形成边缘

In the hot sun of summer, the water of Spotted Lake , located in British Columbia and Washington, evaporates and crystallizes the minerals, forming many white-rimmed circles: shallow pools that reflect the mineral content of the water in shades of blues and greens.

斑点湖位于英国的哥伦比亚和华盛顿之间，其湖水会在炎炎夏日下得以蒸发，露出湖底的矿物质，由此而形成诸多白色边缘的圆圈：这些圆圈其实是一个个浅浅的小水湖，富含矿物质湖水呈现出绿色和蓝色。

Over time, both the wind and radiation blast away surrounding cloud material, carving out expanding cavities.

Taking Bendong and Xiqiu granitic bodies as an example, the thesis expounds geochemical characteristics of mantle-derived type granitoids in Sourthern China in REE and trace elements as follows: lower ∑REE, obvious fractionation of LREE and HREE, negative anomaly of Eu, relative higher ∑LREE/∑HREE,〓 and 〓 ratioes, rich in transitional elements and poor in large-ion lithophile and immobile elements compared with acidite means by Vinogradov. Original mantle-normalized distribution pattern of incompatible elements is one kind of rich -in-strongly incompatible elements type with enrich of K and loss of Sr, P, Ti and trace element association makes a feature of siderophile and chalcophile elements. The tectonomagmatic discriminating shows that mantle -derived granitoids in Southern China belong to orogenic granitoids formed in island arc/marginal sea basin system.

以本洞和西裘岩体为例，论文阐明了华南幔源型花岗岩稀土和微量元素地球化学特征，表现为稀土总量较低，轻重稀土元素分馏明显，负铕异常和∑LREE/∑HREE、〓、〓比值较高，与维氏酸性岩平均值相比华南幔源型花岗岩过渡族元素含量较高而大离子亲石元素和非活动性元素含量较低，不相容元素原始地幔标准化分配型式属强不相容元素富集型并呈K富集而Sr、P、Ti亏损的特点，微量元素组合以亲铁和亲铜元素为特征，构造岩浆判别显示华南幔源型花岗岩属造山花岗岩，其形成构造环境为岛弧/边缘海盆系统。

At the same time, the salt in the layer of soil has experienced from low to high then to low. In the alluviation fan and the top of alluvial plain, the soil salt form gathering is strong, that is to say, the content of salt relatively high in the layer of soil, but reduced in the bottom of soil. At the bottom of valley, the salt content increase from upper and bottom of soil, especially at the desert edge, this kind of trend is more obvious. Differentiation of soil characteristic was exited in mountain-basin system, and agriculture development should follow this rule.

土壤盐分空间变化规律明显：在前山区地带，土壤含盐量低；在冲积扇、冲积扇缘及冲积平原上部绿洲区，土壤耕层总盐高、表聚性强；从冲积平原中下部到亁三角洲绿洲，耕层盐分含量依次降低，但剖面盐分含量呈现依次增加趋势，形成盐分聚集的漏斗效应，尤其进入沙漠边缘区，这种趋势更加明显。

A vast alluvial fan blossoms across the desolate landscape between the Kunlun and Altun mountain ranges that form the southern border of the Taklimakan Desert in China's XinJiang Province.

广阔冲积扇开花整个荒凉景观之间的昆仑和阿尔金山脉，形成南部塔克拉玛干沙漠边缘，在中国的新疆建省。

It is the first time that these phenomena were observed: Two nuclei are surrounded by plasma and locate at the central of the female gametophyte and the others nuclei are positioned at the fringe of the female gametophyte; Before the pollen tube enters the female gametophyte. the nuclei in chalazal end begin splitting of plasma and form multinuclear cell.4. The pollens of Gnetumc are spherical or applanate with single aperture. The ornamentation of exine is spine. The basis part of spine is lenience and the top part of spine is tip or obtuse sphere.

首次在买麻藤属植物的雌配子体中观察到2个游离核位于配子体的中央位置，且被一团原生质所包围的，其余的游离核位于边缘的现象以及花粉管进入雌配子体前，合点端的核已经发生胞质分裂形成多核细胞的现象 4、买麻藤的花粉近球形或扁平型，有单萌发孔，外壁表面具小刺状纹饰，小刺基部宽大，末端尖或钝圆。

Balas breed fructification, go up to form Brown circle spot for the center with leather aperture in fruit face more, brim clarity, cave a bit, but not thorough pulp, only cuticular below a few cells become angry.

Colonies on improved agar, when grown 24～48 hours at 37℃ in a candle jar, are 1～2mm in diameter, convex, entire, transparent, glistening, and butyrous. Some strains produce slimy growth. Colonies on clear media are iridescent when observed with obliquely transmitted light.
