Low-Frequency Noise Properties of GaN Schottky Barriers Deposited on Intermediate Temperature Buffer Layers
Flicker noise and deep level transient spectroscopy were used to characterize defect properties of GaN films with different buffer structures. Results indicate improved properties with the use of intermediate temperature buffer layers due to the relaxation of residue strain in the films.

Geological conditions of coal and gas(oil)-bearing basins in China
There are various types of coal basins in China. Indosinian movement can be regarded as their evolutionary limit, and the basins can be divided into two developmental stages, three structural patterns and two sedimentary environments. However, only those coal measure strata that have been deeply buried in the earth are possible to be converted into coal and gas (oil)-bearing basins. Among which, only part of the coal measures possess the essential geological conditions to the formation of commercial humic oil. However, humic gas will be the major exploration target for natural gas in China. Among various coal basins, foreland basins have the best prospect for humic gas. Rift (faulted) basins accumulate the most abundance of humic gas, and are most favorable to generate humic oil. Craton basins have relatively low abundance of humic gas, but the evolution is rather great. The three kinds of coal basins mentioned above constitute China's three primary accumulation areas of humic gas: western, central and offshore areas. The major basins for humic gas field exploration include Tarim, Ordos, Sichuan, East China Sea and Yingqiong basins.

PID Controller Optimization by GA and Its Performances on the Electro-hydraulic Servo Control System
A proportional integral derivative (PID) controller is designed and attached to electro-hydraulic servo actuator system (EHSAS) to control the angular position of the rotary actuator which control the movable surface of space vehicles. The PID gain parameters areoptimized by the genetic algorithm (GA). The controller is verified on the new state-space model of servo-valves attached to the physical rotary actuator by SIMULINK program. The controller and the state-space model are verified experimentally. Simulation and experimental results verify the effectiveness of the PID controller adaptive by GA to control the angular position of the rotary actuator as compared with the classical PID controller and the compensator controller.

溶血磷脂酸受体及其信号转导
溶血磷脂酸(lysophosphatidic acid,LPA)是一种类生长因子的脂类信号分子.在血栓形成过程中被激活的血小板可以产生LPA.自从证明LPA有胞外信号功能以后,许多新的`生物活性又被不断发现.LPA最主要的作用是诱导各类细胞增殖.人们已经找到几种LPA受体cDNA克隆.LPA主要通过G蛋白偶联受体影响靶细胞功能,其信号转导系统包括已知的几条信号通路:激活Gq从而激活磷脂酶C; 激活Gi从而抑制腺苷酸环化酶并激活MAPK级联通路; 激活G12/13从而激活Rho级联通路等.

Device Length Dependency of Cross Gain Modulation and Cross Phase Modulation in Semiconductor Optical Amplifier
The cross gain modulation, the cross phase modulation and their recovery time in the SOAs with the various lengths were experimentally investigated. It was found that these values strongly depended on the device length.

Hf isotopes of the 3.8 Ga zircons in eastern Hebei Province, China: Implications for early crustal evolution of the Nort
Zircon U-Pb dating indicates that the fuchsite quartzite in eastern Hebei Province was derived from weathering and erosion of the 3.6-3.8 Ga granitic rocks. In-situ zircon Hf analyses show that the Lu-Hf isotopic system remained closed during later thermal disturbances. Zircons with concordant ages have Hf isotopic model ages of about 3.8 Ga, suggesting a recycling of this ancient crust. The ～3.8 Ga zircons have similar Hf isotopic compositions to those of chondrite, indicating that their source rocks (granitic rocks) were derived from partial melting of the juvenile crust which originated from a mantle without significant crust-mantle differentiation. Therefore, it is proposed that there was no large-scale crustal growth before ～3.8 Ga in eastern Hebei Province. Considering zircon Hf isotopic data from other areas, it is concluded that the most ancient crust in the North China Craton probably formed at about 4.0 Ga, and the possibility to find crust older than 4.0 Ga is very limited.

篇9：Identification of 3.5 Ga detrital zi
Identification of 3.5 Ga detrital zircons from Yangtze craton in south China and the implication for Archean crust evolu
The LA-ICP-MS U-Pb dating of hundreds of detrital zircon grains from the Sinian sandstones of Liantuo formation and tillites of Nantuo formation at Sanxia area in Yichang identified 3319-3508 Ma zircon grains. Their 207pb/206pb and 206pb/238U ages show excellent agreement (concordia degree 99 %-100 % ). Their CL images exhibit well-developed oscillatory zoning and the Th/U ratios are within 0. 46-0. 76, implying that they are igneous zircons which formed during middle-early Archean. These zircons are the oldest ones discovered in Yangtze craton until now. However, the detrital zircons with ages older than 3.3 Ga in the metamorphic rocks of Kongling group were not found by further investigation, which suggests the presence of crust older than high-grade metamorphic Kongling terrain in Yangtze craton.
