绝对阈值

以血清维生素A含量，相对剂量反应（RDR）和暗适应功能（暗适应恢复时间和绝对阈值）检查为指标，在严格膳食控制下，进行了60天实验。

The serum retinol , relative dose response ( RDR ) and dark adaptation function ( dark adaptation time , absolute threshold ) were determined .

快速暗适应时间在1分钟以内，（3）视网膜光感绝对阈值，看到0.2×10~（-6）asb视标，时间不超过30分钟；

Dark adaptation time within one minute ; ( 3 ) retinal photosensitivity ( absolute threshold ) down to 0.2 × 10 - (?) asb within 30 minutes ;

并对绝对阈值和植被指数进行修正。

Also , the paper fixed absolute threshold and vegetation index .

非附件一缔约方可提议部门排放量绝对阈值，作为其低碳发展战略的一部分。

Parties not included in Annex I may propose absolute sectoral emission thresholds , as part of their low-carbon development strategy .

暗视α波的大部分能为很弱的明适应光所抑制，这个明适应光的强度大约只相当于绝对阈值的1000倍。

A major portion of a_s could be suppressed by a weak light adaptation , the required intensity being only 10 ~ 3 times the absolute threshold .

用阈值处理细节系数对1到N层选定阈值，并进行硬阈值处理，把绝对值小于阈值的系数置为0。

The detail coefficient is processed with threshold value that the value of 1-N layer chosen , and harh-threshold value is processed .

它先对匹配像素用动态阈值分类，若灰度绝对差大于阈值，再使用最小绝对差平方累加和作为相似性度量。

It classifies matching pixels by dynamic threshold . If absolute difference of gray value is more than threshold , it counts the minimum absolute difference square of the gray level of the two images .
