In order to overcome the difficulty in estimating the ripple component on dc-side capacitor reference voltage, the modified control algorithm is proposed by ignoring the ripple component. Furthermore, the relation between control performance and damping coefficient is researched. In addition, the reasons of voltage source converter inner-loop control overmodulation are also analyzed. Based on the relation between control performance and VSC inner-loop input saturation, damping coefficient is adjusted on-line by fuzzy logic reasoning so that the trade-off between control accuracy and limitation of VSC inner-loop control overmodulation is solved preferably.

由于在线计算直流电容指令电压波动量十分困难，在控制方法的执行中忽略波动量的影响，简化了控制方法的实现；此外，该方法还研究了所注入的阻尼大小对控制效果的影响以及APF内层控制过调制产生的原因，针对无源性控制律跟踪精度的要求与内层控制过调制限幅条件间的矛盾，通过构造模糊逻辑推理环节实现阻尼系数的在线调整，在满足内层控制限幅条件下确保跟踪精度和补偿效果。

但并非所有激活源事件的被试都能成功解决九点四划问题，这取决于从源事件中所提取的启发信息的质量。研究结果还表明，内隐学习组与外显学习组正确解决九点问题的人数百分比差异并不显著，证明源事件中所包含的启发信息的激活，可能主要是自动加工的结果。

In combination with seismic reflection features and probable gas resource discussion, it is concluded that there probably exist two kinds of reservoir models in the X Block. In the areas where faults or collapse structures develop, the gas resource is probably composed of thermogenic gas, gas hydrate is characterized by multilayer distribution, while in the inactive areas the gas resource is probably composed of biogenic gas, and gas hydrate is characterized by monolayer, which mainly distributes in a narrow zone on the surface of BSR (bottom-simulating seismic reflector).

结合地震反射特征和可能的气源讨论初步认为，X区块天然气水合物的成藏模式主要有两种类型：在断裂或滑塌构造发育区，水合物的气源以热解成因气为主，水合物呈多层分布；在构造平缓地区，水合物的气源以生物成因气为主，水合物呈单层分布，且主要分布在似海底反射之上一个狭窄的范围内。

Recently, it is found that the neuron apoptosis caused by brain ischemia is associated with signal pathway of endoplasmic reticulum stress, which is different from the traditional apoptotic pathway. Caspase-12 has been identified as a molecule which initiates apoptosis selectively in response to ER stress and is not activated by other pathways. Caspase-12 is localized on the ER membrane, but once specifically activated by ER stress, it translocates to the cytoplasm.

最近的研究发现，这种细胞凋亡与内质网应激(endoplasmic reticulum stress ER stress)有关，其是一种不同于经典的凋亡途径的新途径，分子伴侣葡萄糖调节蛋白78(glucose regulated protein， GRP78/Bip)表达增高是反应ER stress的最敏感的指标，胱冬酶-12(caspase-12)为鼠源性的内质网膜上的蛋白，它的特点是只被内质网诱导的凋亡所激活而不被其它非内质网因素所激活。

从时间分辨的X光强度轴向空间分布来看，在较长时间（约1～1.5ns）内，O带X光在整个观测缝对应的轴向范围之内均有较大的辐射强度，在X光强度空间分布的变化过程中，其强度峰值的空间位置基本不变；而对N带X光，则只在较短时间（约0.5ns）内，在整个观测缝对应的轴向范围之内可观测到X光辐射，但只在靠近输运源约300μm的范围内有较强发射，在柱腔末端600～700μm范围之内的辐射则很弱，N带X光辐射轴向空间分布曲线的峰值位置在朝柱腔末端的方向移动，移动量大约为130～250μm。
