采用加入其他元素的方法使硅化铌改性可达到减少穿透硅化铌涂层微裂纹的生成和降低铌基材氧化速度的目的，但使用温度一般不超过1 300℃[1~3]。

But although the source of such foul space weather is known—it happens when giant flares on the surface of the sun pour out more protons and electrons than normal—the details depend on structures within the magnetosphere that are only now coming under scrutiny. Sometimes storms drift past the Earth with little impact. On other occasions they pummel the magnetosphere's crown to about half its normal distance from the Earth's surface.

曾有一段时间太阳表面巨大的火焰散发出比平常更多量的质子与电子，可尽管恶劣天气状况的原由已被人们所知，然而磁气圈内的结构的详细情况直到目前才得到人们的重视并受到详细审核。

And 0.4～0.6 respectively for the induction coil with round crosssection and rectangular cross-section; The magnetic flux density of coil made with round pipe was nonuniform, especially near the inner wall of coil turns that caused a fluctuation of electromagnetic pressure on the surface of liquid metal and had a bad effect for forming a sample with uniform cross-section and smooth surface; The system of screen and restraint magnetic field not only had an efficient effect on restraining the electromagnetic stirring and stablizing meniscus, also caused the conecial periphery of melt to be vertical; The position of top and S/L interface of melt had a direct effect on the meniscus shape. The meniscus profile varied from cone-shaped through column to cucurbituceous shape with the increase of top height or decrease of S/L interface.

对圆形截面、矩形截面感应圈来说D/H分别取0.7～1.1，0.4～0.6较为理想；对多匝感应圈来说，在匝间处存在漏磁，易引起熔体表面起伏不平，这种现象在用圆铜管绕制的感应圈中较为明显；屏蔽—抑流系统的加入可以消除电磁搅拌，使熔体稳定性增强，同时可使形态呈锥形的熔体侧面变得垂直成为理想形态；熔体上液面、固/液界面的选位直接影响成型形态，上液面升高，熔体形态经历锥形→柱形→葫芦形的转化，固/液界面下降则经历锥形→葫芦形的转变。

After remineralization, the surface structure of samples in Chinese nutgall group and Ag（ NH3 ）2F group became compacter and steadier, with presentation of small blotch and trabs; in NaF group, there was still laeune with trablike structure on the surface of the samples; in deionized group, the surface of samples was honeycomb appearance.

再矿化后，五倍子液和氟化氨银液组表面结构更加致密，均匀，呈小斑块，条索状；氟化钠液组表面也出现条索状结构，但仍有孔隙或腔隙存在；去离子水组表面出现蜂窝状结构。

Generally, electric-conductivity materials such as metal, conductive polymers, and graphite are coated on the outside surface of the capillary tip followed by the application of an external high voltage on the tip to provide a sufficient electric field to generate electrospray in seathless interface. Thus, the fabrication of the electric-conductivity material on the surface of fused-silica is one of the main issues when using sheathless interfaces.

一般来说通常需要将金属、导电高分子、或石墨等导电材料涂布於毛细管样品出口尖端，外加第二组电压於导电尖端以提供电喷洒时所需要的电场，但如何将导电材料稳定地涂布於矽氧材质的尖端表面一直是此界面探讨的主题之一。

Methane adsorbed on the Mn〓O〓-Na〓WO〓/SiO〓 catalyst can not be found, but it can be adsorbed on outgassed silica at 173K. Such adsorption is formed by interaction of the adsorbed methane with O〓〓 sites and hydroxyls on the surface. The appearance of the band at 2904cm〓 of the V〓 mode (sym. stretch.), which is an infrared forbidden vibration, implies that the Td symmetry of the methane molecule may be distorted somewhat on the surface of silica. The small frequency shift (30cm〓) of OH stretching indicates that only a weak hydrogen-bonding interaction between adsorbed methane and hydroxyls exists in the methane adsorption.

甲烷不能在Mn2O3-Na2WO4/SiO2催化剂上吸附但在l73K的温度条件下可吸附于SiO〓表面上，这种吸附是通过吸附甲烷与表面配位不饱和氧和表面羟基作用而形成的，红外禁阻的V〓振动模式显示出红外活性说明甲烷分子的Td对称性发生畸变，甲烷吸附后羟基位移只有30cm〓，吸附甲烷同表面羟基间的氢键作用很弱。
