| 1. | 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 在受感染人士当中,大约每十人便有一人在其一生中发病,潜伏期为数周至数十年不等。 |
| 2. | 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,发现当温度和光照分别为28和2000lux时,吸附率达到最大值为62 . 4 。 |
| 3. | 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 辐射对生物的损伤有潜伏期,急性效应可以在几小时到几天内出现,而远期效应可能在几年以后才出现。 |
| 4. | 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 针对目前ep监测中判定脊髓损伤的指标(波幅和潜伏期)存在信息量相对较小、稳定性较差的缺陷,本课题提出利用时频分析技术对术中脊髓功能监护进行研究,通过短时傅立叶变换和小波变换分析和比较典型信号的时频分布,证明时频特征参数能更有效的提取信号的变化信息。 |
| 5. | 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 因此本文提出了动态时间序列周期分析预测模型,它是将多层递阶方法与逐步回归周期分析的基本原理相结合,使之既可以有效地选取时间序列的各个隐含周期,也可以利用所选取的隐含周期作较长的时间预测。 |
| 6. | 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:将体外培养的雪旺细胞结合纤连蛋白植入大鼠半切损伤的脊髓内,用脊髓诱发电位及图像分析方法比较治疗组和对照组诱发电位潜伏期,再生轴突计数及二者间的关系。 |
| 7. | 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 皮层反应可分为潜伏期、发展期、高潮期、衰退期, 20s开始于动物极低纬度区,稍后出现在精孔器前庭附近,随后在这两个始发区向四周扩散。 |
| 8. | 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 目前理论界关于财务危机预警的研究偏重于寻找最具有预测力的财务指标,这仅仅能满足企业外部人防范财务危机的需要,而不能在企业内部真正建立防范财务危机的预警系统,从根源上防范企业财务危机的发生。 |
| 9. | 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 由于结核病是经空气传播的疾病,可经患有活跃结核病的人士咳嗽及打喷嚏时所产生的飞沫,透过空气以人传人的方式传播,加上该疾病在不同人士身上的潜伏期可以差异很大,因此大部分结核病个案的感染源头都无法确定。 |
