Camshaftless valve actuation includes electromagnetic,electrohydraulic,electropneumatic and electromechanical types.it could vary valve timing agilely,simplify the engine's structure,deactivate some of the engine's cylinders selectively and vary the effective compression ratio flexibly to adapt different fuels.So it could offer more advantages than general variable valve timing.

阐述了在发动机上以电磁、电液、电气或其他方式驱动气门，实现无凸轮轴气门驱动，可以灵活改变气门正时，简化发动机结构，能有选择地闭缸，灵活改变发动机有效压缩比以适应多种燃料要求，使发动机获得比采用一般可变气门驱动更多的好处。

In the fourth chapter, the effects of ultrasound on the direct electrosynthesis of solid K_2FeO_4 and the anodic behaviors of pure iron were investigated, and the physical properties of the samples were characterized by means of XRD, FTIR and SEM.

在第四章中，对超声波在14 mol／dm~3 KOH溶液中辅助直接电合成K_2FeO_4固体的影响作了研究，并采用扫描电子显微镜、X-射线衍射和傅立叶红外吸收光谱等技术对超声波作用和无超声波作用直接电合成的K_2FeO_4的表面形貌和结构进行了表征。

Scale emergence makes the parts relationship network becoming a scale-free network, and the emanative network whose local world is dense and other is sparse is changed gradually on the network structure.

标度涌现使零部件关系网络成为无标度网络，在结构上逐渐演变为局部密集、大部分稀疏的发散型网络。

General characteristics of cells, its chemical constituents ( protein, nucleic acid, carbohydrate, lipid), cell structure , cell cycle, cell division, four kinds of tissues (epithelial, connective, muscular, and nervous), organ, ten organ systems (dermal, skeletal, muscular, digestive, respiratory, circulatory, excretory, endosecretory, nervous, and reproductive).

细胞的一般特征，细胞的化学组成(蛋白质，核酸，糖类，脂类)，细胞的结构，细胞周期，细胞分裂(无丝分裂，有丝分裂，减数分裂)，四大组织(上皮组织，结缔组织，肌肉组织，神经组织)，器官，十大系统(皮肤系统、骨骼系统、肌肉系统、消化系统、呼吸系统、循环系统、排泄系统、内分泌系统、神经系统和生殖系统)。

This difference enables seeds to be classified as nonendospermic or endospermic.

可以凭借这种结构上的差别将种子分为有胚乳种子和无胚乳种子两类。

In the A and B figures, small grape-like tissue covered over all the epiglottic area that is hypertrophic lymphoid tonsil. More advanced the fiberoptic laryngoscope during spontaneous inspiration phase, larynx and vocal cord can be visualized in the C and D figures. We must emphasize that endotracheal intubation and even artificial ventilation was hardly performed under direct laryngocopy and general anesthesia.

图片A和B中，覆盖整个会厌部的葡萄息肉状物就是濔漫增生的舌底部淋巴组织增生，当光纤内视镜随著病人自主呼吸向内向下移动，吐气时可以见到图片C和D中喉头及声带的开合，由於在全身麻醉下无自主呼吸时此病人咽喉部位的似帘幕状遮蔽特殊结构造成之困难插管甚至是困难通气。

According to the special structure of the large visual field CCD camera used in moving target tacking, a new method based on adjusting the electronic shutter steplessly is proposed to get the high quality image. Through adjusting the exposal time in real time,we could make the light adjusting fast and accurately.

针对用于目标跟踪的大视场CCD相机的特殊结构，为了获得高质量图像，提出了一种基于电子快门无级调节的自动调光方法，即通过实时调整CCD相机的曝光时间来实现快速、高精度调光。

The milled powders with either ethanol or stearic acid as PCA remain a solid solution structure eyen after 12h milling, but both transform to FeAl (B2) intermetallic after subsequent vacuum annealing at 1100℃, during which more Al2O3 is formed in the ethanol milled powders.

两种粉末经12h球磨后，仍保持固溶体结构；经1100℃真空热处理后，两者均可转变为FeAl(B2)金属间化合物，但无水乙醇作PCA的球磨粉末中Al2O3生成量相对较多。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
