摘要： A Z-axis capacitive accelerometer includes a substrate, a capacitance sensing plate, a proof mass and at least one pair of spring beams. The capacitance sensing plate includes two symmetrical sense areas to create differential capacitive measurement. A decoupling structure separates the proof mass and the capacitance sensing plate and their rotational motions from each other. In the proposed Z axis capacitive accelerometer, the distance of the capacitance sensing plate relative to its rotation axis is considerably increased, thereby effectively enhancing the sensitivity when measuring the Z-axis acceleration.

摘要： A plasma oil-free ignition system in oxygen enriched environment comprises a plasma generator and a burner. The plasma oil-free ignition system comprises a sleeve group coaxially arranged with the burner, and the sleeve group comprises multiple coaxially sleeved sleeves. Annular spaces are formed between adjacent sleeves and between the sleeves and the burner. Oxygen ducts are arranged on the sleeves, and oxygen ducts are arranged on the burner. Plasmas jetted by the plasma generators form a local high temperature zone filled with high temperature plasma and pulverized coal air flow. A certain amount of oxygen is fed to the burner through the oxygen duct therein to form local oxygen enriched zones in the annular spaces and the subsequent adjacent spaces through which air flows, thus realizing oxygen enriched combustion of volatile matters or coke or mixture thereof, and combustion the pulverized coal air flow more intensely to release more heat so as to ignite the primary air pulverized coal air flow quickly and burn the pulverized coal air flow stably. The invention has simple structure, is applicable to different coal types, especially applicable to the plasma oil-free ignition system in oxygen enriched environment of coal types with low volatile matters.
