The system can be used alone or be integrated into other GIS systems to enhance their map projection function. map projection ; map projective transformation ; analytical ordinal transformation ; analytical athwart transformation

在GIS应用系统中往往需要管理多种不同地图的地理数据，这些不同投影的数据在进行地理空间分析或信息复合时需要坐标同化，需要将不同投影的坐标统一到同一个坐标空间中，随着G

We have had the extensive studies on theα-acetyl-α-carbamoyl ketene--acetals and its further applications, for example, their adols condensations with aldehydes giveα-alkenoyl-α-carbamoyl ketene--acetals which can be utilized as the 1,5-bielectronic five-carbon components to react with various binucleophlilic species in a [5+1] annulation.

我们小组在以前的工作中对α-乙酰基-α-胺甲酰基二硫缩烯酮在合成中的应用进行了深入的研究，如与醛缩合生成α-烯酰基-α-胺甲酰基二硫缩烯酮，将其作为1，5-双亲电五碳合成子的[5+1]成环策略等。

In addition, the surface quality of the sample in argon is better than that in air and the deformation is easier.

在Ar气中的变形比在空气中的变形更加容易进行。

Athletics injuries would attar us frequently when we do physical exercise. Investigation the injury condition of students in PE Department in our university by the ways of questionnaire interviewing the data, statistics.

摘 要：在体育运动中，经常会发生运动损伤，通过问卷调查法，访谈法，数据统计法对我校在校体育系学生在体育运动中受伤情况进行调查。

And the general thoughts in which we can deal with the nonlinear integro-differential equations in Banach space.

全文共分为三章，在第一章中，我们对具有凹凸性的非线性算子的研究现状及我们在本文中将要做的工作进行了阐述；同时给出了我们处理本文所讨论的非线性积分-微分方程的总体思路。

Generally, the Fresenl lens is used for collimation and its structure is planeconvex, but the analysis and comparison of the biconvex and the plane-convex Fresenl lenses with P-W method show that the biconvex Fresenl lens is better because of its specific imaging requirement. The two kinds of the Fresenl lenses were modeled in ZEMAX to validate the conclusion.

从应用角度看，菲涅尔透镜设计属于准直系统，一般采用平面结构，但由于其成像要求的特殊性，通过运用P-W方法进行分析和比较，结果表明：曲面的设计较之于平面更具优势，并在ZEMAX中分别对2种菲涅尔透镜进行建模，验证了结果的正确性。

On the other hand, in order to contact to practical application and combine the actual experimental condition, we can make some elementary research on the application of boron nitride which has been synthesized.

将合成的纳米氮化硼材料进行表面改性，改善纳米粉体表面的润湿性，增强了其在介质中的界面相容性，使氮化硼纳米粒子容易在有机化合物中分散，提高了氮化硼纳米粉体的应用性能。

During the process of branching optical cable, the duct is opened for a piece of 10cm first, then cut the guided tube for branching, and connect the guided tube with new one, finally install Y-connector, through which the micro cable can be installed by air-blowing in.

在进行光缆分歧时，首先用切管刀将母管切开一段约10cm的口子，然后剪断要进行分歧的那根子管，并用连接头将剪断的子管和支线的子管连接，最后安装Y型连接器。完成上述工作后，即可向子管中吹入光缆。
