The lithologic characters changed from fluviolacustrine sandstone to aeolian Red Clay with thin interval of greyish-white sand layers at the depth of 602 m. It can be inferred from the rock strata and age that the development age of aeolian sequence in Lanzhou area was 7 Ma at least, which is in accordance with the bottom age (7~8 Ma) of the aeolian sequence of the eastern and central Loess Plateau, suggesting that their accumulation processes are unitary.

皋兰山剖面深度602 m处出现由河湖相砂岩向以风成红粘土为主常夹有薄层砂岩的地层转变，通过岩性地层及年代的推断，兰州地区的风尘序列堆积发育的年代至少为7 Ma，与黄土高原风尘序列堆积底界8～7 Ma基本一致，说明了兰州地区与黄土高原在风尘序列堆积过程中具有统一性。

Dynamic analysis of phase transition and observation of morphologic evolution show that the growth of K_2Ti_6O_(13) whisker is quite sensitive to calcination temperature accompanying with fulminous growth at given temperature, but after that the growth became slow.

动态相变分析和晶须形态演化观察表明：K_2Ti_6O_(13)晶须的生长对煅烧温度极为敏感，一定温度下晶须的生长转变几乎是&爆发式的&，但是此后晶须的生长变得很缓慢。

The results show that Be addition can effectively lower the eutectoid temperature of the hypoeutectoid Cu-Al alloy, but has no effect for the order-disorder transition.

实验结果显示，铍含量可有效降低Cu-Al亚共析合金之共析温度，扩大β单相区；而铍含量对序化结构转变温度并无明显影响。

With the addition of Al of about 1 wt%, the proeutectoid cementites were restrained during equilibrium transformation and dynamic phase transformation, the stability of undercooled austenite during deformation was increased, retarding the formation of pearlite and the interlamellar spacing of pearlite was decreased.

Al的加入使动态相变过程中奥氏体的稳定性提高、珠光体转变推迟，进一步细化了珠光体片层间距。

The microstructure of the steel isothermally treated at 950℃ were quantitatively analyzed and compared to the simulating results by Dictra software.
