So the suggestions of the concrete and mortar to be tested after 7 days and the epoxy resin mortar to be tested after 3 days are given 因此,对混凝土?水泥砂浆建议在7天龄期后进行测试,对环氧树脂砂浆建议在3天龄期后进行试验。

On the basis of spot sample and laboratory experiment , authors studied the time - variant probability model early age period mechanical properties of high - strength concrete 通过现场试验建立了高强度混凝土早龄期力学性能的经时概率模型。
Many beating experiments of different quality of added lime and unlimited compress strength experiments of different time have been made 为了研究掺石灰对膨胀土的影响，进行了不同掺灰率的击实试验和不同龄期的石灰土无侧限抗压强度试验。
Comparing the dynamic modulus of elasticity of the model in each age with the corresponding values of the test data , we can verified the feasibility of the method 将求得的各龄期的动态弹性模量与相应的试验数据相比较，验证方法的可行性。
This paper also states initially that the powder influence upon the workability of fresh concrete and mechanical property of hardening concrete 不同配比、不同水化龄期的试样显著结构表明：高钛矿渣增强的机理主要是微粉的填充效应和胶凝效应。
In order to meet the need of production in practice , the proper molding water content , pressure and curing age were determined by experiment and analysis 结合现场的生产要求，通过大量实验与分析，给出了合理的成型加水量、成型压力和养护龄期。
Many beating experiments of different quantity of added lime and unlimited compress strength experiments of different protective time have been made 为了研究掺石灰对膨胀土的影响，进行了不同掺灰率的击实试验和不同龄期的石灰土无侧限抗压强度试验。
The effect order of them on the compressive strength was cement / aggregate ratio , fly ash / cement ratio and ages , but they were all not notable effect 各因素对粉煤灰混合料抗压强度的影响程度按自大到小的顺序依次为胶沙比、灰胶比和龄期，但均无显著影响。
The parasitized dbm larvae had prolonged their 4th instar duration obviously , and the later the larva had been parasitized , the longer this extended duration became 小菜蛾幼虫被寄生后，其4龄发育历期较未被寄生的显著长，且寄生时龄期越大4龄历期延长越多。
