The present article deals with the morphological and the anatomical observations on the mature sporophores in Ganoderma lucidum.The developmental morphology of the exochite and the basidiospores have been investigated,inter alia,in some de- tail.After investigating the effects of CO_2 gas on the sporophore culture the authors consider that when CO_2 content in the atmosphere is increased to 0.1% it promotes the growth of the stipe and inhibits the growth and differentiation of the pileus, and this is the main cause of the formation of the deformed sporophores.At the same time it has been observed that the deformed sporophores which did not give rise to pileus could produce pileus if CO_2 content in the atmosphere decreased.It is suggested that in the early stage of the sporophore culture,the CO_2 content in the atmosphere should be increased adequately in order to promote the growth of the stipe,in the later stage CO_2 content should be decreased by ventilation to induce the differentiation and growth of the pileus;thus disadvantageous factors may be con- verted into advantageous ones.The basidiospore germination has been obtained by the liquid culture with 10—20% sporophore extract.The germination percentage is about 8—15%.Thus,a new method for spawn rejuvenation is found.

本文对灵芝(G.lucidum)的成熟子实体作了形态解剖学观察,其中对皮壳及担孢子的发育形态作了比较深入的研究。在研究了子实体人工培养中空气中二氧化碳含量的影响后认为:当空气中二氧化碳含量增至0.1%时,有促进菌柄生长和抑制菌伞生长的作用。这是造成灵芝子实体畸形的主要原因。不发育菌伞的畸形子实体只要降低空气中二氧化碳含量,就能重新发育菌伞。建议在人工培养的初期适当提高空气中二氧化碳含量,以促进菌柄生长,后期通风换气有利于菌伞发育。这样就能转化不利因素为有利因素。对担孢子的研究表明,它能在10—20%的灵芝子实体水抽提液中萌发,频率为8—15%。为更新菌种找到了新的方法。

A kind of qranular structure was found in a high-strength low-alloy C-Mn steel containing V and Ti as rolled. Toughness of the steel fluctuates drastically in so far as it sometimes decreases to quite a low value with the appearance of this kind of structure.Some experiments with different rolling schdules have been carried out in order to observe the condition and the cause of formation for such a structure. As a result, a series of influencing factors have been found, such as temperature holding before finish rolling, finish rolling temperature, reductions and cooling rates. It is shown by experiments that a root cause of the formation of granular structure is that the steel with coarsened austenite grains has been overcooled to a great extent.The mechanism of the formation of granular structure has been also investigated. The granular structure is composed of two parts-the matrix and the "Islands". While the matrix is Widmanstatten ferrite, the "Island" is a product of transformation of which the carbonsegregated austenite is trapped between Widmanstatten ferrite and finally it transformed into Jmartensite for the increase in concentration of both C and Mn.In view of what has been stated above, a resonable controlled rolling schedule is suggested here such that a desired composite property of rather high strength and ductility can he attained to a level of a, =45 kg/mm2.

在含钒钛的低合金高强度碳锰钢的热轧状态组织中发现一种粒状组织。随着这种组织的出现,钢的冲击韧性发生很大波动,有时甚至下降到很低值。为了探明粒状组织形成的条件和原因,本工作进行了几种不同的轧制工艺试验。结果得出一系列影响因素,诸如终轧前的待温、终轧温度和变形量及冷却速度等。试验结果证明粒状组织产生的本质原因乃是具有粗化了的奥氏体晶粒的钢,受到某种程度的过冷所致。 本工作也研究了粒状组织形成机理,结果发现,粒状组织是由基体和“岛屿”两部分组成。基体是魏氏组织铁素体,而“岛屿”是被魏氏组织铁素体围挤在中间的富碳奥氏体的转变产物。 根据试验研究,提出了这种钢合理的控制轧制方案,能够保证得到高强度高塑性等预期综合机械性能。

At the joint formed by friction welding of dissimilar metals exists a "bonding zone" of a certain width. In this zone the "branches" grown up from the two dissimilar base metals are interleaved, forming thus an imbedded space-layer structure. The joint is given therefore with the nature of a "body bonding" instead of a simple "surface bonding", and so also superior characteristics of which a joint of "surface bonding" is not possessing. The causes of the formation of space-layer structure are: 1....

At the joint formed by friction welding of dissimilar metals exists a "bonding zone" of a certain width. In this zone the "branches" grown up from the two dissimilar base metals are interleaved, forming thus an imbedded space-layer structure. The joint is given therefore with the nature of a "body bonding" instead of a simple "surface bonding", and so also superior characteristics of which a joint of "surface bonding" is not possessing. The causes of the formation of space-layer structure are: 1. The shifting of the highest temperature surface and the main frictional beat generating surface away from the contact surface due to the difference in the thermophysical properties of the two metals. 2. The deformation of incidental rise and fall on the contact surface in the process of rotational rubbing under pressure. Evidences show that this phenomenon takes place in welding of similar metals as wel1.

试验得出异种金属摩擦焊接头处存在着一个具有一定宽度的“结合区”。在这个区域中,从两种金属基体上所生长出来的“树枝”相互穿插,形成一个镶嵌型的空间层状结构。这种空间层状结构的存在使接头具有“体结合”的性质,而不是简单的“面结合”,使接头具有一般“面结合”接头所不具备的特点。这种空间层状结构产生的原因是:(1)两种金属热物理性能的不同,引起最高温度面及主要摩擦发热面偏离接触面;(2)加压旋转过程中接触面上偶然性的高低起伏不断的演变。事实证明,在同种金属摩擦焊接头中也有这种现象存在。
