The results of calibration of 4He in desorption system show that the correlation coefficient is more than 0.99 and the contribution of memory effect can be ignored. The contribution of ionized atom T(superscript +) for partial pressure of m/e=3 is very little and is determined according to I+≈0.01I(subscript T2)+, so the measurement of 3He can be done without interference of T(superscript +). The relationship between gases release rate and annealing temperature can be obtained after the data are smoothed and differentiated.

研究结果表明：四极质谱计标定解吸系统内4He的分压＜350 Pa时，其相关系数R＞0.99，且记忆效应的贡献极弱；离子态氚T对m/e=3组分分压的贡献可按I+≈0.01I(下标 T2)+确定，不干扰3He的测定；将气体解吸所得的积分数据经平滑并微分处理后可准确得到气体释放速率与退火温度的关系，即热解吸谱。

The network transmission part is based on TI's TMS320C6000 series DSP and the Network Development kit.The Ethernet interface between DSP and computer cluster has been implemented and the test on the performance of the interface has been made. Furthermore, the relationship between the number of hydrophone sensor heads and the network bandwidth has been analyzed which leads to the method of how to calculate the minium bandwith of network given the scale of the hydrophone array.

Experimental results show that this method is effective as it not only takes into account the preference relationship, but also improves noise immunity, and thus is more suitable for practical application.

实验结果表明，该方法不但考虑了系统属性值的序值关系，并且对数据噪声不敏感，因而更符合实际应用的要求。

In this paper, firstly, the new combined error model of cumulative geoid height influenced by three error sources including the inter-satellite range-rate of K-band ranging system, orbital position of GPS receiver and non-conservative force of accelerometer from GRACE satellites is established using the semi-analytical method. Secondly, the dependability of error models is demonstrated based on matching relationship among the accuracy indexes of key payloads. Finally, the accuracy of global gravitational field up to degree and order 120 is effectively and rapidly estimated from GRACE Level 1B measured observation errors of the year 2006 publicized by the Jet Propulsion Laboratory in the USA, and the cumulative geoid height error is 18.368 cm at degree 120, which preferably accords with the Earth's gravitational field model EIGEN-GRACE02S provided by the GeoForschungsZentrum Potsdam in Germany.
