The possibilities of hexagonal boron nitride(hBN) and lithium boron nitride(li_3BN_2) transition into cubic boron nitride(cBN) under synthetic pressure 5.0 GPa and synthetic temperature 1700 K are analyzed with the use of the empirical electron theory of solids and molecules. The relative differences in electron density are calculated for dozens of bi-phase interfaces hBN/cBN, li_3BN_2/cBN. These relative differences of hBN/cBN are in good agreement with the first order of approximation(li_3BN_2/cBN are much greater than 10%.This analysis suggests that li_3BN_2 is impossible to be intermediate phase but is a catalyst and cBN should be directly transformed by hBN.

王士禛与遗民群体的交往主要集中在其五载扬州推官期间。他千方百计赢得遗民群体认可,为其在文坛以至政坛发展铺石筑路,是王士禛与遗民交往功利目的的初始。进而对遗民群体持以似有还无,若即若离甚至敬而远之的态度,是王士禛与他们交往的功利心态发展演变过程的体现。最终,"鸟尽弓藏"可谓是王士禛与遗民交往的功利目的实现之后的必然结果。王士禛对遗民群体的"用行舍藏",顺利完成了自己文学地位的确认以及政治功绩的积淀,某种程度上也使其成为了满清统治者怀柔文化政策的执行者。
