气体的

Boyle's law is a law about gases. It states that if you increase the pressure on a gas, its volume decreases. This is like if you were to squeeze a balloon, the pressure of the air inside the balloon increases while the volume of the air decreases.

波以耳定律是关於气体的定律，该定律说明若增加气体的压力，气体的体积就会变小，这就像你若挤压一个气球，气球内空气的压力增加，体积却变小。

Boyle's law that the density of a gas is proportional to its pressure and Charles' law that the volume is proportional to the temperature, would be exact if gas molecules were points which had no volume and did not attract one another.

假如 气体没有量且彼此不相互吸引的话，玻意耳关于气体密度与压力成正比的定律以及查尔斯关于气体的量与温度成正比的定律就是正确的。

Following are summary of our works:(1)The powders of LaCr_(0.9)Co_(0.1)O_3, LaCr_(0.9)Fe_(0.1)O_3, LaCr_(0.9)Ni_(0.1)O_3, LaCr_(0.95)Sn_(0.05)O_3 and LaCr_(1-x)Ti_xO_3(x=0.0-0.3) were single perovskite phase with orthorhombic structure. The gas-sensing properties of their thick film sensors were tested in the acetone, ethanol, normal propyl alcohol, carbinol and formaldehyde organic gases. The sensitivity of the sensors can not be enhanced effectively by doping Co、Fe、Ni、Sn elements in B-site of LaCrO_3. Ti dopant with proper concentration can greatly improve the gas-sensing properties, which make the sensor display higher sensitivity and quicker response-recovery characteristics.
