; if the angle is not zero, there is some reactive loading, or additional storage in the system. If active and reactive power are not properly balanced, voltage collapse may occur in one part of the system and could propagate system failure. Generator tripping must be technically and contractually feasible, and the reactive power devices must be in place.
