Preface I am pleased to contribute an article to GSIS to commemorate the great achievements of *** Konecny on the occasion of the celebration of his 90th birthday.I was lucky to work closely with Gottfried as an ISPRS Council member for the first time in 1984 in Rio de Janeiro,Brazil,when I was elected as Congress Director of the Kyoto ISPRS Congress to be held in *** was elected as ISPRS President for 1984~*** the first Council meeting under the President Gottfried,he said to all Council members“as we are like a family,I request that we address each other by our first names”.If he had not said this,I might have called him Professor Konecny,according to Japanese custom.

Prediction of earthquakes using GPS remains an unsolved but important ***-signals in terms of changes in triangular networks of GPS Stations were examined for many large earthquakes in Japan and in other Asian regions.I discovered that the occurrence and location of an earthquake can be predicted with pre-signals found in GPS data ***,more research is required to predict how many days after the pre-signals an earthquake will occur.

The ambiguity resolution in the field of GPS is investigated in detail. A new algorithm to resolve the ambiguity is proposed. The algorithm first obtains the floating resolution of the ambiguity aided with triple difference measurement. Decorrelation of searching space is done by reducing the ambiguity covariance matrix＇s dimension to overcome the possible sick factorization of the matrix brought by Z-transformation. In simulation, the proposed algorithm is compared with least-squares ambiguity decorrelation adjustment （LAMBDA）. The result shows that the proposed algorithm is better than LAMBDA because of lesser resolving time, which approximately reduces 20% resolving time. Thus, the proposed algorithm adapts to the high dynamic real-time applications.

When the cycle slips take place in the attitude determination of a moving platform, the precision of the attitude will be impaired badly. A method of cycle slip detection and correction is proposed, which is suitable to the dynamic measurement using GPS carrier phase： the cycle slips detection is first achieved by triple difference observables, then the cycle slips correction is performed with baseline length constraint. The simulation results show that the proposed method is effective to the dynamic cycle slips problem.

以废革屑作为载体,通过戊二醛交联剂将壳聚糖嫁接于革屑上,制备胶原纤维基吸附材料,研究了其对酸性红A-2BF的吸附性能。分析了染料废水的pH、吸附剂用量、染料初始浓度、吸附时间对吸附性能的影响,对该吸附过程建立了适当的模型,描述了其吸附行为,对吸附机理进行了探究,用红外光谱表征了改性前后废革屑的结构。结果表明,在废液初始浓度为100mg/L,pH=4.0,吸附剂添加量为0.05g/100mL条件下吸附2.0h,吸附剂对溶液中染料的吸附率和吸附容量分别达到96.7%和188.2mg/g。该吸附过程符合拟一级动力学和Freundlich等温吸附模型,且为自发的吸热过。FT-IR分析表明,壳聚糖成功接枝到性废铬革屑,可为吸附染料提供吸附位点。
