不相似

Leaves tufted; stipes 15-30 cm long, densely scaly at base, glabrous above; sterile lamina about 60 cm long and 20 cm wide, simply pinnate; pinnae numerous, alternate or subopposite, linear-lanceolate, the largest about 12 cm long and 1 cm wide, base cordate, apex acuminate, margin finely toothed; veins close, forking once or twice and forming areoles near the midrib; fertile lamina similar to sterile ones, but somewhat reduced, about 8 cm long and 0.4 cm wide, lower surface almost entirely covered with sporangia.

叶簇生；叶柄长15-30厘米，基部密被鳞片，向上近光滑；不育叶片长约60厘米，宽20厘米，一回羽状；羽片多数，互生或近对生，线状披针形，最长者长达12厘米，宽约1厘米，顶端长渐尖，基部心形，边缘有细密锯齿；叶脉1-2次分叉，近中脉形成网眼；能育叶与不育叶相似，但较小，长约8厘米，宽约0.4厘米，下部满布孢子囊。

In this exper iment,we took the advantage of RNAi technique,microinjected tinman and singless dsRNA into the early embryos in Drosophila respectively and got these two genes' RNAi phenotypes,which were very similar to that of their mutant,showing heart tube defects or no heart precursors formation.tinman dsRNA eve caused visceral mesoderm defects and the somatic muscles disruption,yet wingless dsRNA only affected heart precursors and had no effect on visceral mesoderm and somatic muscles,indicationg that the heart-related genes dsRNA interference worked effectively and exclusively in Drosophila.

实验运用RNAi技术，分别将tinman和wingless的dsRNA注入果蝇的早期胚胎，得到了这两个基因的dsRNA干扰表型，与两个基因的突变体表型非常相似，都表现为果蝇心脏前体细胞不能形成或心脏管缺失。尤其是tinman基因的dsRNA，还引起了肠中胚层缺失和体壁肌肉组织的紊乱，而wingless基因的dsRNA却只影响心脏的形成，而不影响肠中胚层，说明dsRNA干扰具有非常强的特异性，因而不失为研究果蝇心脏发育基因功能的有效方法。

马蒂斯"准确并非真实"的真实观与中国传统绘画中"似与不似"的真实观极为相似，但是马蒂斯的绘画是建立在对自然物象写生的基础上的，而中国传统绘画一般不强调对自然物象的直接写生，而是在渐渐离开对物象的观察之后比照和感受。

Spikelets pale yellowish, ovate to suborbicular, 1.5–1.8 mm, abruptly acute; upper glume hyaline, 2-veined with the veins marginal, ciliate along margins with long silky hairs; lower lemma similar but not ciliate; upper lemma pallid at maturity, ovate, as long as spikelet, crustaceous, obscurely striate.

The results suggested that compared with A-starch and maize starch, there are more quantities of impurities, such as protein, lipid and pentosan, in B-starch. B-starch prepared in the laboratory almost has the same compositions as three samplings, and accords with the reports of some documents too. Differing from the granules in A-starch, those in B-starch are smaller sized (1-10m)and oval shaped, and felted each other. The crystallogram of A- and B-starch are similar, i.e. A type. There is difference in granular distribution between A- and B-starch. The granular distribution of B-starch is anomalous and extensive (l~1259m).B-starch has bigger dilatancy and retrogradation, and smaller blue value, solubility, viscosity, gelatinization temperature and gelatinization enthalpy.

试验结果表明：跟玉米淀粉、A淀粉相比较，B淀粉含有的蛋白质、脂肪和戊聚糖等杂质数量多；实验室制备的小麦B淀粉中淀粉、粗蛋白、戊聚糖等含量均与文献的报道接近，也与在工厂采样的B淀粉相近；与A淀粉不同，B淀粉以小颗粒的淀粉为主，平均粒径1～10μm，颗粒形状呈椭圆形，同时颗粒和颗粒之间黏结紧密；B淀粉和A淀粉晶形结构相似，都为A型；B淀粉的粒度分布情况不同于A淀粉，其粒度分布规律性不强，分布范围也较宽，粒度在1～1259μm之间；B淀粉的凝沉值和膨润力大于A淀粉，而沉降体积、蓝值、溶解度、粘度、糊透光度、相变温度和热焓均小于A淀粉；杂质的含量对B淀粉性质的影响是明显的，随着杂质含量的增加，沉降体积、溶解度和透光度减小，膨润力增大，但是它们对凝沉值、蓝值和粘度的影响比较复杂。
