Nowadays the single tube and single-unit hydroelectric station have been used widely and skillfully, but it is necessary for some large hydropower stations to use tailrace bifurcated tubes, just as Xiaolangdi, Xiangjiaba, Baishe project and so on. So it is significant to study the transients of long tailrace tunnel with tank or without tank.

对于尾水系统，单管单机的布置方式比较成熟，尾水岔管的布置方式目前在大型电站中用的较多，如小浪底、向家坝、百色等，因而研究其在有尾水调压井和无尾水调压井的情况下的过渡过程，很有实用意义。

Unicellular gland was goblet cell, which was lied in two sides of tongue, esophagus, ileum and rectum. Multicellular gland was included uniacinar gland on palate, multiacinar gland on esophagus and unitubular gland on ventriculus and intestine. The digestive gland of liver and pancreas was got into initial jejunum through one duct.

结果表明：单细胞腺为杯状细胞，主要分布于舌两侧、食道、回肠和直肠；多细胞腺由单泡状腺的颌间腺、复泡状腺的食道腺和单管状腺的胃腺与肠腺组成；肝脏和胰脏消化腺通过一条导管共同开口于空肠的起始部。

Result］the total operative effective rate of double-tube diastematomyelia amounted to 86% during a follow-up period of 6 months to 15 years,more significant in patients with pain.the scores of neural function and ptncsep were significantly improved.

结果］双管型脊髓纵裂通过手术后观察和6个月～15年(平均2年6个月)的随访发现，临床神经功能评分及 ptncsep术后有明显改变，尤其是疼痛为主诉的患者恢复最为明显，手术的总有效率可达86%；单管型脊髓纵裂手术前后无明显变化。

Result］The total operative effective rate of double-tube diastematomyelia amounted to 86% during a follow-up period of 6 months to 15 years,more significant in patients with pain.The scores of neural function and PTNCSEP were significantly improved. But patients with single-tube diastematomyelia had no obvious change after operation.

结果］双管型脊髓纵裂通过手术后观察和6个月～15年(平均2年6个月)的随访发现，临床神经功能评分及 PTNCSEP术后有明显改变，尤其是疼痛为主诉的患者恢复最为明显，手术的总有效率可达86%；单管型脊髓纵裂手术前后无明显变化。

According to the classification, there were single-tube in 25 and double-tube in 96 patients. One hundred and two patients with diastematomyelia were treated by operation and ninteen by conservative treatment. The clinical results were retrospectively analyzed according to scoring neural function and monitoring the peak P40 of posterior trivial nerve cortical somatosensory evoked potential before and after treatment.

方法］对1978年5月～2006年1月收治的有完整资料的121例单管型及双管型脊髓纵裂手术及非手术治疗的病例进行回顾性分析，并通过临床神经功能评分及胫后神经皮层体感诱发电位P40波峰监测，评价其手术治疗的疗效。

Based on Chen's correlation and our experimental data, a new revised correlation was proposed for the calculation of frictional pressure drop of gas liquid two-phase flow in helically coiled tubes oriented with various axial angles.

在对试验结果及前人研究结果进行详细分析的基础上，获得了第一个能适用於不同倾角放置螺旋管的单相及汽液两相摩擦阻力计算式，从而为汽液两相摩擦阻力及螺旋管的进一步研究和应用提供了依据。

The Practical and New patent is to strack automatically the movement of the sun by a small sync unit using a mirror paraboloid and focus the sunsine on the surface of vacuum heat absorbing pipe, so as to heat the water in a single vacuum heat absorbing pipe with several times of energy,so that the water temperature rises till boils with heat exchange.

家用同步跟踪太阳能开水器是利用镜面抛物面在小型同步装置作用下自动跟踪太阳运动，以7倍于阳光直射的能量将阳光聚焦到真空吸热管的表面，对单根玻璃真空吸热管中的水进行加热，通过对流热交换，使容器中水温上升直至沸腾的太阳能开水器。

Raman spectrum and UV-vis-NIR absorption spectrum show that the above procedure does not change the electronic structures of single-walled carbon nanotubes. Moreover, the infrared spectrum confirms the formation of amide bond between ammonium sulfamate and carbon nanotubes.

Raman光谱和UV-vis-NIR吸收光谱表明，上述处理过程没有改变单壁碳纳米管的电子结构；此外，红外光谱的研究说明氨基磺酸铵与碳纳米管是通过酰胺键连接起来的。

The lowest rating boiler efficiency, the smallest heating area and the disposition of blast blower and inducing fan in energy conservation design standard for new heating residential buildings are analyzed and the relative suggestions are advanced.

本文认为为达到按户计量的良好效果，供暖系统应在设计时考虑到室内温度的可调性，因此应改变传统的没有跨越管的单管顺流式系统，提出了适应既有和新建住宅建筑按户计量的系统形式。
