The basic oils were compounded in laboratory using C5~C15 light olefin,C8~C12 light olefin and light olefin cracked from 58# wax separately. The basic oil capability in lubecant was compared and the The infection of stuff olefin to basic oil capability in lubecant was researched.
The lab high-low temperature property, oxidation stability, high temperature detergency, low-temperature sludge, wear screeningtest, L-38 bearing corrosion, MS-sequence ll D, Ⅲ D, Ⅴ: D and Cat 1G2, and standard engine platformevaluation test showed that the quality of 10W/40 SF/CD grade internal combustion oil met the specification of API SF and CD oil.
In order to make 12TBN marine diesel engine oil with medium speed and cylindrical piston type (it is called 12TBN engine oil with medium speed for short) pass the Caterpillar 1G 2 test,the simulation evaluation tests such as coke-forming plate and oxidation deposition trend at lab.
LH-02 hydrofining catalyst has been evaluated in Lab taking the reformer naphtha of Shengli Refinery as feedstock under the condition of reaction temperature 255℃, pressure 2.0 MPa, LHSV 2.0 h -1, and the hydrogen/oil volume ratio 150. The result shows that product sulfur content, bromine number, and the aromatic loss are less than 0.5 μg/g, 0.1 gBr/100g, and 1 percent point respectively.
Bromine number, sulfur content, nitrogen content and aromatic loss of the refined oil are less than 0.12 gBr/100g, 0.5 μg/g, 1 μg/g, and 1 percent point respectively. It is consistent with the Lab evaluation result.
This paper reviews the application of capillary electrophoresis in the study of explosives,depending on five modes of capillary electrophoresis and the latest research development in our lab.
The development of crystal transition technology for HNIW in the last five years is reviewed, including the modified procedures in the laboratories and the industrial process for HNIW′s crystal transitions.
The comparative test data of petroleum product test laboratories were processed by Robust Z method. The characteristics of frequency distribution of data of salfur contents in petroleum products are discussed.
The precaustic wash effect of solid base is examined in the laboratory simulation test, the results show that the life of gasoline sweetening catalyst is greatly increased after caustic wash by solid base SB-1, the caustic wash effect of solid base is same as that of caustic solution.

The evolution of activated sludge settleability and its relationship to membrane fouling in a submerged membrane bioreactor were studied at a lab-scale equipment fed with synthetic wastewater.
Engineers and scientists concerned with control problems formed new professional groupings; university courses in the subject began to be offered; and research groups were set up in industrial, academic, and government laboratories.
The text does not attempt to give a complete and meticulous account of the many relevant and excellent reports published by many other laboratories, so it is not a review of the field in a conventional sense.
Depending on the vibration frequency, the body rotation velocity in the laboratory reference system may be higher or lower than the cavity rotation velocity and in the resonance region they may differ by several times.
