nvi

My pick is nvi , which I find a little more comfortable and familiar with the ever-present vim .

我选择的是nvi，我觉得它比一直存在的vim更好用和更熟悉一些。

Research was performed aiming at the low recovery rate of the waste recovery system and the high pH , high sulphate and high NVI ( non-volatile impurities ) in the sodium thiocyanate product .

本项目针对大庆石化公司腈纶厂污水回收系统存在的硫氰酸钠回收率低、硫氰酸钠产品的pH、硫酸根和NVI（非挥发性杂质）含量等指标过高的问题开展研究。

Finally , a NVI map excluding non wheat image cells and a stratified ecological map were integrated , from which the growth of wheat seedlings was graded according to the indices and the accuracy of monitoring was increased .

最后，将剔除常年非麦象元后的NVI图与遥感生态区分层图进行集成，采用不同指标划分小麦苗情等级，从而提高了小麦苗情遥感解译精度。
