  impact time
With the orthogonal test method, the factors that affect the erosion wear of CaO-Al2O3-SiO2 system glass-ceramic such as particles property, impact angle, impact time, size of particles were discussed.
      
With the impact time increased, the erosion rate deviates from original staight line, tendency of the erosion rate increases.
      
Load amplitude can vary with the pressure used and impact time depend on the position of the piston backstops.
      
The consideration of the variation of the unknown impact time implies for the impact problem certain new variational expressions in inequality form.
      
The small crumb rubber size was more effective in increasing impact time periods than the large crumb rubber, but had no effect on peak deceleration values.

  attack time
During wasps attacks at the hives measured at 3, 6 and 12?min, the numbers of Apis cerana cerana and Apis cerana indica bees continuing to forage were significantly reduced with increased wasp attack time.
      
Virgin females laid fewer eggs in a shorter time than did mated females (P>amp;lt;0.01), though the attack ratio and attack time of these 2 female types were the same.
      
A dynamic programming model is used to determine the maximum attack time (or distance) for each of two types of prey, differing in their energetic content, for a range of forager energy state and φ levels.
      
Attack latency, number of bites, number of attacks, and total attack time were highly correlated within each 5-min period but the correlations between periods were relatively low.
      
The control variable is the angle of attack time rate which enters the equations of motion linearly; therefore, the Hamiltonian of the problem is nonregular.

The test method of dynamic behavior of machine tool applied by a triangular inpulsive excitation is discussed in this paper. The frequency domain of the exciting signal in this method is comparatively wide and the exciting time and amplitude are easily controlled, in addition, equipments and installations used in this method such as electromagnetic exciter, signal generator etc. are common in a laboratory so that the method may easily be applied.Through tneoritical analvsis, the rules for selecting parameters such as the duration of the inpulsive force, the time interval between the samples and the trigger value have been discussed. As an example, the dynamic behavior of the spindle system in a universal lathe(c616) has also been observed by using this method.

Under simulated condition in laboratory the relationship between landing impact force and landing impact time was studied. The subjects were three male parachu-ters who were young and healthy. While jumping down from a 1,0, 1.5 and 2.0 metre platform with a load of 26.5 kg or unloaded respectively, they were being photographed by high-speed photogjaphy to record the marks on their body. After calculating the landing impact force acting on the various body segments and the peak of landing impact force acting to the feet, we found the relationships Between the landing impact time and above-mentioned froces. The results show:(1) teh landing impact force sustained in the various body segments and the peak of landing impact force in the feet were reduced with the landing impact time increasing; (2) when the langing impact time was from 0.08 to 0.26 s, the above-mentioned forces were reduced from. 40.6% to 60.1 %, as compared to their values at 0.08 s; (3) the relationship curve between the peak of landing impact forces acting to the feet and the landing impact time was very close as compared with that from ifself regression equation.

When exposed to a temperature shock of 41±0.2℃ for periods of 0.5 to 2.0 hours, the aquatic oligochaete, Limnodrilus hoffmeisteri, would shed its tail. The relationship between the rate of tail-cutting (TC) and the duration of temperature shock (t) can be expressed as TC=e~(2.44t-1.63). When the exposure period was limited to only 6 to 18 minutes then returned to 25℃ for 24 hours incubation, the rate of tail-cutting was still increased and died, both mature and immature worms.

When exposed to a temperature shock of 41±0.2℃ for periods of 0.5 to 2.0 hours, the aquatic oligochaete, Limnodrilus hoffmeisteri, would shed its tail. The relationship between the rate of tail-cutting (TC) and the duration of temperature shock (t) can be expressed as TC=e~(2.44t-1.63). When the exposure period was limited to only 6 to 18 minutes then returned to 25℃ for 24 hours incubation, the rate of tail-cutting was still increased and died, both mature and immature worms. The regression of mean mortality (Y) and shock duration (T) is Y_1=6.418T-28.116 and Y_2=4.895T+10.860 for mature and immature worms, respectively. The full effect of such extreme thermal shock is obviously lasting to worms returning to normal conditions.

在41±0.2℃热冲击下,水栖寡毛类霍夫水丝蚓(Limnodrilu hoffmeisteri)经0.5—2.0小时后其瞬时断尾率(TC)与时间(t)关系为TC=e~(2.44t-1.63)。冲击时间缩短至6—18分钟再将动物在25±0.5℃中培养24小时,成体与幼体断尾率随作用时间的延长而增加,最后大多死亡。成体死亡(y_1)与作用时间(T)的关系为y_1=6.418T-28.116;幼体死亡率(y_2)与作用时间(T)的关系为y_2=4.895T+10.860。热冲击显然延续到动物恢复至正常条件时尚起作用。
