Result The results showed that tissue culture seedlings cultured with disinfection seeds and fresh fruit seeds had higher survival rates, which could reached above 75.0%. Taken Pingguoli and Xiangshuili for cions, Shanli without root for rootstock, the survival rate of graft seedlings had obvious difference. And Xiangshuili for cions had higher survival rates. Taken Xiangshuili for cions, Shanli and Xiangshuili for rootstock, the survival rate of graft seedlings with root had higher survival rates than that without root. Added hormone to the media could improve the survival rate of micro-grafting plants, in the medium of MS+BA 1.0 mg/L+IBA 0.3 mg/L, the survival rate reached 86.7%.

结果］种子消毒处理及鲜果取种组培苗的成活率均较高，达75.0%以上；以香水梨和苹果梨为接穗，无根山梨为砧木时的嫁接苗成活率有显著差异，其中以香水梨为接穗的成活率较高；以香水梨为接穗，山梨和香水梨为砧木时，带根的材料嫁接时的成活率都显著高于无根嫁接苗的成活率；此外，添加植物生长调节物质可以有效提高嫁接成活率，在培养基MS+BA 1.0 mg/L+IBA 0.3 mg/L中嫁接苗的成活率最高，达86.7%。

目的 ：了解成都市 1990～ 2 0 0 0年慢性非传染性疾病发病率的变化趋势，为慢性非传染性疾病的有效干预提供科学的数据。方法：采用 EXCEL、 SAS统计分析 1990～ 2 0 0 0年慢性非传染性疾病监测数据。结果：该市 3种慢性非传染性疾病(恶性肿瘤、脑卒中、缺血性心脏病)发病率呈上升趋势，且男性高于女性，其中恶性肿瘤发病率最高，脑卒中增长最快，恶性肿瘤中以肺癌发病率最高。糖尿病发病率女性高于男性。结论：成都市慢性非传染性疾病发病率正呈上升趋势，必须加强预防控制

The controlling factor of the polymerization rate is varied from the diffusion rate of monomers to the addition rate. In this case, the variation of polymerization rate is very small, and is close to first-order reaction.

控制聚合速率的主要因素则从单体的扩散速率过渡到单体的滴加速率，而聚合速率几乎不随时间变化、接近一级状态。

The flow-field around a hemisphere and a flat-nosed cylinder in the shock tube is simulated numerically by using non-equilibrium Navier-Stokes equations with an air chemical model of 5 species 17 reactions, and the catalytic rate constant of surface materials such as Pt, SIC:, Ni and a flight vehicle materials is determined by using the heat transfer rate of testing in the shock tube and the distribution of heat transfer rate along with the catalytic rate constants.

用5组分17个化学反应Durm-Kang空气化学模型和轴对称热化学非平衡Navier-Stokes方程，对激波管中球头和平头圆柱模型绕流流场进行了数值模拟，给出了驻点热流随催化速率常数变化的分布，并根据激波管实验测量的热流值确定了表面材料Pt、SiO2、Ni和某种飞船材料的催化速率常数，建立了数值分析高焓流动边界层催化特性的软件。

If selects in the research the base period is different, for example some people take the high bloating year as the base periods, some people take the low bloating year as the base periods, has take the nominal exchange rate big adjustment before as the base period, has depreciates after year take the standard currency as the base period, finally obtains the balanced actual exchange rate difference extremely is big, causes one person to have a judgment exchange rate detuning standard, has like this lost the balanced exchange rate research significance.

如果在研究中选取的基期不同，例如有人以高通胀年为基期，有人以低通胀年为基期，有以名义汇率大调整前为基期，有以本币贬值后的年份为基期，最后得到的均衡实际汇率差异就非常大，导致一人有一个判断汇率失调的标准，这样就失去了均衡汇率研究的意义。
