In this paper the mathematical models and methods for GPS single-point positioning are studied systematically on the theory.All kinds of error correction formulas are studied,such as ironsphere correction,troposphere correction,relativistic effect correction,earth rotation correction ,earth tides correction ,satellites antenna phase center offset correction. GPS single-point positioning programs is coded with pseudoranges and broadcast ephemerides,phases and broadcast ephemerides,and phases and precise ephemerides.And a great amount of computation has been done using the data collected .The results are computed with the 24 hour pseudoranges observation data before and after the canceling of the SA.

本文从理论上系统地研究了GPS单点定位的数学模型和方法，研究了各项误差改正公式，例如电离层改正、对流层改正、相对论周期部分改正、地球旋转改正、地球固体潮改正、卫星天线相位中心偏差改正；编写了伪距与广播星历、相位和广播星历及相位和精密星历的定位程序，并使用有关数据进行了大量的计算工作。

It can realize multiple analog single collection, multiple control single output .It can realize the communication between local equipment and epigynous machine by 485 bus.

它能实现多路模拟量输入，多路模拟量输出，PWM控制信号输出，通过485总线实现控制器与上位机的实时通信。

We produced two groups of pollinating wasps, either carrying pollen or not, and introduced one or two foundress wasps from each group into single figs. Figs entered by no wasps aborted rapidly, but almost all figs entered by wasps completed their development normally, except a few entered by a single pollen-free wasp.

结果发现：没有传粉榕小蜂进入的隐头花序果会很快终止发育并脱落；而在放了传粉榕小蜂的隐头花序果里，除少数几个放一只不带粉的外，隐头花序果基本都能完成其生活史。

As single website grow more enormous and web hyperlink structure became more complicate,it is very hard for those traditional web analysis mechanism — based upon single web page or pure hyperlink structure analysis.— to functionate satisfactorily.

随着单个web站点的日益庞大，web超链结构的日趋复杂，传统的建立在单个网页和单纯超链结构上的web模型已很难适应基于各种不同应用需求的web分析。

Recent data have provided clear insights into some aspects of self-recognition and rejection in the SI response of three types,the single-locus sporophytic and two distinct forms of single-locus gametophytic SI.

高等植物在长期的进化过程中，通过雌蕊识别并拒绝遗传上相近的花粉，防止近亲繁殖、保持遗传多样性，该机制被称为植物自交不亲和性。

ConclusionsUsing methods of narrowing genioplasty combined with Medpor implantation can treat wideness chin and retrogenia in one step. This method resolve the defaults of single horizontal osteotomy of the chin or single chin augmentation.
