平稳值

There were two great fluctuations and the stock returns were fluctuated,non-asymmetric and leptokurtic,being stable under 10%,5% and 1%.

股价收益率具有显著的波动集聚性，且表现出&尖峰、厚尾、非正态&的特征，在10%、5%、1%临界值水平下均存在显著的平稳性。

By way of eight experiments and statistical analysis of loads of overhead crane in actual usese, we have got that the lifing load is stationary, normal and homogeneous Poisson, and got distribution function of lifting load, the load spectrum factor, the rain-flow counting results of stresses and statistical results of location of the trolly, that will provide a large number of datas for reliabilitic design of overhead crane.

通过对八台桥式起重机现场使用载荷的实测试验与统计分析，得出桥式起重机吊重载荷的平稳性、正态性、齐次泊松性、幅值分布、载荷谱系数，以及应力的雨流计数结果、小车位移分布等，为桥式起重机可靠性设计提供了大量的统计数据。

Since the inertial force of piston depends on its mass when the piston reciprocates at high speed, the tolerance of piston mass must be strictly controlled during design and manufacturing, so as to ensure engine operate smoothly.

活塞重量大小决定其高速往复运动时惯性力的大小，在设计和制造过程中要严格控制活塞重量的公差，以保证装机后发动机运转平稳，理论上公差值越小越好。

Results show that microbial biomass carbon and microbial biomass nitrogen in fertilized soil peak in the first several days, and then decline. Incubating both sweet maize straw and white clover have the highest yield, maxima of 529.57 mgkg^(-1) and 75.50 mgkg^(-1) respectively. They also release respired CO2 the most among all treated soils. The best mineral nitrogen release is in white clover incubating, with a maximum of 29.81 mgkg^(-1) under a 26-day culture, and then keeping 1.60 times the control and reaching 2.48 times at 80-day culture. Sweet maize incubating has the least mineral nitrogen release. It is 13%~53% of the control under a 26-day culture, with a maximum of 7.51 mg kg^(-1). Soil nitrogen mineralization is insignificant under sweet maize incubating with urea in short-term.

研究发现，各施肥处理的土壤微生物量碳、微生物量氮均在培养前期出现峰值，后期平稳降低；甜玉米桔秆和白三叶草绿肥同时还田的土壤微生物量碳、微生物量氮在各培养时期均最大，峰值分别达529.57 mgkg^(-1)，和75.50 mgkg^(-1)，土壤呼吸产生的CO2最多；白三叶草绿肥单独还田有利于土壤无机氮的释放，培养第26d无机氮达到最大值，为29.81 mgkg^(-1)，之后一直在对照处理的1.60倍以上，第80d达到2.48倍；甜玉米秸秆单独还田不利于土壤无机氮的释放，培养的第26d至结束，甜玉米秸秆处理的无机氮为对照的13%~53%，最大为751 mgkg^(-1)；甜玉米秸秆配施尿素，短期内不利于土壤无机氮矿化。

Results In 60 patients with organic diseases of vocal cords, all the acoustic parameters were significantly increased and the spectrograph showed irregularity,breakage or lack of harmonic waves and formants, and increase of noise. In 50 cases with functional voice disorder, the shimmer and NNE were significantly increased but the jitter was usually normal. The spectrograph showed pathologic changes of harmonic waves and formants in middle and high frequencies.

When plotted as a function of the degreeof reduction, the rate reaches a maximum at 11% reduction and then falls to a steady value for the rest of the reduction.

当密谋作为程度功能减少，率到达最大值在11%减少和然后下跌对平稳的价值为减少的剩余。
