The principle of determination of sound absorption coefficient of materials by transfer function method is introduced.

介绍了在阻抗管中采用传递函数法测量材料吸声系数的原理，详细介绍了使用双传声器进行测量的方法，指出了测试的频率范围取决于阻抗管的管径大小和传声器布置的位置。

The cost of this accident will be reduced to the lowest if we reduce the repair time and lessen the water cut range. As a result, analysis of pipe burst is one of the most important spatial analysis functions. Its effective realization consists of three aspects: the high quality data, the topological relation of data and the algorithm.

因此爆管关阀分析是供水管网地理信息系统中重要的空间分析功能之一，它的有效实现是由三个方面组成的：首先是数据录入时要生成高质量的数据，它是前提；其次是数据拓扑关系的建立，它是核心；最后是爆管分析的算法，它是关键。

In this paper, the oxidation conditions of MWNT, especially the acidification time was optimized.

因此碳管在很多领域有潜在的应用价值，尤其是碳管的刚性和高强度使它可以成为高强材料的增强剂。

The hydrothermal method is used to obtain two types of TiO2 nanotube catalysts, to which the vitriol with different density is applied to acidify them.

利用水热法制备了两种TiO2纳米管催化剂，用不同浓度硫酸对制备得到的TiO2纳米管进行酸化。

Between P14 and P21,CIAPIN1 immunoreaction in the brain,heart and liverbecame much lower. However,between P21 and P28,CIAPIN1 immunoreactionin the heart,brain,liver and skeletal muscle became much lower,while with thekidney development,CIAPIN1 immunoreaction in the kidney became higher. Invarious tissues from adult mouse,CIAPIN1 immunoreaction could be seen incardiac muscle cell,brain,hepatocyte,epithelium of renal tubule,skeletal muscle,lung tissue,gastric mucosa and gland,acinus lienalis.2. Distribution of CIAPIN1 in normal fetal and adult human tissuesTo reveal the possible physiological role of CIAPIN1,we examined theexpression and distribution of CIAPIN1 in fetal and adult human tissues usingimmunohistochemistry. We found that CIAPIN1 was ubiquitously distributed infetal and adult tissues,and was localized in both the cytoplasm and the nucleus.

然而，在3个月大的成年鼠中，CIAPIN1阳性反应物在心、脑、肝和肾小管中的表达强度要低于P28小鼠；但CIAPIN1阳性反应物在成年鼠骨骼肌中较P28小鼠高。2、CIAPIN1蛋白在人5个月胚胎及成人多器官组织内的表达在人5月胚胎多器官组织中，CIAPIN1阳性反应物见于心脏、胆囊单层柱状上皮和粘膜、结肠粘膜、小肠粘膜和绒毛、肝脏、直肠腺体、胃粘膜、肾上腺束状带、甲状腺滤泡、脾索、胸腺小叶间隔、皮肤真皮层和汗腺、睾丸白膜和间质、脑组织内神经元和神经胶质、肺小支气管和肺泡、骨骼肌、肾脏皮髓质和肾小管、子宫内膜、胰腺腺泡和胰岛、卵巢、输卵管粘膜等绝大多数组织细胞。

In addition, compound cooling system of thermoelectric cooler and heat pipe cooler is discussed qualitatively.

另外，对热电-热管复合制冷系统进行了初步的探讨，即对热电冰箱热端用带液池的重力热管散热器进行了定性的分析。

The fluence and frequency of laser was controlled precisely, which could melt and destroy the adiposis tissue without damage to the adjacent tissues. The histological study of treated adiposis tissues, post-operative reaction and clinical results were observed and studied. Results Local adipose tissues were melted and liquefied effectively by the laser. Compact fibrous tissues of cellulite were broken by the laser into loosen structure. The bleeding was lower than traditional method due to the coagulation of capillary vessels. The advantages of laser lipolysis included less edema, petechia and complications, which produced a rapid recovery and satisfactory results.

但该方法也存在疼痛、血管损伤、出血较多[1]等不足，此法主要是利用机械力插入负压吸引管，通过较强的负压将脂肪组织吸出体外，比较适用于大范围、厚层次和疏松的脂肪吸除，难以应用于小范围局限致密的脂肪组织，如面颈部和手臂部等，这些部位脂肪构成较特殊，包含有大量坚韧的呈网状交织的纤维结缔组织，质地较紧密，普通负压难以吸除，吸脂管插入和抽动阻力较大，如强行反复抽吸对组织创伤明显，因此，有必要寻找一种更加有效的治疗方法。

Adventitia, media and lumen cross-sectional area, wall thickness of the aorta were assessed with computed video processing.

测量收缩压和血管壁胶原含量，计算机图像分析血管外膜面积、中膜面积、管腔面积和管壁厚度。

I picked some different sizes of aerofoil tube at the hobby store today when getting more brass rod and tube.

我挑选了一些不同规模的翼型管在嗜好商店今天，当越来越黄铜棒和管。

The top of neural tube forms basic encenphalic shape,namely endbrain, interbrain, midbrain and afterbrain. The abnormal closure of neural tube will result in neural tube detects. Encephalocoele is a common congenital malformation whose mechanism was no known. NO participates in the physiologic process of brain.

胚胎脑发育的早期阶段主要是神经板隆起、弯曲、闭合形成神经管，神经管的头部从前向后依次发育形成脑的基本组织形态，即端脑、间脑、中脑、后脑，在神经管闭合过程中出现异常就会导致NTD。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
