不固定的

The fundamental nature of modern urban community relations is the tool rather than emotion. The border of community is not a fixed geographical border but the bounder of the collective action.

现代城市社区的基本性质是工具性的而非情感性的，社区的边界也不是固定的地域边界而是变化着的集体行动的边界。

He entered his novitiate to the true wilderness with Sam beside him as he had begun his apprenticeship in miniature to manhood after the rabbits and such with Sam beside him, the two of them wrapped in the damp, warm, negro-rank quilt while the wilderness closed behind his entrance as it had opened momentarily to accept him, opening before his advancement as it closed behind his progress, no fixed path the wagon followed but a channel nonexistent ten years ahead of it and ceasing to exist ten yards after it had passed, the wagon progressing not by its own volition but by attrition of their intact yet fluid circumambience, drowsing, earless, almost lightless.44

孩子就这样进入了熟悉真正的荒野生活的见习阶段，有山姆在他身边，正如他小时候追捕兔子这类小动物度过雏形的见习时期，山姆也陪伴在他身边，这时两人裹在湿漉漉、暖烘烘、散发出黑人臭味的被子里，方才暂时对他开放来接纳他的荒野在他身后合拢了，森林在他前进之前开放，在他前进之后关闭，大车也没有固定的路可走，只有一条仅仅看得清前面十码路的通道，大车走过十码后，这段路也就湮没，这大车并没有按自己的意志往前行进，而是由人和大车所造成的纯净的气流浮托着在往前滚动，大车在打瞌睡，听不见一点声音，也几乎见不到一点光线。45

Objective To study the power spectrum density of blood flow ultrasonic Doppler signal using wavelet analysis. Method Doppler signal of blood flow in human common carotid artery was studied with wavelet scalogram analysis, an affine smoothing Wigner Ville transform with a constant "Q" character. Result Wavelet scalogram of blood flow ultrasonic signal had a higher distinguishability than STFT spectrogram in the low frequency portion, but had poorer decussation terms than spectrogram.

对于平稳信号的处理工具仍然是Fourier变换，但是，在实际应用中的绝大多数信号是非平稳的，现在看来处理非平稳信号的主要工具将是小波变换，这主要是因为传统的Fourier变换分析信号时，时间和频率分辨率精度是固定不变的，而利用小波变换分析信号，在信号高频段时间分辨率精度也较高，在信号低频段频率分辨率精度较高，这很符合非平稳信号的特点。

The figure of the Bodhisattva is heavy and majestic. The Samantabhadra of Pl.12 is altogether more approachable, partly as a result of its softer outlines, partly because of its more restricted use of colour and of line that is more descriptive of the underlying form than assertive of a prescribed pattern.

而图12的普贤菩萨像却容易亲近的多，一部分是因为它的轮廓不那麽鲜明，一部分是由於它使用了更少的色彩和线条，比僵化的规定形式更加灵活，由於没有使用固定的模式，使他的身体更清楚地表现出来。

And this research also study the issue that orders quantity is different from reserved capacity quantity and propose a management mechanism. Finally, by the actual foundry industry example to proof the mechanism is practicable.

本研究提出的改良方法，是根据客户所获得的预留产能，将其均摊至各周作为订单允诺的基础，也就是说每个客户每周的可允诺量是固定的，而不会受到订单早来或晚来的影响，以改善实务上先进先出法的缺点。

The "tile"is a power unit but , is voltage and voltaic product, voltage is to maintain fundamental note type computer operation operating voltage , electric current is the situation looking at operation , power consumption having diversity but, power consumption is higher if opening DVD and the trumpet , pure await the opportune moment power consumption is lower , the entirety comes say therefore the machine power consumption is not fixed, but is status have height to have consuming an electricity low.

而"瓦"为功率单位，为电压与电流的乘积，电压为维持笔记型电脑操作的基本工作电压，电流则视操作的状况，而有不同的耗电量，如开启DVD及喇叭耗电量较高，纯待机耗电量较低，所以整体来说，机器的耗电量不是固定的，而是有高有低的耗电状况。

In addition to the signal strength is probabilistic vibration, and it follows Gaussian normal distribution in signal space.

此外，在讯号空间的观点来看，固定一对传送端和接收端的距离，各种讯号强度出现的机率的是呈现Gaussian Normal Distribution，因此利用RSSI (Received Signal Strength Indicator)的测量距离的技术是不准确的。

Ecotourism — sustainable travel that is built around observing wild animals, not disturbing them — provides vital revenue for many local communities in wildlife-rich areas. And a steady stream of tourists can help convince people in biological hotspots like Madagascar or the Brazilian Pantanal that the local wildlife is worth more alive than extinct. For visitors, the prize is a firsthand study of the extinction crisis: you can't really understand what the world is at risk of losing, until you've come eye-to-eye with an indri lemur or a ploughshare tortoise.

生态旅游--可持续发展旅游，比如观看野生动物，但不打扰他们--为野生动物集中地区提供保护资金，固定的旅游团体的观光也会帮助当地居民比如马达加斯加和巴西潘纳尔更确信保护野生资源的观念，对于游客来说最大的收获就是亲眼目睹了濒临灭绝的危机，只有你亲眼看到一只大狐猴或一只乌龟的照片你才知道世界面临着每时每刻都在消失一些物种的危机。

The experiment shows that:(1) In certain light intensity and electric field ranges (145～305V/cm) the material Si∶ with a resistivity of 1E4Ω·cm exhibits a current oscillation phenomenon at liquid nitrogen temperature;(2) At a certain electric field,the waveform of the current oscillation is stable and does not change with time;(3) The dependence relation between the oscillation frequency and light-intensity can be expressed by f=f0(L/L0)α where L0 is the minimum light-intensity needed to stimulate oscillation,f0 is the frequency under L0,L is the intensity of the light,and α is a coefficient that increase with electric field;(4) The modulating coefficient K K=(Imax-Imin/Imax decreases as the light increases;(5) The maximum value of the oscillation Imax decreases with the increase of the light-intensity while the minimum value of oscillation Imin increases slowly.

结果表明：在一定光照和电场范围内（276～305V/cm ，电阻率为10.4Ω·cm的材料在液氮温度下显示出电流振荡特性；在一定的电场下，电流振荡波形是固定的，不随时间变化；振荡频率随光照强度的增大而线性增大；调制系数随着光强的增强而减弱；振荡的最大值随着光照强度增大而减小，最小值随着光强增大而缓慢增大。

Higher vocational education is a self-consistent vocational education system appropriate to the development of national economy AND productivity.

高职教育是自成体系的国民经济发展和生产力相适应的职业教育。有与出版物总发行业务相适应的设备和固定的经营场所，经营场所的营业面积不少于1000平方米
