LED or photo aging components: the core of IC optical mouse has a constant internal integrated circuit, the LED constant current of about 50mA, the general use of the mouse high-grade intermittent sampling technique, sent intermittent conduction current is the (sampling frequency of about 5KHz), can be in the same power under the premise of testing to enhance the power LED, the high detection sensitivity.

1发光管或光敏元件老化：光电鼠标的核心IC内部集成有一个恒流电路，将发光管的工作电流恒定在约50mA，高档鼠标一般采用间歇采样技术，送出的电流是间歇导通的(采样频率约5KHz)，可以在同样功耗的前提下提高检测时发光管的功率，故检测灵敏度高。

Amur tigers had a copulatory pattem with no lock,thrusting, multiple intromission,and single ejaculation,which belonged to copulatory pattern No.11 in Dewsbury\'s copulatory-patterned system.5 The behaviors that accounted for most of the total time budget during the parturition period were grooming,lying and licking kittens,26.90%,26.23%and 23.83%,respectively.

东北虎的交配模式属于Dewsbury分类系统中的第11种，即无锁结、有抽动、单次插入、多次射精。5在分娩过程中，雌虎的梳理、卧息和舔仔行为时间最长，分别为26.90%、26.23%和23.83%；梳理、努责和舔仔行为发生频率较高，分别是37.95%、18.75%和12.50%。6在育幼过程中，雌虎室外期与室内期哺乳和亲仔行为的时间差异极显著(P＜0.01)，离开行为的时间差异显著(P＜0.05)。

The are obvious biases in the both codon and amino acid usage in Lepidoptera species mitochondrial PCGs.NNU and NNA are the most frequently used codons.

鳞翅目昆虫的线粒体基因组中蛋白编码基因密码子的使用和氨基酸使用都有极强的偏向性，其中NNU和NNA密码子的使用频率相当的高。

At the condition of high spacial frequency, the principle and methods of image blind deconvolution has been studied, and the method of regularization image blind deconvolution based total variation has been used in the restoration problem of the 1-D bar code signals. The problem of blurring and interaction of bar signals under convolution with the SPF was solved with the method.

This dissertation introduces the whole scheme、the hardware electro circuit design and software design, the result of experiment on salinometer is preferred at the end of the dissertation. Salinometer is base on SOPC technology, and use digital technology to design circuit: the excitation source for balance bridge is generated by digital method, its shape、amplitude and frequency can be control by digital signal, the standard branch of bridge is composed of three digital-analog-conversion, and uses the method of successive approximation to regulate the balance of bridge.

盐度计以SOPC技术为基础，通过数字化方式设计测量电路：电桥的激励源由数字化方式产生，激励源的波形、幅值和频率等可由数字量控制；平衡电桥标准支路由3个数模转换器组合实现，测量时以逐次逼近的方式调整电桥的平衡度；检测电桥平衡度的高灵敏度数字检流计同样以数字化方式设计，它的增益由程序控制，将电桥的输出电压数字化，以软件判断电桥平衡度。

The modulation of sound properties over a wide range of time scales is one of the most obvious characters of Oscine passerine\'s vocal, whose song contains many different kinds of syllables that consist of many more multiple song phrases. In oscine passerine, ipsilateral projections of RA to NXIIts innervates the ipsilateral syringeal muscles exactly, and thus they have strong ability of vocal control with variable tones, high frequency and higher lever of quality.

鸣禽鸣啭的最大特点之一便是其单次鸣唱时间长，鸣唱所包含的音节数量和音节种类繁多，因而由这些音节所组成的句型结构也是复杂多样富于变化，且由于NXIIts严格的侧别控制(每一侧核团只支配同侧鸣肌)，使其具有更强的控声能力，其鸣声音调变化幅度大，频率高，品质因数大，音色好，因而其鸣声也悦耳动听。

10The simulations of an empirical model indicated that, when the outcrossing rate was no more than 1%, a 2 m buffer area with pollen receiver individuals between pollen donor and receiver was sufficient to minimize the frequencies of gene flow to .9%.

对栽培稻到其野生近缘种的基因漂移进行模拟的结果表明，栽培稻到野生稻的基因漂移频率较高并且可能会对邻近的较大范围内的野生近缘种群体造成影响。

The model simulations indicated that, when the outcrossing rate was no more than 1%, a 5 m buffer area with pollen receiver individuals between pollen donors and receivers was sufficient to minimize the frequencies of gene flow to .9%.

然而，对栽培水稻到其野生近缘种的基因漂移进行模拟的结果表明，栽培水稻到野生稻的基因漂移频率较高并且可能会对邻近的较大范围内的野生近缘种群体造成影响。

This paper presents a review of studies of interference absorbing materials,which come in three basic types:normal interference absorber,Jauman absorber and FSS absorber. And we particularize the structures,applications and methods of analysis and design of each of these types. Results show that the FSS absorber provides a better absorption ability and is more practicable,and that active multi-layer FSS absorber represents a new direction of interference absorbing material research.
