灵敏度

There has some intuitionist noise which declines the quality of image in the medical digital image. So we need to eliminate noise from image. To improve contrast sensitivity, display the illegible and low contrasted detail of image, We need to enhance image.

医学图像中存在着一些直观的噪声，使图像的质量下降，因此需要对图像进行去噪，为了提高图像的对比灵敏度，显示图像中较模糊、对比度差的细节，还需要对图像进行增强处理。

When the invar is paired with alloy 3Ni24Cr_3 to composea bimetal, the temperatare range of high sensitivity is also enlarged.

当它与3Ni24Cr_3配对作成双金属片时，最大灵敏度的温度范围也得到扩大。

Axial Pressure Sensitivity: Measured on axis in the far field with 1 watt input (4.0 volts RMS, 16 ohms) and referenced to 1 meter distance using the inverse square law.

轴向压力灵敏度：测量轴在远场与1瓦特输入（ 4.0伏特的电压有效值， 16欧姆），并参照1米的距离，用平方反比定律。

The method is selective and sensitive and can be used to detect the sildenafil citrate illegally added into traditional chinese medicinal preparations for invigorant.

此方法选择性强、灵敏度高，可作为分析中成药中非法添加枸橼酸西地那非的有效检测方法。

This method which avoids formation of ion-pair compounds in RP-HPLC and derivatization procedure in the detection, is quick, high sensitive and reproducible.

方法避免了传统反相高效液相色谱分析方法中离子对化合物的形成，简化了检测过程中衍生化的步骤，测定速度快、灵敏度高且重现性好。

It has been proved that the sensitivity of analytes can be significantly enhanced by adding small amounts of oxalic acid,especially for the elements with ionization potential between 9 and 11 eV.

结果表明，低浓度乙二酸对所分析元素的灵敏度具有显著的增敏效应，尤其是对电离电位在9～11eV的Be，Zn，Se，As，Sb，Hg等高电离电位元素。

Biology technique is based on appearance symptom on sweet potato or Ipomoea Setosa after they are infected to identify virus. But it need long period and is apt to be limited by season. Based on coat protein of virus, serology detects virus during peculiar immunolog...

生物学方法是依据病毒侵染后在甘薯或指示植物上的外观症状进行识别，但检测速度慢，易受季节限制；血清学技术是利用病毒外壳蛋白的抗原性，据特异性的抗体抗原免疫学反应检测病毒存在，但制备抗血清需时间长，对含量少和无蛋白外壳的病毒无法检测；分子生物学方法是以核酸为基础，通过检测病毒核酸来证实病毒的存在，该技术具有灵敏度高、特异性强、适应范围广等特点。

Biology technique is based on appearance symptom on sweet potato or Ipomoea Setosa after they are infected to identify virus. But it need long period and is apt to be limited by season. Based on coat protein of virus, serology detects virus during peculiar immunology reaction of antibody and antigen. But it can't detect virus without CP and preparing antibody need more time. The molecular biology method is based on nucleic acid to detect virus. This technique has high sensitivity, strong veracity, wide suitability etc.

生物学方法是依据病毒侵染后在甘薯或指示植物上的外观症状进行识别，但检测速度慢，易受季节限制；血清学技术是利用病毒外壳蛋白的抗原性，据特异性的抗体抗原免疫学反应检测病毒存在，但制备抗血清需时间长，对含量少和无蛋白外壳的病毒无法检测；分子生物学方法是以核酸为基础，通过检测病毒核酸来证实病毒的存在，该技术具有灵敏度高、特异性强、适应范围广等特点。

The results show that mesoporous and hollow SnO2 gas sensor has higher sensitivity and nice response-recovery characteristic to alcohol, hydrogen, but it has no sensitivity to carbon monoxide, isobutane, benzene and so on.

采用静态配气法对材料进行了气敏性能测试，结果表明：介孔和空心球氧化锡元件都对乙醇、H2表现出较高的灵敏度和良好的响应特性，而对CO、异丁烷、苯等不敏感。

The sensitivity and specificity of differential pacing in predicting isthmus conduction were 100% and 88.9% respectively.

差异性起搏对预测峡部完全阻滞的灵敏度达100%，特异度达88.9%。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
