In conclusion, the control mechanism of beetle's elytron is quite complicated, and all the results of this thesis set up a basis for the further bionic design of structure and its optimization in the field of aviation and spaceflight.

总之，甲虫鞘翅间联接锁定机构的控制机理是相当复杂的，而这些研究成果对航空航天领域中的联接机构结构设计与优化有一定的仿生依据和重要价值。

Maize leaves have Kranz anatomy and show extreme cellular differentiation between bundle sheath and mesophyll cells, which have specialized metabolic roles.

玉米叶片的解剖和查看克兰兹极端细胞分化之间的维管束鞘和叶肉细胞，其中有专门的代谢作用。

Animals tests showed that sphingomyelin could inhibit the development of abnormal colon crypt and colon tumor or cancer of ICR MOUSE induced by 1,2-dimethylhydrazine, by contributing to the protein expression of PCNA and Connexin26 in the tumor or cancer tissue, so sphingomyelin was considered to have the function of preventing colon cancer.

动物实验研究发现鞘磷脂能通过影响肿瘤组织中PCNA和Connexin 26蛋白表达，抑制1，2－二甲肼诱导的ICR小鼠异常结肠隐窝和结肠肿瘤的发生，因此对结肠癌有一定的预防作用。

Radical leaves: stipules ovate, herbaceous, adnate to petiole; petiole sheathing at base; leaf blade imparipinnate; leaflets opposite, rarely alternate, broadly elliptic or obovate-oblong; cauline leaves few, with few leaflets, or simple and then margin 3-lobed or 2- or 3-serrate.

胚根叶：托叶卵形，草本，贴生于叶柄；叶柄具鞘的在基部；叶片奇数羽状；小叶对生，很少互生，宽椭圆形或倒卵形长圆形；很少的茎生叶，有很少传单，3浅裂的或单的然后空白边2或3使成锯齿波。

Many developing axons become myelinated by glial cells; this increase the speed of axonal conduction.

许多生长中的轴索变成有髓鞘的神经胶细胞，他能增加轴索传递的速度。

It is of important pathologic and clinical significance to classify the intratemporal facial nerve neurilemmomas into outgrowing and ingrowing types.

将颞骨内面神经鞘瘤分为内生性和外生性两种类型有重要的病理和临床意义，有助于手术目的的确定和手术方法的设计。

This is that people with a single copy of the gene for Tay-Sachs, or that for Gaucher's, or that for Niemann-Pick should be more intelligent than average.

不过，该理论也有令人信服的地方：它对于拥有单份泰萨二氏病或脑苷脂沉积病或神经鞘磷脂沉积病基因的人会比普通人更聪明做出了明确而可检验的预测。

Vaccinia virus belongs to the poxvirus family and has a double-stranded DNA genome of 192Kb in size. VV contains an envelope and replicates in cytoplasm of the infected cells. VV has a wide host range and infects various mammalian cell lines as well as animals.

牛痘病毒(Vaccinia virus， VV)属於痘病毒科中一拥有192kb双股DNA遗传物质的病毒，会在细胞质中繁殖出具有鞘膜的病毒，进而感染其他不同种的哺乳动物细胞和动物个体。

Culm sheaths tardily deciduous, straw-colored, white powdery and stiffly white hairy abaxially, distal margins with cilia 1–2 cm, base without a projection, apex truncate; auricles inconspicuous; oral setae many, 1–1.8 cm; ligule truncate, short, 1–1.5 mm, margin ciliate; blade reflexed, linear-lanceolate, more than 1/2 or 2/3 length of sheath, abaxially glabrous, apex acuminate.

分枝50(-100)缓慢落叶，稻草色，白色粉状和硬白色有毛的厘米竿箨，叶耳不明显；口头的刚毛很多，1-1.8厘米；叶舌削去，短，1-1.5毫米，边缘具缘毛；叶片反折，线状披针形，超过1/2的或2/3段鞘，背面无毛，先端渐尖。

BACKGROUND: Studies demonstrated that incisor continuously growing is due to lack of epithelial root sheath formation. However, researches regarding whether receptor activator of nuclear factor κB ligand and osteoclast has correlation with continue root development is poorly understood.

背景：研究表明小鼠不断生长的切牙是由于切牙仅有颈环而无上皮根鞘的形成，但是破骨细胞分化因子核因子κB受体活化剂配体和破骨细胞与不断生长的牙根发育是否相关，目前研究较少。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
