不值

Basing on my own experimental results and that of theSLA researcher (Takayuki Nakamori 2001), I come to this tentative conclusion: UGPrinciples are accessible to all L2 learners, no matter whether the principles are instantiatedin the L1 or not; with respect to the parameters, the parametric values instantiated in the L1are initially available; while the two languages differ in parameter settings, someparameters can be resettable but to some other parameters, such as the Spec-parameter that isassociated with functional categories, become difficult even closed to the resetting; otherwiseevery L2 learner can acquire the target language successfully as well as the native speakerdoes.

根据自己的实验结果及第二语言研究者(Takayuki Nakamori 2001)的实验结果得出了这样一个结论：普遍语法中的原则对所有的第二语言习得者来说仍然可及，不管这些原则是否体现在第一语言中；但在参数方面，体现在第一语言里的参数值在第二语言习得中是可以首先习得的，但当第一语言和第二语言的参数值不同时，某些参数可以重新设定而对某些参数例如与功能管辖范围相关的具体参数就很难甚至不能重新设定；否则每一个第二语言习得者都能像母语习得者习得母语那样成功地习得目标语。

In non-contact measurement of displacement and vibration amplitude, the method of electric induced eddy-current which employs the L value measurement and frequency-modulated circuit is distinguished in the followings: the instrument based on it has a high sensitivity which is not effected by temperature variation, the initial gap can be indicated directly, unnecessity of re-calibration for different measured materials, etc.

The results show that 42.86% topsoil samples are polluted by Cadmium, soil synthesis pollution index is moderate, Cadmium pollution degree of topsoil correlate with the environment of sampling sites. The results also show that exchangeable Cd, carbonate-bound Cd, organic-bound Cd and residual Cd are found in all soil samples except for Fe-Mn oxide-bound Cd. Furthermore, the concentration of exchangeable Cd and carbonate-bound Cd, both which have high biological validity, is high. Humus has a certain correlation with exchangeable Cd, organic-bound Cd and residual Cd, and has no obvious correlation with other chemical speciations. Any chemical speciation of Cd has no obvious correlation with pH and total Fe of soil samples. Cadmium in topsoil can be eluviated by acid solution, the quantity of Cadmium eluviated by redistilled water is little. With the rise of pH of eluviating solution, eluviated Cadmium quantity decrease. For the same soil sample, the lower pH value of eluviating solution is, the more fast the Cadmium is eluviated, and the more thequantity of Cadmium is eluviated.

研究结果表明：成都市表生土壤样中有42.86%受镉污染，镉综合污染水平达中度污染，成都市表生土壤镉污染程度与采样点周围环境表现出一定的相关性；除铁锰氧化物结合态镉在部分土壤样中未检出外，所有土壤样均含有可交换态镉、碳酸盐结合态镉、有机结合态镉、残留态镉，且生物有效性较高的可交换态镉和碳酸盐结合态镉占总镉量比例较高；成都市表生土壤中的腐殖质与可交换态镉、有机结合态镉、残留态镉有一定相关性，与碳酸盐结合态镉、铁锰氧化物结合态镉相关性不显著；各形态镉与土壤pH值和全铁的相关性均不显著；土壤中的镉可被酸溶液淋出，重蒸馏水淋出镉量十分微小；随着淋滤液pH值的升高，土壤样的镉淋出量下降，且0～5小时时段的镉淋出量占镉总淋出量比例下降，5～30小时时段的镉淋出量占镉总淋出量的比例上升，对同一土壤样而言，酸度大的淋滤液比酸度小的淋滤液淋出镉速度更快，淋出镉量更大。

If the inputted accelerations are velocity-zeroized and the Damage Value is calculated according to shear stress extrema, as to 100-meter-high earth dam, Multi-Point Effect is not distinct; But as to 240-meter-high earth dam, in the part where permanent displacement and Damage Value is originally bigger the response is less tenser than that by One-Point Input, and in the part near basement the maximal shear stress and Damage Value is bigger, that is the Multi-Point Effect in time domain.

频域内多点效应与时域内有不一致的地方，即对于240米高的超大型坝，摘要对于竖向永久位移最大的坝顶部位和损伤值原本就比较高的坝顶及斜坡部位，频域内多点输入比单点输入的永久位移和损伤值反应要大些。不一致的原因在于频域内多点作用是通过拟静应力实现的。

If a class denes mutable objects and implements a cmp or eq method, it should not implement hash, since the dictionary implementation requires that a key's hash value is immutable (if the object's hash value changes, it will be in the wrong hash bucket).

如果类定义的是可变对象并且实现了 cmp或 eq方法，它就不应该实现 hash，因为字典实现一个散列表的键值是不可变的(如果对象的散列值改变了，它会放在错误的散列表位置中)。

If the content of SiH〓 kept constant, the laser energy value of threshold that decomposed SiH〓 increased linearly at first, but when the gas flux exceeded 100ml/min, the laser energy value of threshold increased slowly because the coaxial Ar could not"suppress"the reaction flame which leaded to radial dilation of reaction gases and increasing the effective absorption to laser energy.

在反应气体中SiH〓含量不变的情况下，随着反应气体流量的逐渐增加，可以引发硅烷分解的激光能量阈值一开始成线性增加，当流量大于100ml/min以后，由于同轴Ar不能有效的&压住&反应焰，导致反应气体的径向扩张，增加了对激光能量的有效吸收面积，因此激光能量阈值的增加减缓。

The paper gives stiffness matrix and mass matrix in finite element analysis of the ground vibration problem caused by track traffic by using three-dimension finite element method. Because three-dimension finite element analysis is very difficult, it is transmitted into a quadratic programming, which can be calculated by neural network.

制卡和会员卡制息品红色油不朱时，润版液的pH值给矮些；制卡和会员卡制息其他颜色的油不朱时，pH值答稍矮些。

Calculates Percentile Value statistics and the median under the assumption that your data have been grouped, and the values in the data are the midpoints of the original groups.

以下是我对这段英文的理解，不知道正确不正确，还望各位老师赐教：在你的数据已经被分组并且数据中的值是原始组的组中值的条件下，计算百分位数和中位数。

The results show that the atomic population is time-independent provided that the atoms are in |β11〉 state. For the other three Bell states, there will appear the periodical collapse revival of atomic populationif the initial mean photon number reaches some special values. With the increase of the initial mean photon number, the oscillation frequency of the time-evolution of atomic population increases correspondingly, and the amplitude decreases. The degree of the entanglement of the two-mode entangled coherent field has no

结果表明，当双原子体系的初态为|β11〉时，原子布居均不随时间变化；当双原子体系的初态为|β00〉，|β01〉或|β10〉且初始平均光子数达到一定值时，演化特性呈现周期性的崩塌-回复效应，并随初始光子数的增加，其演化曲线的振荡频率增大，振幅减小；双模纠缠相干光场的纠缠程度不影响Rabi振荡频率，但对振幅影响显著； Kerr介质与光场耦合系数达到一定值时，对Rabi振荡频率和幅度及原子布居的崩塌-回复周期产生强烈影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
