在氰化过程中，Cu容易形成Cu2沉淀覆盖在矿物表面上，阻碍金的继续浸出。氰化刚开始，金的浸出速度快，18h后氰化浸出速度降低，26h后金的氰化浸出停止。

Mobile positioning system or dynamic table so that the laser head is cutting material in the system-driven subcapital high speed, laser head from the light source and cutting heads, light source produces a very short wavelength focused laser beam, laser beam through cutting heads, vertically focused the material being cut on the surface, heating and melting, evaporation is cutting material, resulting in the closure of Lancing, slotted openings formation pads.

移动定位系统妪动工作台或激光头，使得被切割材料在系统驱动头下高速运动，激光头由光源部分和切割头组成，光源部分产生波长很短的聚焦激光束，激光束通过切割头，垂直聚焦在被切割的材料表面上，加热、融化、蒸发被切割材料，形成切缝，闭合的切缝形成焊盘开孔。

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。

Moreover, some fragments were found to be adhibited on the surface of non-crystallized starch.

此外，在非晶淀粉的颗粒上均发现有少量碎片黏附在淀粉的表面上。

From the surface, the atmosphere is labelled the troposphere for the first 14km up, then the tropopause (4km height), then the stratosphere (about 32km height), then the mesosphere (40km), then the ionosphere (over 600km in height) and finally the exosphere (another 200km), which is the boundary of space.

从表面上看，气氛标签的第一个14公里的对流层上升，那么对流层顶（4公里高度），然后在平流层（约32公里高度），然后中间层（40公里），然后在电离层（高度600公里以上）和最后是散逸层（另200公里），这是空间的边界。
