And now the men say it's a sinking ship, and it's time they all got out. Doesn't it sound awful! But of course there's a lot as'll never go till they have to. They don't like these new fangled mines, such a depth, and all machinery to work them.

Results: a In the negative control group, spontaneous chromosome aberration and micronucleus rated the mice's were very low; in the positive control group, chromosome aberration and micronucleus rate of the mice's were highest. b Before cyclophosphamide intoxation, when the four kinds of vegetables and hilts juice were preventively irrigated into the mice's stomachs respectively, the chromosome aberration and micronucleus rate in the negative control group were lower than these in the positive control group (P.05); but after intoxation, when the four kinds of vegetables and fruits juice were therapeutically irrigated into the mice's stomachs respectively, the chromosome aberration and micronucleus rate were similar with the result above mentioned . c Acing the four kinds of vegetables and fruits, sea-buckthorn lad the best preventive and curative effects.

结果：a在阴性对照组中，小鼠自发的染色体畸变率和微核率极低；在阳性对照组中，小鼠染色体畸变率和微核率最高。b在环磷酰胺染毒之前，分别将4种蔬菜水果汁给小鼠进行预防性灌胃，其染色体畸变率和微核率均比阳性对照组低(P.05)；在染毒之后，分别将4种蔬菜水果给小鼠治疗性灌胃，其结果与上述实验结果相似。c在4种蔬菜水果中，以沙棘的预防和治疗效果为最好。

The thermoinduced coloration system of fluorane/iodonium salt has been investigated. The kinatic studies of thermoinduced color development reaction in polymer film was performed. It was found that two different phenomena appeared in the relationship between reaction rate constant and temperature. A very low value of k〓(0〓mol〓·l·s〓) and very high energy of activation E〓(149 KJ·mol〓) observed in the region of low temperature, whereas a larger value of k〓(1~10 mol〓·1·s〓) and smaller energy of activation (E〓33 KJ·mol〓) displayed in the region of high temperature of 150℃.

研究了荧烷/碘鎓盐热致显色反应体系，进行了分子膜中热生色反应动力学的研究，发现热生色速度常数k〓和温度关系呈现二种不同情况：在低温区，k〓值很小（＜10〓mol·1·s），活化能很大（E〓=149KJ·mol〓）；而在高温区，k〓值较大（1~10〓mol·1·s），活化能较低（E〓=33KJ·mol〓），它们的转折点位于温度（T〓=119℃），表明高于T〓是进行热致显色反应的重要条件；考虑到它们用作热记录介质的可能，研究了熔融状态中热生色反应。

Similar to the oxidation process of Si(111)-7×7 by water,the gradual insertion of S atom into Si_a-Si_s backbond is possible to occur,and the insertion pathway,which begins with directly destroying Si_a-Si_s backbonds by a foreign H_2S molecule,remains more favorable.However,when H_2S attacks at the Si_a site to split Si_a-Si_s backbond with its S or H atom,there is no distinct thermodynamical and kinetical difference between these two attacking behaviors,whereas Si_a-Si_s backbond is easilier broken when H_2O attacks at the Si_a site with its O atom.This mainly lies in the fact that the electronegativity of oxygen is larger than that of sulfur.

5类似于H_2O对Si(111)-7×7的氧化历程，S原子逐步插入Si_a-Si_s键是可以发生的，且H_2S直接打开Si_a-Si_s键进而使S原子插入的途径仍是动力学上较为有利的，但H_2S以S或H原子进攻Si_a位从而打开Si_a-Si_s键的两种反应机制在动力学和热力学上并没有表现出明显的差别，而当H_2O以O原子进攻Si_a位时，Si_a-Si_s键则较容易断裂，这应归因于O的电负性比S大。
