本文讨论了用氧化二异丙苯硫化的天然橡胶在苯中溶胀后冰点下降（△T）的测定方法。Kuhn曾提出与冰点下降△T成反比的参数αH,本文采用参数αH作为衡量冰点下降的指标。同时,讨论了异常冰点下降的原因,认为这是由于网状链的周围形成苯的“非冻区”所致。本文比较了理论上的衡量标准与实验结果。所得结果清楚地表明,αH值不仅在数量上与用普通的方法测得的网状链密度相一致,同时还能反映出已降解和未降解的硫化橡胶三维网状结构之间的差异。

在JT－60U上已全面研究了基于负主了子的中性束注入（NBI）电流驱动和加热性能。根据注入的中性束（350keV)的射穿测量已证实，高能粒子的电离过程中多级电离过程是主要的。实验已测出基于负离子的NB（N－NB）驱动的电流密度分布。与理论预言良好一致，且在EB＝360keV、PINJ＝3．7MW时，N－NB驱动的电流达0．6MA。电流驱动效率ηCD通过升高电子温度而提高，通过增加束能而改善。来自N－NB的快离子在由于反剪切等离子体的极向磁场而引起的约束增强的芯部被完全约束。在以N－NB为主的加热下实现了H模式的明显转变，其中H模式转变所需要的净吸收功率类似于以前在JT－60U上用低能束（90keV）获得的结果。在N－NBI强电子加热（80％被电子吸收）下，在稳态ELMy阶段获得，当Tc(0)＝1．4Ti（0）时H因子（＝τE／τE^ITER－89PL）为1．64。

JT-60U中基于负离子的中性束注入（N-NBI）电流驱动的能力已扩展到反应堆相关的工况。在离电子温度工况Te(O)≈10keV下已估计了驱动电流分布和电流驱动效率，并已证明在这种工况下它们与理论预测是相当一致的。在360keV束能下注入3.75MW功率，N-NB驱动电流达到1MA。在Te(O)≈13keV下，在高βpH模等离子体中获得的电流驱动效率为1.55×10^19A·m^-2·W^-1，该值接近ITER要求。这种电流驱动性能在等离子体电流为1.5MA的全电流驱动条件下能够维持高β(βN=2.5)和高约束（Hhy2=1.4）等离子体。研究了不稳定性对N-NBI电流驱动的影响。当用N-NBI驱动的类脉冲不稳定性发生在中心区域时，观察到由于束离子的损失而导致磁轴附近环电压及中子产率降低，尽管损失的驱动电流顶多只有总驱动电流的7％。当新经典撕裂不稳定性出现在高β等离子体中时，离子束的损失随不稳定活性的增大而增强。

To measure integral doses in image-guided radiation therapy, we developed a disposable mini-substrate with a 1.0-μF condenser and a silicon X-ray diode (Si-XD). The Si-XD is a high-sensitivity photodiode selected for detecting X-rays. In the substrate with dimensions of 15 × 15 mm2, the initial charging voltage is 3.30 V, and the charging voltage is decreased by photocurrents flowing through the Si-XD during X-ray exposing. The condenser in the substrate is charged by a microcomputer dock, and the charging voltage is also measured using an analog to digital converter in the dock after exposing X-rays. The dock is connected to a personal computer through a USB cable, and integral doses are shown on the PC monitor. The doses were proportional to decreases in the charging voltage, and the calibrated doses corresponded well to those obtained using a readily available ionization chamber.
