两种电子根尖定位仪测量准确性的实验研究 ：采用琼脂凝胶和单根管离体牙构建EAL体外评价模型,使用两种EAL在同一种电介质中进行根管长度测量,记录测量值（measured length,ML）及测量值和实际值（actual length,AL）之间的差值（IF值）。结果采用Friedman分

仪器上记录的年代不够久远，因而无法可靠地提供一个世纪以前全球气候变化的测量值。
Instrumental records do not go back far enough to provide us with reliable measurements of global climatic variability on timescales longer than a century.
买卖双方代表要对所有测量值进行核实，并且记录在记录表上，该记录表的复印件对双方都有效。
The representatives of both parties shall check all measured value, and write them down on the record tables, the copies of record tables is valid for both parties.
正比于压差的信号（称为测量值）通过“压差变送器”被送至记录控制器。
A signal (termed the "measured value") which is proportional to the pressure difference is then transmitted by means of a "differential pressure transmitter" to the recorder-controller.
