深度计

Depth of field The distande between the nearest and furthest points of the subject which are acceptably sharp.

1测深计，(2)字尺：(1)量度印刷版的蚀刻深度的测微尺。

The anchored points of each extensometer were located at depths of 8, 12, 16, 20, 24 and 30 m below the ground surface.

每个伸长计的被固定的点在土地的表面下面位于 8，12，16，20， 24 而且 30 m 的深度。

The depth of emplacement of this granite body obtained by the hornblende geobarometer is up to 24.5 km.

摘 要：锆石U-Pb年龄表明鄂东月山岩体是一个古老花岗岩经后期重熔并于燕山中期(139Ma)侵入的花岗岩体，角闪石压力计得出侵位深度达24.5km。

Those MEp that occurred as subsolid mineral with or without resorption of earlierformed hornblende, can be use as pressure indicator for intrusion.

而晚期近固相线晶出的绿帘石时，能够作为压力计反映岩体最小侵位深度。据此可以应用于对地壳演化和隆升的研究。

MEp which crystallized earlier than biotite or hornblende in the magma, can not be used as a barometer, but be useful in caculating the ascent speed of magma.

作为早期结晶的矿物，绿帘石不能作为压力计来反映岩体侵位深度，因为在绿帘石晶出时，岩浆中液相体积在50%～80%，这样岩浆可能会有快速侵位的过程，但它的地质意义在于能够对岩浆上升速率做出估算。

The suitable buried depths of tensiometers used for drip irrigation scheduling of tomato should be determined based on the buried depth of drip tape. The experiments recommended that one tensiometer should be installed just below a drip tape at depth of 30, 50 and 70 cm for the lateral depth of 0, 15 and 30 cm, respectively.

建议采用负压计制定灌溉计划时在毛管所在垂直剖面上安装1支即可，该研究条件下，毛管埋深0、15和30 cm时，用于制定灌溉计划的负压计宜分别埋置在毛管所在剖面上30、50和70 cm深度。

Finally, twelve monthly binning secchi depth maps are build by using 1988 MODIS images from 2004 to 2007. The results show annual variation of secchi depth, absorption coefficient, and backscattering coefficient.

最后利用推估结果较佳的波段与关系式，将2004年至2007年共计1988张MODIS影像，叠合成1至12月份计12张台湾海域的沙奇盘深度推估影像，并分析其四年的变化，结果显示台湾海域的沙奇盘深度与吸收系数，以及背向散射系数皆有年的周期性变化。

In radiation dosimetry there are numerous limitations associated with the measurement of isodose curves and depth-dose distributions in high gradient regions of beams by using conventional measuring systems, such as ionization chambers, diode dosimeter, thermoluminescent detectors, and radiographic films.

在辐射剂量学中，利用传统的剂量计例如游离腔、二极体侦检器、热发光剂量计、感光胶片…等，来量测等剂量曲线或是深度剂量分布都有其适用的范围及其限制。

"First we calculated distances from the external contour to the distal end of the tumor using the CT images of the patient," he said."The depth values were then mapped to a coronal projection of the PTV. Then we binned the depth values to the target energies."

他指出，首先我们透过病患的CT影像计算自外在轮廓到远端肿瘤边缘的距离，接著将深度数值与「计画目标体积」PTV的冠状投射范围对照，然后将深度数值放进目标能量。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
