本文研究了聚醋酸乙烯乳液的掺入量、养护条件、水灰比等因素对聚醋酸乙烯水泥砂浆性质的影响,以及砂浆的抗水性能。试验结果表明,聚醋酸乙烯乳液的掺入量以占水泥的的15%(以干科计算)左右最好,砂浆的抗折强度可提高一倍以上,抗压强度可增加8%左右。聚醋酸乙烯水泥砂浆的养护条件与普通水泥砂浆的要求不同,它应在较低相对湿度和较高温度下养护,才能充分发挥其强度。聚醋酸乙烯水泥砂浆的强度随水灰此减小而增加。聚醋酸乙烯水泥砂浆的抗水性较素水泥砂浆小很多。为了提高聚醋酸乙烯水泥砂浆的抗水性,采用了十余种不同的聚醋酸乙烯共聚物乳液进行了试验。试验结果表明,以丙烯酸丁酯醋酸乙烯共聚物代替聚醋酸乙烯可以使砂浆的抗水性大大提高,同时共聚物中丙烯酸丁脂的含量以5%为最佳。

Supersonic speed aircraft and guided aircraft missiles are subjected to rapid aerodynamic heating and rapid loading during their flight. For taking full advantage of the strength of structural materials in design, it is necessary to study the mechanical characteristics of metallic structural materials under rapid loading and heating. This paper describes a short-time high-temperature tensile testing machine, which is capable of constant-rate loading up to 85 kg/sec and heating at a rate up to 80℃/sec, the temperature gradient within the gage length for a distance of 50 mm being less than 5℃. All the heating, temperature-controlling and stress-strain measuring processes are done automatically. Experiments such as rapid tension under high temperature, rapid heating under constant loading and short-time creep can be carried out on this tester. Specimens of low carbon steel, R1T and 12F2A have been tested on it. Diagrams and tables have been included here and results from these tests have been preliminarily discussed.

高速飞机及飞航导弹在飞行过程中受到气动力的快速加热和快速加载.为了最充分地利用结构材料强度进行合理设计,必须研究金属结构材料在快速加载、快速加热下的力学性能.本文叙述了一种短时高温拉伸试验设备;这设备能以小于85 kg/s的速率对试件进行恒速加载,以小于80℃/s的速率进行快速升温;试件50mm标距内温度梯度小于5℃;整个加热控温过程和应力应变测量记录过程均系自动进行.在此设备上可进行高温快速拉伸和短时蠕变等实验,并已进行了低碳钢,等材料的短时拉伸、短时蠕变、恒裁等加热率的实验.文内列有图表,并对结果进行了初步讨论.

It is believed that the isolated ox pericardium may well be a good material for making artificial valve. Its mechanical behaviours, such as relaxation, hysteresis and non-linearity of elasticity modulus, are similar to those of some living tissues during mechanical test. If so, it can also be regarded as viscoelastic. An adequate amount of data useful for bioengineering has been obtained from one- and two-dimensional tensile tests for fresh pericardia of oxen and those fixed by glu-taraldehyde.
