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 this thesis, firstly, some main models have been checked on their accuracy, and the reliability of MACORS code has been verified by the RELAP5/MOD2 code on five transient conditions for QSNP: loss of flow; loss of offsite power; incontrollable control rod withdrawal; the feed-water temperature increasing and the feed-water lost. The results obtained are very satisfactory. Secondly, MACORS is used to calculate the operating and accident transients for QSNP, and the analysis results are significant to real engineering. And finally for MNRS, MACORS is used to simulate the steady-state natural circulation heat-removed capacity and the transient behaviors from forced circulation to natural circulation. Some important conclusions are obtained by the analysis results.

本论文首先从各方面对核动力系统中最主要的、热工水力特性最复杂的反应堆和蒸汽发生器进行单独验证和理论分析，其次分别利用RELAP5/MOD2程序和MACORS程序对秦山核电站的双环路失流、全厂断电、反应性事故引入、主给水参数变化及丧失主给水五种瞬态工况进行了计算，结果符合很好，从而证明了本程序模型的准确合理性，选择数值方法的有效性和编制程序的正确性；尔后，利用MACORS程序对秦山核电站的多种运行及事故瞬态进行了分析，得出了具有工程价值的结论；对船用核动力装置的稳态自然循环载热能力以及相应参数的特性、强迫循环与自然循环的过渡工况等进行了仿真分析，所得结论对我国核动力船舶的设计，运行以及安全审评具有重要的意义。

Although natural selection likely equipped individuals with many ways of coping with threats in the family, choice of strategy is thought to hinge on how interparental conict ts into the broader family ecology.

虽然自然选择可能配备了与家庭的威胁，应对的战略选择多种方式的个人被认为是取决于冲突如何interparental安装到更广泛的家庭生态。

The effects of several components in the culture medium on Lithospermum erythrorhizon cell growth and secondary metabolite synthesis were studied, as well as structural dynamic model. The two-liquid-phase culture of Lithospermum erythrorhizon was carried out by choosing the proper organic solvent as the second phase. The bioactive carrier for adsorption was prepared and the condition of cell immobilization was determined. We combined the technique of two-liquid-phase culture and immobilization to carry out the culture. We chose the suitable type of reactor, studied its characteristics and results of cell culture using this reactor. The fed-batch operation was also studied on the basis of twoliquid-phase culture and immobilization used in culture in the reactor.

本文研究了紫草细胞悬浮培养中培养基中多种成分对细胞生长与次生代谢产物合成的影响，进行了结构化的动力学模型研究；通过选择合适的有机溶剂对紫草细胞进行了双液相培养研究；通过确定以吸附为细胞的固定化方法，进行了生物活性吸附载体的制备与固定化细胞的制备研究；并结合双液相培养技术，对紫草细胞进行了固定化培养及其动力学模型的研究；对反应器进行选型，并进行冷模与热模研究；在反应器中进行了固定化紫草细胞的双液相培养条件下的流加操作研究。

"The recognition of chest wall involvement preoperatively is important for staging and surgical planning," Dr. William Lunn, of Baylor College of Medicine, Houston, Texas, and colleagues write."Multiple modalities are available to assess the chest wall involvement preoperatively, including CT scanning, MRI, and ultrasound examination."

&术前识别是否有胸壁累及对肿瘤分期和手术方案选择很重要，&得克萨斯州休斯敦贝勒医学院的William Lunn医生及其同事写道，&评估术前是否有肿瘤胸壁累及有多种方法可用，包括CT扫描、MRI和超声检查。&

And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.

铁刀木的各个部位都作药用，资源量大的树叶和心材使用最多，并且现有的研究成果表明它们具有多种活性成分，针对现代人常患的失眠、焦虑等疾病具有较好疗效。4）通过收获法拟合的生物量回归模型对推测西双版纳地区铁刀木林薪柴蓄积量有较高的参考价值，砍伐3年后的六个样方中铁刀木的平均生物量为62.878 t.hm-2，高于5年林龄的热带次生林（16.35t·hm-2），对西双版纳热带雨林的保护有着重要意义。5）几个村寨最主要的薪材树种热值研究结果变异系数仅为1.1％，各薪材树种之间热值相差不大，铁刀木被选择为传统薪炭林更多是因为材质坚硬、收获运输方便、燃烧完全等特点。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
