In this paper four non-spherical surface types have been chose, ellipsoid surface, parabolic surface, pointed arch surface and conical surface. Base on the best fineness ratio, four surfaces are modeled, and their properties are analyzed in detail.

本文选择椭球面、抛物面、尖拱面、圆锥面这四种非球面面型整流罩，在基于整流罩最优的长径比的基础下，对各种情况分别进行建模，并对其光学性能进行了详细分析。

Autotetraploids from diploidy leaves of Paulownia elongata on the double layer MS media supplemented with 0.1 mg/L NAA and 15 mg/L BA(optimal organogenetic medium to the leaves of diploidy seedlings) with different colchicines concentrations were induced,chromosome numbering of the plant root tip cells and DNA content analysis of the leaf single cell were used to analyse the autotetra ploids.

在含不同浓度秋水仙素的MS+0.1mg/L NAA+15mg/L BA双层培养基上进行兰考泡桐四倍体植株诱导试验，并通过变异植株根尖细胞染色体观察和叶片单细胞DNA含量测定进行倍性分析。

The results showed that the coefficient of raicel decreased firstly in a short distance, and then kept stable form radicel base to radicel apical.

通过对胚根分支系数研究表明：从根基部到根尖，呈现出先递减，然后保持稳定的趋势，采用经验分布函数表示；同时，用四种分支类型已能描述玉米胚根分支特征，且它们的特征参数在一定范围内随机分布。

The result showed that the plant of Maicao No. 9 was tall, with good fecundity, fully filled grain and vigorous growth. The chromosome number of the root cells was 2n=56, through the observation of pollen mother cells meiosis, there were a certain amount of univalents, ring bivalents and bar bivalents in PMCM. Different numbers of lagging chromosomes, chromosome bridges and micronucleus were found in anaphaseⅠ, anaphaseⅡ and tetraspore.

结果表明：麦草9号植株高大，结实性较好，籽粒饱满，生长旺盛；根尖细胞染色体数目为2n=56，对其进行花粉母细胞减数分裂观察，中期Ⅰ具有一定数量的单价体、环状二价体、棒状二价体；后期Ⅰ、后期Ⅱ与四分体时期都出现不同数量的落后染色体、染色体桥、微核等现象。

Moreover, tests were made with the above four culture media upon stem apex, leaves, blossom bud and lateral bud. The result shows that leaves grow best in the 1/10MS culture medium.

同时用四种培养基分别对茎尖、叶片、花芽和带侧芽的茎端作组织培养，得到叶片在 1 / 1 0MS培养基中生长状况良好。

Results Fifty-eight (93.5%) cases SVA were preoperatively discovered by echocardiography, while 2 (3.2%) misdiagnosed as tetralogy of Fallot and tricuspid regurgitation and 2 (3.2%) missed diagnosis.Accompanying teratisms included frequently ventricular septal defect (33 cases, 53.2 %) and aortic valve dysplasia(11 cases, 17.7%).The rupture site and the drainage chamber were essentially consisted with surgery,while the size of VSD measured by echocardiography was significantly smaller than that measured in operation.

结果 62例患者中，术前超声诊断Valsalva窦瘤破裂58例(符合率93.5%)，误诊为法洛四联症、三尖瓣反流各1例(3.2%)，漏诊2例(3.2%)；常见的合并畸形有干下室间隔缺损(33例，53.2%)、主动脉瓣发育不良伴重度主动脉瓣关闭不全(11例，17.7%)；超声报告窦瘤部位及破人腔室与手术结果一致，超声所测室间隔缺损大小明显低于手术所见。
