As the maneuverability of the model of 800 t ship with double tail fins didn′t meet the design standard,this article turned the twin skeg of the models into tail-shaft strut,and then made tur-ning tests and Z shape tests.

针对某一采用双尾鳍形式的800 t级排水船在进行自航模试验时出现操纵性能不能满足设计要求的情形，文中将其尾部的双尾鳍改成轴支架，并在某露天操纵性水池中，对改进后的自航模进行了回转和Z形操纵试验，通过对实验结果进行比较发现合理设计轴支架的大小和安装位置能够较好地改善800 t级排水船的操纵性能，并能够满足给定的船舶操纵性能设计要求。

Right now the nurse answers with gentle language, patient manner sucks phlegmy necessity and importance to patient and family member specification, and the serious consequence that rejects to suck phlegmy likelihood to bring about, and signal patient and gentleness of movement of family member operation, at the same time directive and sober patient cooperates to may decrease those who suck phlegmy place to bring is unwell, cooperate in order to obtain what the patient reachs a household. Whether do the 5 distances that check tracheal spile to be apart from fore-tooth have fluctuant reach auscultation sound of double lung breath is symmetrical. Sound of breath of 6 auscultation double lung, in order to judge the place of phlegmy fluid. The 7 patients as a result of tracheal spile, what aeriform exchange does not pass nose pharynx ministry is wet change, make inside tracheal spile drier, reason should time do pulverization inspiratory 2 / D~4 second / D, arrive in order to rise the wet path that spend energy of life, avoid the end with phlegmy scabby fluid.

此时护士应以暖和的语言，耐心的态度向病人及家属说明吸痰的必要性和重要性，以及拒绝吸痰可能导致的严重后果，并示意病人及家属操作动作轻柔，同时指导清醒病人配合可能减少吸痰所带来的不适，以取得病人及家属的配合。5检查气管插管距门齿的距离是否有变动及听诊双肺呼吸音是否对称。6听诊双肺呼吸音，以判定痰液的位置。7由于气管插管的病人，气体交换不经过鼻咽部的湿化，使气管插管内较干燥，故应定时做雾化吸入2次/d~4次/d，以起到湿化气道、防止痰液结痂的目的。
