    • A splendid tentative surface protective coating which is useful in treating a surface of a substance by soldering or plating and which is peeled off easily from the surface after the treating is formed by preparing a solventless or solvent free type screen ink based on essentially an ultraviolet ray-curable rubbery elastomer, applying a coating of the ink on the surface of the substrate by screen printing or thin film coating, and curing the coating of the ink by irradiation with an ultraviolet ray. The tentative surface protective coating can reproduce exactly a pattern of a mask or screen, have a high chemical resistance and heat resistance, even if it has a thin thickness of 30 .mu.m, and have no afraid of deformation caused by heat curing, whereby a precise and shortened surface treatment of the surface of the substance can be afforded. Also, working environment is improved, and air conditioning equipment can be dispensed with owing to an absence or diminishment of an organic solvent. In addition, according to the present invention, an excellent ink composition is provided which is much suited to screen printing.

    • A mass spectrometry apparatus is provided with an emitter for emitting metal ions, a reaction chamber where the detected gas is introduced and ionized by the metal ions, an aperture for guiding molecules of the ionized detected gas, and a mass spectrometer for measuring the guided molecules. The metal ions emitted from the emitter are caused to fly to the reaction chamber to ionize said detected gas. The detected gas is a halide compound. Further provision is made of a sample gas source for feeding a halide compound to the reaction chamber and an N2 gas source for feeding to the reaction chamber a gas (N2 etc.) to which the metal ions attach less easily than to the halide compound. It is therefore made possible to apply cation attachment of the Fujii system to mass spectrometry of a halide compound and enable precise measurement of fluoride compounds etc. having a large impact on global warming.

    • A method for determining the core flow rate from pump differential pressure method equations and a heat balance equation for determining the temperature and density of the reactor water in the downcomer and lower plenum region. The measured reactor water temperature is used only as an initial estimate for this new method. This allows the first estimate of the core flow to be determined based upon the reactor water density that corresponds to this temperature and the pump differential pressure and pump rotational speed measurements. Then, with this intial core flow measurement value, and other available plant measurements and assumed nominal values for the heat balance equation, revised values for the reactor water temperature and density can be calculated. Using a standard numerical method, such as the successive approximation technique, a more accurate estimate for the reactor water density can be obtained. A more accurate value for the core flow can be determined by the pump differential pressure method core flow equation using this more accurate density estimate. The iterative process is continued until tightly converged values for the calculated core flow and calculated reactor water temperature and density are obtained. By this approach, the overall accuracy of the calculated reactor core flow and the reactor water temperature/density is improved.
    • 一种用于通过泵差压方法确定核心流量的方法和用于确定降液管和下部气室区域中反应堆水的温度和密度的热平衡方程。 测量的反应器水温仅用作这种新方法的初始估计。 这允许基于对应于该温度的反应堆水密度和泵差压和泵转速测量来确定核心流量的第一估计。 然后,利用该初始核心流量测量值和其他可用的工厂测量值和假定的热平衡方程的标称值,可以计算出反应器水温和密度的修正值。 使用诸如逐次逼近技术的标准数值方法可以获得反应堆水密度的更准确的估计。 通过使用这种更准确的密度估计的泵差压法核心流量方程可以确定核心流量的更准确的值。 继续迭代过程,直到获得计算的核心流量和计算的反应器水温和密度的紧密收敛值。 通过这种方法,提高了计算出的反应堆堆芯流量和反应器水温/密度的总体精度。
