查询词典 double-end

According to the special requirements for centrifugal pump PIV measurement, a PIV testing platform was established to measure the instantaneous velocity in the double-channel pump with different impeller design, i.e., the double-channel impeller and the two-blade impeller, under different working conditions. The measured absolute velocity fields were transfered to relative velocity fields by specially developed code.

Based on the language materials collected, the third chapter analyses the understanding restriction conditions of "VP+NP_1+DE+NP_2" ambiguity structure from the NP_2"s life and the VP"s mobility. The author comes to the following conclusions: the NP_2"s life rank with the "VP+NP_1+DE+NP_2" structural ambiguity in understanding becomes the correlation dependence, the monosyllable verb which expresses the hands" and the foot"s movement, easily combining with the tense auxiliary, enter the "VP+NP_1+DE+NP_2" structure to form the latent ambiguity structure; the double syllable verb which has the causes feature is easy to enter the"VP+NP_1+DE+NP_2" structure to form latent ambiguity structure; the double syllable "noun-verb", with the influence of the behind noun NP_1, both can be understood as the valency combination, and the non-valency combination, thus causes the "VP+NP_1+DE+NP_2structure to appear ambiguity.

在第三章中，我们将在语料分析的基础上分别从NP_2的生命度和VP的动性这两方面探讨这一歧义结构在理解上的制约条件：NP_2的生命度等级与&VP+NP_1+的+NP_2&歧义结构理解为偏正结构的几率成正相关关系：表示手、脚等的单音节动词容易与时态助词结合，进入&VP+NP_1+的+NP_2&结构形成潜在的歧义结构；带有致使特征的双音节动词容易进入&VP+NP_1+的+NP_2&结构形成潜在的歧义结构；双音节的&名动词&由于受其后所跟的名词NP_1的影响，既能理解为配价组合，又能理解为非价组合，从而使得&VP+NP_1+的+NP_2&结构出现歧义。
