This generator adopts PSA transforming absorpion,which uses carbon molecule to separate Oxygen and Nitrogen from air. It transfers compressed air,which is originated from air source, into absovbing untis formed by two tower after oil removing, drying, filtering, purifying of the air. The compessedair generates Nitrogen when it is transformingly absorbed in one tower, then it is sent to another tower for regeneration. It alternately circulates between two towers, which can unceasing achieve 98%-99.9% of pure and cheap Nitrogen..

本设备采用PSA变压吸附原理，利用碳分子筛在压力变化时具有分离空气中氮的能力，以空气为原料，将压缩空气经除油、干燥、过滤等净化处理后，送入双塔组成的吸附组件，压缩空气在一塔内经加压吸附后产生氮气，而另一塔在解吸再生，两塔交替循环，即可不断地得到纯度为98－99.9%的廉价氮气。

METHODS: Twenty-one children with spina bifida who underwent the untethering operation for tethered cord syndrome at least 2 years ago were enrolled in this study. All patients had severe bladder dysfunction and received anorectal manometry examination.

采用多通道肛管直肠测压技术对因排尿功能障碍而来就诊的21例脊柱裂患者进行肛管直肠功能检测，入选患者皆已于至少2年前行脊髓拴系松解术。

The procedures are fixation, entire staining, isolation with acid, denudating ovule, transparence, pressuring cover glass and observation.

The bamboo was spread out and hackled into bundles after different pretreatments.The rupture strength and fineness of the bamboo bundles were measured.

竹束是竹材(包括竹秆、竹筒、竹片和竹篾等)通过碾压或锤击梳解成通长的、相互交联并保持纤维原有排列方式的梳松束状单元，可作为重组竹或木竹重组材的构成单元[1]。

The remnants of ellipticity in the parabolized stability equations for three dimensional parallel incompressible boundary layer flow are studied, detail methods for removing the ellipticity are suggested, and the consistence of solutions between the parabolized stability equations and the fully elliptic problem is provoed.

针对三维平行不可压边界层流动的抛物化稳定性方程，研究其剩余的椭圆特性，提出了消除该特性的具体方法，并对抛物化稳定性方程解与全椭圆问题解的一致性进行了证明。

The results show that the CNTs are dispersed effectively by bell jar immersing precast block casting. The maximal tensile strength and the elongation of the AZ31/CNTs composites are enhanced by 41.3% and 119.4%, respectively, and the elastic modulus and micro-hardness are also raised by 67.8% and 66.9%, respectively, when compared with those of the as-cast AZ31 Mg alloys. The CNTs can greatly refine the grains of the composites, playing a good role in reinforcing the matrixes of AZ31 Mg alloy. The fracture sections of the composites mainly consist of dimples and prisms, which demonstrates quasicleavage fracture modes.

结果表明：钟罩压块法可以有效地将碳纳米管分散到镁合金熔体中；CNTs对AZ31镁合金的力学性能有较强的增强效果，与本研究中的铸造AZ31合金相比，AZ31/CNTs复合材料的最大抗拉强度和伸长率分别提高41.3%和119.4%，弹性模量和显微硬度分别提高67.8%和66.9%；CNTs对AZ31镁合金基体晶粒的细化作用显著，与镁基体界面结合较好；复合材料试样断口形貌由韧窝和撕裂棱组成，呈现准解理断裂特征。
