有薄层的

It was wholly in the lower ice, but close against the upper, and was flattish, or perhaps slightly lenticular, with a rounded edge, a quarter of an inch deep by four inches in diameter; and I was surprised to find that directly under the bubble the ice was melted with great regularity in the form of a saucer reversed, to the height of five eighths of an inch in the middle, leaving a thin partition there between the water and the bubble, hardly an eighth of an inch thick; and in many places the small bubbles in this partition had burst out downward,and probably there was no ice at all under the largest bubbles,which were a foot in diameter.

在气泡之下和周围已经结了一层新的冰，所以气泡是在两片冰的中间；它全部是在下层中间的，却又贴近上层，扁平的，也许有点像扁豆形，圆边，深四分之一英寸，直径四英寸；我惊奇地发现，就在气泡的下面，冰溶化得很有规则，像一只倒置的茶托，在中央八分之五英寸的高度，水和气泡之间有着一个薄薄的分界线，薄得还不到一英寸的八分之一，在许多地方，这分界线中的小气泡向下爆裂，也许在最大的直径一英尺的气泡底下完全是没有冰的。

Be in from the ground in the atmosphere advection layer of 50 kilometers of 15 ～, centered the ozone gas of on the earth 90%, although its chroma never exceeds 1/100000, all concentration rises to also have a even thinner than sole only, but it assimilated opposite substance effectively harmful, wavelengh is less than the UV-C of sun ultraviolet ray of 295nm, and opposite content hurtless, wavelengh is more than the UV-A of sun ultraviolet ray of 320nm to make them all pass however, opposite content has certain harm, wavelengh is in the UV-B of sun ultraviolet ray of 295 ～ 320nm also is absorbed for the most part.

在离地面15～50公里的大气平流层中，集中了地球上90%的臭氧气体，虽然其浓度从未超过十万分之一，全部集中起来也只有比鞋底还要薄的一层，但它却有效地吸收了对生物有害的，波长小于295nm 的太阳紫外线 UV-C，而对生物无害的，波长大于320nm 的太阳紫外线 UV-A 却让它们全部通过，对生物有一定危害，波长在295～320nm 的太阳紫外线 UV-B 大部分也被吸收。

The electron microscope micrograph demonstrated that E.coli has the internal region 11 cytoplasm which and the nuclein two may distinguish, gathers round a thin cytoplasma membrane outside them and the very thick cell wall, adheres to stick cohere some end dissociation outside the cell wall the flagella.

电镜显微照片显示E.coli有两个可以区别的内部区域一一细胞质和核质，在它们外面围着一层较薄的细胞质膜和很厚的细胞壁，在细胞壁外部附着一些一端游离的鞭毛。

Although some studies have reported an incidence of calcification as high as 25 to 30 percent, others have identified it far less often. When calcification is present, however, the roentgenographic pattern most often resembles popcorn, a finding that is almost diagnostic. The presence of fat and calcium make the CT diagnosis exquisitely accurate. In a report of 47 lesions studied by CT, 30 (63.8%) contained fat only (n=18), calcium and fat (n=10) or calcium alone (n=2). Thin sections must be used to identify fat with certainty.

虽然有的研究报道钙化率可高达25 ~30 %，也有的报道远小于此，但是当钙化出现时，常表现为爆米花状，脂肪和钙化的出现在CT显示精确，在一个47个病灶的CT研究中，30个63.8%含有脂肪，10个含有钙化和脂肪，2个仅有钙化，要显示脂肪成分，必须用薄扫，由于部分容积效应，当层厚教厚时，小的空腔容易与脂肪混淆。

Serpentine rock is primarily composed of one or more magnesium silicate minerals such as chrysotile -- often occuring as fibrous veinlets in serpentine, the most common type of asbestos which separates into thin, strong, and flexible fibers that are heat resistant.

蛇纹石岩主要是由一种或更多种镁硅酸盐矿物，如温石棉-蛇纹石纤维中常见的细脉，其中的石棉形成薄的，坚韧，有弹性的耐热纤维分隔层。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
