This article presents utilizing the asessment grading of X method of GB1223 75 “Stainless acid resistant steel intergranular corrosion test method” to solve the assessment problem of GB4334.3 84 “Stainless steel 65 percent nitric acid corrosion test”.

And accurate QRS detectionhas played a solid foundation for the other waveform identification. P and Iwaves detection can be realized by convenient magnitude-depended method. STsegment can be measurement by classical J+X method, and HRV analysis can beimplemented by the combination of linear and nonlinear methods.

A new method for detecting ST segment of electrocardiogram(ECG) signal has been developed to improve the detected precision. An algorithm based on wavelet transform(WT) has been researched to detect the characteristics of electrocardiogram(ECG),including the J point and the onsets of the T wave. The arithmetic puts the traditional J+X method and onsets of T wave detecting method together to attain the voltage of the ST segment.

On the basis of IDEF1X method, by summarizing the existing successful CIMS cases, quick definition of information model and the automatic glomeration of IDEF1X graphs are achieved under a coordinated working environment.

The nature of [Au(Sb 2S 4)] - adsorbed on kaolinite crystal surface has been studied by discrete variation X method (X-DV), one of the calculating methods in quantum chemistry.

The IDEF 1x method is used to build the fuzzy milling parameters supporting database model. And the GA approach is introduced to establish the optimization engine to provide the solution to this problem.

The analysis of 63 serum samples by both kits showed a good correlation (r=0.99) but the Serono (y) method gave values which were consistently greater (y=1.58x+4.89) than those of the DPC (x) method.

Finally it is shown that Fresnel fringes are smaller in the 2X method than in a comparable projection system.

It is shown that Cosslett's criticism on the 2X method is based partly on a misconception of the resolving power of the photographic film and partly on a fundamentally wrong comparison between projection and 2X method.

It was confirmed that the WISDAM-X method can evaluate the added resistance with sufficient relative accuracy and can be used as a design tool for ships.

The Moho depth calculated by inversing the gravity data of South China Sea region by means of matrix and 2-D sinx/x methods conforms better with actual data. The empirical formula used to estimate the Moho depth under South China Sea is presented in this paper. The selection of initial point in employing the matrix and sinx/x methods is approaced, and high frequency noises are also analysed in the paper.

In the corn(Zea mays.L.)plant population without dominant liguleless gene Lg3,crossing a inbred line with only recessive liguleless gene lg1 with another inbred line with only liguless recessive gene lg2 produced F1 plants which were all with ligules.Two phenotypes,ligule and liguleless,accured in F2.The data of observations were tested using chi-square(X) method.The result shows that ligulate character of corn is caused by the complemaentary action of two nonallelic dominant genes,Lg1 and Lg2.Liguleless character appears if either of the two gene loci is recessive homozygous.The ligule genetype mentioned in the paper cart be used in the explanation fo the separation phenomenon—the ratio of ligulate plants to liguleless one's is nine.to seven(or three to one).

在经过自交纯化证明没有显性无叶舌基因 Lg3的三个玉米自交系中,用只具有隐性无叶舌基因 Ig 1的玉米自交系,与只具有另一个隐性无叶舌基因 Ig 2的自交系杂交。F 1全表现有叶舌,F 2代分离出有叶舌和无叶舌两种表型。对观察值作了卡平方(X~2)测验.结果表明,玉米有叶舌性状系由两种非等位的显性基因 Lg 1和 Lg 2的互补作用支配。若任一座位发生隐性纯合,则表现无叶舌.文中提出的叶舌基因型,可用于解释有叶舌:无叶舌=9:7(或3:1)的叶舌性状分离现象.

This paper presents a gravity formula of a rectangular mass plane (eq. 1-2). Comparing-the gravity anomalies of this formula with the gravity anomalies of the rectangular parallelepiped (eq. 11), obtained that when the ratio of the thickness AH and the buried depth h of three dimensional geological body is less than 0.2-0.4, the gravity effect of rectangle mass plane is nearly equal to the gravity effect of rectangular parallelepiped (their maximum relatively erroris less than 1-3%). Therefore when △H/h is less than 0.4, we can use the simple gravityformula of rectangle mass plane instead of three dimensional geological body to compute the gravity anomalies. Based on this formula, this paper presents a method called "Compressed mass plane coefficient" to invert the 3-D discontinuity. The inverse coefficients of 21 (width)/D (depth) =1.0,1.1, 0.8 are given in Tab. 1, Tab. 3, Tab. 8 respectively. At first, the gravity data is inversed, using the inverse coefficients to get the surface density of each element of the rectangular mass plane. Then from the relation between surface density and mass density of each element (eq. 9), the thickness of each three dimensional element can be calculated and the approximate thickness of the interface tentatively obtained. Further improvements of the estimate-thickness of the density interface can be made by direct gravity computation of the model thus obtained and repeated adjustments of the results in order to minimize the difference between computed and observed gravity anomalies. In that way, it may be possible to get the better depths of the density discontinuity.To test this method of gravity inversion, the hypothetic model and an observed profile are introduced here as examples (Fig. 5, Tab. 7). In comparing with three dimensional sin x/x method, the results (Tab. 4, Tab. 5, and Fig. 6) indicate that the present method achieve good effects, lesser errors, and faster convergence.
