不偏性

The maximum principle of the optimal control for the stochastic systems described by Zakaj stochastic partial sifferential equationis proved by approximately minimum point theorem of E. Ekeland. The convexity and compactness of the set of control values is not assumed, and it is not necessary for the maximum principle about differentiability in control variables included in drift term of the stoch astic system and the integrand in index functional, and costate process satisfies the stochastic partial ...

在不假便定控制变量取值的集合是凸的和紧的，不要求随机系统的漂移项和指标泛函的被积函数关于控制变量具有可微性的情况下，用E，Ekeland的近似极小点定理证明了Zakai随机偏微分方程描述的随机系统的最优控制的最大值原理，和用很简洁的方法证明了协态过程满足一个随机偏微分方程。

In the course of the calendering, pressure bearing steel strip temperature is too high, the local Polish film flacherie it appropriate to reduce the pressure of the pressure and temperature light; or possibly finish and calendering technology conditions do not match the business card printing and membership card making products for layer on the surface cools, the same as the above band of light, laymch avulsing is poor technical condition so that it matches on, reducing the calender speed, to improve the optical layer on the light that is between the avulsing: same as above.

温度偏高，使制卡和会员卡制作品在压光过程中脱水过多，含水量降低，因而纸张纤维变脆，应降低压光的工作温度，并采取有效措施，保持制卡和会员卡制作品中—定的含水量；压光中压力过大，使制卡和会员卡制作品的延伸性和可塑性降低，韧性变性，可减少压光中的压力；若因为上光油的后加工适性不良，则应重新选择加工适性较好的上光油；后加工工艺条件选样不合适，可调整后加工工艺条件，使其与制卡和会员卡制作品压光后的适性相匹配。

However, the solutions of the Cauchy problem of the nonlinear hyperbolic system generally develop singularities in finite time even if the initial data are small and smooth.For this reason, solutions must be found in the space of discontinuous functions. Therefore, one can not directly use the classical analytic techniques that predominate in the theory of partial differential equations of other types. Instead, we construct approximate solutions via the singular perturbation methods. By using the compactness of the approximate solutions, we can obtain the existence of the solutions of original system.

然而一般而言，即使是在初值很小且光滑的情况下，非线性双曲型守恒律的Cauchy问题的解在有限时间内也会出现奇异性，为此，我们必须在不连续函数空间中寻找上述问题的解，因此对这类问题的研究，我们也不可能直接利用在其它类型的偏微分方程中占主导地位的解析方法来解决问题，而是通过奇异扰动法构造近似解，由近似解的紧性得到原问题解的存在性。

Even progress, which ought to superadd, for the most part only substitutes, one partial and incomplete truth for another; improvement consisting chiefly in this, that the new fragment of truth is more wanted, more adapted to the needs of the time, than that which it displaces.

甚至在前进运动中，那本当是累加性的，大部分也只是由一个偏而不全的真理去代替另一个偏而不全的真理；而进步之处主要只在新的真理片段比它所代替的东西更见需要，更为适合于时代的需求罢了。

Regarding to QTL analysis with single locus, segregation distortion would not affect QTL mapping, but regarding to analysis of digenic interactions for epistasis, the fewer distortion markers and larger size population would be needed.

对于单位点的QTL分析而言，偏分离标记一般不会影响QTL定位的位置和效应；对于两位点的上位性分析而言，则要求较少的偏分离标记和较大的群体。

The site of cord insertion was classified as velamentous, eccentric (more than 2 cm from the placental edge), or marginal (less than 2 cm from the placental edge), and a discordant cord insertion was considered to be the combination of a velamentous cord insertion in one fetus and an eccentric cord insertion in the other fetus.

脐带附着部位分为帆状、偏心性（超出胎盘边缘大于2厘米）、边缘性（超出胎盘边缘小于2厘米）以及不一致混合性附着，即一胎儿呈脐带帆状附着而另一胎儿呈偏心性附着。

The third part is to analyze the gender preference of peasants in village N, S and village B based on the data of fieldworks and SPSS. It is found that, without taking the birth control into consideration, son preference ratio of peasants in village N, S is 24% higher than that of village B. Suppose that only one child is allowed in one family, son preference ratio of peasants in village N, S is about 40% higher than that of village B.

研究发现，在不考虑胎次的情况下N、S两村农民的偏男系数比B村高24%，在假设只能生育一孩的情况下，N、S两村农民的偏男系数比B村高出将近40%；在生育行为方面，N、S两村农民明显偏好男孩，B村农民没有性别偏好；在孩子的抚育方面，N、S两村农民与B村农民没有显著性差异，均没有偏好男孩的表现。

Sinus bradycardia or sinus bradycardia with arrhythmia,sino-auricular block,sinus stopping beat with junctional abnormal beat occurred in15cases;Sinus bradycardia with ST-T changes occurred in10cases,ab-normal excitation（including ventricular,supraventricular premature beat with tachycardia）occurred in6cases the cardiac function of9cases were checked up:stroke volume,cardiac indexand ejection timewere normal or on the low side.The colour Doppler showed that excrescence in tricuspid valve of3cases and the diagnosis was infectivity bacterial endocarditis.

窦性心动过缓或窦性心动过缓伴不齐、窦房传导阻滞、窦性停搏伴交界性异搏共18例；窦性心动过缓伴ST-T改变11例；兴奋性异常（室性、室上性早搏伴心动过速）6例。9例心功能检查：心输出量、心脏指数、射血分数三项指标在正常偏低水平。3例心脏彩超三尖瓣赘生物，诊断为感染性细菌性心内膜炎。
