将阀门保持在这个位置，当安全阀出现可以看到的第一次排放的同时，观察仪表读数。
Hold the valve at this position and observe the reading at the moment the first discharge is noted from the relief valve.
该方法基于共轴球面光学系统的成像原理，通过读数显微镜对吸入待测液体后毛细管的焦点位置进行单一参数的测量，进而计算出待测液体的折射率。
The refractive index was obtained through measuring the focal position of a capillary filled with the liquid by a reading microscope, and doing a calculation with an analytic formula.
通过比较每个位置的平均读数，去掉正常的水位变动，他就能计算出湖底层的任何变化。
By comparing the average readings at each place and filtering out normal water movements, he can calculate any changes in land levels.
在获取流量测量读数之前，将阀门设置在全开(4.0)或在一个预调的位置。
Before taking a flow measurement reading, set the valve to its fully open (4.0) or at a preset position.
他最后表示，总的来说，心率监测器的佩戴位置离心脏越远，其读数的误差也就越大。
In general, the further away from the heart a body monitor is located, the more variation there will be in heart rate readings, he said.
