The paper analyses the meaning, feature, and the function of land trust protection from the trust basic principles.

1论文首先将我国现有的土地管理模式归纳为以耕地保护为核心的政策保护，并利用系统理论、委托代理理论和公共管理理论等从几个方面分析了这种模式的弊端和不足，指出了现有的以耕地保护为核心的政策保护模式需要社会化、多元化土地保护机制的有效配合。

This paper applies the encryption to the sensor of taximeters.It provides encrypt ion models and system structure model of encrypting sensor of taximeters based on analyzing bugs of sensor of taximeters now,then designs hardware of Encrypting machine,decoding machine and machine that writes into secret code using PIC12C508A,PIC12CE518A and INTER8031.Secret code sensors after encrypting raise accuracy and security of taxi charges greatly,and solve existing difficult problems of reliability and management i...

该文把加密技术用于出租车计价传感器中，在分析现有出租车传感器漏洞的基础上，提出了出租车加密传感器的加密模型和系统结构模型，采用PIC12C508A、PIC12CE518A和INTER8031单片机完成了密码传感器系统中加密器、解密器和密码写入器软硬件系统设计，加密后的密码传感器大大提高了出租车计价器计费的准确性和安全性，解决了现有出租车计价器可靠性不高和难以实现统一管理的难题。

The equipment unit model can be made up of several post model, and the different equipment unit model can be made up of now-existing post model or inherited model. It can improve the efficiency of exploiting new equipment model and avoid working again.

装备实体模型可以由几个岗位模型组合成，不同的装备实体模型可以利用现有岗位模型或继承现有模型组合成，这样可以大大提高开发新装备模型的效率，同时也避免了重复开发。

In contrast to the existing recoding system, this system has simple structure with lower cost, and the function of satellite simulator makes up the defect of existing recording system.

与现有记录系统相比，该系统具有结构简单、造价较低的优点，同时其卫星模拟源的功能也弥补了现有记录系统的不足。

From these original, rough calculations, designers can figure out how large of a powder charge is needed, based on existing powder, and then complex mathematical calculations can determine how thick the barrel has to be to withstand this charge, and how long the barrel must be so that the powder is done burning just as the shell exits the barrel.

对这些现有的大炮进行粗略的计算，设计者们可以算出，基于现有的发射药，需要多少的装药量。然后复杂精确的计算可以测定火炮身管需要怎样的厚度来承受这些装药的威力，需要怎样的长度以便使装药在炮弹出镗的时候刚好燃尽。

SECTION 9.4 EXISTING CONDITIONAL USE PERMITS There are certain existing conditional use permits in the Township which were granted and effective as Special Use Permits under the Clinton County Rural Zoning Ordinance prior to the adoption of this Ordinance.

第9.4节使用许可证现有的条件有某些现有的乡利用这些条件，并根据批准的克林顿县农村分区条例特殊用途许可证之前生效本条例的通过许可证。

Firstly, the existing working process is analysed and the defects of it are indicated, new management working pattern is pointed out.

论文首先对现有的工作流程进行了分析，指出现有工作方式的弊端，提出了新的管理工作模式。

At large scale, the result of comparing of optimization structure of forest type with the present structure of forest type illustrates that the present economical forest area is larger while the mixed forest is smaller. So decreasing economical forest area and increasing mixed forest area should be the main measurements to optimize spatial patterns. At small scale, the evaluation of the landscape inner structure index illustrates that the forest structure and coverage is smaller, which should be regulated and so the uneven-aged, multi-layered and mixed forest should be the object of the forest structure design.

大尺度上根据植被类型优化结构和现有植被类型结构数据的对比分析可知，现有经济林面积则过大，混交林面积较小，因此主要是减少经济林面积，改造针叶和阔叶纯林为混交林，从而增加混交林面积，以达到最优植被类型结构时的空间配置；在小尺度上通过对景观内部结构指数的计算分析可知，该区林分结构和郁闭度分指数值较小，应予以着力调整；由研究结果可知，异龄、多层次、混交的水源保护功能最好，因此稳定的林分结构设计目标就是尽量使林分形成异龄、多层次、混交林。
