The synthetic nourishment index method averages the trophic index of all parameters, and then evaluates the degree of the eutrophication. The total composition analysis nourishment evaluation colligates all kinds of representative parameters, and then evaluates the degree of the eutrophication. The grey system theory method evaluates the degree of the eutrophication through a series of calculations, such as constructing situation and situation matrix, confirming object degree, and so on.

总成分分析营养度评价法是通过对各单因子的分营养度进行算术平均，将水体营养状态连续分级；综合营养状态法是综合多项富营养化代表性指标，将其表示成指数，对水体营养状态连续乡级；灰色系统理论法是通过构造局势与局势矩阵、确定目标效果测度、多目标决策、确定最优局势等一系列系统分析计算，判断水体富营养化级别。

本文通过计算公式中字符的最小外接矩形，将字符依次分割开并记录其位置信息，然后进行归一化处理，利用本文设计的适合本文中字符识别的识别模块，即二层感知器神经网络识别模块，将归一化后的字符识别出来。

multi-channel correlators are widely used in traditional pseudo-random code cw radar,which makes the ranging system more complicated.this paper proposes a method of digitalizing the return signal directly and then convoluting the signals on dsp,which can replace multi-channel correlation in analog circuit.but the computation of convolution is too huge for the dsp to fulfill.to solve this problem,this paper analyzes five fast algorithms including fft,and then chooses one according to the characters of prc-cw radars.the digital method and fast algorithm have been verified by simulated signal and real signal.

一种提高空间伪码扩谱测距精度的实用。。。摘要：传统的伪码调相连续波雷达采用多路模拟相关电路实现对回波信号的相关接收，通过多路试探搜索各距离单元的目标，电路复杂。提出的数字化方案，对回波信号直接数字化，利用高速dsp实现数字卷积，可替代多路模拟相关电路。但是直接卷积的运算量过大，dsp无法承受。本文对此进行了研究，分析了包括fft在内的五种快速算法，结合prc-cw雷达的具体情况，确定了一种适于dsp实现的快速卷积算法。仿真和实测数据证实了数字化方案及快速算法的正确性。

如果澳洲或新西兰让他们靠码头没有扣押小船和递解国际性组织和锁澳大利亚违者，我们然后有一些严肃的问题作为这无法允许进行的国家，因为某人将被杀害，并且什么然后将发生？

Frankly speaking, firearms, explosives to me, I will save her, first and foremost position in which housing, using dynamite dynamited two or three gates, and then use of firearms and ammunition with a total of armed police to shoot the dog, and then save the the victim, as special forces in hostage rescue mode.

坦率讲，给我枪支炸药，我就会去救她们，首先定位在哪个房屋，用炸药炸开两、三道铁门，然后用枪支弹药跟共狗武装警察进行枪战，接著解救受害者，就像特种部队在解救人质模式。

But if what we have is a random OTP, enciphered by simple columnar transposition, and the message, first with the OTP applied, and then enciphered by Playfair, then it is not at all clear how we can apply techniques analogous to those used against these two ciphers in the double encryption case.

但是，如果我们有一个随机的OTP ，加密由简单的柱状换位，并邮件时，先与检察官办公室申请，然后由加密playfair ，那么，它现在还不很清楚，我们如何能够适用技术类似于那些用来对付这两个密码在双重加密的情况。

Good morning, on July 7Though still in bed, my thoughts go out to you, my Immortal Beloved, now and then joyfully, then sadly, waiting to learn whether or not fate will hear us - I can live only wholly with you or not at all - Yes, I am resolved to wander so long away from you until I can fly to your arms and say that I am really at home with you, and can send my soul enwrapped in you into the land of spirits - Yes, unhappily it must be so - You will be the more contained since you know my fidelity to you.

虽然还躺在床上，我的思绪却飞向了你，我的不朽的宠儿，我时刻在快乐又悲伤地等待着，不知命运否听到我们的呼唤-我只能完全地与你生活在一起，否则毋宁死-是的，我决定要远离你，直到我能飞入你的怀抱，说我真正与你在一起了，并把我的灵魂包裹进你的精神之地-是的，很不幸它必须如此-你是那个更满足的人，因为你知道我对你的忠诚。

Though still in bed, my thoughts go out to you, my Immortal Beloved, now and then joyfully, then sadly, waiting to learn whether or not fate will hear us - I can live only wholly with you or not at all - Yes, I am resolved to wander so long away from you until I can fly to your arms and say that I am really at home with you, and can send my soul enwrapped in you into the land of spirits - Yes, unhappily it must be so - You will be the more contained since you know my fidelity to you.

还在床上，我的思绪已经去了你那里。我永生的爱人，此时和彼时的，欢欣和悲伤的，等待着命运倾听我们的要求的--你。我只能完整地跟你在一起，不然完全不能存在。是的，我坦然地离开，只要我能够飞奔到你的怀里，可以告诉你，我只有跟你在一起才有了家的感觉。我的灵魂只有在你的包围环绕里才能到达精神的家园彼岸。是的，你一定是痛苦的。也许你了解我对你的忠诚之后，才能安宁。
