In this paper, total logistics amounts are chosen as evaluation index, and artificial time series are designed to solve the shortness of statistical data in Chinese logistics. Spectrum estimation theory depicts time characteristics in frequency domain thus has such benefit than time domain methods. This paper evaluates the period of Chinese logistics using spectrum estimation. Stationarity of artificial series is verified, parameter sensitivity of truncation point is analyzed, six periods with different delay window are compared, and significance of period evaluated is tested.

中国物流统计数据缺乏，客观上限制了对其周期规律的研究，本文选取社会物流总额作为测度指标，设计了一种人工序列，解决了统计数据过短问题；谱估计法从频域角度揭示客观事物的时间特性，在研究时间序列周期波动方面具有时域分析法所不具备的优势，作者采用谱估计法对中国物流发展周期进行测定，检验了指标序列平稳性，分析了截断点参数灵敏度，比较了6种不同滞后窗下周期值，并检验了所测得周期的显著性。

In the process of the evaluation we got the mathematical relation between correlative parameter β, Interceptive parameter δ, and the factor M~2, using coherent beam passing diaphragm, with a numerical calculation and diagram by MATLAB.

在估算与评价过程中，利用了部分相干光通过硬边光阑的理论模型估算M~2因子，得出了光束的相干参量β和光束截断参量δ与M~2因子的具体关系式，并利用MATLAB对其进行数值计算，最后图示出它们之间的关系。

This method not only combines the best features of balanced truncation and singular perturbational method, but also reduces the possibility of physical un-realization of the reduced model obtained from generalized singular perturbation method, according to a parameter chosen in the model-order reduction process.

新算法在广义平衡奇异摄动法降阶过程中引入一个实参数代替矩阵，不仅集成了平衡截断法和奇异摄动法的优点，而且减少了计算量，大大缓解了利用广义奇异摄动法得到的低阶系统可能面临的无法实现的问题。

objective according to 14 cases of patients with post-traumatic bronchial rupture of the ct and x-ray findings.analysis of its causes,trauma type,and ct,x-ray value and the advantages and disadvantages.methods 14 cases of bronchial rupture in patients with clinical data,x-ray,ct-chip analysis and summing up.results traumatic bronchial rupture study the performance of the main image①bronchial cut-off levy;②atelectasis and pulmonary fall levy③pleural effusion,pneumatosis;④mediastinum,subcutaneous emphysema;⑤many thoracic fractures;⑥traumatic wet lung,and so on.conclusion for traumatic bronchial rupture combined with x-ray and ct examination can be clearly diagnosed early.

目的 根据14例患者外伤后支气管断裂的ct和x线表现，分析其起因、外伤类型和ct、x线应用价值及优劣势。方法对14例支气管断裂患者的临床资料、x线平片、ct片进行分析、总结。结果外伤性支气管断裂的主要影像学表现①支气管截断征；②肺不张与肺坠落征；③胸腔积液、积气；④纵隔、皮下气肿；⑤胸廓多发骨折；⑥合并创伤性湿肺等。结论对于外伤性支气管断裂结合x线摄片和ct检查是可以早期明确诊断的。

Methods 224 patients with liver biopsy and a positive HBsAg were included in this study. The AUROC of AST、ALT、AST/ALT and APRI were identified by using receiver operating characteristic curves. Sensitivity, specificity, positive and negative predictive values, and Youden Index of APRI at optima cut-off were calculated.

调查224名乙肝表面抗原阳性的乙肝患者，利用ROC曲线分析AST、ALT、AST/ALT和APRI的面积，判断APRI的最优截断点并计算不同标准的灵敏度、特异度、阳性预测值、阴性预测值、Youden指数。

Tail Length, Tail Moment, Tail DNA Percentage, and correction rate were compared between the improved software and the original one, and epidemiological indices for the improved software were also calculated and analyzed, including sensitivity, specificity, Youden index, crude agreement, adjusted agreement, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio.

比较改进前后的尾长、尾矩、尾DNA百分含量上的差异、改进前后分析正确率差异、以及改进后的软件以不同DNA损伤级别为截断值判定阳性结果的灵敏度、特异度、Youden指数、粗一致性、调整一致性、阳性预测值、阴性预测值、阳性似然比和阴性似然比。

Rocky mesas, canyons and arroyos break up the monotony of kilometers of shifting dunes.

多岩石的平地、峡谷和干枯的河道截断了绵延几千公里的单调的黄褐色地表。

And he could count himself lucky to die at 82 of heart trouble in his bed, not, like the Quint of the book, trailed behind a shark underwater, arms out and mouth open "in mute protest"; or, like the Quint of the film, chomped in half at the trouser-line, spouting scarlet blood like a whale.

在82岁的时候因心脏病逝于病床上，他应该称自己是幸运之人，因为书中的昆特船长去逝时，正在水下追猎一条鲨鱼，胳膊伸开，嘴张着，似乎在&无言的抗议&；或者电影里的昆特船长被烫裤机拦腰截断，鲜血喷涌而出，如鲸鱼一般。

An hour later, in the woods on the south side of a path on the manor's east, dirty bookworm, Huo qing-feng, is going through the woods in festinating gait while ten Kui embroidery-clothed assassins are closely going after him. Even if he constantly tries to use those burn-feeling tags to halt them, the assassins fear no more because they had experienced the effect of tag once. Besides, Huo's position is being reported by four flying sun crows so he just can't escape from the chasers. This moment, he reaches the exposed path and feels no good about this so tries to rash into the opposite woods. However, a sun crow has dived to catch his shoulder. He grasps the crow's arm with the other hand and the crow instantly release his shoulder with a sharp cry. Nevertheless, Huo is hit down by another crow's rod then three assassins rash out from the woods and wields long hooks toward Huo. Huo's mouth opens wide and he thinks he will be hauled away like a weak hen. But, all of a sudden, several shines from weapon flashes and three long hooks are cut in a blink!

半个时辰之后，在山庄东侧一条小路南边林中，脏书生霍青锋正在树丛中慌张穿行，他身后不远有十个夔纹死士紧紧追著他—他虽然不断使用那种特殊符咒试图挡住追兵，可是这些死士有了经验已经不怕了，而且他的位置一直被飞在空中的四个金乌一族盯住，所以他难以逃脱，此时他从树林中来到小路上，正觉得不妙，想赶快再钻入对面树林，一个金乌已经俯冲下来抓住他的肩，他用另一只手捏住金乌的手臂，那金乌立刻怪叫了一声把手放开，可是他很快又被另一个金乌以棒打倒在地，之后三个死士从林中窜出，对霍青锋挥出长勾，他张大嘴巴，心想这回一定会像老母鸡一样被拎走，可突然寒光一闪，三柄长勾被一瞬间截断！

I will endeavour to find you some assistance.
