TDV

Based on the analysis of change of soil water potential ( SWP) and soil temperature ( ST), we researched the daily trunk diameter variation ( DTDV) and trunk diameter variation ( TDV) of peach in winter.

在分析空气温度、土壤水势以及土壤温度生态因子变化的基础上，研究了桃树茎干日变化规律以及冬季桃树的茎干变化。

Series TDV TripleDuty Valves are designed for use on single, double, and vertical in-line pump applications.

系列TDV三用阀适用于单个 、 两个和垂直并联泵应用场合.

The geometric nonlinearity of struction is considered with the actual situation of the bridge. Thirdly, the Midas/ Civil and TDV finite element model of this structure is established, and the first kind buckling problem is calculated and analyzed.

结合背景桥梁的实际情况，主要考虑结构的几何非线性。再次，建立结构的Midas/Civil和TDV有限元模型，计算分析桥梁的一类稳定问题。
