Thirty patients with acute promyelocytic leukemia were observed between September 1977 and October 1985. Bleeding diathesis with petechiae or ecchymosis (80%) was the most common presenting symptom. Seventeen of 24 patients with pretreated coagulation studies were diagnosed to have disseminated intravascular coagulation. Six out of 11 patients died from intracranial hemorrhage after a mean of 2.5 days of hospitalization without any treatment. DIC was responsible for death in most cases. Induction therapy with anthracycline and cytosine arabinoside combined with prophylactic heparin infusion was carried out in the remaining 19 patients. Two patients were incompletely treated. Eight out of 17 patients achieved complete remission after a mean of 63 days following chemotherapy. The remission rate was 47%.

The formation of secondary phase in the non-equilibrium peritectic reaction was observed by precise transmission electron microscopy analysis. The microstructural evolution and phase selection regularities under different solidification velocities were constructed from the laser resolidification experiments. A new phenomenon involving two-phase coupled growth was firstly detected in the rapidly solidified Ti-Al peritectic alloy. The Ti-45Al-2Cr-2Nb alloy with fully lamellar structure ( a 2+ g ) was taken as an object to investigate the possible preparation of bulky metastable g phase materials based on both adjusting the competing nucleation relation and changing the growth kinetics condition.

Main results are listed as below: 1. In rapid solidification, when the cooling rate is over some critical value, the solidification system will become unstable in the sense of the nonequilibrium thermodynamics, a uncontinuous steady state jump phenomenon will occur, and this uncontinuous steady state jump can be understood as the glass transition.

主要得到了如下结果：(1)通过对快速凝固过程的动力学及热力学的分析，提出了非晶转变的分枝理论模型，结果表明，对一合金熔体，当冷却速度大于某一临界值时，凝固体系会出现非平衡热力学意义上的失稳而出现多定态分枝现象，这一多定态现象可以被理解为非晶转变。
