By the combination of experimental results with theory of crystal growth, some growth models and growth mechanisms were proposed. Research results confirmed that pillar-shaped TaC whisker with spherical droplet at the end grew via a vapor-liquid-solid mechanism, pillar-shaped whisker with pyramid-like end was formed via a vapor-solid mechanism, awl-shaped TaC whisker with zigzag end formed via a liquid-solid mechanism, awl-shaped TaC whisker with growth step at the end has a growth mechanism of screw dislocation mechanism. The growth mechanism of dumbbell-shaped MgO nanowhisker and NaCl particle-decorated MgO nanowhisker is VS; C and MgO powder-yielded MgO nanowhisker was formed via a VLS mechanism, Mg powder-yielded MgO microwhisker and MgO microsized or nanosized crystal sheet grew via a VS mechanism. In the Si and SiO〓 nanostructures, Si nanowires formed in higher-temperature zone grew via oxide-assistant mechanism, while Si nanowires or nanorods formed in lower-temperature zone have a growth mechanism of VLS, and the growth mechanism of SiO〓 nanowires is VS.

On this base, the further investigations were done in other systems without MgCl2: the systems of saturated solution of Ca2 and CO2, of CaCl2 and Na2CO3, of CaCl2 and urea. The results showed that the necessary conditions to prepare uniform aragonite whisker were an elevated temperature and low super saturation to assure the separation riucleation stage from growth stage in a stable system. Thus, the function of MgCl2 in Ca2-MgCl2-CO2 was not only being adsorption at crystal nucleus to develop it toward aragonite, which was described by other researchers, but also the more important functions were, firstly, avoiding calcium carbonate to grow toward calcite relying on Ca2 as nucleus by converting solid-gas system to liquid-gas because of the reaction between MgCl2 and Ca2; secondly, the produced Mg2 made the pH value of system be kept at ~9, as a result, the distribution of CO2 in the solution was decreased.
在此基础上，进一步地对无Mg~(2+)参与的Ca_2饱和溶液-CO_2液-气体系、CaCl_2-Na_2CO_3和CaCl_2-尿素液-液体系进行了实验研究，证实了维持适当高的温度和较低的碳酸钙过饱和度，保证其成核与生长的分离是获得均一文石相碳酸钙晶须的必要条件，从而揭示了Ca_2-MgCl_2-CO_2体系中，MgCl_2的作用不仅仅是Mg~(20)吸附在碳酸钙晶核上促进其向文石相发展，而且更重要的是利用MgCl_2与Ca_2的反应将Ca_2-CO_2固-气反应转化为较易进行的液-气反应，避免了以固相Ca_2作为晶核生长成方解石。
