呼吸

The rate of respiration of adult schistosomes was found to be 1.47+0.19 nmol O2/pair of worm/min or 6.89+1.13 nmol O_2/mg dry wt/min. It was 2.5 fold higher than that obtained by manometric method. This indicates that S. japonicum did have an active aerobic metabolism.

结果表明：酒石酸锑钾对虫的呼吸呈明显的抑制；吡喹酮对虫的呼吸先刺激，在作用1 h后则表现为轻度抑制；在对呼吸有显著影响的浓度下，对虫的糖酵解并无明显影响。

Objectives: We attempt to determine if obstructive sleep apnea leads to higher incidence of positive microvolt T-wave alternan; thus higher risk for arrhythmic death; and correlate MTWA result with severity of OSA as measured by apnea hypopnea index.

目的：我们研究阻塞性睡眠呼吸暂停综合症是否导致阳性微伏级T波电交替发生率增加从而使得致死性心律失常发生的风险增加；由呼吸暂停低通气指数确定的严重睡眠呼吸暂停综合征是否与微伏级T波电交替相关。

objective to discuss perioperative complication and management of patient with high risk copd following esophagectomy.methods 45 patients with high risk copd underwent esophagectomy with epidural block combined with general anesthesia.perioperative treatment included smoking cessation,chest physiotherapy,prevention and control of infection of air way and appropriate bronchodilators of air way,breathing exercises,nutrition support and oxygen therapy.painkiller was instilled after surgery,early exercises,ensuring unobstruction of the air way,mechanical ventilation was applied when needed.results 3 had hypoxaemia in operation.after surgery,all patients had spo2 somewhat declined.6 had lung infection.6 were removed of bronchial secretion by bronchoscope.2 were supported by ventilator by using intubation.2 underwent tracheotomy.1 had disturbances of acid base balance and treated by using hydrochloric acid muriatic acid.all patients recovered rather smoothly and discharged from hospital.conclusion high risk copd is not the absolute contraindication of esophagectomy.active management before and after surgery ensures the safety and recovery of patients.

目的 探讨重度慢性阻塞性肺疾病简称慢阻肺病人食管切除术围手术期常见并发症及其处理。方法 45例重度慢阻肺的病人在全麻联合硬膜外阻滞下进行开胸食管切除手术，围手术期处理包括术前戒烟、胸部理疗、预防和控制呼吸道感染、解痉化痰、呼吸功能锻炼、营养支持和氧疗；术后硬膜外镇痛、早期锻炼、保持呼吸道通畅，部分病人予以呼吸支持。结果术中3例出现低氧血症。术后所有病人pao2均有不同程度的下降，6例出现肺部感染，6例行纤维支气管镜吸痰，2例通过气管插管给予呼吸机支持，2例行气管切开术，1例酸碱平衡紊乱使用盐酸精氨酸治疗。所有病人均痊愈出院。结论重度慢阻肺病人并非开胸食管切除手术的绝对禁忌证，积极的术前准备和严格的术后管理可减少和控制术后急性发作，有助于确保此类病人的围手术期安全和康复。

This paper chose Carbendazim, Daconil, Imidacloprid and Methomyl as experiment objects, determined their influence to soil respiration of field, shed and school using obturate direct absorb method; discussed not only the variety of soil respiration under different pesticide's sorts, concentration and soil conditions but also the relationship between soil respiration and the variety of bacteria number in soil; confirmed the toxicity grade and dangerous index; provided an scientific basis for environment safety evaluation of pesticide's using.

因此，本论文选取多菌灵、百菌清、吡虫啉、万灵为受试农药，用密闭直接吸收法测定了农药对三种土壤（农田土、大棚土和校园土）呼吸作用的影响；讨论了农药种类、浓度、土壤条件的改变引起的土壤呼吸作用强度的变化及土壤呼吸量与土壤中细菌数量变化的关系；确定了农药的毒性等级和危害系数，为农药使用的环境安全性评价提供科学依据。

Orthopnea and paroxysmal nocturnal dyspnea are unusual in pulmonary disease, except in a very advanced phase when the increased efficiency of breathing in the upright position is manifest.

肺病患者的端坐呼吸和阵发性夜间呼吸困难不常见，除非是在很晚期，此时，直立位呼吸功率增加明显。

A 78-year-old woman presented with marked dyspnea, orthopnea, and paroxysmal nocturnal dyspnea. Eight years earlier, she had receied a bioprosthetic mitral ale because of mixed mitral-ale disease.

患者，女性，78岁，因呼吸急促，端坐呼吸、阵发性夜间呼吸困难就诊。8年前，她由于复杂的二尖瓣疾病进行了二尖瓣的生物瓣植入术。

Her chest pressure is constant, moderate in intensity, nonradiating, nonpleuritic, and nonpositional. She has no paroxysmal nocturnal dyspnea, orthopnea, or lower-extremity edema.

患者胸部压迫感呈中度持续性，无放射，与呼吸运动和体位无关，无夜间阵发性呼吸困难，无端坐呼吸，无下肢水肿。

Carbon dioxide production during photorespiration may be up to five times greater than in dark respiration.

光呼吸产生的CO2量可能是暗呼吸中的五倍还多，光呼吸在过氧化物体而不是在线粒体中进行，并且不与氧化磷酸化藕联。

Photorespiration is a process in which oxygen uptake and CO2 release occur in light. A C3 plant may photorespire as much as 25% of the carbon fixed by photosynthesis, such that engineering photorespiration could improve photosynthesis.

光呼吸 是绿色植物在光下吸收氧气并释放CO2的过程。C3植物光呼吸可消耗掉25％左右的光合产物，故合理改良光呼吸可望提高植物的光合效率。

Objective To develop a new type of respiratory inductive plethysmograph to achieve high signal-noise rate and low system power cost, and also to eliminate the cross-talk between chest and abdominal band sensors. Method Either of the two bands was powered by a very high power oscillator in a very short time, and these two bands were switched on in turn.

目的 为解决呼吸感应体积描记技术存在的高信噪比与低系统功耗之间的固有矛盾，并消除胸、腹信号耦合干扰，研发一种新型的呼吸感应体积描记技术，并以可穿戴技术的设计理念，设计出可穿戴式呼吸感应体积描记系统。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
