ResultThe results of laboratory identification and rural productive test in Jiangsu Province show that it has excellent feeding habit, strong stress resistance, high yield, excellent silk quality and excellent fecundity. The new silkworm variety "Yesanyuan" had been approved by Silkworm Variety Evaluation Commission of Jiangsu Province in 2008, it is suitable to rear in Yangtze River catchment for Spring and Autumn, North sericultural area for all-year.

结果］经江苏省家蚕新品种实验室鉴定和农村生产试验表明，具有食性优、抗逆性强、产量高、茧丝质优良、繁育性能优的特点，并定名为&野三元&。2008年通过江苏省家蚕品种审定，适宜长江流域春、秋季及北方蚕区全年饲养。

In a two-step incubation experiment, high and low temperatures were combined with RH 70%, RH 80% and RH 90% to treat two silkworm races, Bibo x Dongtin and Chunlei X Zhenzhu, to investigate the causes for uhe occurrence of reversed silkworm in sericultural production and its hatching pattern.

针对生产上出现&逆出蚕&这一情况，通过催青实验调查发生逆出蚕的原因及其孵化方式。实验采用碧波×洞庭、春蕾×镇珠 2个蚕品种，分别在常温、高温与RH 70 %、RH 80 %、RH90 %组合的 6个条件下，进行两段式催青至孵化。

This is the socalled thin layer penetrating air drying process. The critical thickness of wet silkworm chrysalises is about 27~35 mm. In the thin layer penetrating gas drying process of silkworm chrysalises, the temperature of drying medium is subject to that at which the protein can withstand and the flow rate is subject to the allowable leakage of air from the media layer; c. For the surface convective drying process of stripe porous media e.

对于粒状多孔介质的穿流气流干燥过程，当物料厚度小于某一临界厚度时，厚度的变化对干燥过程无明显影响，即所谓薄层穿透气流干燥过程，就蚕蛹而言，临界厚度约为27~35mm；在蚕蛹薄层穿流气流干燥过程中，介质温度应以蛋白质所能承受的温度为限，流速应以穿流料层时不发生漏风现象为限；c。
