Testing results of piles under low strain integrity are normally interpreted using one-dimensional stress wave theory. While one-dimensional stress wave theory is acceptable for pile-driving analysis the responses of piles integrity tests can not be adequately simulated when the hammer and the incident wave length are small in relation to the diameter of the pile.

The effects of such parameters as temperature, pH, feeding rate,concentration, [NH_3]_T/_T molar ratio, surfactants and agitation, on the morphology and size of the particles, were studied and conclusions obtained are as follows:(1) The morphology and size of the particles are mainly decided by the species of nickel oxalates present.(2) Speeding up dissolution-recrystallization process benefits the preparation of the particles of being composed of a single species with uniform morphology and high aspect ratio.(3) The variations of nucleation and growth supersaturation under different conditions have definite effects on the morphology and size of the particles.(4) Adding PVP25 at a proper amount is beneficial to the preparation of fibrous nickel oxalate particles with high aspect ratio. 3 The formation mechanism as well as the morphology and size control of fibrous cobalt oxalate particlesThe cobalt oxalate particles with fibre morphology were prepared using CoCl_2 solution and mixed(NH_4)_2C_2O_4, NH_3·H_2O solution by a double jet process.
研究了温度、pH值、加料速度、浓度、[NH_3]_T/_T摩尔比、表面活性剂及其添加量、搅拌等对颗粒形貌与粒度的影响,主要结论为:(1)草酸镍化合物种类是决定颗粒形貌与粒度的最主要因素;(2)提高陈化中溶解—再结晶速度,有利于得到物相单一,形貌规整,轴向比大的粉末;(3)不同条件下,颗粒形核与生长过饱和度改变,也会对粉末形貌与粒度产生一定影响;(4)适量添加PVP25有利于大轴向比纤维状草酸镍的制备。3纤维状草酸钴的形成机理及其形貌与粒度控制采用CoCl_2溶液与(NH_4)_2C_2O_4和NH_3·H_2O混合溶液并流加料合成的方法,研究了纤维状草酸钴的制备。

The results show that WO_3 can be nitrided in the mixture gas of hydrogen and nitrogen, and ...
结果表明,WO3可以在氢氮混合气中被还原氮化;氮化反应分两段进行;在氢氮体积比(4~5)∶1,反应温度650℃的条件下,WO3可以被还原为产物W2N;在不同氢氮比的混合气中氮化,WO3会生成不同的中间产物WO2和WOXNY,中间产物WOXNY进一步氮化生成W2N要比WO2容易;助剂Ni的加入使氮化反应温度降低了100℃;载体γ-Al2O3的加入使金属氧化物的氮化过程变为一步氮化还原反应。
