It is first reported and studied systematically about the changes occured during calcination, reduction and re-oxidation treatments of Pt ammine complex supported on β zeolite.

一。首次系统地研究了β沸石上Pt胺化合物经分解、还原及再氧化等处理过程中发生的变化，并提出关于Pt粒子大小及其状态变化的模型。

The chicken will cook more rapidly in the boiling water if holes are pricked in it with a fork first.

可先用叉子在鸡胸肉上戳几下，再放入沸水中煮，容易煮熟。

In addition, the low-temperature heat utilization in deaeration of desahed water and temperature elevation of deaerated water is explored on the basis of refinery system integration and optimization.

其次从炼油厂系统整合优化角度探讨除盐水在除氧环节以及除氧水在升温环节低温热利用的途径，通过技术改进和系统低温热利用相结合，探讨芳烃精馏塔实现回收低温热和消除装置瓶颈的可行性，提出利用区域除盐水集中升温除氧以及区域除氧水先集中升温再进汽包产汽的芳烃脱庚烷塔低温热利用方案，不仅能回收67％的低温热，产生的1.4MPa低压蒸汽（10t／h）还可代替连续重整装置脱已烷塔重沸器的中压蒸汽。

Heat oil, fry minced garlic, add ground pork, stir fry until pork turns white. Add preserved soy paste and mushroom, then add tofu, soy sauce, salt, and add water to submerge the content. Boil for about 10 minutes. Mix corn starch with water, pour the mixture in pot, sprinkle pepper, and green garlic.

炒锅放入植物油烧至5成热，放蒜末煸炒至金黄色，放肉末炒至肉末变色，放豆瓣酱、香菇略炒，再放豆腐、生抽、盐、高汤，烧沸片刻；放味精，用水淀粉勾芡，撒上胡椒粉、青蒜段，出锅装盘。

We suggested that the surface and framework around secondary pores were dissolved by KOH solution, then reinsertion of aluminum into the framework vacancies of EDY occurs.

在没有外加铝源的情况下， KOH溶液也可以铝化EDY样品， KOH溶液首先溶解EDY表面相及二次孔周围的沸石骨架，然后这些溶解下来的铝碎片再填充到EDY的骨架空位中去，致使其Si/Al比降低。

Autoreduction of Pt〓 ionsin β zeolite is found directly by means of CO-IR and TPR methods.

一。首次系统地研究了β沸石上Pt胺化合物经分解、还原及再氧化等处理过程中发生的变化，并提出关于Pt粒子大小及其状态变化的模型。

Some primary beryl crystals are found in spodumene in zones Ⅲ and Ⅳ, and are enriched in Fe and Mg. The late secondary beryls with low contents of Cs2O are attributed to crystallization of pullucite and nanpingite. There is possibly a re-equilibrium between the late hydrothermal fluids and the Cs-rich beryl.

晚期绿柱石的Cs2O含量较低，可能是由于艳沸石和南平石等铯矿物的结晶，导致晚期熔体－热液中相对贫铯，而热液流体与富铯绿柱石之间可能存在艳的化学再平衡。

Compared the voltage negative feedback wire-feeding speed regulation system supported by current positive feedback with the rotational speed negative feedback regulation system, the equivalent condition of the two systems is obtained. Then, a wire-feeding speed regulation circuit for the CO_2 welding machine is designed based on TL494 chip, which has the self-protective function under the condition of current overloading.

通过对电压负反馈配合电流正反馈的送丝调速系统与转速负反馈调速系统的比较，得出了这两种调速系统的等效条件，并采用电压负反馈配合电流正反馈技术，设计了一种以TL494为核心的具有过电流截止保护功能的CO_2焊机送丝调速电路。
