To introduce perturbation corrections of lattice strain intosemiempirical MO calculations,we have written out the programs,STRAIN+SPHF,for calculating perturbation corrections of lattice strain,based onsemiempirical MO calculation program package MOPAC3.0.In principle,the theoretical method and program for calculating corrections of latticestrain can be employed for the studies of growth mechanisms for diamondfilms or other non-metallic films on any non-metallic heterogenic substrates.

运用引入晶格应变修正的AM1半经验分子轨道方法和不包含该修正的AM1方法，通过在Si(100)和(111)衬底表面上提取H原子以及CH3和C2H2吸附过程的计算比较研究，发现包含应变修正的结果比不包含该修正的结果更准确地描述了Si衬底上发生的化学反应过程，并且还能够揭示出无应变修正结果中没有揭示出的表面物理化学现象。

The results showed that the optimized content of Mg~(2+) was 5mmol/L; dNTP was 200μmol/L; Primer was 0.5μmol/L; Taq polymerase was lU/50ul in the PCR system. Only one fragment of about 270bp was amplified within the genome of 12 wild species and 23 cultivars of Mallus Mill., which indicated that Ty1-copia-like retrotransposons were archaic components of apple genome. The nested insertion of near and within the reverse transcriptase gene of Ty1-copia-like retrotransposons wasn\'t found in apple genome.2 The reverse transcriptase conservative region of Ty1-copia-like retrotransposons were amplified from Gala apple using the optimized PCR system. The amplification product was isolated, cloned and sequenced. Forty-five clones containing reverse transcriptase conservative region were obtained (accession number: AY849580 -AY849592 and DQ105035-DQ105066). Cluster analysis of these sequences showed a great heterogeneity among RT domains isolated from the same genotype.

从苹果属12个野生种和苹果23个栽培品种中都扩增到了约270bp的目的产物，且所有试材的扩增结果一致，均无目的条带以外的产物扩增，说明Ty1-copia类逆转座子在苹果属植物中广泛存在，且存在历史可能较为久远；从扩增结果看不出该逆转座子的逆转录酶基因或附近区域在苹果基因组内有嵌套行为的发生。2、利用优化了的PCR方法从嘎拉苹果基因组克隆了45条Ty1-copia类逆转座子逆转录酶保守序列(登陆号分别为AY849580-AY849592和DQ105035-DQ105066)，结果表明，同一基因组来源的这些序列存在高度的异质性。

Based on the newly proposed nomograph, patients both with obstructed and unobstructed cases can be diagnosed accurately. Also, those patients with weak detrusor, where the bladder can not provide enough power to micturate regularly, can also be identified with this new nomograph, which again can not be diagnosed with the Abrams-Griffiths nomogram.

根据我们计算和实验的结果，我们得知在没有阻塞的尿道流场内，摩擦损失是影响压力损失最主要的因素；而在轻微阻塞的尿道流场内，磨差损失及阻塞段几何外型改变，面积改变的能量损失都影响很大；而在较为严重的阻塞情况下，阻塞段的外型，最小截面积等影响能量损失甚为巨大，另外我们根据计算的结果发展出一个无因次参数图，我们选用了Reynolds number和来做参数，结果发现这样不仅可以把阻塞和未阻塞的病例分清，甚至能判断逼尿肌无力等症状。

The revesional mutation of TA100 colony was 2.55, 2.81, 5.36 without S9, and 1.73, 2.86, 4.14 with S9, respectively. Reversional mutation rate of TA98 colony exposed to 1.00L/dish extracts from Jiangjunyan with S9 was 2.22, and there was a dose-response relationship in reversional colony count. Ames tests of the other extracts were negative.
