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。

As the trough of D, E and the slot F (it belongs to the other end of spiral) of the sealing surface of convergence, there is a triangle similar to a positive gap a'b'c ', so D, F, E will also be connected.

由于在槽D、E与槽F相衔接的密封面上，也存在着类似于正面的三角形缺口a'b'c'，所以D、F、E也将相通。

As the slot D, E and slot F (it belongs to the other end of spiral) converging sealing surface, there are also similar to the front of the triangle gap a'b'c ', so D, F, E will be connected.

由于在槽D、E与槽F相衔接的密封面上，也存在着类似于正面的三角形缺口a'b'c'，所以D、F、E也将相通。

Result:Eight compounds were elucidated as β amyrin palmitate, taraxastery acetate, luteolin 7 O α L rhamanopyranosyl (1→2)β D glucopyranoside,luteolin 7 O β D glucopyranoside, triacontanic acid,β sitosterol, stigmasterol and stigmast 7 en 3β ol.

结果 ：从全草中分离得到 5个化合物，β香树脂醇棕榈酸酯，蒲公英醇乙酸酯，木樨草素 7 O α L 鼠李糖基(1→ 2 )β D 葡萄糖苷，木樨草素 7 O β D 葡萄糖苷，三十碳酸；1个混合物，β谷甾醇、豆甾醇、豆甾 7 烯 3β醇。

Effects of gamma irradiation on shoot regeneration from leaf and bud growth in vitro of strawberry 1 The leaf was very sensitive to the gamma irradiation, and 'Toyonoka' was more sensitive than 'Akihime'. The LD50 (50% decrease of generation) of strawberry leaf was between 10 and 20 Gy. 2 Strawberry leaves were inoculated in vitro at 8 d-15 d after gamma rays irradiation, and the shoot regeneration rate from of 'Toyonoka' increased at 10 Gy and almost no difference from 20 Gy to 40 Gy. The positive effect dose for 'Akihime'.was from 10 Gy to 30 Gy, however, 40 Gy decreased shoot regeneration rate.

2.60Co γ辐射对不同品种草莓离体叶片再生及芽生长的影响 1）叶片对辐射敏感，叶片再生的半致死剂量为10 Gy-20 Gy，'丰香'品种比'章姬'品种敏感； 2）辐射后8 d-15 d接种，'丰香'叶片的不定芽再生率在剂量10 Gy呈上升趋势，而其他剂量则几乎未见有变化，'章姬'在剂量10 Gy-30 Gy，叶片的不定芽再生率提高较大，40 Gy仍表现轻微下降； 3）适宜的辐射剂量对草莓试管苗增殖有促进作用。

By azo compound became chromophore monomer disperse red -19, and through Sulfonyl of the compound was synthesized by the C, and through 1HNMR its structure was characterized, the results show that the synthesis of compounds C of very high purity, synthetic polymers can meet at the request of the monomer, but also of the compound D, through 1HNMR its characterization, showed that high purity compounds D, is expected to be functional after the adoption of To all the excellent performance PEEK electro-optic polymer materials.

本文通过偶氮化合成了生色团单体分散红-19，并通过磺酰化反应合成得到了化合物C，并通过核磁共振氢谱对其结构进行了表征，结果表明，所合成的化合物C的纯度非常高，完全能满足聚合物合成时对单体的要求，同时也合成了化合物D，通过核磁共振氢谱对其结构表征，显示化合物D纯度很高，应有望通过后功能化合成出各种性能优良的聚醚醚酮电光高分子材料。

If a child in the spring to provide food less calcium, and vitamin D were more children blood to the bone calcium deposition, caused by the concentration of calcium in the blood decreased, resulting in children tetany, which is usually referred to "ventilation" or "cramp", which also can be found in taking more vitamin D and calcium intake fewer children.

如果在春天给孩子提供含钙的食品较少，而维生素D较多时，孩子血中的钙会向骨骼沉积，而引起血液中钙的浓度下降，从而导致孩子手足搐搦，也就是通常所说的"抽风"或"抽筋"，这种情况也可见于服用较多的维生素D而钙摄入较少的孩子。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
