摘要： A trace detector is disclosed. The trace detector comprises: a desorption chamber defining a desorption region, and the desorption chamber has a housing. The housing has a sample feeding port for introducing a substance to be detected into the desorption chamber and a gas discharge port for discharging gas entraining the sample from the desorption chamber. A controller is used for controlling the trace detector in such a manner that the sample feeding port and the gas discharge port are in fluid communication with the desorption chamber during pre-concentration process of the trace detector, thereby continuously feeding and collecting the sample. With the above manner, data collecting, processing and analyzing processes may be performed by the trace detector throughout the sample feeding process and the gas pre-concentrating process. The trace detector has an excellent detecting period of time whether the substance to be detected in the gas is in a high concentration state or a low concentration state, and the trace detector can perform continuous sampling for a long time, thereby improving a ratio of the amount of trapped substance to the amount of the substance entrained in the gas to be detected and the amount of the cumulated trapped substance, decreasing the probability of failing to detect the substance, and increasing detection sensitivity. In addition, the detection efficiency of the detector is increased during the gas pre-concentration process.

摘要： A precision tilting platform used for static calibration of seismometers is composed of a base, a worktable, a rotary part, a driving part, a measuring part and supporting frames. The rotary part is composed of a shaft, a driving arm, a rotary table and a clump weight. The shaft is fixed on the left and right supporting frames. The driving part and clump weight are assembled beside the two sides of the driving arm. The driving part is composed of a linear motor, a sliding table, a pair of linear guides and sliders and a grating scale. The readhead of the grating scale is fixed with the base and sends out the signal of zero position when the worktable is horizontal. The sliding table is closely contacted to the driving arm. When the linear motor is moving forward, the rotary part is pushed by the sliding table and rotates toward the positive direction. When the linear motor is moving backward, the sliding table is pulled backward and the rotary part rotates toward the negative direction because of the gravity of the clump weight. The measuring part is composed of a laser interferometer and a reflector that reflects the laser beam back to the laser interferometer to obtain the tilting angle of the worktable, on which the reflector is mounted. The present invention has the advantage of high positioning accuracy, high transmission efficiency and wide application.
