查询词典 light intensity

The behavioral responses of sea cucumber to different light intensity (100, 50, 10, 5, and 1 lx) and settlement substratum color (red, gray, yellow, blue, white, black, and green) were examined by mean phototactic rate and mean attractive rate methods. The results showed that the MPR was significantly different (P.05) among strong light regions (100, 50, and 10 lx)(P.05), but was not between weak ones (5 and 1 lx).

为了探讨刺参的趋光特性和附着基颜色对其行为反应的影响，分别用平均趋光率(mean phototactic rate， MPR)和平均聚集率(mean atteactive rate， MAR)统计分析了刺参在100、50、10、5和1 lx共5档强度的光照和7种颜色的附着基（红色、灰色、黄色、蓝色、白色、黑色和绿色）下的行为反应差异。

SM and DTT resulted in stronger degree of reducement in Fv/Fm, qP, F'v/F'm and TPS II when broccoli leaves were treated with strong light.

Based on the technique of PIV,We calculated the light intensity of the bubble interface and discovered that the intensities of lighr reflected or refracted twice succeedingly abide by the rules of geometric series , and the light will disappear after reflecting or refracting 4 times by the bubbles.

基于粒子成像测速的流体可视化技术，根据菲涅耳公式计算了入射到水中气泡界面的光强，得出点光源连续两次反射或折射的光强具有等比数列的规律，光线在气泡界面反射、折射4次就变成完全偏振光且光线几乎消失。

To elucidate the biological structure basis of transgenic rice plants expressing maize PEPC gene with high photosynthesis efficiency, PEPC transgenic rice and its wild type with at 3 leaves seedling stage were treated under 1000 μmol/(m^2s) light intensity for 100 min, respectively, and those under 200 μmol/(m^2s) light as the control. The structure of mesophyll cells, bundle sheath and thylakoids of the second blade were observed with a transmission electron microscope.

为了阐明转玉米PEPC基因水稻高光效的结构基础，以转玉米PEPC基因水稻和未转基因原种为试验材料，在水稻的三叶期，施以100min，1000μmol/的高光强处理，以200μmol下的水稻为对照，运用透射电镜观察叶肉细胞、维管束鞘以及叶绿体内类囊体片层结构。

For instance, the rate of photosynthesis rises with increasing light intensity as long as there is sufficient carbon dioxide available, but at high light intensities carbon dioxide may become the limiting factor instead.

例如只要有足够的二氧化碳可利用，光照强度升高时光合作用的速率就会提高，但当光照强度过高时二氧化碳反而可能成为限制因子。

The longer the lowlight and the lower the low-light intensity the longer the induction period required.Howeverthe shoot could keep its induction state during non-consecutive lightflecks unless lightfleckswere separated by a long low light period.

猝发性辐射强度越大，所需光诱导时间越长；低光期越长，低光期辐射越小，所需光诱导期越长；但只要光斑间隔不是太长，针叶仍可保持原有的光诱导状态。

Because the variation of the light source and other errors related to light intensity are not so critical for the measurement in this system and some 1/4λ wave-plates affect on the other wavelengths is very little, the retardance can be measured in high accuracy and high repeatability. In principles, the system accuracy can measure any retardance, and can be used in characteristic spectrum analysis of other phase retarders.

由于此系统可忽略光强的波动及与光强有关的误差，且1/4λ波片对多波长测试误差的影响很小，故其有很高的精度和可靠性，可以测试其精度范围内的任意小延迟量，亦可对其他光学相位延迟器件进行光谱分析。

The six cucumber materials with different low temperature tolerance were selected to be cultured in the artificial lighting incubator for 14 d under day temperature of 12 ℃,night temperature of 8 ℃,light of 8 h,light intensity of 30 μmol/(m2·s)(about 2 000 lx)and the abscisic acid,the growth hormone and the gibberellic acid(GA3) of cucumber leaves were ...

结果各黄瓜材料叶片中ABA和GA3含量均有不同程度增加，耐低温性材料越强，其增加的幅度越大，而叶片中IAA含量变化则不同，其中耐低温较强的材料增加的幅度较大，而耐低温较弱的材料有所降低，耐低温性中等的材料略有增加。内源激素含量与耐低温性的关系密切，可作为黄瓜耐低温性的间接鉴定指标之一。
