查询词典 W

None of the four models could work well in the scenario 2, under explored stock, however they got accurate results in scenario 1, regulated stock. The Schnute model work well in full explored stocks such as scenario 1, 3, 4 and 5, especially in low biomass stocks such as scenario 3, but not suitable to the under explored stocks such as scenario 2. The W-H model generally performed well in all kind of scenarios especially in scenario 1, 4, and 5. In the swordfish, xiphias gladius, fishery, estimation of W-H model and D-Fox model produced MSY about 14000 ton, very near the result of Prager in 1996.The author tentatively explored the suitable fishing condition for the models to stock assessment.

四种剩余产量模型在充分捕捞且管理良好的渔业1中评估效果较好而在捕捞不足的渔业2中效果较差；Schnute模型在充分捕捞的渔业如渔业1、3、4、5、尤其是在低生物量的渔业3中评估效果较好，但不适合评估未充分捕捞的渔业，如渔业2；Walters-Hilborn模型适用于各种渔业，尤其是渔业1、4、5；在过度捕捞渔业中如渔业3、4，模型对参数q的估计较其它参数接近真值；在北大西洋箭鱼渔业的评估中，W-H模型和D-Fox模型对MSY的估计约为14000吨，接近于Prager(1996)的结果。

三、通过分析 W在TiAl基合金片层组织中的赋存状态，以及B2相的析出机制，研究了W对片层组织稳定性及蠕变性能的影响。

The activation effect is proper when the Cu component is low, but it becomes weaker as Cu increases. This is probably due to that there is not dissolution and reprecipitation of W in liquid Cu during the process of liquid phase sintering.

含Cu量较少的粉末烧结W—Cu合金有一定的活化效果，但在含Cu量较高时，活化效果不十分明显，可能与烧结过程W不能在液相Cu中产生溶解—析出有关。

In this paper, first, the unified form of W is presented on the condition of linear unhomogeneous boundary condition under stable condition.

从稳定条件下的线性非齐次边界条件出发，给出了w的统一形式，进而将其推广到非稳定条件下的非齐次边界条件，得到w的一般的结果。

Said metal nitride is prepared through mixing the aqueous soltuion of nitrate or sulfate of A with the aqueous soltuion of Cr, Mo or W acid or one of their ammonium salts, coprecipitation or impregnation to obtain load-type or non-load-type dual-component metal salt or compound oxide, then pass in NH3, sequentially heating and azotizing at 600-750 deg.C.
