查询词典 threshold exposure

The dissertation recommends some kinds of methods and measures: such as adjusting the network configuration, connecting value and threshold value by the total value of all stylebooks, adding part of the adjusting value of the last time to the current adjusting value, transforming the stylebooks to standard value, optimizing activation function, appending threshold value to the putout of the nerve cell and so on. Simultaneity, the author brings forward a new method to optimize the model of artificial neural network . It is using the automatically adaptive genetic algorithm to make the network configuration, connecting value and threshold value of artificial neural network better. The method can make the model better and improve the simulating effect and forecasting precision.Genetic algorithm is an arithmetic based on evolution and genetics used to search the optimization .

Results Of the observed 56 parameters of rats and mice 80.4%indicated that the threshold doses for prenatal HTO exposure ranged from 0.030 Gy to 0.092 Gy,and the other 19.6%showed the threshold doses from 0.093 to 0.300 Gy.

结果 以大鼠和小鼠为实验对象，观察的56项生物学指标中，氚的致畸阈值：80.4%的指标分布在0.030-0.092 Gy范围内，有少数指标(19.6%)分布在0.093-0.300 Gy范围内。

However, unlike most industrial particles there are no exposure limits, such as Permissible Exposure Limit or Threshold Limit Value, established for biological agents such as SARS. Therefore, respirators are not a guarantee that the user will not contract SARS.

然而，和绝大多数工业环境中存在的颗粒状污染物不同的是，SARS病毒并没有暴露限值，因此，佩戴防护口罩虽然能够帮助降低其暴露水平，却无法保证使用者绝对不接触SARS病毒，即不排除存在暴露的可能，不排除受感染，生病甚至死亡的可能。

However, unlike most industrial particles there are no exposure limits, such as Permissible Exposure Limit or Threshold Limit Value, established for biological agents such as swine influenza virus.

然而，和绝大多数工业环境中存在的颗粒状污染物不同的是，微生物，如甲型（H1N1）流感病毒没有暴露限值，如职业接触限值，因此，虽然佩戴呼吸防护口罩能够帮助降低暴露水平，却无法保证使用者绝对不接触甲型（H1N1）流感病毒，不排除存在暴露的可能，不排除受感染、生病甚至死亡的可能。

However,unlike most industrial particles there are no exposure limits, such as Permissible Exposure Limit or Threshold Limit Value, established for biological agents such as SARS. Therefore, respirators are not a guarantee that the user will not contract SARS. Respirators may help reduce exposures

然而，和绝大多数工业环境中存在的颗粒状污染物不同的是，SARS病毒并没有暴露限值，因此，佩戴防护口罩虽然能够帮助降低其暴露水平，却无法保证使用者绝对不接触SARS病毒，即不排除存在暴露的可能，不排除受感染、生病甚至死亡的可能。

After summarizing the information of Life Cycle and Health Risk Assessment, also the cost of MTBE is lower than ethanol, it shows that under manifold paths of exposure, the threshold value of cancer is without the acceptable range (10-6). The inhabitant will have high health hazard for the exposure of MTBE.

研究显示，根据生命周期评估结果，生产MTBE在能资源投入皆比燃料酒精占优势，唯需考虑MTBE属不可再生资源，而燃料酒精不但是可再生资源，且对温室气体减量具有正面助益。

It is distinctive to comparative color aberration after exposure (exposure area and non-exposure area ), easy to check board .

1。，曝光后相对色差比较明显，易于检板。

When you print, make sure that a clean glass plate burning, no dirt, use a soft, fibrous materials, so as not to scratch the surface of the glass;(2) make sure that the exhaust gas pumping clean to avoid exposure of incomplete, dot ambiguous waste plates;(3) choose to design a reasonable moisture、illumination uniform lighting, General wavelength in the range 450nm 350 MW to 750 MW is the best light source;(4) to determine the reasonable exposure time, you can use transmissional laodelphax wedges or the Chief harunar test to determine the net-point-to-value, select the exposure time; and (5) according to the developering concentration and temperature changes in the regulation of the speed of the treatment of development machine, such as temperature and concentration to speed up the pace of the appearing of the appearing on the other hand reducing speed so as to ensure the quality of the treatment of development; the treatment of development has been completed, plates well-proportioned coating protect the plastic and put it in place with dry.

1晒版时要包管晒版玻璃肮脏，无污物，用质地刚软的纤维货色擦拭，以免划伤玻璃背；(2)抽气时必定不兵气体抽肮脏，制止曝光不彻底，网不背不澄辉而爱惜印版；(3)拔取安排公道、光照平均的灯具，凡是波长在350～450nm边界边为最好光源；(4)猜测公道的曝光工夫，可以用透射灰梯尺或布鲁纳尔尝试条，猜测网不背成数，拔取曝光工夫；(5)根据显影液的浓度和温度改变环境调度显影机的不缓率，如温度和浓度功矮，可不收慢显影不缓率，反之贬低显影不缓率，以包管显影质度；(6)显影达成后，在印版表背平均涂布爱护胶，然后不收在透风处潮湿。

The flash exposure with the Canon - as far as I can see (although I might very well be wrong)- doesn't seem to take into account the exposure settings dialed in for ambient light, but instead measures just the flash exposure at the particular f-stop.

这两张照片对环境光的曝光差了一级。佳能闪灯的曝光—至少我感觉是这样，当然我也可能是错的—没有综合考虑环境光曝光的设置，只考虑了快门速度。

After 48h exposure, The GST activities were all inhibited under the exposure of phenol and pyrocatechol, but the GST activities were induced at first and then inhibited under the exposure of resorcinol.

处理48h后，体内GST活力随苯酚和邻苯二酚浓度的升高逐渐降低，而间苯二酚对GST活力的影响与处理24h后GST活力的变化趋势相似。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
