板条

For the heat input of 8kJ/cm and preheated temperature of 60℃, impact toughness value of specimen was highest for the formation of fine grains and a certain quantity of granular bainite which can effectively partite lath bainite.

当采用8kJ/cm的线能量和60℃的预热温度时，粗晶区的晶粒较细，组织由板条贝氏体和一定量的粒状贝氏体组成，由于粒状贝氏体对板条贝氏体的分割作用，使板条贝氏体的长度较小，方向性差，表现的韧性最优越。

Observation of transmission electron microscope reveals that the f＇me structure of CGHAZ and IRCGHAZ of both in- service welding and routine is ferrite laths and the second phase particles that distribute on or between ferrite laths.

透射电镜下，在役焊接和常规焊接的粗晶区与临界粗晶区的主要形貌都是铁素体板条和分布在板条之间或板条基体上的岛状物，铁素体板条的亚结构都是高密度位错。

The struetural constitution of lath martendsite is composed of bundles of parallel jaths with varying sizes,stuffing martensite in irregular shape stuffed among laths at the boundary and corner of the pack- ets and retained austenitie thin film or platelet l...

板条马氏体组织是由一簇簇平行排列的大小板条，以及填充在马氏体板条间，束界和界隅内的不定外形的填塞马氏体和条间残余奥氏体薄膜或膜片所构成。

Moreover, its microstructural characters possess several configurations under TEM, which are (1) ferrite laths with obvious interface,(2) ferrite laths without obvious interface, but the interface can be discerned faintly from the linear arrangment of those directional islands,(3) the coexistence of ferrite laths and non--equiaxed grains. These are somewhat different from those of weld structures, which are generally thought to consist of an assemblage of interwoven ferrite laths.

管线用针状铁素体钢热轧板材中有明显界面的板条束或针状片条束；没有明显界面的板条束或针状片条束，可根据条状物或岛状物的有方向性的线状分布依稀辨别界面的存在；板条或针状片条与非等轴晶共存等多种不同形态，并不象焊接组织那样通常是单一的针状片条束或板条束形态。

The result proves that the thermal lensing effect of slab has been improved due to adoptation of adiabatic construction.

板条热透镜效应实验结果表明，在500Hz重复频率下，未装绝热结构的板条热焦距为0.78m，而装有绝热结构的板条的热焦距为1.93m，热聚焦大为改善。

In view of easy fusion flaw between connecting of doubler strake and deck plating or bottom plating strengthened, this paper puts forward a fire-new welding technics for the purpose to improve the technics of welding connecting of doubler strake. Under the help of this way, connecting of doubler strake can be penetratingly fillet welded, but not fuse with deck plating or bottom plating strengthened, at the same time the figure of weld surface can also be managed for increasing fatigue strength of connecting.

本文针对复板条对接接头容易和被加强的甲板或船底板发生粘连的缺点，从改善复板条对接接头的工艺入手，提出了新的焊接工艺，使得复板条对接接头既能保证完全焊透，又不会和被加强的甲板或船底板发生粘连，同时对焊缝表面形状进行处理，以提高接头的疲劳强度。

But it has some shortcomings. Connecting weld of doubler strake is directly welded on plating strengthened, in this way welding fluid fuse with plating strengthened such as deck plating or bottom plating, and then connecting of doubler strake fuse with deck plating or bottom plating strengthen. So breakage like crack of connecting of doubler strake may immediately destroy deck plating or bottom plating strengthened, which became of navigational accident.

但是，增设复板条来提高船舶总纵强度的方法有其缺点，每段复板条之间的对接焊缝是直接在被加强的板上施焊，焊缝就会溶入被加强的甲板或船底板，使得复板条对接接头与被加强的甲板或船底板发生粘连，这样，复板条对接接头的开裂等破坏就会直接引起船舶被加强的甲板或船底板的破坏，从而导致海难事故。

In this paper, thermal edffect in slab laser and parasitic oscillation in amplifier are analysized.Using the same method, we also calculate thermal effect in photonic crystal fibers with hollow claddings.
