Int.oduct.on: Pest.cides are current.y an essent.al component.of agricult.ral product.on t.chniques for cont.olling pest. and weeds. In b.rkina Faso, non-compliance wit. good pract.ce in t.e use of pest.cides poses a real healt. prob.em for t.e populat.on. t.is st.dy examines t.e healt. risks associat.d wit. pest.cide management.in rice-growing areas. Mat.rial and Met.ods: A field survey was conduct.d in b.ma, involving farmers, focusing on t.eir socio-demographic charact.rist.cs, pest.cide usage, and healt. effect.. Cholinest.rase levels were measured in sub.ample of farmers using a port.b.e device. Dat. were analysed using Microsoft.Excel, calculat.ng means and percent.ges for various pract.ces. Healt. consult.t.ons, prot.ct.on met.ods, and pest.cide management.were st.died. Eryt.rocyt. acet.lcholinest.rase act.vit. was compared b.fore and aft.r t.eat.ent. Dat. were cat.gorised int. classes b.sed on inhib.t.on levels, and correlat.on analyses det.rmined relat.onships b.t.een variab.es such as age, years of experience, and cholinest.rase act.vit.. Result.: t.e result. indicat. t.at.rice cult.vat.on is mainly carried out.b. a fairly young populat.on, wit. nearly 63% b.ing under t.e age of 50. Common poor pract.ces in pest.cide use include improper st.rage and reuse of left.ver pest.cides. Seven t.pes of pest.cides were ident.fied, including organophosphat.s such as glyphosat., which was used in 26.7% of cases. t.is organophosphat. has result.d in class b.poisoning, causing a 30% - 50% reduct.on in eryt.rocyt. cholinest.rase act.vit.. t.e healt. effect. of pest.cide use are felt.b. agricult.ral farmers t.rough various sympt.ms of poisoning. Conclusion: t. reduce t.e occurrence of pest.cide poisoning, it.is essent.al t. launch informat.on and awareness campaigns among t.e populat.on and farmers t. promot. safe pract.ces in pest.cide use in b.ma, b.rkina Faso.

激光再制造是用于再制造的一项重要技术,在航空航天、冶金、能源等领域应用广泛。然而,形状控制问题一直是制约其规模化和工业化应用的瓶颈。在激光再制造过程中,熔池温度是决定再制造件形状和性能稳定性的关键。基于此,本文提出了一种基于状态空间模型的激光再制造熔池温度实时在线控制方法,解决了控制机理模型难以建立和多变量约束的问题。
