In our experiment, we found two abnormal phenotypes that one only the last three segments develop into pupa, but the other segments are still keep the larva characters; another sample has differently develop speed between abdomen and backside, which resulted in the back develop into pupa but the abdomen were still the larva characters. When we add Az in the feed of injected EcR-dsRNA samples, in the 13 live larvae we found that 6 have the abnormal proleg phenotypes.
在另一组注射EcR-dsRNA以后通过浸叶法添食不同浓度的印楝素,在10ppm处理组存活的13个个体中有6个出现特异表型,其中两个幼虫为不完全蜕皮,尾部体节无法蜕皮导致发育受阻;另外发现4个供试虫体发育至五龄时出现腹足缺失表型,其中有两个是腹足几乎全部缺失,腹足应该生长的部位只有少数几个突起,没有发育成形的腹足;一个出现左侧腹足完全缺失,右侧第二腹足缺失表型;另一个个体只缺失了左侧最后一个腹足。

It is shown that the microstructure of ZJ510L is refined by increasing the rolling pass and the cooling rate. The size range of final ferrite is about 5-6μm. Precipitates consist mainly of Al2O3, MnS, AlN and lots of carbonide particles, and their size range is about 20-150nm. It is verified that ZJ510L steel possesses a good combination of strength and plasticity due to its fine microstructure and has excellent formability and notched bar impact strength.
通过光学显微镜、透射电镜和力学性能实验研究表明:ZJ510L显微组织随著轧制道次和冷却速度的增加而细化,最终铁素体晶粒尺寸约为5~6μm;析出的第二相粒子主要为Al2O3,MnS和AlN以及大量的碳化物,尺寸大多在20~150nm之间;成品板强度和延伸率较高,并具有良好的成形性能和低温冲击韧性。

The Hedgehog morphogen governs cell differentiation and proliferation in a diverse array of patterning events in many animal species, ranging from insects to mammals. The seven-transmembrane protein Smoothened transduces the HH signal across the plasma membrane but molecular mechanisms of its activation are poorly understood. Zhao et al .
Hedgehog形态发生素在从昆虫到哺乳动物在内的很多不同动物物种的各种不同成形事件中决定细胞的分化和增殖。7-跨膜蛋白Smo跨越胞质膜传导Hh信号,但科学家对Smo激发的分子机制却很不了解。

The results shows that the flow characteristics of SiC-AlN granulated powder is obviously promoted after spray drying and a suitable particles grade match. With the increasing of pressure, the density of green body increases by the style of ladder at the pressure range of 4080 MPa, 80160 MPa and 160220 MPa, the green body is uniform and densification without hard pelleted particles above 160 MPa. The pressureless sintering SiC-AlN multiphase ceramic possesses superior sintering properties and mechanical properties. It is due to the rampart formation of AlN to SiC grain growth and the reaction of SiC and AlN to form 2H solid solution. It results in the grain fining, crack expansion producing bypass and deflection, fracture section producing tearing-open and pulling-out effects, which cooperatively improves the strength and fracture toughness of the multiphase ceramics.
结果表明:喷雾造粒后,复合粉体的流动特性显著提高,粒度级配合理;随着压强增加,坯体密度在40~80、80~160和160~220 MPa范围内呈现阶梯式增长,160 MPa以上成形后素坯均匀致密,无硬球颗粒存在;无压烧结SiC-AlN复相陶瓷具有优越的烧结性能和力学性能,这是由于AlN对SiC晶粒形成生长势垒,并反应生成2H型固溶体,从而细化晶粒,导致裂纹扩展产生了绕道与偏转效应,呈现晶粒撕裂与拨出现象,协同改善了复相陶瓷的强度及断裂韧性。
