The experiment study about the subcritical normalizing holding temperature effects the macrostructure and hardness of the 40SiMnCrNiMoA steel shows: When subcritical normalizing holding temperature is 760℃, the ferrite in the mixture phase structure is lumpish, the hardness of the steel is low (about HRC32), and when the holding temperature is over 800℃, the hardness of the steel is about HRC49, the ferrite in the mixture phase structure is in old critical range austenite grain boundaries, it is disadvantage for the steel strengthening. When the holding temperature is 780℃, the mixture phase structure is mixture phase structure including the strip ferrite、martensite and bainite, the ferrite is less than 20%wt, its grains are fine and even, the hardness of the steel is about HRC38, it is in the range of HRC35-40 which is the long-life drill rod needed.

This welding wire not only has the inherent properties of metal powder-cored wire, such as with better welding quality, without slag, highly efficiency and conveniently adjusting the alloying elements etc., but also has the advantage of low hardness in as-welded (less than HRC45), good machinability, high hardness in as-aged (more than HRC55) and better wear resistance with customary working procedure on making or repairing equipments such as rollers when reasonable designing the alloys content. The author adequately makes use of the high-tempering in the required stress relieving working procedure. During this working procedure, which causes the hardness of overlaying metal increased by the reason of austenite changes into tempered martensite and more chiefly what is the precipitation of a lot of carbide by secondary hardening simultaneously. This wire can solve the hard rolled problems of some solid wires with higher alloys while it can get over the conflict of existing overlaying materials what are always possesed high hardness with poor machinability or low hardness, good machinability with poor wear resistance. Further, it also can overcome the intenerating phenomena between welding beads and make the external hardness of overlaying metal uniform. Be sure it could be found important meaning in the overlaying of wear-resistant equipments, such as the precise roller.
该焊丝除了具有金属粉型药芯焊丝焊接质量好、无渣、高效率和合金成分可方便调节等固有的优点外，合理的设计粉芯中的合金成分，按通常工序制造与修复轧辊等设备，充分利用必需的消除应力工序的高温回火，堆焊层金属在奥氏体转变为回火马氏体的同时更主要是通过二次硬化析出了大量碳化物导致硬度增加，使得该焊丝还具有焊态硬度低(小于HRC45)、机加工性能好和时效态硬度高(大于HRC55)、耐磨性能好等优点，解决了某些高合金实芯焊丝轧制困难的问题，同时克服了现行堆焊材料硬度高、加工性能差或者硬度低、加工性能好、耐磨性差的矛盾，并能克服焊道之间的软化现象，使堆焊表面硬度较为均匀，对耐磨件，譬如精轧辊的堆焊具有重要意义。

Research on Keeping Quality of Different Flesh Types of Prunus persica L.Niu Liang, Wang Zhiqiang, Liu Shu'e, Song YinhuaAbstract: Effects of post-harvest cold storage and Modified Atmosphere Package on fruit hardness, weight losing and soluble solid content of different peach or nectarine varieties were investigated. The results showed that:(1) There were obviously differences of fruit hardness among varieties of different flesh types. In room temperature, FH of '24-30' and 'Zhongtao No.2' went down slower than 'Zhongyoutao No.5' and 'Zhongyoutao No.10'. In cold storage, '24-30', FH of Zongyoutao No.5' and 'Zhongyoutao No.10' descent quickly after 2 weeks of storage while that of 'Shuguang' and 'Zhongtao No.2' quickly descent just after storage.(2) MA package could effectively slow down the decreasing of FH. There were obvious differences among different varieties while 'Zhongyoutao No.10' was less sensitive than others.(3) Soluble solid content went down after harvest and the procedure was slower in lower temperature. In room, MA package seems accelerate the descendent of SSC.
采用不同肉质类型的桃、油桃果实为材料，对采后低温和自发气调包装等对果实硬度、失重和SSC含量等的变化进行了研究，结果表明：(1)不同类型桃、油桃采后果实硬度变化差异较大，常温下24-30和中桃2号果实硬度下降较慢，而中油桃5号、10号较快，在冷库低温条件下，24-30、中油桃5号和中油桃10号两周后硬度出现迅速下降，而曙光和中桃2号在贮藏后即迅速下降，带皮硬度与去皮硬度之间有一定差异，但变化趋势基本一致；(2)MA包装能有效地延缓采后桃、油桃果实硬度的降低，在常温及低温条件下均是如此，不同肉质类型间差异明显，曙光和中桃2号非常敏感，而中油桃10号则不太敏感，即MA包装对其果实硬度降低的延缓没有其它品种明显；(3)采后桃、油桃果实的SSC含量均有一定的降低，低温下该过程较慢，MA包装在常温下有加剧SSC下降的趋势，低温下则不明显，这可能与常温下采后立即进行MA包装不利于&田间热&及呼吸热的及时散发而加剧呼吸有关。
