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。

He was surrounded by seven armed policemen who had severely clubbed him in the head and body, maced him, and handcuffed him, in spite of his medic alert cards and jewelry. The police had even brought in dogs.

Astronomers would like to know if this is an intrinsic instability of the jet when it plows its way out of the galaxy, or if it is something else.

天文学家很想了解，当喷流沿着它的运动方向远离星系时，这种爆发现象是本身固有的不稳定喷射，还是其他什么原因。

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。
