《我的世界》物品ID有哪些?
Index tests are the most basic types of laboratory tests performed on soil samples. Index tests include the following:1) Water content ( also known as moisture content) .
2) Wet density determinations ( also known as total density) .
3) Specific gravity tests.
4) Particle size distributions and Atterberg limits ( used to classify the soil) .
5) Laboratory tests specifically labeled as index tests,such as the expansion index test, which is used to evaluate the potential expansiveness of a soil.
Water Content Test. The water content test is probably the most common and simplest type of laboratory test. This test can be performed on disturbed or undisturbed soil specimens. The water content test consists of determining the mass of the wet soil specimen and then drying the soil in an oven overnight ( 12 to 16 hours) at a temperature of 110℃ ( ASTM D2216 - 92,1998) . The water content wof a soil is defined as the mass of water in the soil divided by the dry mass of the soil,expressed as a percentage. Water content values are often reported to the nearest 0. 1 or 1 percent of measured value. Table 5. 2 provides guidelines on the amount of soil that should be used for a water content test based on the largest particle dimension.
Table 5. 2 Minimum soil sample mass for water content determination
Values of water content wcan vary from essentially 0 up to 1200 percent. A water content of 0 percent indicates a dry soil. An example of a dry soil would be near-surface rubble, gravel,or clean sand located in a hot and dry climate,such as Death Valley,California. Soil having the highest water content is organic soil,such as fibrous peat,which has been reported to have water content as high as 1200 percent.
Total density and total unit weight. The total density ( also known as the wet density ) should be obtained only from undisturbed soil specimens,such as those extruded from Shelby tubes or on undisturbed block samples obtained from test pits and trenches. when extruding the soil from sampler tubes,it is important to push the soil out the back of the sampler.
The total unit weight is defined as the wet soil weight per unit volume. In this and all subsequent unit weight definitions,the use of the term weight means force. In the International System of Units ( SI) ,unit weight has units of kN / m3( kilonewton per cubic meter) ,while in the United States Customary System ( USCS) ,the unit weight has units of pcf,but this implies pounds of force ( lbf) per cubic foot.
