In order to detect four kinds of unusual voices, we extract five features on audio waveform, including the number of segmented parts, duration of waveform, mean of volume, zero crossing rate and correlation. Experimental results show that the detection rate can be up to 94%~97% for these four kinds of unusual voices.

为侦测上述的四种危急声音，我们从声波图上撷取区域内声音区段的数目、波形持续时间、平均音量、正规化零越率和声音区段彼此之间的相关性五种具区别率的特徵为我们侦测之依据。

Mars will remain in your workaday sector from October 13 to June 7, an enormously long time for Mars to be.

火星将会在10月13日到明年6月7日停留在你的工作区域，这将是一段异常漫长的时间。

It takes 8 minutes to zhong guan cun area, and only take couple minutes to Xiangshan park and summer palace.

This paper reports the results of highly precise zircon SHRIMP U-Pb dating of quartz albitite in the volcanic-sedimentary series of the Tuolugou cobalt deposit, Golmud, Qinghai. Analyses of eight spots presented 206Pb/238U ages of 455 to 483Ma with a weighted mean age of 468±9Ma, which represents the timing of submarine volcanic exhalation in this area. Therefore, the age of the host rocks of the Tuolugou ore district is redefined as Ordovician, which implies that regionally the main part of the Naij Tal Group should be Early Paleozoic in age.

青海格尔木驼路沟矿区赋矿火山－沉积岩系中的石英钠长石岩样品锆石SHRIMP U-Pb精细测年结果表明，该岩石具有一组8个测点构成的455~483Ma的206Pb/238U年龄数据，加权平均年龄为468Ma±9Ma，应代表本区海底火山喷流作用的时间，因此重新厘定了矿区内含矿岩系的时代为奥陶纪，同时，这一年龄指示区域上纳赤台群主体的时代应为早古生代。

Thepercentages that solar energy captured by greenhouse macro-environment horizontal surfaceand backwall would decrease a little,and the solar energy on the south vertical surface ofthe canopy would be 10%～20% of that transmitted into the greenhouse.

白天中大部分时间内主体水平面上80%的区域中太阳辐照度分布比较均匀，后墙的散射反射有利于改善主体水平面上的太阳辐射分布状态。当室内存在充分发展的冠层时，主体水平面上的太阳辐射分布趋于均匀。

Based on the definition of desertification from the United Nations Convention to Combat Desertification,the potential extent of desertification in China was revised by employing Thornthweite＇s and Penman＇s formulae to calculate humidity index using the records of 671 meteorological stations from 1950 to 1990,and the biogeographical features of the climate types were clarified.

为了客观反映中国荒漠化发生区域，按照联合国防治荒漠化《公约》的定义，利用1950—1990年间全国671个气象站的长时间序列气象数据，分别采用Thornthwaite和Penman计算可能蒸散量的方法计算了湿润指数的分布，然后根据中国气候区划和中国植被区划以及中国荒漠化发生的特点等对计算结果进行了调整，对中国荒漠化潜在发生范围进行了修订，明确了荒漠化各气候类型区的地理涵义。

In order to prevent the bootlegging at the rest time,it was added the function of setting time which was made through the keys.

At each time point, we observed morphological changes, in situ detected DNA breaks, and observed expression changes of production of lEGs c-Fos and DNA repair enzyme APE/Ref-1 which participated in many kinds of DNA repairs. Results in the experiment were shown as follow:DHE stain indicates: The model of rat MCAO/R was credible, and the damaged regions included cortex (lobus frontalis, lobus arietalis, lobus occipitalis et al and caudatum.

本次实验采用大鼠大脑中动脉阻塞再灌注模型，将健康雄性SD大鼠随机分为正常组、假手术组和MCAO2h再灌注2h、6h、12h、24h、48h、72h组，观察各时间点损伤区域神经元和细胞的形态学变化，原位检测DNA断裂损伤，检测DNA修复酶APE/Ref-1表达变化情况以及IEGs产物c-Fos表达变化情况。

Field investigation and analyses of the grain size, geochemical, stable carbon isotope etc climate proxies all indicate that this region, in about 14000aBP, u nderwent the expansion of the swamp. Subsequently, the swamp, because of aridity , began to decrease in area, and even disappeared. This process was followed by an immediate flooding period. The region, after the Younger Dryas cooling event (108000～10200aBP), came into the warming period of the Holocene, and then clima te in the region fluctuated subsequently.

张强通过区域地貌调查及对南京浦镇林峰桥剖面沉积物进行粒度、地球化学和稳定碳同位素等环境替代指标的分析研究，结果表明：本区在14000aBP左右先后经历了沼泽扩张期，此后气候变干，沼泽开始退缩，直至消失，在经过了长时间的沉积间断后又经历一次洪水泛滥期。

Research results indicate that continuous Regional Identification Function is used in nodal virtual flux method, volumn integral and surface integral enhances the convergence and stabilization;using 'put a big number' to deal with the first boundary is faster than 'Remove row and column', the more the first boundary nodes are the more obvious advantage will display;PCG method is quite faster than Crout method to solve equations;it is reliable to use three-dimensional finite element simulation theories to simulate and predict deep foundation pit dewatering in such areas.
