是年的7月份，香港嘉道理农场暨植物园的李国诚、陈辈乐先生等一行四人，在保护区内的大丘田河流域进行了为期四天的海南鳽调查，其后，保护区的科研人员对海南鳽进行不定期的观察，间或有海南鳽疑似个体发现。

Adsorption and reaction of H〓 and nitrobenzene on the catalyst had been studied by FT-IR method.

除了成本较高外，传统的用于混合碳四馏分加氢的贵金属催化剂的选择性也很难提高，本文研究了Cu-Co-Ce／Al〓O〓催化剂的混合碳四馏分加氢除炔性能，这在国内还没人涉足，国外有关研究也较少。

The motor consists of a cluster of four YF-2 engines which use storable liquids, Unsymmetrical Dimethyl Hydrazine fuel and AK-27 oxidiser (nitric acid with 27% nitrogen tetroxide), and provide a total thrust of 96 tonnes.

发动机由四台集群YF-2发动机组成，使用耐储存液体不对称二甲肼燃料和AK-27液氧（硝酸和27%氮四氧化物），而且提供96吨的一个总推力。

The role of nonagricultural sector and the urban informal sector on absorbing rural labour is emphasized.

提出了农村劳动力在四部门间转移的构想，将人口迁移模型扩展成为四部门迁移模型，丰富和发展了劳动力转移的两部门学说。

Tetraploid organisms may arise by the fusion of two diploid gametes that have resulted from the nondisjunction of chromosomes at meiosis, or by nondisjunction of the chromoosomes during the mitotic division of a zygote.

四倍体的产生可能是由于两个二倍体配子发生融合，这种二倍体配子又是在减数分裂中染色体不发生分离而形成。四倍体也可能因为受精卵进行有丝分裂时染色单体未发生分离而形成。

In the first part, the thesis firstly constructs the production possibility sets deduced from constant, nonincreasing, nondecreasing and nondetermined returns to scale. Based on the above point, the thesis systematically deduces the models of DEA which evaluate production efficiency for exogenously fixed inputs and the models of ADEA (Allocative Data Envelopement Analysis) which evaluate cost, revenue, profit efficiencies and allocation efficiency in production possibility sets, and then discusses the solution properties of these mathematics models.

在第一部分中，首先以生产规模收益率不变、非增、非减和不确定四种情形下的生产可能集的构成为出发点，系统地归纳出在这四种生产可能集上评价具有固定不变输入或输出生产有效性的DEA模型及其相应情形下评价生产成本、收入、利润和生产配置有效性的ADEA模型，并讨论了这些数学规划模型解的性质。
