Leaves petiolate; leaf blade usually papery, secondary veins 2-4 on each side of midvein, tertiary veins parallel.

叶具叶柄纸质的叶片通常，次脉2-4在中脉两边各，平行的第三脉。

What we can conclude from the observation and seed-checking on morphic fectures of the treating group and comparison groups current generation and third generation is:apparent changes incurred to the leaf shape and the thickness of muskmelon when being treated by certain level of energy and dosage which can be inherited.

从各处理组与对照组当代和第三代苗期形态特征观察、考种中发现：在一定能量和剂量组合下，处理组香瓜叶型和果肉厚度发生了明显的变化，这种形态学变化是可遗传的。

After the selection from one to three generations, several mutants were obtained. The major mutants included non-nodule mutants (18 lines) which failed to nodulate after inoculated with rhizobia for two weeks, ineffective nodulation mutants (9 lines) which had less uneven and white or transparent nodules, an abnormal leaf and flower mutant which was dwarf without stipules, abnormal flowers and less nodules, and a slender mutant with a thin stem and smaller leaves.

从种植的三代植株中，筛选到多种共生固氮根瘤的突变体，其中不结根瘤突变体18个株系，表现为接种根瘤菌两周后无根瘤形成；结无效根瘤突变体9个株系，表现为根瘤数目少且分布不均匀，根瘤呈白色，有些为半透明；花叶形态异常突变体1个株系，表现为除根瘤数目少外，植株矮小、托叶消失、花形态异常；纤细突变体1个株系，表现为除根瘤数目少外，植株变小、茎细叶小。

The calculated results indicate that the energy bathers for the formation of dimethyl ether and trimethyl oxonium ion inside HSAPO-34 zeolite are 1.68 and 0.93 eV, respectively. The suggested intermediate oxonium ylide is very unstable and the energy barriers for the formation of C-C bond are over 3.0 eV by concerted pathway.

结果表明，二甲醚和三甲基氧鎓离子在HSAPO-34分子筛上的生成能垒分别为1.68和0.93eV，中间体氧鎓叶立德不能稳定存在，同时表明C-C键通过协同反应形成的能垒均超过3.0ev。

Mesoporous Ti02 is also synthesized with glycerol and pentaerythrite as temp-lates separately.It is characterized by TEM,XRD,BET and FTIR etc.

以多元醇类化合物结构相近的丙三醇，季戊四醇有机小分子化合物为模板剂制备出了中孔纳米二氧化钛粉体，对所得粉体进行了透射电镜，傅立叶红外，N2吸附一脱吸，粉末X一射线衍射等的测试。

This paper studies the quality of nutrition of three nutrition; That poor nutrition, nutrition, Eutrophication in constant temperature of 25 ° C under the conditions right to Potamogeton perfoliatus L germination of seeds and germination rate used, germination index and other indicators to Potamogeton perfoliatus L seed germination results were evaluated.

本文主要研究了三种营养化；即贫营养化、中营养化、富营养化在恒温25℃的条件下对穿叶眼子菜（Potamogeton perfoliatus L。）种子萌发的影响。

According to the result showed at 280nm and at 490nm,in the comparison of whether protein absorption top and sugar quantity top overlapped,glycoproteins would be detected preparatorily,and as a result,tubes in two distinct areas had glycoproteins by this method. Proteins were precipitated with trichloroaceticacid and with cold acetone,and glycoprotein was determined from SDS-gel.

再从各收集管的收集液中，用三氯乙酸沉淀蛋白法、冷丙酮沉淀蛋白法相结合浓缩、制备蛋白样品，进行SDS—PAGE，对SDS胶进行PAS糖链染色鉴定糖蛋白，并从茶树叶分级蛋白中准确地鉴定出两个区域的收集管中含有多种糖蛋白。

Methods Three-dimensional CT angiogram of 61 confirmed ruptured saccular aneurysms were analyzed.

方法对61个破裂动脉瘤的三维CT脑血管造影图像进行分析，测量动脉瘤的最大径，计算瘤体长与瘤颈宽之比，分析其形态特征，观察有无小泡样凸起和分叶状改变。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
