Will be the world's first hot dry sludge treatment technology for the company are the United Kingdom Bradford. In 1910, the company developed the first transgenic kiln drying machine sludge and sludge applied to do the practice into the late 80's, sludge drying technology is gradually paying attention to people, sludge drying technology application and promotion, the promotion of the means of sludge treatment and disposal of the change, this change is mainly reflected in: landfill disposal of sludge prior to drying sludge treatment; the proportion of sludge disposal have been burning large improve; Do sludge Products used as a backland for sale, and other industries have been expanding.

世界上最早将热干燥技术用于污泥处理的是英国的Bradford公司。1910年，该公司首次开发了转窑式污泥干化机并将其应用于污泥干化实践，进入80年代末期，污泥干化技术逐渐为人们所重视，污泥干燥技术的应用和推广，促进了污泥处理处置手段的改变，这种改变主要体现在：污泥填埋处置前，要将污泥进行干燥处理；污泥焚烧处置比例得到了较大提高；干污泥产品作为土地回用的肥源出售，产业规模不断扩大等。

Sodium zinc chlorophyllin was prepared from the chlorophyll extracted through the processes of saponification, acidification, ironing and basification.

This paper describes the oxidation behavior of boron carbide in air bythermogravity analyses method.The lowest oxidation temperature is 420+10℃.

本文介绍了碳化硼在空气中的氧化行为，用的是热重分析法，测定出碳化硼的最低氧化温度为 420±10℃，高于 560℃氧化加速。

It was found that sodium copper chlorophyllin showed good thermal stability at the temperatures below 90 ℃ and its photo-stability was satisfactory.

以绞股蓝为原料，利用有机溶剂萃取得到叶绿素，经过皂化、酸化、铜代等过程，制备得到叶绿素铜钠盐，并测定了其对光、热及几种食品添加剂的稳定性。

It should be treated with cold-natured drugs in order to inhibit excessive yang, i.e, to cool the heat.

阴盛导致的寒证属于实寒证，应投以热性药，以化实阴，如寒者热之。

An experimental heat-transfer system as well as a data reduction procedure was established in this study on the basis of the fundamental theory of liquid crystal thermography with heating at the solid surface. The system was tested by using both the steady-state and the transient methods with single-step heating at the surface. Two problems considered in the test were the flow over a flat plat with an unheated starting length and a uniformly heated cylinder in the cross flow.

Investigations and experiments indicate that charring ablators provide the most efficient thermal protection shield for the re-entry vehicles.

载人飞船返回舱的烧蚀热防护技术研究和试验表明，碳化烧蚀材料是再入飞行器最有效的热防护层。

The enrichment of Au is closely related to the existence of pyrite-bearing hydrothermal breccias and siliceous sinter.

热田内水热爆炸和沸腾作用广为发育，Au，Ag、As、Sb、Hg、T1微量元素组异常可能是热泉型金矿化浅部的地球化学特征。

Alkylbenzene, normal alkanes and alkylcyclohexane on the pyrolysates of P. Boryanum at 300℃ had uniform distribution and the relative content of them was similar, indicating that they originated from same precursors. Fatty acids, alcohol and ketone in algal cell are the possible precursors. For example, the precursor of relatively abundant C〓 alkylbenzene and alkylbenzene with C〓 side chain perhaps related with palmitic acid. N-alkylnaphthalene in pyrolysates at 300℃ probably derived from alkylation of cleavage products of aromatic steranes and terpanes.

在盘星藻300℃热解产物中，烷基苯、正烷烃和烷基环己烷碳数分布一致、各化合物的相对含量接近，表明它们有相同的来源，藻类体内的脂肪酸、醇和酮及细胞壁等物质可能是其母质，相对含量较高的碳数为16及侧链碳数为16的烷基苯类化合物，其前身物可能与软脂酸有关。300℃热解产物中的正烷基萘类化合物，可能由芳香甾、萜类的降解产物与直链烃类加成烷基化而形成。

It is clarified for the first time that the thermal fatigue failure of solder joint is actually a creep strain low cycle fatigue failure, and a physical model for creep fatigue crack propagation has been proposed. It was pointed out that creep strain increases in the high stress area ahead of the tip of thermal fatigue crack, results on one hand that the slide of crack tip increase, inactivation more serious and crack close length increases, the other hand, that intergranular crack exists, whose direction will affect the fatigue crack propagating.

本文首次阐明了焊点的热循环失效本质上是以焊点内循环蠕变为主要应变的低周疲劳失效，并在此基础上提出了蠕变疲劳裂纹扩展的物理模型，指出热循环裂纹前端的高应力区内，蠕变加剧，使裂纹前端滑移增加，裂纹钝化加剧，导致随后的裂纹闭合扩展长度增加；同时蠕变也使裂纹前端的高应力区出现晶间裂纹，蠕变沿晶裂纹对主裂纹扩展的影响取决于沿晶裂纹的连接方向。
