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.

亚温正火温度对40SiMnCrNiMoA的组织和硬度等性能的影响的实验研究表明,当亚温正火保温温度为760℃时,复合组织中的铁素体形态是块状,处理后的材料硬度相对较低(HRC32左右);而当采用大于800℃温度亚温正火处理,材料硬度为HRC49左右,组织中铁素体大部分较连续地存在于原奥氏体的晶界,对材料强化不利;当40SiMnCrNiMoA钢780℃亚温正火后,硬度为HRC38左右,在以往小钎杆较长寿命所需硬度范围HRC35-40内,而组织为细条状铁素体+以板条马氏体和条状无碳贝氏体为主的复合组织,晶粒细小均匀,铁素体体积含量少于20%。

White sesame E-zhi NO.2 and black sesame Zhong-zhi NO.9 were sowed at intervals as comber-sesame and autumn-sesame. The temperature and sunlight-length of different growing-stage. The result showed that seedling-stage and bud-ding-stage were temperature-sensitive and weak phototonus and temperature was the main factor in the compositive effect of temperature and light. The temperature range of 27~31℃ was optimal for sesame to produce more flowers and prolong the flowering days, but the length of flowerig-stage and practical sunlight-hour had no correlativity.

Tenderness of rabbit meat declined after slaughter, then it increased slowly. Different temperature treatment affected tender process significantly after rigor mortis (P.05): Aging rates of rabbit meat on moderate(15℃) or high(25℃) temperature condition were higher than that of low(4℃)temperature condition, but the latter had better meat quality after a slowly acid excluding period. Chilled meat (4℃) had the longest shelf life (6 days), compared with 15℃ for 3 days and 25℃ for only one day.

而低温贮藏兔肉(4℃)条件下,兔肉颜色维持的时间比较长久,同时低温也抑制了兔肉的氧化作用,TBARS值较小;宰后兔肉的嫩度呈开始下降,随后逐渐上升的趋势,不同的温度处理,对于兔肉僵直后的嫩化作用影响显著(P.05);中温(15℃)和高温(25℃)贮藏条件下的兔肉成熟速度快,低温(4℃)贮藏兔肉经历缓慢排酸后,品质好;在4℃条件下的兔肉即冷却肉货架期比较长,可以保存6d,15℃条件下3d,而25℃条件下只能保存1d。

So the present study was taken to compare the differences in the mechanisms of dissipating excess light energy in cucurbit crops and to study the differences in both the ROS metabolism in root system and the photosynthesis among six cucurbit crops with different temperature tolerance growing at different root-temperatures. The main results are as follows: 1、The species specific response of three cucurbit crops with different heat-tolerance: warm-adapted cucumber, heat-tolerant sponge gourd and heat-sensitive figleaf gourd to diurnal changes in air temperature and irradiance intensity were investigated in a typical summer sunny day. Three cucurbit species were compared using parameters in gas exchange, chlorophyll fluorenscence, photon allocation and photosynthetic electron flux.
