The principal of buffer is described as follows.At impulsing down,the piston moves down and vacates the annular space.The pressure in respiratory cavity decreases to a certain level and the traveling valve opens.At that time,the liquids enter into traveling valve and cavity and the plunger is impulsed upward to carry out the gentle transient at the sudden change.When the upward impulsing begins,the respiratory cavity is subjected to pressure and the traveling valve closes.During the gradual pressure rising,the liquids in respiratory cavity effuse from the upper ventage and the sudden change of force-summing direction of plunger is relieved relying on the resistance of ventage.

其原理大致是：下冲程时，活塞向下运动，让出环形空间的体积，呼吸腔内压力下降，下降到一定水平后，游动阀打开，此时，游动阀和小孔同时进液，使柱塞在从上死点处突然改变方向向上运动时得到缓冲，实现了柔和过渡；当上冲程开始时，呼吸腔受压，游动阀关闭，在压力逐渐上升的过程中，呼吸腔内的液体从上部的小孔流出，并依靠小孔的阻力使柱塞受力突然换向得到缓冲。

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。

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。

The change of frequency, draws the conclusion through observing fish's respiratory rate and coughing: Luo is not the respiratory rate of fish and bright cloud porgy, drop with increase of Cu2+ density, cough frequency increases with increase of Cu2+density; Respiratory rate and frequency of coughing of black carp, appear downward trend after rising with Cu2+ increase of density first.

通过观察鱼呼吸频率和咳嗽频率的变化，得出结论：罗非鱼和彩云鲷的呼吸频率，随着Cu2+浓度的增加而下降，咳嗽频率随着Cu2+浓度的增加而增加；鲫鱼的呼吸频率和咳嗽频率，随着Cu2+浓度的增加都呈现先上升后下降的趋势。

People in their daily lives the use of breathing, is a kind of instinctive, normal physiological movement, playing in the trombone breath used in almost all different from the normal breathing.

人们在日常生活中运用的呼吸，是一种本能的、正常的生理运动，而在长号演奏中所用的呼吸基本都不同于平常的呼吸。

Bed partners almost invariably make the observation that the larger their snoring spouse becomes, the louder the snoring bellows, and the more often they hear snoring pauses followed by snorts, and a resumption of breathing (i.e., apneas -- episodes of obstructed breathing).

睡在一起的人会发现，他们的配偶越胖鼾声也就越大，也就更频繁的听见喷鼻息后的鼾声暂止，然后又重新呼吸。（也就是&呼吸暂停&—一段时间内没有呼吸）。

Methods:To observe the projection and breath machine treatment condition, 24 premature infants who suffer from the HMD were given the infusion PS inside the windpipe and treated by use of the breath machine, and set against with 36 HMD's premature infants who treated simply by the breath machine same period.

方法对24例患HMD的早产儿在呼吸机治疗的基础上，给予气管内注入PS，并与同期单纯用呼吸机治疗的36例HMD患儿进行对照，观察两组患儿的呼吸机条件及预后。

Exhalations arise from earth as well as from sea; those from sea are bright and pure, those from earth dark.

呼吸既来自土也来自海；来自海的呼吸是明亮和纯洁的，来自土的呼吸是黑暗的。
