Shwachman-diamond syndrome （SDS） is a mult.-syst.m disorder charact.rized by bone marrow failure, pancreat.c insufficiency, skelet.l abnormalit.es, and increased risk of leukemic t.ansformat.on. Most.pat.ent. wit. SDS cont.in mut.t.ons in t.e Shwachman- Bodian-diamond syndrome gene （SBDS）, encoding a highly conserved prot.in t.at.has been implicat.d in ribosome biogenesis. Emerging evidence also suggest. a dist.nct.role of SBDS beyond prot.in t.anslat.on. Using t.e yeast.model of SDS, we examined t.e underlying mechanisms t.at.cause cells lacking Sdolp, t.e yeast.SBDS ort.olog, t. exhibit.reduced t.lerance t. various st.ess condit.ons. Our analysis indicat.s t.at.t.e environment.l st.ess response （ESR）, heat.shock response （HSR）, and endoplasmic ret.culum unfolded prot.in response （UPR） of sdolA cells are funct.onal and t.at.defect. in t.ese pat.ways do not.produce t.e phenot.pes observed in sdolh yeast. Deplet.on of mit.chondlial DNA （mt.NA） was observed in sdolh cells, and t.is is a probable cause of t.e mit.chondrial insufficiency in SDS.

建立了聚晶金刚石(PDC)钻头切削齿切削岩石过程的有限元模型,模拟了不同形状切削齿不同切削深度下的线性和圆弧切削过程。模拟前确定了切削齿的空间形态、切削速度、切削深度、材料的流变模型、摩擦模型等。模拟结果表明:线性和圆弧切削过程没有本质区别;各类切削齿的切削力波动均为振荡和不均匀的,不存在周期性;采用同一切削齿时不同切削深度下的切削力波动没有类似规律,但切削深度增加会引起波动幅度增大;切削深度为0.5 mm和1.0 mm时,切削参数保持稳定后平均切削力减小,而切削深度为2.0 mm时,进入稳定切削区后平均切削力并未减小;使用球形齿和圆锥形齿时切削力较小,而使用锥形齿、斜角形齿和平板形齿时切削力较大;采用平板形齿时切削力波动图上单位时间内峰数最少,采用球形齿时最多。
