喷射

However,their effects upon the rice leafhopper,Empoasca subrufa Melichar,remain to be carefully investigated.Experimentswith adults were conducted both in the laboratory and in the field.The resultsmay be summerized as follows:1.Spraying with 25% DDT emulsion in 200-300 parts of water killed over90% of the leafhoppers,whereas in 400 parts of water,it gave an unstable kill-ing effect ranging from 75% to 90%.Dus...

田间使用 DDT 防治白翅叶蝉的残效期约为10—12天。666单独用来防治白翅叶蝉效果甚差，但与 DDT 混合使用有增效作用，残效期与单独使用 DDT 相似；二者混用是最合理的施用方式，可以节省 DDT 用药量，减低药费，同时对多种稻虫可收综合防治之效。25%DDT 乳剂和6%可湿性666按1∶1∶400及1∶1∶600混用，其毒效相当于单用 DDT 1∶200及1∶300者；用1∶1∶500喷射效果比单用 DDT 1∶300者还略高；5% DDT 粉剂和0.5%666粉剂按1∶1混用，其毒效也和单用5% DDT 粉剂相接近。

When the squirt flow mechanism occurs, the squirt flow mechanism dominates the contribution to the energy loss of compressional waves at low frequencies.

依据非牛顿流体饱和各向同性孔隙介质BISQ声学模型，喷射流动只影响纵波的频散和衰减，而饱和流体的非牛顿流效应不仅影响纵波，而且还影响横波的频散和衰减。

Some facilities resort to to spray foam, silicone, shrink wrap with sheet metal with screws to hold it down.
