速度计

The nerve axon regeneration length was measured 2 weeks after operation. The effects of peripheral nerve regeneration were evaluated by neural electrophysiology, the recovery rate of triceps surae muscular tension and weight and histological assessment 16 weeks after operation. Results All the animals survived till the end of experiment.

术后行大体观察；术后2 周测量神经轴突生长距离；术后16 周行电生理检测，计算术侧坐骨神经运动传导速度恢复率、术侧小腿三头肌收缩力恢复率及湿重恢复率，并行移植神经吻合中段HE 和半薄切片甲苯胺蓝染色观察。

The resulting speed-up comes from the reduction of the input impedance of the picoammeter due to negative feedback.

速度提高的原因是由于负反馈的作用使皮安计的输入阻抗降低。

Through the project, domestic GPS receiver/chip manufacturers have been surveyed, GPS signal simulations for coverage, signal quality, tracking loop, and positioning accuracy have been performed, a GPS receiver prototype has been implemented to overcome limitations due to high altitude, high speed, rapid Doppler variations, and vehicle motions, performance tests with other receivers have been conducted, and, finally, a specification for the development domestic spaceborne GPS receiver has been recommended.

本计画之主要成果包括完成国内相关厂商之资料收集、访查、与分析建议，完成太空级GPS接收机之模拟分析包括讯号观测、讯号品质、追踪回路、定位计算等，完成GPS接收机工程雏形系统之建立并针对高度/速度限制、都卜勒变化、快速撷取、与轨道计算进行韧体发展，及进行GPS接收机工程雏形系统与现有GPS接收机之功能与性能测试，及完成国产太空级GPS接收机之规格建议。
