Thesolution of collagen-PVA was wet spined with the sodium sulfate as coagulant and collagen-PVA composite fibers were prepared. 在此基础上,以硫酸钠为凝固剂,对胶原-PVA共混溶液进行湿法纺丝,制备了胶原-PVA复合纤维。
A structure method of the commutative semigroup by using the structure functions is offersed, and givesn the characterization of homomorphism and isomorphism of commutative semigroups and the spined product of commutative semigroups. 用结构函数给出一种方法,用以刻划任意交换半群的结构,并用来刻划交换半群同态与同构及交换半群的织积。
In the experiment, reported in tomorrow's issue of the journal Behavioral Ecology, scientists caught 270 nine-spined sticklebacks from the Melton Brook in Leicestershire. 在明天出版的《行为生态学》杂志上发表的这一研究实验中,科学家们在莱斯特的梅尔顿布鲁克小溪捕获了270条九刺鱼。
The three-spined species, shown here in the waters off Western Australia, is among the largest of the toadfish, reaching 12 inches ( 30 centimeters) long. 这3脊刺物种,显示这里在水域离开西澳大利亚,是其中最大的蟾鱼,延伸12英寸(30厘米)长。
While purple-toed, keen-eyed hunters are just a made up example, a real animal that demonstrates this is the three-spined stickleback fish of western Canada. 紫色的脚趾,敏锐的视力都只是编出来的例子,加拿大西部的三刺鱼为我们展示进化历程,这是一种真正存在的动物。
The spines of the omnivorous pencil-spined urchin ( Eucidaris thouarsii) extend outward from its body. There are some 700 species of sea urchins worldwide. 在自然界模式。这个脊骨的杂食的铅笔-有刺的海胆从它的身体延伸向外。全世界约有700种类的海胆。
Whoever excavates and robs fossils of ancient human being or ancient spined animals of scientific value shall be punished according to the provisions of the preceding paragraph. 盗掘国家保护的具有科学价值的古人类化石和古脊椎动物化石的,依照前款的规定处罚。
In particular, we establish the weak spined product structure of the class of semigroups. 特别地,建立了一个wrpp半群满足置换恒等式的弱织积结构。
After giving some characterizations of left C a semigroups, the concept of pseudo spined product is to be defined and the new structure of left C a semigroup is to be given. 在给出左C-a半群的一些特性之后,定义了伪织积的概念,并给出了左C-a半群的一种新结构。
