IGMs are a kind of experimentally new-identified optical mode, standing with apparent potential in design and application. However, the mathematical expression of IGMs under Elliptic Cylindrical coordinates, preventing us from understanding IGMs instinctively, stands a formidable challenge in application. The pure mathematical expressions of IGMs are composed by a great deal of calculation, which also bids us no help in common use. I am, therefore, prompted to build an easier mathematical approach in this study.

Ince- Gaussian modes为在实验中可见的一种崭新型态的光学模态，对於我们在应用和设计上的实现，拥有许多潜力；然而，由於IGMs是在椭圆圆柱座标系下的数学来表示，造成了我们无法直觉的去了解，也成了我们在使用上的一大考验； IGMs的不易亲近，也让我们无从进一步去了解其物理特性，若纯粹以数学出发，又包含了庞大的运算，无法达到普遍的运用，是故我希望能在这篇论文使用简单的数学描述来达成对IGMs较平易近人的理解。

In automobile electrical check process,frequently can meet exchanges the situation which the new fuse blows a fuse immediately,moreover these breakdowns processing and the inspection quite are generally complex,The automobile services and drives the personnel frequently to be unable to inspect,The partial personnel even use replace a larger capacity fuse to replace,Has created a bigger harm,Serious also can create the fire equipollent major accident,This article from inserts the fuse is the fuse principle analysis obtains,Key introduction overhaul method and method,Thus is faster accurately looks up the breakdown reason and the spot.

在汽车电路检查过程中，经常会遇到换上新的保险丝立即熔断的情况，而此类故障的处理与检查往往比较复杂，汽车维修与驾驶人员常常无从入手，有的甚至采用更换更大容量的保险丝代替，造成了更大的电器损害，严重的还会造成火灾等重大事故。本文从插保险丝即熔断的原理分析入手，重点介绍检修的方法和手段，以便更快速更准确地查到故障原因和部位。

Teachers" and students" wrong teaching method -- force-feed type teaching and study. Students creativity is low, lacks critical spirit to the knowledge, can not innovation new knowledge. The rank system relations between teacher and student, students are in a passive position.

它造成师生的错误教材观；师生的错误的教学方法——填鸭式的教与学；学生的创造力低下，无从达到知识的创新；师生之间的等级制关系，学生处于被动的地位。

Thus, a principal-agent relationship between government and foresters was established.

然而，林农拥有生态公益林的信息量较政府占优，政府对林农在自然灾害突发事件前后的防范与修复工作无从得知，于是就形成了政府与林农在不对称信息下的委托－代理关系。
