Cancer is uv's final result.shortwave radiant energy,especially from the uv b band,breaks the strandsof dna.enzymeswork constantly trearrange the dna into proper sequence.but with repeated uv exposure,the repair process may even-tually break down.then the mutantdna may produce a colony of cancer cells.but skin cancer may be avoided with a good dose of common sense.people with fair skin and blue eyes who burn easily stand the highest risk.special danger spots are the parts of the body most constantly exposed to the sun,such as the cheeks,nose,lower lip and the ears.people who have already developed precancerouslesionsor had one skin-cancer growth stand a greatly increased chance of developing others.

紫外线伤害的最终结果就是诱发癌症。短波辐射能量，特别是来自uv-b波段的辐射能量会破坏dna链。本来，酶能够按照适当的顺序来重新安排这些被打乱秩序的dna，但是持续暴露于紫外线下会让这一修复过程崩溃。到那时，变异的dna就会制造出大量的癌细胞。其实，只要运用一些常识。我们就能预防皮肤癌。浅肤色、蓝眼睛的人会轻易就被晒黑，因此他们患皮肤癌的风险就高。诸如脸颊、鼻子、下嘴唇和耳朵等长期暴露在阳光下的部位是皮肤癌的高发区域。那些已经受到癌症前期伤害或者是已经患过一次皮肤癌的人，极有可能再次患上皮肤癌。

I scarce knew in what Manner to receive them; but found to draw our selves in a close Line was the only Way: so we form'd in a Moment: But that we might not have too much Interval, I order'd, that only every other Man should fire, and that the others who had not fir'd should stand ready to give them a second Volley immediately, if they continued to advance upon us, and that then those who had fir'd at first, should not pretend to load their Fusees again, but stand ready with every one a Pistol; for we were all arm'd with a Fusee, and a Pair of Pistols each Man; so we were by this Method able to fire six Volleys, half of us at a Time; however, at present we had no Necessity; for upon firing the first Volley, the Enemy made a full Stop, being terrify'd as well with the Noise, as with the Fire; four of them being shot into the Head, dropp'd, several others were wounded, and went bleeding off, as we could see by the Snow: I found they stopp'd, but did not immediately retreat; whereupon remembring that I had been told, that the fiercest Creatures were terrify'd at the Voice of a Man, I caus'd all our Company to hollow as loud as we could; and I found the Notion not altogether mistaken; for upon our Shout, they began to retire, and turn about; then I order'd a second Volley to be fir'd, in their Rear, which put them to the Gallop, and away they went to the Woods.

我简直不知道如何对付它们。结果，我认为最好的办法是我们互相靠拢，排成一行。于是，我们马上照此行事。为了不致使我们的火力中断太久，我下令只许一半人开枪，另一半人作好准备；如果第一排枪响过后，狼群继续向我们冲来，就开第二排枪；同时，在开第二排枪时，那开第一排枪的一半人，不要忙于装他们的长枪，而是应该抽出手枪，作好准备。因为我们每人身上都有一支长枪和两支手枪。用这种办法，我们可以连续开六排枪，每次有一半人开枪。然而，当时还没有必要这样做。放出第一排枪之后，我们的敌人就给枪声和火光吓坏了，马上停止了前进。有四条狼被我们打中头部，倒了下来；另外有几条受了伤，鲜血淋淋地跑掉了。这在雪地上可以看得一清二楚。我发现，狼群停止了攻击，但没有后退。这时，我忽然记起有人说过，就是最凶猛的野兽，听见人的声音也会害怕。于是我就叫大家拼命呐喊。这个办法果然很有效。我们一喊，狼群就开始后退，掉头跑掉了。我又下令朝它们背后开了一排枪。这样一来，它们才撒腿跑回树林里去了。

Larches of different ages have different net photosynthetic rate: the photosynthetic capacity of the young ones are bigger than that of the old ones; the stand density do not affect the net photosynthetic rate obviously; as far as the different stand classes are concerned, the diurnal changes of net photosynthetic rate is closely related to the photosynthetic active radiation. For the different layers of the crowns, there are greater ecological factors (illumination intensity, temperature, humidity etc.) on the upper layers than on the lower layers: the CO2 concentration of the lower layers is greater than that of the upper layers, which is indeed an exception; the net photosynthetic rate on the upper layers of the crown is generally greater than that of the lower layers. It showed that the CO2 concentration is not a main factor in the natural changing range of the CO2 concentration. Different directions of the crown have different photosynthetic active radiation, which is generally like exposed to the sun﹥North﹥in the shade of crown. However, the changes of net photosynthetic rate are not quite the same, which is North﹥exposed to the sun﹥in the shade of crown.

不同年龄的兴安落叶松净光合速率不同，年龄小的个体光合能力高于年龄大的个体；群团密度与净光合速率没有显著的相关关系；而对不同分级木，净光合速率日进程变化规律与光合有效辐射有着密切的联系；林内树冠不同层次各生态因子有上层大于下层的趋势，而CO2浓度在下层的含量高于上层，净光合速率上层普遍大于下层，说明在林内自然CO2浓度变幅内，CO2浓度不是主要因子；兴安落叶松树冠不同方向的光合有效辐射不同，一般向阳﹥北向﹥背阴，而净光合速率变化有北向﹥向阳﹥背阴的趋势。
