The results show that in the case of {1 0 0}, the morphology of crystal changes from lowtemperature sheet to hightemperature tower with increasing the synthesized temperature, whereas in the case of {1 1 1} the change trend is contrary to {1 0 0}. When {1 1 1} facet or {1 1 1} was used as the growth facet, the sheetlike crystal is more difficult to incorporated for the metal inclusion regardless of synthesized temperature. With NiMnCo metal as solvent, large highquality gemgrade diamonds can also grow on {1 1 1} facet with proper temperature gradient.

结果表明：随着合成温度的升高，用{1 0 0}面生长出的晶体形貌由低温片状逐渐过渡到高温塔状，而用{1 1 1}面生长出的晶体形貌变化趋势则相反；采用籽晶{1 0 0}面或{1 1 1}面生长晶体，无论合成温度高低，包裹体都不容易进入片状晶体内部；只要存在合适的温度梯度，NiMnCo触媒同样适合利用籽晶{1 1 1}面生长优质大尺寸宝石级金刚石（≥4 mm）。

Applied overlay principle discloses intention at the complex load of break of grease wall of a well for individual and simple load, through set and time relevant aeriform pressure distributings function, rupture according to flexibility of stretch and mechanical, line condition of tie of stress of the upland after perforation of well of grease of mechanical and academic derivation plays factor of intensity of interstitial and most advanced stress, got deflagrating patulous condition is cracked since terrane of aeriform fracture wall of a well, the aeriform pressure gradient that this condition can follow time change inside reflective break is right the influence of interstitial configuration.
