More than 50 GaAs/GaAlAs High Power Single Quantum Well Semiconductor Lasers are aged. The threshold current decreases during the early aging (first 520 h) and the largest decrease is 57 mA. From the aging result of more than 1000 h at constant current, we find that output power increases during the early aging , and then decay slowly according to exponent law.

通过对50余只808nm的GaAs/GaAlAs高功率单量子阱远结半导体激光器的老化实验观测，在老化初期（前520h），阈值电流随老化时间的延长而下降，下降幅度高达57mA，从1000h多的恒流电老化结果可以看出，器件的输出光功率在老化初期有所上升，随后，表现出按指数规律缓慢下降的行为。

The objective of the thesis is to present newly developed AC driver and protection circuits for light emitting diode. The LED modules for each upper and low arm are with pulse-width modulation control in every half fundamental cycle. The indication and protection circuits act whenever short circuit and open circuit of LED module occur. Moreover, the current path is switched off when there is a short circuit of LED module.

目前一般白光发光二极体的驱动器，皆是使用直流电源驱动，本文利用发光二极体本身单向导通的特性，将发光二极体串接成桥式整流器的方式，只需控制流经中间路径的电流周期，就可达到调整发光二极体亮度之目的，并且增加发光二极体故障时的保护指示电路。

Constructed by standard binary classes support vector machine, present multiclass SVMs are usually very slow to be trained. When a large number of categories of data are to be classified, the training work could be very difficult. By extending the hypersphere one-class SVM to a hypersphere multiclass SVM, we build a fast training classifier HSOC-SVM. Its training speed is higher than that of the present multiclass classifiers, because each category data trains only one HSOC-SVM.

目前的多类分类器大多是经二分类器组合而成的，存在训练速度较慢的问题，在分类类别多的时候，会遇到很大困难，超球体多类支持向量机将超球体单类支持向量机扩展到多类问题，由于每类样本只参与一个超球体支持向量机的训练，因此，这是一种直接多类分类器，训练效率明显提高。

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。

METHODS: We reviewed the course of 28 eyes of 28 patients who underwent intravitreal injection of bevacizumab for treatment of CNV secondary to OHS.

我们回顾了28例患者的28只眼在玻璃体腔注射贝伐单抗治疗继发于眼组织胞浆菌病的脉络膜新生血管的病程。

As a singlet curved lens is impossible to correct all the five primary aberrations regardless it is made of PIMs or NIMs, the primaxy-aberration-free lens systems composed of two thin lenses or two thick lenses based on the use of NIMs are intentionally presented.

由于只靠单块曲面透镜是无法同时消除全部五种初级像差的，因而我们接着研究了由负折射率介质构造的能同时消除全部五种初级单色像差的双薄透镜组合系统和双厚透镜组合系统。

The album's solid-gold anthem, and first single, is "Coming Around Again", an utterly infectious folk-tinged number that promises to be as big a hit as last year's "No Worries".

这张专辑象本金制的赞美诗，而首只单曲&Coming Around Again&是一首绝对具有感染力的上口之作，它会象去年的&No Worries&一样成功。

Two more Avenue Blue projects were released by Mesa/Bluemoon -- Naked City in 1996 and Nightlife in 1997 -- but after that, he put the name Avenue Blue to rest.

单飞至今，只发过十张个人专辑的他（其他則是以*enue Blue 这个团体名义发行），在这张专辑中，再次遊走在跨界和灵魂即兴爵士边缘，靠着強烈的即兴独奏，让人对他的音乐发展进程再度侧目。

Olive oil: 40 years ago, has come from seven countries, the Institute reported that monounsaturated: The olive oil contained inside only one double bond or triple bond-containing compounds, particularly of fatty acids (such as oleic acid have great to reduce the prevalence of heart disease and cancer.

1：橄榄油，40年前，来至7个国家的研究所报告指出单不饱和的：橄榄油里含有只含一个双键或三键的化合物，尤指脂肪酸(如油酸具有很大减低心脏病和癌症的患病率。

If one abnormal parathyroid gland and a normal gland are found on the first side of the neck that is explored,the other should not be explored.

术前、术中的准确定位及冰冻病理的定性检查是手术成功的关键。一侧甲状旁腺中仅有一个病变者可只行单侧探查。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
