Analytical formulae are presented for the first time to describe the shift in the resonance wavelength of LPG in response to etching of the fiber cladding or a change in the external refractive index. The accuracy of the formula is confirmed by comparision with numerical simulations and experimental results. We demonstrated that the resonance wavelengths of an etched LPG are more sensitive refractive index than those of an unetched grating. The bending properties of long period fiber grating written in different type fiber are studied experimentally. The transmission peaks and the central wavelength of LPG change with the bending of the fiber. A new peak appears at the shorter wavelength when the fiber is being bent. The changes of the peaks are different for different photosensitive fiber. Those properties have broad application foreground in fiber sensors and tunable filters.

分别从理论和实验上对长周期光栅的折射率特性以及光纤包层半径对长周期光栅特性的影响进行了研究，首次给出了描述光纤包层半径腐蚀和外界折射率改变与长周期光栅共振波长关系的理论表达式，实验与理论和数据模拟的结果很好符合，利用腐蚀光纤包层的方法可以有效地提高LPG的折射率灵敏度；对不同光纤中写入的长周期光栅的弯曲特性进行了实验研究，LPG的透射峰形状及其中心波长随光纤弯曲而发生变化，并且随着弯曲将在短波方向出现新的透射峰，其透射峰的变化规律因所用光敏光纤的不同而不同，这一特性在光纤传感和可调谐滤波器方面有重要的应用前景。

The tidal river discharge observing system of this thesis gives a new method and experience of the hydrology observing to the river reach and cross section with complicated landform and flow, or busy shipping. This system has achieved 3 innovations: instruments for measurements which use the unmechanized rotor and continue measuring ADCP as the velocity mainframe; methods of velocity measurement which change the vertical velocity measurement to horizontal velocity measurement; the tidal discharge measurement which solve the problem that current method of discharge measurement can not achieve the accuracy of the criterion according to the continuous real time observing over the velocity of flow.

"The issue of whether access to interventional facilities affects clinical outcomes in patients admitted with acute coronary syndrome is under scrutiny," write Frans Van de Werf, from University Hospital Gasthuisberg in Leuven, Belgium, and colleagues, from the Global Registry of Acute Coronary Events Investigators."A positive association between the availability of a catheterisation laboratory and improved outcomes would argue for a change in the routing of patients with acute coronary syndrome from the nearest community hospital to a regional specialised tertiary care hospital with immediate access to a catheterisation laboratory (similar to the handling of acute trauma cases)."

In summary, the BRD7 gene acted as a candidate of tumor suppressor gene with NPC. The overexpression of BRD7 can partly reverse malignant phenotype of NPC cell line. The suppression effect of BRD7 on NPC tumorigenesis my be achieved by recognizing acetylated histone peptide through their motif-bromodomain, then modulating gene transcription by taking part in histone acetylating and chromosome remodeling, finally influencing signal-transduction pathways.

A multiplayer chip LC resonator was fabricated using planar inductor and parallel plate capacitor. Because lumped inductor has small Q value and there is stray parameter effect in high permittivity substrate, the Q value of chip LC resonator is not high. Resonators based on λ/4 stripline with end short circuited were designed and fabricated. Input and output pads, coupled to the stripline using gap-coupling capacitor, are in the same layer with the center conductive strip. This new structure is very convenient for manufacturing in comparison with the conventional structure.

采用间隙电容耦合结构实现的谐振频率为1.8GHz四分之一波长终端短路带状线单端口谐振器的Q值最大值为225，谐振频率为1GHz双端口谐振器的Q值为83，谐振频率和Q值与耦合间隙、带状线的厚度和耦合引线长度有关；二分之一波长带状线谐振器的Q值和四分之一波长相比较尺寸较大，由于导电带较长，造成金属的损耗增加，从而导致谐振器的Q值较低；带状线结构的谐振器频率调节困难，本文提出了改变接地端的宽度实现谐振频率的微调方法，可实现频率调节量约1.5%。
