有重量的

Its lumber material is narrow for the alburnum, distributes in north compared to the south narrowly, light yellow arrives the yellow light yellow, the heartwood to brown brings slightly red; Has the resin, the durability is bad; The lumber texture, the density, standard natures and so on the festival receive the geography condition influence which grows, is widespread as a result of this lumber distribution, but therefore the lumber material the variation is greatly more obvious than because of the condition other tree seeds; The lumber weight is ordinary, solid.

其木材材性为边材窄，分布在北部的比南部的更窄，浅黄到黄色，心材浅黄至褐色略带红色；有树脂，耐久性差；木材的纹理、密度、节子等格质均受生长的地理条件影响，由于该木材分布广泛，所以木材的材性因条件而变异大比其他树种明显；木材重量一般，较结实。

He mentally visualizes a complex form from all round itself; he knows while he looks at one side what the other side is like, he identifies himself with its centre of gravity, its mass, its weight; he realizes its volume, as the space that the shape displaces in the air.

他的大脑能从物体周围的各个角度勾画出其复杂的形象，他看物体的一边时，便知道另一边是个什么样子。他把自身和物体重心，质量，重量融为一体。他能意识到物体的体积，那就是它的形状有空气中所占的空间。

The virgin thermoplastic polyurethane and the thermoplastic polyurethane of the scrap material are polymerized using at least about 60 percent by weight, based on the weight of the polyurethane produced, of a polyester diol having a weight average molecular weight of at least about 500 and having from four to five carbon atoms between substantially all of the ester groups.

未使用过的热塑性聚氨酯和废料的热塑性聚氨酯是使用至少约60wt％的聚酯二醇聚合而成的，基于产生的聚氨酯重量。其中该聚酯二醇的重均分子量为至少约500，并基本所有的酯基团之间均有4～5个碳原子。

The main structure of airplane tire is divided in to have no inner tire tire and has an inner tire tire, they become the help buffer airplane of an air mat layer lands process in of vibrate and runway of rough gravamen;On the ground, when they prop up aero weight, and land, they provide an essential brake to combine dint for making to move and making the airplane come to a stop.

一些关于飞机的中文翻译成英文，请求帮助飞机轮胎的主要构造分为无内胎轮胎和有内胎轮胎，它们形成一个空气垫层帮助缓冲飞机着陆过程中的震动和跑道的粗糙不平；在地面上，它们支撑着飞机的重量，并且着陆时，它们为制动和使飞机停下来而提供必需的刹车结合力。

From thermal analysis, weight loss occurs pronouncedly at temperatures above 300 oC in air and the residual weight increases with the reaction temperature. The particle size decreases with the increasing ethanol concentration., while the BET surface area decreases when the concentration of water is increased. Pore size measured from the as-synthesized particles is about 2.7 - 4 nm and this becomes slightly smaller after calcination which is about 3 - 5 nm.

TG/DTA中温度上升至约300 oC时，重量开始明显失重，随著合成反应温度上升，最终残留量由1~3%提高为约5~7%，动态光散射粒径分析发现随著乙醇含量增加，煅烧前与煅烧后的粒径尺寸均有下降趋势，随著水含量的增加，比表面积值随著下降，煅烧后的壳层孔隙尺寸约为3~5nm，煅烧前的壳层孔隙尺寸为2.7~4 nm，煅烧后的孔隙度会略为上升。

At the same time, the roof truss and cable-state composite hanging basket in the paper is also an idea structure in bridge construction.

同时，提出并设计的新型斜拉式组合挂篮是一种较为理想的重载轻型挂篮形式，在块件重量重的大跨度桥梁的施工中有较大的优越性。

Linen also comes in varied quality and weight, has a finer and smoother texture than cotton, and unprimed linen is light brown in color. I prefer the surface of linen for painting, however, it is more expensive. If you plan to do more than a few paintings, it is usually better to buy a larger piece of canvas, since less will be wasted with a larger piece when cutting for various canvas sizes. You can find fabric canvas, and panels and pre-stretched canvases in art stores, and some office supply stores and department stores carry canvas panels and pre-stretched canvases.

床单也丰富多彩的质量和重量，有一个更精细和平滑纹理比棉， unprimed亚麻是浅棕色的颜色，我喜欢表面上的麻布画，却是更昂贵的，如果您打算做多过几个画，它通常不如买一个大尺寸的油画，自少被浪费了一个更大的片切割时，由于种种画布大小，你可以找到面料帆布，和小组预拉伸画布在美术商店，及一些办公用品商店及百货公司进行帆布板和预拉伸画布。

His Aptera, which he designed in his garage in Carlsbad, California, is a three-wheeled, bullet-shaped two-seater that minimizes drag and weighs only 850 pounds (the Toyota Prius weighs 2,890 pounds).

他的 Aptera ，这个他在加州 Carlsbad 自己家车库里设计的交通工具，这是一个三轮的，水滴形的，双座的载具，它最小化了牵引力和重量，仅有850磅（丰田 Prius 重2890磅）。

Instead, the erosion resistance is increased after FSP. The refined and uniformly distributed second phases, which are resulted from the FSP, can help to increase the hardness and further reduce the brittle fracture of the specimens. Si and nvAl3CuNi phases are usually found near or end of the grooves with little fracture. But the τ1 (Al9FeNi) phase is easier to be removed by the erodent cutting. It can be inferred that Si and nvAl3CuNi are useful to improve the erosion resistance of A384 aluminum alloy, but τ1 (Al9FeNi) phase is detrimental for the erosion resistance of A384 aluminum alloy.

经摩擦搅拌制程改质后，硬度提升，晶出相细化且均匀分布，降低脆性龟裂的现象发生，有助於改善A384铝合金的磨耗性质，其中，亦发现在冲蚀沟槽附近有残留和脆性破裂之共晶Si颗粒和nvAl3CuNiw晶出相，推测此两相为A384铝合金中有助提升磨耗阻抗的第二相；而τ1(Al9FeNi)晶出相则容易受到冲蚀颗粒的切削而被冲蚀颗粒移除，增加材料的重量损失，推测τ1(Al9FeNi)晶出相为A384铝合金中较不耐磨耗的晶出相。

Upstream has formed an annual output of 300,000 tons has a high-quality silicon mines, when the glass holding company Silicon Mine Ichang limited liability company is a large production base of raw materials of silica, there are two domestic beneficiation of silica sand advanced production lines, annual output of fine quartz sand 300000 t / a, is South Africa's largest silica sand base; mid-stream has a 450t / d, 500t / d float glass production lines and 600 / t self-cleaning glass substrate production line of the article, an annual output of float glass production capacity of 10 million weight boxes; downstream has a glass cover, TiO2 thin-film self-cleaning glass, tempered glass, insulating glass, such as a number of glass deep-processing production lines, processing 3 million square meters of glass products.
