1. 實(shí)驗(yàn)上率先發(fā)現(xiàn)了二元顆粒系統(tǒng)在振動(dòng)條件下的周期性分離，并且提出理論模型來(lái)解釋其中的失穩(wěn)機(jī)制，在此基礎(chǔ)上進(jìn)一步發(fā)現(xiàn)了對(duì)稱(chēng)周期分離模式，其中的顆粒床的失穩(wěn)輪廓線(xiàn)可用地質(zhì)學(xué)中的Mogi模型來(lái)描述。

2. 設(shè)計(jì)并實(shí)現(xiàn)人工活性顆粒，研究活性顆粒在受限空間中的定向移動(dòng)與自激振蕩行為，并提出耗散彈簧模型重現(xiàn)實(shí)驗(yàn)現(xiàn)象，為設(shè)計(jì)人工活性顆粒的對(duì)稱(chēng)性破缺提供了新的思路。

3. 顆粒系統(tǒng)的靜態(tài)堆積的結(jié)構(gòu)與統(tǒng)計(jì)測(cè)量。顆粒鏈可作為理想的分子鏈實(shí)驗(yàn)?zāi)Ｐ停ㄟ^(guò)統(tǒng)計(jì)二維顆粒鏈體系的結(jié)構(gòu)特征，計(jì)算顆粒體系的結(jié)構(gòu)因子，首末端距等參數(shù)，與高分子鏈的標(biāo)度行為進(jìn)行類(lèi)比，可幫助理解高分子的標(biāo)度理論。

4. 研究連續(xù)顆粒流在多孔漏斗中顆粒流量與孔幾何特征的關(guān)系，根據(jù)實(shí)驗(yàn)中流量的標(biāo)度關(guān)系，推導(dǎo)出流量經(jīng)驗(yàn)公式，加深理解了控制流量的物理機(jī)制。
