To some extent, the nucleate boiling and the two-phase forced convective heat transfer through the liquid film always co-exist in the saturated nucleate boiling zone and two-phase forced convection zone. The liquid fill-ratio, input power and content of the non-condensable gas exert significant influence upon the start-up performance and the heat transfer performance of LHP.

并且在饱和核态沸腾区与两相强制对流区内，总是在某种程度上同时发生着核态沸腾区与两相强制对流液膜传热；充液量、输入功率及其不凝性气体的含量对回路热管的起动性能和传热性能部有很大的影响。

Although these transitions are short, the equivalent resistance from the supply to ground is the average series combination of two switch-on resistors,both of which are considerably low in value.

The formula was established about calculating design parameters and technological parameters of ideal strip and bent strip in the period of forming. The thesis presented how to calculate the deformed area length and contact are radius of contact deforming between two elastic bodies on condition of the friction. The calculating formula of pinch force about plate-strip pinch mill was given and the results were analyzed that friction coefficient and radius of pinch rolls are very important for determining pinch force. Moreover, the rule of deforming and stress distribution of different 〓 ratio were gained on condition that the deforming was considered to be non-uniform distribution in the gap. The differential equations were got that calculate the displacements of large deflection of elastic cantilever rectangle plate with fixed end and the formula of the Finite Strip Method was conducted to study the regularity of mid-plane displacements, deformation and stresses for elastic-plastic large deflection bend of cantilever parallelogram plate with fixed or slidable end by integrating Prandtl-Reuss equation.

Using stereomicroscope, we observed the fracture line direction and location as well as the angle between the fracture line and the attrite plane. The data was compiled into statistics and analyzed. The results revealed that most of the vertical root fractures occurred in teeth with severe attrite crown and flat root. Numerous bucco-lingual oriented fractures occurred in the mesial root of molars, and we found three non-endodontically treated cases with mesio-distal oriented fractures in the palatal roots.

结果发现，两组的垂直牙根断裂均好发於牙冠严重磨耗（77.4-88.2%）且扁平的牙根（61.8-75.8%）上，以大臼齿的近心牙根发生率最高（64-85.7%），多为颊舌侧走向（91.2-91.9%），且於未根管治疗组别亦发现三例腭侧根断裂，走向为较宽的近远心方向，显示牙根断裂会沿著牙根较宽的方向发生；同时，未经根管治疗而产生垂直牙根断裂的牙齿具有根叉位置较低的现象（61.8%），牙根於比例上有较短小的特徵。
