Pt-inserted nanotube titanic acid was prepared as follows: H_2PtCl_6 ethanol solution was filled into the titanic acid nanotubes and then annealed in air at 673 K for 3 h.X-ray photoelectron spectroscopy showed that H_2PtCl_6 has been converted to Pt~0 and PtO.The result of electron spin resonance revealed that there are single-electron-trapped oxygen vacancies to be formed in PNTA after heat treatment in air.

通过在真空条件下将氯铂酸的乙醇溶液引入到钛酸纳米管内，再经过热处理制备了镶嵌铂的纳米管钛酸。X射线光电子能谱表明氯铂酸大部分转变成Pt0和PtO，顺磁共振谱表明在PNTA中生成了束缚单电子的氧空位，在紫外-可见扩散漫散射谱谱上表现出对可见光有吸收能力。

EDF, a state-controlled energy company, is laudably careful with French taxpayers' money.

而EDF作为法国的国有能源公司，能做到&不用纳税人的钱为高管的天价薪酬买单&，真是难能可贵啊！

Monotubular heater is an important apparatus in Bayer process of alumina extraction used in Pingguo Aluminum Company. However, since several years cracking in its weld joints occur and the production process is then interrupted by leaking of liquor.

单管预热器是平果铝拜尔法生产氧化铝的重要设备，经常在其焊缝区发生开裂泄露，影响生产，必须对造成其开裂的主要原因进行研究并提出有效的防护措施，以延长其使用周期。

At first, by pushing the adult mouse right testis into the abdominal cavity and suturing the inguinal canal, the inducing germ cell apoptosis model was created by cryptorchidism operation.

首先，我们通过将成年小鼠的睾丸推入腹腔，然后缝合单侧腹股沟管的方式，建立了体内实验隐睾诱导生精细胞凋亡的模型。

The length of section of unsaturated heat absorption of entrance of coolant. These offer evidence to optimising the U-shaped tube steam generator by distributing different

本文对换热过程的分析和结果较好地反映了单根换热管的换热情况，具有较强的参考应用价值。

Due to the cooling-water tube diameter of the generator is too small, the velocity of cooling-water is also too low, if we only use the travelling period difference of one emmission and reception, the propagation time will be too small to test. Then, we select ultrasonic circulation method as our concrete plan.

由于发电机冷却水引水管的管径小，冷却水的水流速度低，利用单次发射和接收的时间差检测时，传播时间差极其微小，故作者首次提出利用声循环法来检测大型汽轮发电机定子线棒冷却水流速。

There have been a lot of debates on the representative thickness for single-walled carbon nanotubes in the field of nano science.

为了未来元件的应用，单壁奈米碳管的临场成长与直径控制俨然已成为目前研究团队争相研究的目标。

In this thesis, we study the field-emission properties of individual CNTs systematically inside transmission electron microscope using the sample holder integrated with a scanning tunneling microscope.

本文在透射电子显微镜中，利用装有微型扫描隧道显微镜的样品杆对单根碳管的场发射性质做了较为系统的研究。

In order to further predict the durability of the TS-1 catalyst in the severe condition of calcination regeneration, a catalytic deactivation method was employed to facilitate the obtaining of deactivated catalyst from the regenerated sample, and thus the conduct of repetitious regenerations.

研究了负载成&蛋壳型&的TS-1催化剂在丙烯环氧化的单管放大试验装置上连续运转1 200 h失活后的焙烧法再生条件，并结合催速失活，对该催化剂进行了多次焙烧再生研究。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.
