By analyzing the characteristic features of the variations of temperature in the workpiece surface layer during grinding and the thermal inertia of the thermocouple, this paper reviews the reliability of the method recommended by Koya Takazawa of the dynamic temperature measurement by means of the single-wire thermocouple, and presents a method by which the dynamic response ability the instrument for temperature measurement should possess may be approximately evaluated according to the grinding conditions. On the basis of these discussions are given the experimental results of the grinding forces and the temperature distributions in the ground surface layer during surface grinding of the titanium alloy (Ti-6AI-4V) and the carbon steel(45°).Aoeording to the experimental results quantitative comparison and analysis are made in several respects of the grindability of titanium alloys and carbon steels. This shows that the peak temperature on the workpiece surface of titanium alloys is not much higher than that of carbon steels under the grinding conditions of this experiment,while the grinding ratio of Ti-6Al-4V is only about 1/45 that of 45# steel. The grinding chips of titanium considerably adhere to the abrasive cutting edges. From the experimental results, we find that, the main reason titanium alloys are hard to grind is not the high temperatures existing in grinding area,but the drastic chemical affinity of titanium alloys for, abrasive materials. Therefore, an intensive research, which seems to be the key to the fundamental improvement of the grindability of titanium alloys, should be carried on for the mechanism of the chemical affinity and for the inhibition of as much affinity as possible by selecting the best type of abrasive materials, and the suitable grinding fluid, and the optimal grinding speed.Attached to the end of this paper is a general computing programe for regression analysis of the experimental data, applicable to metal cutting experiments.

本文通过分析磨削时工件表层温度的变化规律以及热电偶的动态响应能力,对高泽所推荐的单丝热电偶动态测温方案的可靠性进行了论证,并在此基础上提供了有关平磨钛合金与45~#钢时的磨削力与工件表层内部温度分布的实测数据。文章在根据实测结果对钛合金与45~#钢的磨削性的几个方面定量地进行了综合分析以后指出,在实验所采用的磨削条件下,钛合金试件表面峰值温度与45~#钢相比偏高并不明显。但是两者磨削比却相差近45倍。此情况说明通常推测的磨削区高温并非TC—4难磨的根源,钛合金难磨的本质原因是它与磨料之间的激烈的化学亲和作用。因此深入研究这种化学亲和的机理,通过优选新型磨料、磨削液以及最佳磨削速度尽可能地去抑制这种化学亲和作用,应该是从根本上改善钛合金磨削性的关键。

The lung toxicities of bleomycins A_5 and A_2 in the mouse were studied with electron microscopy. The initial site of drug induced damage appeared to lie chiefly in the endothelium of the capillaries in the alveolar walls. The endothelial cell changes consisted of marked increase in the number of pinocytotic vesicules, appearance of vacuoles, formation of pseudopodia-like protrusions and fragmentation of the cell body. Blood platelets were frequently seen to adhere to the endothelial surface of the endothelium...

The lung toxicities of bleomycins A_5 and A_2 in the mouse were studied with electron microscopy. The initial site of drug induced damage appeared to lie chiefly in the endothelium of the capillaries in the alveolar walls. The endothelial cell changes consisted of marked increase in the number of pinocytotic vesicules, appearance of vacuoles, formation of pseudopodia-like protrusions and fragmentation of the cell body. Blood platelets were frequently seen to adhere to the endothelial surface of the endothelium and at times clump together forming microthrombi. For quantitative comparison of the damages elicited by A_5 and A_2, fifty capillaries from each animal treated with either component were examined and the percentage of injured capillaries was calculated for each group. It was found that higher percentages of injured capillaries occurred in the lungs of the mice treated with A_2 than those treated with A_5. As it is known that lung toxicity is the most severe side effect of bleomycin and that bleomycin A_2 is the main component in the bleomycin complex which is now available for clinical use, the observation that bleomycin A_5 is less toxic for the mouse lung while displaying approximately the same therapeutic effect in experimental animals as compared with A_2 suggests that further investigations on bleomycin A_5 as an antitumor agent might be desirable.

用电子显微镜观察争光霉素A_5和A_2对小鼠肺的损害作用。除观察形态变化外,还使用病变毛细管计数的方法比较了A_5和A_2引起肺病变的轻重程度。结果表明,A_5引起的肺病变明显的较A_2为轻。目前,国外临床使用的博莱霉素是以A_2为主要组分的复合物,肺毒性是它的主要毒副作用。A_5的肺病变较A_2轻,这一结果提示了争光霉素A_5临床肺毒性较低的可能性,值得深入研究。

In this paper,based on the concept of the degree of approaching for normal fuzzy sets, the conventional evaluation of earthquake intensity is studied and treated quantitatively. The literatures and reports in more than ten aspects have been collected. About seven hundred data have been sorted out. Setting the condition of building damage as an index, the quantitative comparison table from degree VI to degree XI has been compiled preliminarily, and, as an example, five poin s of Songpan-Pingwu Earthquake in 1976(M = 7.2) are checked interna 1y. Two points among the five are corrected slightly, while the rest are approved affirmatively. This is in conformity with the actual cond tions. Besides, the general method of evaluating the earthquake intensity by using fuzzy mathematics is discussed providing the possibility of quantitative treatment by computer for empirical judging the earthquake intensity.It is considered that the prospect for using the technique of fuzzy mathematics in engineering seismology is captivating.

本文用模糊正态集贴近度的概念,对现存的烈度评定作了定量处理。文中收集了十余方面的文献和报告,整理了约七百个数据,初步编制了从Ⅵ度到Ⅺ度的以房屋破坏为指标的定量对照表,并以1976年松潘平武地震为例,对它的五个点作了内检。文中对其中的两个点提出了不大的修正,对其余三个点作了肯定。与实际情况颇为符合。文中还阐述了用模糊数学方法进行烈度评定的一般考虑,提出了计算方法,为对经验性的烈度评定用计算机作定量处理提供了可能。