Specific gravity. Specific gravity is a dimensionless parameter that relates the density of the soil particles to the density of water. For soil,the specific gravity is obtained by measuring the dry mass of the soil and then using a pycnometer to obtain the volume of the soil. Because quartz is the most abundant type of soil mineral,the specific gravity for inorganic soil is often assumed to be 2. 65. For clays,the specific gravity is often assumed to be 2. 70 because common clay particles,such as montmorillonite and illite,have slightly higher specific gravity values.
Oversize particles are often defined as gravel and cobbles that are retained on the 3 /4 in( three fourths inches) sieve. For these large particles,there may be internal rock fractures, voids,or moisture trapped within the gravel and cobbles. The specific gravity test procedures and calculations can include these features and the test result is referred to as the bulk specific gravity.

扩展资料:
如果上方ID显示不全,玩家也可以在游戏中自行查找ID。
首先在游戏中按下F3+H,游戏画面的左下角就会出现相应的提示“高级提示框 显示”;
然后打开物品栏,把屏幕中的准星对准想要查看的物品,ID就会在屏幕中显示出来了。
《我的世界》物品ID即代表了某个物品,主要在一些诸如“/give xx ID 数量”等涉及物品的指令中使用。
比如,在游戏内,输入“/give(空格)ABC(玩家名) 1(空格)1(空格)0”指令分解
意思就是这个指令给了叫做ABC的玩家一个石头。

在陶瓷学中,将SiO2的天然矿物原料称为石英原料。其主要类型有:脉石英、石英砂、石英砂岩、石英岩(硅石)、石英质砾石及硅藻土等。制造硅质耐火材料用的硅石只有石英原料的一个类型。
1.脉石英
脉石英(Vein quartz)颜色洁白、致密块状的石英,半透明,贝壳状断口,油脂光泽,因呈脉状产出,故称脉石英,属于结晶硅石的一种。它是岩浆期后从岩浆中分异出来的二氧化硅热溶液,充填在早期形成的岩石裂隙中冷凝而成,SiO2的含量可达97%~99%之间。它是生产日用陶瓷的优质原料,但由于它呈致密块状,加热时体积膨胀剧烈,通常需要预先煅烧、加工碾碎后使用。脉石英也是制造高硅质,高密度硅砖的原料。我国广西、山东、江苏北部等地出产脉石英。
2.石英砂
石英砂(Silica sand)又称硅砂,是由粒径0.1~2mm的石英组成的砂粒,通常由暴露在地表的石英质母岩,如花岗岩、伟晶岩,片麻岩经风化、破碎而形成。它在第四纪沉积物以及现代河流、湖泊、海滩中广泛分布。天然石英砂有海岸砂及山砂。石英砂中常含杂质,一般应予选矿处理。其品位根据其中的Fe2O3、Al2O3、CrO3、TiO2的含量及其粒度组成而定。由硅石和石英砂岩粉碎加工亦可制得石英砂、它们均是玻璃工业的主要原料。
3.石英砂岩
石英砂岩(Silicarenite)是一种固结的砂质岩石,由砂质硅结物硅结石英砂粒而成。砂粒中石英的含量在99%以上;硅质胶结物为蛋白石及玉髓,他们可以围绕石英砂粒发育成次生加大胶结物,形成沉积石英岩。根据颗粒大小分为粗粒砂岩、中粒砂岩与细粒砂岩;按胶结物的不同分为:钙质砂岩、硅质砂岩、长石质砂岩等。石英砂岩随胶结物的不同而呈白、黄、红色等。有时因为风化影响而使结构松弛,成为软砂岩。质地纯净者,SiO2含量可达97%以上。在陶瓷工业中,石英砂岩主要用做瘠化料,以降低坯体的可塑性,减少制品的干燥收缩与变形;含硅高、含铁低的砂岩,一般可用语玻璃工业;水泥工业中多用做硅质校正原料,用于调整熟料的硅酸率。我国华北震旦系地层,华南泥盆系地层中石英砂岩和沉积石英岩分布很广。
4.石英岩
石英岩(Quartzite)亦称硅石,是由石英砂岩受动力变质作用而生成的变质岩,主要由石英的颗粒集合体所构成。由于在变质过程中石英颗粒发生重结晶、挤呀等现象,因而岩石的硬度和强度都较石英砂岩大,端面致密,在显微镜下,石英颗粒之间呈锯齿状接触。根据变质程度,分为砂岩质石英岩,再结晶石英岩(结晶硅石)和胶结石英岩(胶结硅石)。石英岩广泛用作玻璃、水泥、陶瓷工业中的原料。在耐火材料工业中常用于制造高硅质、高密度硅砖。我国辽宁石门、河南铁门、山东王村、湖南湘乡等地出产结晶硅石;山西五台则出产硅结硅石。
5.石英质砂石
石英岩砂石(Quartz gravel)外形如鹅蛋,故俗称“鹅卵石”,通常呈白色、灰色,亦有黑色者。色白者由石英岩、石英砂岩或脉石英经风化、破碎、磨圆而形成。色黑者多有燧石组成(燧石是一种硅质化学沉积岩,常呈层状、结核状产于石灰岩中)。质地坚硬,硬度为7。陶瓷与耐火材料工业中常用于球磨机的磨球。质地纯净的亦可作为陶瓷坯、釉的原料。鹅卵石产于多山的海滨及山区河滩中,如大连、青岛海滩;在第四纪沉积层中也有广泛分布,如南京附近的雨花台砂石层。
6.硅藻土
硅藻土(Diatomaceous earth)是由海水或淡水中的微生物——硅藻类的遗体骨骼(硅壳)堆积而成,本质上是含水的非晶质而氧化硅。硅藻土中硅藻的含量可打达70%~190%,SiO2含量一般在70%以上,呈多空状结构,故亦有人称之为细胞状硅石。比重2.1~2.2,硬度小,常含有粘土、火山灰、有机物等杂质而呈白、黄、粉红,甚至褐、黑等色,以白色者为优。其特点是吸附能力强,是良好的吸附剂以过滤材料,亦为绝热、隔音的优良材料,用于制造多孔陶瓷于轻质隔热砖。硅藻土多产于第三纪和第四纪的湖相、海相沉积地层中。
