As tb is an airborne disease which can be spread from person to person via airborne droplets from coughing and sneezing of people with active tb , and that the disease exhibits a latent period which can vary significantly among individuals , the source of infection for most of tb cases is unidentifiable 由于結核病是經空氣傳播的疾病,可經患有活躍結核病的人士咳嗽及打噴嚏時所產生的飛沫,透過空氣以人傳人的方式傳播,加上該疾病在不同人士身上的潛伏期可以差異很大,因此大部分結核病個案的感染源頭都無法確定。

As the fd can not take shape overnight and has longer latent period , the fd early - warning system become necessary and possible . now domestic researches on fd prefer to look for the financial ratios , which play highly significant roles in predicting fd firms . but it is not enough for establishing early - warning system and preventing occurrence of fd 目前理論界關于財務危機預警的研究偏重于尋找最具有預測力的財務指標,這僅僅能滿足企業外部人防范財務危機的需要,而不能在企業內部真正建立防范財務危機的預警系統,從根源上防范企業財務危機的發生。

Cortical reaction comprises latent period , developmental period , climactic period and declining period . about 35s after fertilization , a few cortical alveoli begin to discharge from the low - latitudes of the animal hemisphere , later , the same pross happens in the near of micropylar apparatus , and then cortical reaction extends to the animal hemisphere and the vegetal hemisphere 皮層反應可分為潛伏期、發展期、高潮期、衰退期, 20s開始于動物極低緯度區,稍后出現在精孔器前庭附近,隨后在這兩個始發區向四周擴散。

Financial structure selection according to financial distress : on the base of trade - off theory , the article studies the relation between financial distress and financial structure - - - - discussing how to make a reasonable financial structure to prevent a financial distress . finally on the base of gregoradrade . s latent period criterion , demonstrate the article . s result jointly the real data in the chinese capital market 在財務危機與融資結構選擇的研究中:在權衡理論的基礎上研究了財務危機與企業融資結構之間的關系? ?分析了企業如何確定合理的融資結構,以預防財務危機的發生,最后以gregoradrade的潛伏期判據為基礎,并結合中國資本市場的實際數據對上述研究結果進行了實證分析。

Methods : after cultured scs combined with fn were grafted into hemi - resected lumbar spinal cords of adult rats , we used surface recording of spinal cord evoked potential ( scep ) and image analysis system to compare the latent period of scep and count the axon number between the therapeutic group and the control group 方法:將體外培養的雪旺細胞結合纖連蛋白植入大鼠半切損傷的脊髓內,用脊髓誘發電位及圖像分析方法比較治療組和對照組誘發電位潛伏期,再生軸突計數及二者間的關系。

Thus this paper puts forward the dynamic time series period analysis and prediction model . it combines the basic principle of the stepwise regression period analysis to the multiplayer - transfer method . it can not only effectively select every latent period of a time series , but also take advantage of the selected latent periods to make a long - term prediction 因此本文提出了動態時間序列周期分析預測模型,它是將多層遞階方法與逐步回歸周期分析的基本原理相結合,使之既可以有效地選取時間序列的各個隱含周期,也可以利用所選取的隱含周期作較長的時間預測。

The other research purpose is to discover characteristic information and reliable methods of reflecting spinal cord damage . due to typical damage indicators , amplitude and latent period , have bugs such as limited information and weak stabilities , this project recommends applying time - frequency analysis to monitoring spinal cord function . through analysing and comparing typical signal with stft and cwt , it is proved indicators under time - frequency distribution can be better in reflecting signal changes , espcially the wavelet transformation 針對目前ep監測中判定脊髓損傷的指標(波幅和潛伏期)存在信息量相對較小、穩定性較差的缺陷,本課題提出利用時頻分析技術對術中脊髓功能監護進行研究,通過短時傅立葉變換和小波變換分析和比較典型信號的時頻分布,證明時頻特征參數能更有效的提取信號的變化信息。

The latent period varies for different types of biological effects of radiation . the acute effect can appear from several hours to a few days , but the long - term effect may not appear after a few years 輻射對生物的損傷有潛伏期,急性效應可以在幾小時到幾天內出現,而遠期效應可能在幾年以后才出現。

Results involved in measuring burst size and latent period of the cyanophage showed that both temperature and sunlight are the important effect factors 并且,發現當溫度和光照分別為28和2000lux時,吸附率達到最大值為62 . 4 。

Among those infected , about one out of 10 will develop the disease as a lifetime risk , after a variable latent period of weeks to decades 在受感染人士當中,大約每十人便有一人在其一生中發病,潛伏期為數周至數十年不等。
