过氧化

Methaemoglobin loses its ability to bind oxygen and causes hypoxia in the affected individuals. The condition is characterized by headache, weakness and breathlessness, and a bluish discolouration of the skin and mucous membranes called cyanosis.

这是因为亚硝酸盐使体内红血球素中的铁由亚铁氧化成正铁，正铁血红蛋白失去携氧能力，造成血氧过少，令人感到头痛，虚弱，呼吸困难，皮肤和黏膜会变成紫蓝色，医学上称为发绀。

We synthesized polynitrobenzenes by oxidation of polynitroanilines by peroxysulfuric acid (hydrogen peroxide dissolved in sulfuric acid, it is also known as Caro's acid) several years ago.

我们曾在若干年前用过硫酸(过氧化氢溶于硫酸中，亦称卡洛氏酸)氧化多硝基苯胺而合成了多硝基苯类(硝基数3至6)。

All patients with secondary osteoporosis caused by all endocrine diseases including Cushing's disease, hyperthyrosis, hyperparathyroidism, capsula glandulae thyroideae or thyroid hypofunction and diabetes, and patients whose bone metabolism was interfered by grave diseases were excluded. Three months before the trial, the patients did not receive any drug that could interfere the bone metabolism or affect endothelin, such as estrogenic hormone, calcitionin, nitrogen monoxidum, glucocorticoid. In addition, the patients suffering from bone fracture within 1 year or grave cardio-cerebrovascular disease, which had intimate correlation with endothelin, liver and kidney disfunction were eliminated.

所有纳入病例均排除以下患有引起继发性骨质疏松症的各种内分泌疾病者（如柯兴氏病、甲状腺功能亢进、甲状旁腺功能亢进、甲状腺囊肿或机能低下、糖尿病等）；其他严重疾病干扰骨代谢者；测试前3个月内未使用过雌激素、降钙素、一氧化氮、糖皮质激素等干扰骨代谢或对内皮素有影响作用的药品；测试前1年内无骨折；患有严重心脑血管等与内皮素水平相关密切之疾病及肝肾功能异常者。

Igh concentrations of H〓O〓 and MV caused oxidative injury to antenna system, and led to the decline of qNP, especially in chilling-susceptible cultivars.

〓O〓和MV对水稻不同耐冷品种荧光参数的影响不同浓度的H〓O〓和MV处理水稻幼苗，常温下两品种的Fo都下降，qNP增加，但过高浓度会对天线系统造成氧化胁迫，使qNP下降，而且冷敏感品种对活性氧的增加更敏感。H〓O〓和MV处理加剧水稻的低温伤害。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
